With the spread of the global coronavirus (covid-19) epidemic, the price of raw materials for medical supplies has risen sharply. Among them, the core raw materials produced by masks are in great demand, and the price is in high demand.
On February 14, two companies, JXXC Nanofiber Technology Co., Ltd. and CCGQ Polyimide Material Technology Co., Ltd., were commended by the Chinese government in the form of documents for the innovation achievements of these two medical filter material technology companies.
Development of new anti-coronavirus (covid-19) nanofiber products. Through the unremitting efforts of many technology companies, within a month, polyimide nanoaerogel filter materials were continuously delivered to polyimide mask manufacturers Production line. It is understood that the polyimide nanoaerogel developed and produced by JXXC is unique in the world, meets the production requirements of civilian masks and has stable performance, and can be used for multiple times. The respiratory resistance index of the product can reach two directions below 90 The cost is also more than 20% lower than the current melt-blown cloth.
Because the diameter of polyimide nanofibers is very small, about one-thousandth of the diameter of the hair, the aerogel membrane formed has a very large specific surface area, and has a very strong static electricity, not only has excellent filtration performance , Such as filtering out dust, bacteria, viruses, etc., and having a large specific surface area, even after graphene is compounded, it can even efficiently adsorb a variety of gases, such as chemical poisonous gases and other harmful gases. break down. Aerogels and foams made of polyimide / graphene composite nanofibers can be widely used in aerospace, defense equipment, aircraft carrier ships, medical and health, environmental protection and other fields
