With the development of the epidemic, masks have become a necessity for people to go out.
The demand for masks is also very huge, because many masks are disposable and have to be thrown away after use, which has further caused a shortage of masks. For this reason, people hope to have one that can be reused. A mask would be fine.
Masks made of ptfe reusable mask filters can satisfy people’s wishes.
The English name of polytetrafluoroethylene is ptfe.
The surface of the polytetrafluoroethylene mask membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2.5.
It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is laminated on various fabrics and substrates using a special process. material, it can become a new type of filter material.
The PTFE reusable mask filter membrane made by mechanically stretching PTFE material can ensure the 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.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
