In the battle against the epidemic with science and technology, ptfe reproducible nanofilms came into being.
This year’s COVID-19 epidemic is fierce. Masks are important combat tools during epidemic prevention and resumption of work. Not all mouths can be well protected. Today we will take a look at a mask that is reusable and has good filtration. Efficient filter media.
According to industry insiders, masks are composed of three layers. The inner and outer layers are non-woven fabrics, and the middle layer is melt-blown cloth called the “heart” of the mask. The three layers of cloth act as a barrier through physical barriers and electrostatic adsorption principles. The role of dust and viruses.
Disinfection methods such as high temperature, alcohol, and radiation will destroy the inner structure of the melt-blown cloth, causing it to lose its filtering effect.
Therefore, ordinary masks cannot be reused.
The ptfe repeatable nanomembrane can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
The pore size of the material is small and the distribution is concentrated. Surface filtration is achieved to achieve a dust removal efficiency of 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.
