The Mask Material Is Urgent! Sinopec Domineering Shout!

One of the main routes of transmission of the new crown virus is droplet transmission. Wearing masks has become a common understanding of isolating viruses and cutting the spread of viruses. It is also a necessary protective measure. So what material is the core material for making a mask?

A month ago, Na Tong Biotechnology (Beijing) Co., Ltd. had never produced a mask. As a company that manufactures three kinds of medical devices, the company has used the newly built 100 thousand level clean workshop in the new headquarters of the park for mask production.

Since February 2nd, the company has been preparing for the final production, and the company has only spent five days. The first batch of production has successfully produced twenty thousand masks. However, like other mask manufacturers, the problem of the shortage of melted cloth is coming. The price of melted spray cloth is high and quantity is small in the market, and the quality is also uneven. How can we make the enterprise stop working for second days? This has left the general manager well respected to the situation where tea and rice do not think and sleep all night.

Melt blown fabric

At the critical moment, the Beijing municipal government coordinated the Sinopec emergency to transfer a ton of melt blown cloth to them, thus relieving the urgent need. Not only that, Sinopec also established a raw material procurement docking group with them, and continuously provided about 6 tons of melt blown cloth. According to the calculation, the batch of materials can produce 8 million disposable medical masks.

In recent days, Zeng Jing Song is busy expanding production capacity. By the end of February, twenty devices have arrived at the workshop.

Ceng Jingsong, general manager of Na Tong Biotechnology (Beijing) Co., Ltd. The daily output of masks will be several times or even tens of times higher. However, the demand for other raw materials such as melted cloth and so on will still be in short supply from the perspective of future capacity growth.

Melted nonwoven fabric, commonly known as the "heart" of respirators, is the filter layer in the middle of the mask. It has good filtration, barrier, thermal insulation and adsorption properties. It is also an essential raw material for producing mask. In February 6th, "I have melted spray cloth, who has a mask machine" post has been heated up by netizens on the Internet. This news from Sinopec is somewhat surprising. Where does the melt blown cloth of Sinopec come from?

Melted spray cloth, in short, is composed of numerous tiny melt sprayed materials randomly distributed and bonded together. 1 tons of melt blown cloth can produce 1 million disposable medical masks, and melt blown fabric is made from melt blown materials produced in the process of petrochemical refining.

Sinopec spokesman Lv Dapeng: For example, Sinopec is a kind of wheat. Melt blown material is equivalent to a special kind of flour. Melted spray cloth is made of flour and flour, and the mask is the four process of holding a face piece and making a flower roll.

In February 8th, the task of producing melt blown materials dropped to the shoulders of Wang Suyu and colleagues of Petrochemical Industries Co in Yanshan. Although Wang Su Yu used to be a national standard maker for melt blown materials, 10 years ago, Yanshan Petrochemical also had a technological reserve for developing melt blown materials. However, when the production equipment had already passed, technical parameters such as melt sprayed material were no longer comparable.

In a short period of time, not only do polypropylene materials meet the requirements of melt blown nonwovens, but also the odor of degradation agents can be removed in the process of production, and the safety standards of mask production can be achieved. Every step of technological breakthroughs will take several months or even longer. But Wang Suyu and his colleagues managed to produce the first batch of melt sprayed materials in 72 hours. Today, Yanshan Petrochemical has produced a total of more than 20 tons of melt blown materials and sent 2.9 tons of finished products to the downstream melt blown nonwovens manufacturers.

Melt blown base material

Not only is Yanshan Petrochemical Company, but in February 23rd, Shanghai Petrochemical's emergency research and development of melt blown material was also successful in trial production, reaching 6 tons per day. These raw materials can be used to produce about 6 million disposable disposable medical masks. With the success of the melt blown material in petrochemical enterprises, many mask manufacturers will gradually get rid of the predicament of such materials. Lv Dapeng also revealed an important message that Sinopec will not only produce melt blown materials in the future, but also add 10 production lines to directly produce melt blown fabrics.

Sinopec spokesman Lv Dapeng: At this time, we must assume great responsibilities and great responsibilities. What the market needs, what we produce, what the market is short of, what we need to patch up, how fast we can produce masks, how fast we can produce, and how much we can produce. I think this reflects the social responsibility and political responsibility of a central enterprise and all enterprises.
