New Material Technology Co., Ltd. gave full play to its professional advantages and developed a new type of mask filter material: ptfe nano mask filter membrane, and applied it to the production of high-performance membrane masks, using membrane technology achievements to shoulder the mission of fighting the epidemic. Take responsibility.
The types of filter materials vary widely. For example, gauze masks use ordinary skim gauze or ordinary gauze as the filter material, non-woven masks use non-woven fabrics such as melt-blown fiber and charged melt-blown fiber as the filter material, and composite masks use It is composed of a variety of filter materials, such as carbon fiber, non-woven fabrics and gauze composites.
Gauze has low filtration efficiency and low resistance, while the filtration efficiency and resistance range of general non-woven fabrics are 2.8%~99.8% and 9~157Pa respectively; the filtration efficiency and resistance of some electret masks are The ranges are 80.6%~99.9% and 4~72Pa respectively.
The barrier efficiency of the ptfe nano mask filter membrane is higher.
This is mainly due to the fact that it uses materials with smaller fiber diameters compared to traditional masks.
Generally speaking, the fiber diameter of the ordinary non-woven materials used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE film material is between 100 and 200 nanometers, which is much smaller than the above diameters. , so it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.
