The filtration effect of kn95 mask filter membrane
kn95 mask filter membrane is one of the materials with the best corrosion resistance in the world.
It is mainly made of suspended polytetrafluoroethylene resin, which is molded and sintered into a blank, and then turned and rolled.
A non-oriented film obtained by turning. The non-oriented film can be produced into a oriented film after calendering.
Masks can filter viruses, mainly from the key material-melt-blown non-woven fabric.
The material is polypropylene, which is made of extremely fine interwoven fibers. The average diameter of the fibers is about 2 μm. The material has been subjected to stationary surface treatment to make it electrostatically charged to enhance the adsorption capacity of dust and particulate matter.
The respiratory impedance of the kn95 mask filter membrane is only 60-70pa, and 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 with not wearing a mask. .
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 film materials, they can give users a more comfortable breathing experience.
The kn95 mask filter membrane manufacturer has advanced PTFE membrane production lines, coating and composite production lines, which are at the domestic advanced level.
The company’s products are widely used in various fields. The company has always implemented the purpose of “quality first, reputation first” and provides users with high-tech, high-quality, high-performance, and high-level products.
