As various parts of the country announce the start of school time, the longest winter vacation in history has finally come to an end. Parents across the country who are “worrying about going to school and worrying about going to school” have begun to prepare their children’s back-to-school supplies, including Masks for children.
Today we will talk about the material ptfe nano mask filter membrane.
The design requirements of ordinary medical surgical masks are to block bacterial aerosol particles with a diameter greater than 3 microns. The pore diameter of the core layer of the mask is large and cannot perfectly physically isolate small particles of bacteria and viruses. Electrostatic adsorption is mainly used. Methods.
However, as the wearing time increases (such as 1 to 2 hours), due to the wearer’s breathing and other human activities, the mask becomes damp, its electrostatic adsorption capacity weakens, and the isolation effect gradually becomes worse.
The ptfe nanomask filter membrane can ensure the complete retention of bacteria and other impurities. It is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various bacteriophages and bacteria above 0.02um. Bacteria and particles.
Realizing surface filtration enables the dust removal efficiency to reach 99.9%~99.999%, which can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
It is a manufacturer of ptfe nano mask filter membrane environmental protection materials that specializes in R&D, production and sales.
