Behind The Mask Is The Most Complete Chain Of Supply Chain In The World.

We should focus on "prevention" to win the epidemic prevention and control. Open the Baidu search and enter the "Mask" two characters, showing up to 92 million 300 thousand results. Who has announced the new crown pneumonia epidemic as a "pandemic". Small masks are attracting billions of people around the world.

The small mask is a chain of industries and a complete industrial system behind it. It is the most complete industrial chain supply chain in the world today.

Raw materials: "cross boundary maintenance" of central enterprises, and the output of melt blown fabrics has been greatly improved.

The material of the mask is mainly non-woven fabric made of high melting point polypropylene material. Medical masks usually use multi-storey structures. The inner and outer layers are spunbonded nonwoven fabrics, and the middle layer is melted spray cloth.

Melt blown cloth is the key material in the respirator and the heart of the mask. Apart from blocking the larger dust particles, it can also absorb small dust, bacteria and virus droplets through the surface electrostatic charge. As the necessary raw material of filter function mask, 1 ordinary surgical masks should use 1 layers of melt spray cloth, and 1 N95 masks should use at least 3 layers of melt spray cloth, and 1 tons of melt spray cloth can make 1 million surgical surgical masks.

The capacity of China's melt blown cloth is not high. According to the data, the actual output of China's melt blown nonwovens in 2018 was 53 thousand and 523 tons, accounting for 1.8% of the total production of nonwoven fabrics.

The outbreak of the disease, so that a small minority of melt blown cloth has become a favorite market. Faced with the sharp expansion of demand and the shortage of masks and raw materials, central enterprises have "crossed the border to protect the plate".

The Research Institute of PetroChina has developed a series of tasks for R & D in a week. In the 8 day, Lanzhou petrochemical center completed the procurement and installation of key equipment, and tackled the related technical problems. In February 28th, China Petroleum self fusion polypropylene melt blown special material was successfully developed and produced 2 tons per day.

At 24 o'clock in March 6th, in the Yanshan petrochemical plant of the western suburb of Sinopec in Beijing, a huge spray nozzle poured out of white fibers and condensed into white cloth instantly. More than 600 employees of the participating parties continued to fight for 12 days and nights. Sinopec and the Yanshan Petrochemical melt blown nonwoven production line jointly constructed by the national machine and Heng Tian Group successfully launched a successful production of qualified products.

According to the State Council SASAC medical materials special working group news, as at 24 o'clock in March 6th, the central enterprise melt spraying cloth production reached 26 tons on that day. With the completion and commissioning of the new production line, the future output of the melt blown fabric will increase significantly, effectively easing the tension between supply and demand.

Market regulators also made decisive decisions. 10, reporters learned from the General Administration of market supervision, for the purpose of driving up the illegal price of melt blown cloth, the market supervision bureau and the Ministry of Public Security jointly investigated and prosecute the illegal behavior of disrupting the price order of the melted cloth market, and resolutely cut off the illegal chain of the price of melt blown cloth.

Key equipment: collaborative research and development, to complement the short chain of mask industry chain

When making melt blown fabric, high melting point polypropylene needs to be melted through high speed and high pressure hot air flow, then pulls out from the spinning hole, evenly spread on the collecting device under the guidance of airflow, and uses its own waste heat to bond to the net, and even by electret treatment, the melt blown cloth will have a certain charge on the belt to absorb the droplets by electrostatic force, so that the filtration efficiency of the melted cloth will be higher.

Melt blown fabric production line has huge investment, high technology content, complex equipment installation and high demand for workshops. These are the important factors that restrict the expansion of melt blown fabric production capacity. "It takes almost 8 million yuan to build a melted cloth production line, and the delivery date for domestic equipment is 3 to 4 months, and the import equipment is 6 to 8 months." A head of a technology company in Jiangsu told reporters.

In the mask industry chain, as the largest supplier of medical raw materials in China, Sinopec was originally the producer of the most upstream polypropylene raw materials. In order to guarantee the stable price of the middle melt melt cloth and the supply of downstream mask products, Sinopec decided to open up the industrial chain and fully intervene in the production of melt blown materials, melted cloth and mask. In Beijing, Sinopec's Yanshan Petrochemical 2 melted spray production line has been put into operation. In Jiangsu, Sinopec, Yizheng chemical fiber and 8 melt spraying production lines are being speeded up, and it is expected to be put into operation in mid April. The total investment of the 10 melted fabric production lines is about 200 million yuan. After the commissioning, the daily output can reach 18 tons.

Mask machine is another part of mask production, and also a short board of the mask industry chain. It will manufacture multi-layer non-woven fabrics by hot pressing, folding molding, ultrasonic welding, waste removal, ear and nose beam welding process, and so on.

Affected by the epidemic, the mask machine is also very scarce. Headquartered in Whampoa, Guangzhou, a number of backbone enterprises and their supply chain have set up a plane mask machine research team. It only takes a month to overcome difficulties and produce 100 masks machines. According to the Intelligent Company, which led the enterprise of the research group, the first plane flat mask machine was developed on the 10 day, and the pressure test was completed. The production of 100 sets on the 20 day was completed in the absence of past experience, the procurement of key parts and components is quite difficult, the technical personnel are scarce, and the pressure of epidemic prevention and control is very great.

The "1 out 2" high-end automatic mask machine developed by the aviation industry group has also been successfully launched in Beijing. The respirator is made up of 793 items and 2365 parts. Only one simple training can be used to achieve single person operation. Plans to achieve the 20 batch of production, including the prototype, including 24 units will be put into operation after the production of 3 million masks a day. Li Zhiqiang, President of the China Aviation Manufacturing Technology Research Institute, said: "the 24 mask machines are expected to be put into operation at the end of March.

While the relevant enterprises are continuing their efforts, the SASAC urgently promotes the development and production of key equipment such as medical masks, protective clothing and layering machines, and adopts the mode of "multiple enterprises, multiple plans and multiple paths". As of March 7th, 6 enterprises such as aviation industry group and China shipbuilding group have made 574 layering machines, 153 flat mask machines and 18 stereo respirators.

China is the world's largest producer and exporter of masks. Its annual output accounts for about 50% of the world's total. The Ministry of industry data shows that in 2019, the mask production in mainland China exceeded 5 billion, and 54% of the medical masks that could be used for virus protection. Therefore, China's production capacity is of great significance to global epidemic. Take the United States as an example, the United States is asking 4 overseas enterprises investing in the largest economies in Asia to return to produce medical protective products such as masks to protect the needs of the United States. But US health officials pointed out that raw materials for production related products are needed by the Chinese market. In fact, in the United States, mask manufacturers have moved almost all factories to the Chinese market, and 90% of American masks are imported from China.

Industrial chain: the hard core of the whole nation is resumed, and China's "cover" has made contributions to the world.

General medical masks are made up of spunbonded nonwoven fabric, melted nonwoven fabric, ear tape line and nose bar. Different kinds of gauze and activated carbon should be added according to different types. Seemingly ordinary components, however, involve basic industries such as chemical industry, textile, machinery, metallurgy, electronics and so on. They involve seven elements of raw materials, equipment, plant, capital, manpower, access permission and production cycle. Only China has the most complete mask industry chain, supply chain and production factors.

By February 29th, China's mask production has reached a new high: the national masks can reach 110 million Nissan, with a daily output of 116 million, effectively meeting the needs of epidemic prevention and control.

Behind the realization of the goal of "double billion" is the "hard nuclear recovery" of the whole nation. The state has also established a temporary collection and storage system to clarify the procurement and storage of key medical protective materials by the government. The focus of the epidemic prevention and control is to ensure that enterprises carry out the list management, give tax and financial support, set up a temporary production scheduling system for key enterprises, and send enterprises stationed in full strength to expand production, and the market supervision departments "do something special" to speed up the approval process and a series of measures. To create production conditions for enterprises.

The key to achieving the goal of "double billion" is to support China's sound industrial system and complete upstream and downstream industries. China has the largest and most complete and complete manufacturing system in the world. It is understood that at present, China has 41 industrial categories, 207 industrial classes and 666 industrial sub categories, and is the only country in the world that has all the industrial categories listed in the United Nations Industrial Classification.

At the news conference held by the Ministry of Commerce in March 12th, Li Xingqian, director of the foreign trade division of the Ministry of Commerce, pointed out that China would give all possible assistance to the countries concerned, especially the heavier epidemic countries and regions. The Chinese government will continue to support export enterprises to organize external supplies of medical supplies such as masks, and make due contributions to global epidemic prevention.
