The kn95 mask filter membrane is made of polypropylene, which is made of extremely fine interwoven fibers. The average diameter of the fibers is about 2 μm. The material has been treated with stationary surface to make it electrostatically charged to enhance the adsorption of dust and particulate matter. ability.
The respiratory impedance of the filter membrane of the kn95 mask is only 60-70pa, while the ordinary melt-blown non-woven mask is as high as 120-250pa. In comparison, the breathability of the film mask is already very good, but it certainly cannot be compared to not wearing a mask. Compare.
The wearing comfort of a polytetrafluoroethylene film mask is mainly determined by the air permeability and moisture permeability of the mask.
Thin film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of the film material, they can give users a more comfortable breathing experience.
? It has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
