At present, with the continuous optimization of Chinese prevention and control measures for COVID-19, the market demand for N95 masks has increased sharply, and orders for polypropylene melt-blown special materials, which are important raw materials for masks, have shown a blowout trend. On December 13th, we walked into Dawn Polymer, the national key guarantee enterprise for epidemic prevention and control, and experienced its struggle story of going all out to produce and supply epidemic prevention materials.

"After optimizing the policy, it means that the society's demand for melt-blown materials is greater, and the quality requirements of melt-blown materials are higher." Wu Di, deputy general manager of Dawn Polymer, said that the sales of polypropylene melt-blown special materials this month had increased significantly compared with last month, and the number of large customers had increased significantly. Moreover, orders are already in full plan before the Spring Festival, and the production workshop is working nonstop to increase and expand production capacity.

Although it is the cold winter season, the melt-blown material production workshop shows a busy scene full of enthusiasm. Employees patrol back and forth on the production line from time to time, and the automatic palletizing robot greatly improves the work efficiency. The loading and dispatching of the assembly line in the factory area is tense and orderly, and there is a long queue of trucks waiting to enter the factory on both sides of the road in the park. Hou Dianjun, production director of Dawn Polymer, said, "Everyone is full of energy and devoted to the front line of production with full enthusiasm to ensure the delivery of orders."

After 20 years of deep cultivation in the field of polypropylene melt-blown special materials, Dawn Polymer has the world's leading self-developed preparation technology. "Dawn's melt-blown material is made of high-grade homopolymer PP, and its fiber fineness is one-fifth of that of hair. It has higher filtration efficiency and plays a good barrier role." Chen Wenquan, deputy chief engineer of Dawn Polymer said.

It is worth mentioning that the long-acting additive formula independently developed by Dawn Polymer can electret the melt-blown fabrics, so that the fabric is filled with strong static electricity, which can electrostatically adsorb viruses. After a long period of storage, the electrostatic adsorption attenuation is reduced, but the filter efficiency retention rate of the masks produced in this way is higher. It not only meets the production standards of N95 masks, but also has the effect of strategic reserve and repeated use of masks.

According to reports, compared with disposable masks, the amount of melt-blown material used in N95 masks increases by about 3 times. 1 ton of polypropylene melt-blown material can produce 1-1.2 million disposable masks, but it can only be used for the production of 300,000 or 400,000 N95 masks. Tian Hongchi, general manager of Dawn Polymer, said, "We will give full play to the spirit and style of "Three Doings and Three Beings" of Dawn people, produce more and better melt-blown materials, and contribute to protecting the lives and health of people."
