It is reported that although existing drugs can prevent the HIV virus from further penetrating into the human body, they cannot clear the existing virus in the patient’s body. Even if patients receive effective treatment and the HIV virus in their bodies enters a dormant or latent state, they still carry HIV DNA or genetic material.

According to the BBC, the CRISPR gene editing technology used by the researchers is similar in principle to scissors, which can remove or inactivate HIV-infected cells by cutting DNA. This gene editing technology won the 2020 Nobel Prize in Chemistry.

At present, the scientific research process at the University of Amsterdam is still in the proof-of-concept stage, and it will take a long time for it to be truly applied to AIDS treatment.

Scientists believe that if this new technology can be further developed, it will be expected to eliminate all HIV in the human body, thereby curing AIDS. However, some virologists also said that the possible off-target effects and long-term side effects of this technology are worrying.

　　There are many kinds of refrigeration methods, such as gas expansion refrigeration, liquid gasification refrigeration, vortex tube refrigeration and thermoelectric refrigeration. Among them, liquid gasification refrigeration is the most widely used, and its working principle is to realize refrigeration by using the heat absorption of liquid gasification.At first, chilled water system It developed out of control and gradually opened up a sky of its own. https://puremind.com/product-category/puremind-air-conditioner/industrial-chiller/

　　

　　1, the working principle of air conditioning (mainly refrigeration, heating on the contrary):

　　

　　The high-temperature and high-pressure refrigerant discharged from the compressor flows through the outdoor heat exchanger through the four-way valve, and dissipates heat to the outdoor air through heating transfer, and the refrigerant changes from gaseous state to liquid state-throttles and depressurizes through capillary (or solenoid valve)-one-way valve-filter-two-way valve (outdoor high-pressure pipe)-enters the indoor heat exchanger to absorb heat (realize refrigeration)-outdoor three-way valve (outdoor low-pressure pipe). Complete a single-loop refrigeration cycle.

　　

　　2. Types of components in refrigeration system:

　　

　　The air conditioning refrigeration system is mainly composed of four parts and some auxiliary equipment in the refrigeration system.

　　

　　The four major pieces are:

　　

　　compressor

　　

　　condenser

　　

　　Throttle mechanism

　　

　　Evaporator composition.

　　

　　Auxiliary equipment:

　　

　　Oil separator;

　　

　　Drying filter;

　　

　　Liquid storage tank;

　　

　　Electromagnetic four-way reversing valve;

　　

　　Solenoid valve; Check valve

　　

　　3, the working principle of each component

　　

　　Compressor: As the “heart” of refrigeration system, it has an important influence on the performance, noise, energy consumption, vibration and service life of air conditioning. According to the principle of thermodynamics, it can be divided into volumetric type and velocity type.

　　

　　Volumetric type: a certain volume of gas is sucked into the cylinder and the internal volume of the cylinder is changed to realize gas compression and forced discharge.

　　

　　Speed type: make the inhaled gas get a certain speed, and then slow down, so that kinetic energy can be converted into pressure energy and then discharged. The growth of gas is converted from speed.

　　

　　one

　　

　　Scroll compressor: It is formed by meshing two vortexes of stator and rotor.

　　

　　Rotor compressor: it consists of spindle with eccentric wheel, cylinder, sleeve, air inlet, slide plate, spring, exhaust valve and exhaust port.

　　

　　Condenser: The condenser transfers the refrigerating capacity of the evaporator in the refrigeration system to the environmental medium (cooling water or air) together with the power consumption of the compressor. According to cooling, it can be divided into air-cooled type, water-cooled type and evaporative type. When cooling, it mainly radiates heat to the outside, and when heating, it absorbs heat to the outside.

　　

　　Evaporator: The main function of the evaporator is to boil and evaporate the low-temperature and low-pressure refrigerant liquid that has entered the throttle in the evaporator, absorb the heat of the cooled medium, and then become low-pressure saturated (usually overheated) vapor itself, which is continuously sucked away by the compressor. In other words, the evaporator is a heat exchange device that absorbs heat (that is, outputs cold energy).

　　

　　Throttle element: Throttle element is one of the four main elements in the refrigeration system. Its main function is to throttle and reduce the pressure of high-pressure liquid refrigerant, ensure the pressure difference between condenser and evaporator, and make the refrigerant entering the evaporator absorb heat and evaporate at the required low pressure, thus achieving the purpose of refrigeration and cooling. Adjust the refrigerant flow into the evaporator to adapt to the load change of the evaporator and make the system run normally.

　　

　　Capillary: It is a very thin tube, usually with an inner diameter of 0.5 ~ 2.5 mm and a length of 1 ~ 5 m.. When the refrigerant flows in the tube, it is necessary to overcome the resistance in the tube, which naturally produces a certain pressure drop.

　　

　　Capillary characteristics: Because it is in the normally open state, when the compressor stops, the high and low pressure can be quickly balanced, which is conducive to the compressor starting again. Simple structure, convenient manufacture and low price. For the heat pump system, there is no import and export problem in the throttling process of refrigerant in capillary [this article source: refrigeration encyclopedia WeChat official account” target=_blank>. Using capillary refrigeration system, the performance of the unit is very sensitive to the refrigerant charge. When the operating conditions of the refrigeration system change, the capillary tube has poor ability to adjust the refrigerant flow. Due to the small inner diameter of capillary and long pipeline, it is easy to be blocked, so attention should be paid to the drying and cleaning of the system. Generally, a dry filter is set in front of the capillary to prevent clogging.

　　

　　Thermal expansion valve: the regulating valve that controls the liquid supply of evaporator, and it is also the throttle valve of refrigeration device. Thermal expansion valve uses the change of superheat of refrigerant at evaporator outlet to adjust the flow. According to different structures, it can be divided into internal balance type and external balance type.

　　

　　Disadvantages of thermal expansion valve: low control precision and limited adjustment range. The diaphragm deformation of valve body is limited, which makes the change range of valve needle opening smaller, so the adjustment range of flow is small. When large flow regulation is required, it cannot be met. The high-temperature gas at the place where the signal feedback has a lag evaporator must first heat the shell of the temperature sensor, which has a large thermal inertia, leading to the lag of the reaction.

　　

　　2

　　

　　Electronic expansion valve: the application of electronic expansion valve overcomes the shortcomings of thermal expansion valve and provides conditions for the intelligence of refrigeration device. The electric signal generated by adjusting parameters is mainly used to control the voltage or current applied to the expansion valve, so as to achieve the purpose of adjustment, so that the control system of the electronic expansion valve is complicated and the price is high.

　　

　　Electronic expansion valve classification:

　　

　　Electromagnetic electronic expansion valve;

　　

　　Electric electronic expansion valve.

　　

　　4. Auxiliary equipment of refrigeration system

　　

　　Oil separator: The high-pressure gas (gaseous working medium and lubricating oil) from the compressor enters the oil separator to separate the lubricating oil from the working medium gas and flows down along the inner wall of the cylinder. The working gas is led out of the oil separator from the central pipe through the porous baffle. The separated lubricating oil is concentrated in the lower part of the oil separator and can be discharged regularly, or the lubricating oil can be automatically returned to the crankcase of the compressor by using the ball valve.

　　

　　Drying filter: The function of drying filter is to absorb moisture in refrigeration system, prevent impurities in the system from passing through, and prevent the pipeline of refrigeration system from being blocked by ice and dirt. Because the most easily blocked part of the system is the capillary (or expansion valve), the drying filter is usually installed between the condenser and the capillary (or expansion valve).

　　

　　Liquid storage tank: During the operation of the refrigeration system, the circulating amount of refrigerant in the system will change due to the change of working conditions or the adjustment of refrigeration capacity. Setting the liquid storage tank can balance and stabilize the refrigerant circulation in the system by using the liquid storage capacity of the liquid storage tank, so that the refrigeration system can be in normal operation. In addition, when a component in the refrigeration system fails and needs to be dismantled and repaired, the system refrigerant can be recovered to the liquid storage tank through certain operation methods.

　　

　　The liquid storage tank is generally arranged between the condenser and the throttling element, so that the refrigerant liquid in the condenser can smoothly enter the liquid storage tank. The position of the liquid storage tank should be lower than that of the condenser.

　　

　　Electromagnetic four-way reversing valve: after the electromagnetic coil is energized, it changes the action direction of the valve block in the valve body and changes the flow direction of the refrigerant. So as to achieve the purpose of cooling or heating.

　　

　　three

　　

　　Solenoid valve: Solenoid valve is usually installed in front of the expansion valve to directly control the amount of refrigerant entering the evaporator. It can also be installed before the compressor unloading cylinder to control the unloading of the compressor cylinder.

　　

　　There are two kinds:

　　

　　Direct opening and closing solenoid valve;

　　

　　Indirect solenoid valve.

　　

　　One-way valve: The one-way valve is usually connected in parallel with the auxiliary capillary, and the two are connected in series with the main capillary. One-way valve is a tubular element with a movable spherical or hemispherical plug made of stainless steel or nylon. Combined with capillary tube, it can adapt to two different operating conditions of refrigeration and heating.

　　

　　5. Types and States of Refrigerant

　　

　　Air conditioning refrigerants mainly include R22, R410A and R32.

　　

　　R22 is a medium-temperature refrigerant, with the standard of -40.8 degrees, the solubility of water in R22 is very small, and it is mutually soluble with mineral oil, and R22 does not burn or explode, with little toxicity and strong permeability.

　　

　　R410A is a HFC refrigerant which is composed of R32 and R125 by 50% and 50% by mass. [This article comes from WeChat official account, a refrigeration encyclopedia” target=_blank>, which belongs to a near azeotrope, and its thermodynamic properties are very close to that of a single refrigerant. Compared with R22, R410A’s condensation pressure is increased by 1.6 times, and it is a high-pressure refrigerant, so it is necessary to improve the compression strength of the system.

　　

　　R32 is the abbreviation of difluoromethane, which is a kind of coolant with zero ozone loss potential. It is a gas at room temperature and a colorless and transparent liquid under its own pressure. It is soluble in oil and insoluble in water, and it is an energy-saving and carbon-reducing environment-friendly non-toxic refrigerant, but it is flammable and explosive!

　　

　　6. Refrigerant status

　　

　　Saturated refrigerant: Vapor-liquid conversion in saturated refrigerant is in transport equilibrium, and liquid and gas at this time are in saturation.

　　

　　There is a one-to-one correspondence between saturation temperature and saturation pressure, and the saturation pressure increases with the increase of saturation temperature, and one of them will change and the other will change accordingly. In the system, the refrigerant in the evaporator absorbs heat and the refrigerant in the condenser releases heat, where the refrigerant is saturated.

　　

　　Superheat: Under a certain pressure, the temperature of superheated steam exceeds the saturation temperature.

　　

　　Overheating: the temperature of refrigerant vapor in superheated refrigerant is higher than the saturation temperature under the corresponding saturation pressure, and the liquid refrigerant will overheat after evaporation. In the case of overheating, there is no one-to-one correspondence between the temperature and pressure of refrigerant gas.

　　

　　Near the outlet of the evaporator, the refrigerant continues to absorb heat after complete evaporation and becomes superheated refrigerant with a temperature higher than the saturation temperature. The refrigerant enters the compressor through the suction pipe in case of overheating.

　　

　　Supercooling: The liquid temperature of the supercooled refrigerant is lower than the saturation temperature at the corresponding saturation pressure, and supercooling will only occur when there is no steam in the fluid refrigerant. In the case of supercooling, there is no one-to-one correspondence between the temperature and pressure of refrigerant liquid.

　　

　　Between the outlet of the condenser and the throttle valve, the refrigerant may continue to cool exothermically and become supercooled after condensing into saturated liquid.

Local time 18, the Argentine central bank confirmed that the face value of 10,000 Argentine pesos and 20,000 Argentine pesos will be officially put into circulation in June this year.

In recent years, the face value of banknotes issued by Argentina has been increasing due to persistent high inflation and serious currency depreciation. In 2016 and 2017, Argentina issued banknotes with a face value of 500 pesos and 1000 pesos respectively. The 2000 peso note, which went into circulation in May last year, is currently the largest denomination note on the Argentine market.

Argentina’s monthly inflation rate reached 132% in February, with a cumulative inflation rate of 2762% in the past 12 months, according to data released by Argentina’s National Bureau of Statistics on the 12th. (gong Xiangcheng, a reporter from the front desk)

Buenos Aires, March 19 / PRNewswire-FirstCall-Asianet /– what is the effect of the reform since Argentine President Mile took office 100 days ago?

Press gallery h Wang Zhongyi

Since taking office in December last year, Argentine President Mile has launched a series of shock therapy reform measures aimed at saving the economy, with a view to reducing the fiscal deficit and controlling inflation. Among them, the two major reform measures proposed by the Mile government are still pending due to parliamentary procedures.

At present, Argentina has achieved a fiscal surplus for two consecutive months, and the inflationary pressure has eased somewhat, but the difficulties such as the increase in unemployment, the decline in industrial production and rising prices still exist. Analysts believe that whether the reform can be supported by Congress, whether inflation can be controlled and whether public anxiety can be calmed down are still challenges facing the Mile government.

The prospect of reform is uncertain.

In his first month in office, Mile launched two major reform measures, namely, the necessary emergency decree on the basis of Argentina’s economic reconstruction and the comprehensive bill called the foundation and starting point of Argentine freedom, covering the amendment or repeal of hundreds of laws and regulations, respectively, aimed at relaxing government and legal controls on economic names, reducing the fiscal deficit and facilitating import and export trade. In addition, Mile also devalued the Argentine peso significantly.

On March 14, the Argentine Senate voted down the necessary emergency decree signed by Mile, which will then be submitted to the Argentine House of Representatives for consideration and vote. According to Argentine law, even if the decree is rejected by the Senate, it can take effect as long as the House of Representatives votes to pass it; if the House of Representatives votes to reject it, the decree will be completely null and void. The comprehensive bill introduced by Mile has not been passed by Congress before, and is now planning to amend the provisions of the bill to be submitted to Congress for consideration.

Analysts believe that the resistance to Mile’s reform mainly comes from the left and trade unions. at present, as the ruling party and left-wing opposition parties do not have a majority in both houses, Mile still needs to win the support of centrist parties to promote the implementation of the reform.

Sun Hongbo, associate researcher at the Institute of Latin American Studies of the Chinese Academy of Social Sciences, believes that the Mile government intends to carry out a systematic and radical reform, but the relevant reform measures currently face various political checks and balances. Generally speaking, the Mile government is facing the constraints of many forces, such as the ruling coalition, left-wing political parties, local governments, trade unions and so on, and there is a lot of uncertainty about the prospect of its radical reform.

The plight of people’s livelihood needs to be alleviated.

Recently, a lot of news has been seen as positive by the Argentine government: Argentina’s central bank cut its benchmark interest rate to 80%, a fiscal surplus for two consecutive months, an easing of inflationary pressures, the International Monetary Fund approved a further $4.7 billion loan to Argentina, and Argentina completed a debt swap of more than $50 billion. Despite this, Argentine people are still plagued by rising unemployment, rising prices and other problems.

In March, Argentines ushered in the day to return to work and start school, but many people were laid off. Argentine media reported that companies said sales had fallen sharply and could not afford to hire so many employees. The dark clouds of unemployment, poverty and rising prices hang over the Argentine people.

Argentine sociologist Marcelo Rodriguez said the unemployment rate in Argentina is expected to rise in the future as more than 50, 000 jobs have been lost as a result of government cuts, layoffs and no longer injecting funds into public projects.

According to a recent report by Argentina’s Financial Circle, the latest report of the Argentine Federation of Industries showed that in January this year, Argentina’s industrial production index fell to 299%, the lowest level on record, and was in a contraction range of less than 50% for the seventh month in a row. The report said that the output of more than half of the small and medium-sized enterprises surveyed declined, and several sets of data showed that the plight of industrial production in Afghanistan intensified, with small and medium-sized enterprises bearing the brunt.

A staff member of the United Nations Children’s Fund (UNICEF) office in Argentina recently said that in the first quarter of 2024, the poverty rate of children and adolescents in Argentina will reach about 70%, and the rate of extreme poverty will reach 34%.

Since the beginning of this year, large-scale strikes and demonstrations have broken out in Argentina many times to oppose the reform measures of the Mile government. On March 18, a number of trade union organizations in Argentina launched a march in the capital Buenos Aires and other cities across the country. In January, a number of national trade unions and left-wing organizations in Argentina also held a national strike to protest against the Mile government’s reform measures ignoring the rights and interests of labor and social vulnerable groups, resulting in the suspension of services in banks, gas stations, airports, aviation, sanitation and other industries in many parts of Argentina.

The economy faces the challenge of stagflation

Argentine economist Gustavone believes that the Mile government has reversed the declining trend of Argentine dollar reserves after 100 days in power, but the country’s economy still faces the challenge of stagflation.

Inflation in Argentina was 132 per cent in February, down from 206 per cent in January and 255 per cent in December, according to the Argentine National Institute of Statistics and Census. The cumulative inflation rate in the past 12 months reached 2762 per cent. Rosendo Fraga, a researcher at Argentina’s National Institute of moral and political Sciences, believes that although the monthly inflation rate has decreased, inflation is still at a high level.

The International Monetary Fund (IMF) released a report on January 30 predicting that Argentina will face recession and rising inflation in the context of a sharp adjustment in economic policy. The report predicts that Argentina’s economy will contract by 28% in 2024.

Argentina’s TN news channel recently quoted Moody’s investor service, an international rating agency, as saying that the Argentine economy is expected to contract by 5% in 2024, far more than the 25% forecast in November 2023. In terms of inflation, Argentina’s inflation rate is expected to exceed 280% in 2024 and still exceed 220% in 2025. (source: Xinhua)

　　It’s getting hot, and it’s time to turn on the air conditioner. But can you really use air conditioning? Is it only cooling in summer and heating in winter? Air-conditioning remote controllers are generally equipped with a variety of use modes, and different modes have different use effects. Let’s take a look at it.understand ac inverter air conditioner In order to better serve customers and reflect the core competitiveness of products. https://puremind.com/product-category/puremind-air-conditioner/split-air-conditioner/

　　

　　Cool feeling mode

　　

　　Applicable people: afraid of heat and cold.

　　

　　Blowing the air conditioner in summer is cool, because the room temperature is lowered, and because the cold air blown by the air conditioner blows on the body, it plays the role of an electric fan.

　　

　　The principle of the “cool feeling” function is simple: control the angle and speed of the air outlet to prevent the air conditioner from blowing at people-the traditional way is to adjust the angle of the air deflector and the speed of the fan, and the new air conditioner is even equipped with an infrared probe to prevent the wind from blowing directly at people, which is very friendly to people who are afraid of cold stars.

　　

　　Air supply mode

　　

　　Applicable scenario: when it is not too hot

　　

　　Air conditioning is a combination of “cooling/heating+fan”, and the “air supply” function is to turn on the fan instead of starting the compressor, electric heating wire and other temperature-related components of the air conditioning.

　　

　　If you want to improve the air quality, breathe and smell, you need air conditioning with fresh air system.

　　

　　Eco mode

　　

　　Applicable scene: before going to sleep

　　

　　”eco”, the abbreviation of economic, is also called “energy saving” mode.

　　

　　It is suggested that the air conditioner can be changed to this mode before going to bed. When you fall asleep at a comfortable room temperature, the air conditioner will change the temperature, increasing it in summer and decreasing it in winter. In short, it will reduce the power consumption until it is completely turned off, that is, the “sleep” mode.

　　

　　Dehumidification mode

　　

　　Applicable scene: hot and humid weather

　　

　　Both “dehumidification” and “refrigeration” modes will produce refrigeration effect. The difference is that after the “dehumidification” mode is turned on, the air conditioner will appropriately cool the indoor air, let the water vapor condense into water, and then discharge it to the outside-reducing the indoor humidity, and people’s body temperature will be cooler. The main purpose of the “refrigeration” mode is to reduce the indoor temperature, and the water vapor in the condensed air is an incidental effect.

　　

　　From the effect point of view, after opening the “dehumidification” mode, although the air conditioning temperature is not very low and it does not consume too much electricity, it will be more comfortable.

　　

　　It should be noted that this function is only effective in areas with humid climate. If you live in a dry area, this function is not recommended.

　　

　　Automatic mode

　　

　　Applicable people: people who need indoor constant temperature and people who use company air conditioning.

　　

　　To choose this mode, you need to set a temperature first, say 26 degrees Celsius. If the room temperature is lower than 26 degrees Celsius, the air conditioner will start heating; If the room temperature is higher than 26 degrees Celsius, the air conditioner will start to cool.

　　

　　Auxiliary heating mode

　　

　　Applicable scene: when you just enter the house in winter and are about to be frozen.

　　

　　There are two ways to heat by air conditioning. One is a porter who relies on heat-compressor. From the thermodynamic point of view, using compression mechanism to save heat and electricity, but the heating speed is slow, and when it is particularly cold outdoors, such as below 0 degrees Celsius, the heating efficiency will become low.

　　

　　The other is the producer of heat-electric heating wire. “Auxiliary heating” is the option of turning on the electric heating wire, which can assist the compressor to achieve the effect of rapid heating. After the room temperature reaches the set temperature, just keep the temperature by the compression mechanism. At this time, the “auxiliary heating” function can be turned off in order to save electricity.

　　

　　Everyone can use these functions as much as possible. After all, we spent thousands of dollars to buy an air conditioner, and if we don’t drain all its functions, we will lose money!

Geneva, July 17 (Reporter Chen Binjie) The ninth World Trade Organization review of China’s trade policy held its first day meeting in Geneva, Switzerland on the 17th.

The review lasted for two days. Vice Minister of Commerce Li Fei led a Chinese delegation to attend the review meeting. Li Fei said in his speech that the WTO is an important pillar of multilateralism and an important stage for global economic governance. China adheres to the path of Chinese-style modernization and promotes high-quality development. Since the last review in October 2021, China has actively practiced true multilateralism, continued to play an important role in global development, and brought more opportunities to the world through its ultra-large market. China strengthens South-South cooperation, implements global development initiatives, and supports developing members in accelerating development.

Li Fei emphasized that China will firmly deepen high-level opening up to the outside world, further reduce import tariffs, improve the level of trade facilitation, continue to expand the opening up of service sectors, and relax market access for foreign investment; China will continue to promote deep-seated reforms and give full play to the market’s role in resource allocation. Decisive role, promote a better combination of effective markets and promising governments, and promote innovative, green, digital and inclusive development.

Li Fei pointed out that China has fully and deeply participated in the WTO reform negotiations, promoted the WTO to better respond to global challenges, supported the inclusive development of the multilateral trading system, and helped developing members better integrate into global value chains.

Representatives of WTO members spoke highly of China’s positive contribution to promoting global economic growth and maintaining the multilateral trading system, and appreciated China’s policy measures to deepen domestic reforms and further expand opening up. Developing members highly appreciate China’s practical actions to support it, especially in supporting the least developed members in accelerating development and further integrating into the multilateral trading system.

Member representatives pointed out that China’s economy has shown strong resilience under multiple external challenges, growing by 52% in 2023, and is the most important driving force for global economic recovery after the COVID-19 epidemic. China is the most important trading partner of many members. In recent years, China has continued to promote trade and investment liberalization and facilitation by reducing tariffs, optimizing customs clearance procedures, and issuing negative lists.

Member representatives highly recognized that China continues to promote market-oriented reforms, promotes green economic transformation and development by strengthening technological innovation and other means, and makes outstanding contributions to global low-carbon and green development and addressing climate change.

Member representatives stated that China is an important and responsible member of the WTO and has made significant contributions to promoting discussions on topics such as investment facilitation, e-commerce negotiations, domestic regulation of trade in services, prevention and control of plastic pollution, and fishery subsidies, supporting the reform of the dispute settlement mechanism and promoting the restoration of the Appellate Body.

Trade policy review is one of the three core functions of the WTO and an important mechanism for WTO members to understand each other’s economic and trade policies. Before the meeting, China received more than 1000 written questions from 44 members and provided answers to all questions on time in accordance with the rules.

　　In the market, we can often see shelves filled with a dazzling array of products. When the same product is packaged differently, the product packaged in tinplate can will become the first thing consumers want to know. In fact, we have to understand it, first of all, the product has exquisite packaging, and secondly, because of the practicality of the tin box.Mentioned in the article tin cosmetic packaging Born with strong vitality, you can turn a cocoon into a butterfly and become the best yourself after wind and rain. https://tinboxmate.com/products/

　　

　　Generally speaking, when the goods inside the tin box are used up, we can also use the tin box as a storage box, which is one of the reasons why we want to use the tin box to package the product. It is also the embodiment of the environmental protection of the iron box.

　　

　　Everyone knows that tin boxes are durable and environmentally friendly, but most people don¨t have a deep understanding of the materials of tin boxes. In fact, the tinplate box packaging products we see on the market are mainly made of two tinplate materials. There are two main types of iron cans: tinned iron cans and frosted iron cans. Tinned iron is also called white iron or ordinary iron, its price is cheaper than frosted iron, there is no frosted surface, after printing a layer of white on the surface, you can print a variety of exquisite patterns, in the strong light can reflect the light, giving people a dazzling feeling, not only high-end, but also affordable, so the iron cans made by tinned iron printing are very popular with customers.

　　

　　Another tinplate material, frosted iron, also known as silver-glossed iron, has a sandy grainy surface, so people usually call it frosted iron, and its price is the most expensive tinplate material. The tensile force and hardness of matte iron are less than those of tinned iron, so some specifications of tinplate are not suitable for making high-elasticity packaging products.

　　

　　The Tinned iron cans box

　　

　　Everyone has different preferences, some people like tinplate tinplate boxes, because it can be customized with beautiful printing patterns, some people like frosted tinplate cans, because they like the texture of iron materials, tinplate cans can actually meet customers¨ different aesthetics and pursuits.

United Nations, July 16 (Reporter Wang Jiangang) Fu Cong, Chinese Permanent Representative to the United Nations, spoke at the Security Council’s open debate on international order and multilateral cooperation on the 16th, calling on the international community to promote the construction of a more just and reasonable international order, safeguard sovereign equality, and Let every country find its place in the multipolar system, play its due role, and jointly promote an equal and orderly world multipolarization.

Fu Cong said that countries should respect each other, take into account each other’s core interests and major concerns, respect the development paths and institutional models independently chosen by the people of all countries, and not interfere in other countries ‘internal affairs; create common security, be based on the objective law that security is indivisible, and adhere to Resolve disputes through dialogue, resolve differences through consultation, and build a more balanced, effective and sustainable security architecture; Promote common development, promote inclusive economic globalization, accelerate the implementation of the 2030 Agenda for Sustainable Development, and strive to achieve the goal of leaving no country or anyone behind.

Fu Cong called on all countries to uphold fairness and justice, safeguard the authority of the United Nations and international law, advocate a global governance concept of extensive consultation, joint contribution and shared benefits, enhance the representation and voice of developing countries; demonstrate openness and inclusiveness, promote equal dialogue, exchanges and mutual learning among different civilizations, promote mutual understanding among people of all countries, and promote common values for all mankind.

Fu Cong pointed out that the real intention of some countries in the so-called rules-based international order is to create an alternative system outside the existing international legal system and seek legitimacy for double standards and exceptionalism. There is only one order in the world, that is, an international order based on international law. There is only one set of rules, that is, the basic norms of international relations based on the purposes and principles of the United Nations Charter.

Fu Cong said that NATO, as a well-known regional military group left over from the Cold War, seeks to expand its sphere of influence, is keen to create false narratives, add fuel everywhere, incite camp confrontation, and even blame and blame domain name foreigners on the Ukraine issue. This runs counter to the international community’s efforts to promote peace and talks. History has fully proved that wherever NATO’s black hands extend, turmoil and chaos appear. China advises NATO and some countries to reflect on themselves and stop being troublemakers who harm others and undermine common security.

Fu Cong said that common development and common security complement each other and are the foundation of a good international order, in which development is the overall key to solving all problems. Some countries generalize the concept of national security, build small courtyards and high walls, impose indiscriminate unilateral sanctions, and disrupt the global production and supply chain, which will ultimately lead to a situation of double lose and multiple lose. The international community must resolutely resist this erroneous practice.

Fu Cong said that Chinese leaders followed the trend of the times and proposed the Five Principles of Peaceful Coexistence, which fully reflected the spirit of the Charter and created the basic norms of international relations that countries, big or small, strong or weak, regardless of East and West, should respect each other and treat each other as equals., also provides an important ideological foundation for promoting the development of the international order in a more just and reasonable direction. Chinese leaders ‘proposal to build a community with a shared future for mankind is an inheritance and promotion of the purposes and principles of the United Nations Charter and the Five Principles of Peaceful Coexistence under the new situation.

　　Everyone knows that tin boxes are durable and environmentally friendly, but most people don¨t have a deep understanding of the materials of tin boxes. In fact, the tinplate box packaging products we see on the market are mainly made of two tinplate materials. There are two main types of iron cans: tinned iron cans and frosted iron cans. Tinned iron is also called white iron or ordinary iron, its price is cheaper than frosted iron, there is no frosted surface, after printing a layer of white on the surface, you can print a variety of exquisite patterns, in the strong light can reflect the light, giving people a dazzling feeling, not only high-end, but also affordable, so the iron cans made by tinned iron printing are very popular with customers.

　　

　　Another tinplate material, frosted iron, also known as silver-glossed iron, has a sandy grainy surface, so people usually call it frosted iron, and its price is the most expensive tinplate material. The tensile force and hardness of matte iron are less than those of tinned iron, so some specifications of tinplate are not suitable for making high-elasticity packaging products.

Beijing, 12 Mar (Reporter Ma Zhuoyan, Cheng Xin) Foreign Ministry spokesman Wang Wenbin said on the 12th that through this year’s two sessions, the international community has seen a China that is moving forward steadily, pioneering and innovative, open and confident, and cohesive. We are more optimistic about the great potential of China’s economic and social development, and expect that China’s high-quality development will bring more opportunities to the world.

At the regular press conference on that day, a reporter asked: over the past week or so, international public opinion has continued to focus on the two national sessions. A number of foreign media quoted the analysis of international institutions and experts as saying that the two sessions sent a positive signal that China’s economy is picking up. Does the spokesman have any comment on this?

Wang Wenbin said: the annual NPC and CPPCC sessions are not only a major event in China’s political life, but also an important window for the international community to observe the direction of China’s major policies. Whether it is the expected target of GDP growth of about 5% put forward in this year’s government work report, or the key words such as high-quality productivity, high-quality development, high level of opening to the outside world, and so on, have aroused heated discussion in the international media. Through the two sessions of the National people’s Congress this year, the international community has seen a China that is moving forward steadily, pioneering and innovative, open and confident, and cohesive, and is more optimistic about the great potential of China’s economic and social development. It is expected that China’s high-quality development will bring more opportunities to the world.

Wang Wenbin said that the government work report puts forward a growth target of about 5%, which shows that China’s economy is resilient, has great potential and is full of vitality. This goal is not only higher than the previous IMF and World Bank forecasts for China’s economic growth this year, but also far higher than the IMF’s growth forecasts for the United States and Europe. International media commented that at a time when the world economy is full of uncertainty, China’s economic growth target of about 5% is ambitious. Since the beginning of the year, China’s economy has continued to accumulate factors for the better. During the Spring Festival holiday this year, there were 229.3 billion cross-district domain name flows in China, and domestic tourists spent a total of 63.2687 trillion yuan, an increase of 77 percent over the same period in 2019. In the first two months of this year, China’s imports and exports of goods totaled 661 trillion yuan, an increase of 87 percent over the same period last year. China’s economy continues to pick up and is expected to get off to a good start in the first quarter.

He said that the important exposition of new quality productive forces has guided China’s economy toward a new direction. When participating in the deliberations of the Jiangsu delegation, General Secretary stressed the need to firmly grasp the primary task of high-quality development and develop new-quality productive forces in line with local conditions. This year’s government work report also proposed for the first time to vigorously promote the construction of a modern industrial system and speed up the development of new-quality productive forces. Last year, China’s new exports of electric vehicles, lithium batteries and photovoltaic products exceeded trillion yuan, an increase of nearly 30 percent over the same period last year; the development of the digital economy was accelerated, and the penetration rate of 5G users exceeded 50 percent. The number of international patent applications submitted by Chinese applicants through the Patent Cooperation Treaty ranked first in the world for four consecutive years. New quality productivity has been formed in practice and has shown a strong driving force and supporting force for high-quality development.

Wang Wenbin said: the new measure of opening up to the outside world at a high level shows China’s determination to share opportunities with the world. The government work report proposes to open wider to the outside world at a high level and promote mutual benefit and win-win results. China will take the initiative to dovetail with high-standard international economic and trade rules, steadily expand institutional opening up, promote a stable increase in the quality and quantity of foreign trade, step up efforts to attract foreign investment, promote high-quality co-construction, Belt and Road Initiative, and deepen multilateral, bilateral and regional economic cooperation. In January this year, 4588 new foreign-invested enterprises were established in China, an increase of 744 per cent over the same period last year. According to the latest survey of the German Chamber of Commerce in China, 91% of German enterprises will continue to take root in the Chinese market. The American Chamber of Commerce in South China reported that 76% of the companies surveyed planned to reinvest in China this year. More and more multinational companies realize that to invest in China is to invest in the future.

The blueprint has been drawn and the trumpet has been sounded. We have the confidence, conditions and ability to achieve the goals and tasks of economic and social development for the whole year. Wang Wenbin said: China’s economy is getting bigger and bigger, its muscles and bones are getting stronger and stronger, and it will certainly ride out the storm and look forward to the future.
