Filtration efficiency of disposable mask filter membrane
The disposable mask filter membrane uses unique paste extrusion and bidirectional stretching technology to produce fiber diameters below 100nm. The fiber cross-sectional area is only 1% of pp melt-blown fiber. These nanofibers are staggered to form The mesh structure has very good filtration efficiency, which is enough to effectively protect against bacteria and viruses, and has the characteristics of high efficiency and low resistance.
Ordinary medical or surgical masks are designed to prevent the germs carried by the person wearing the mask from being transmitted to other healthy people through droplets. Only N95 masks are designed to prevent the germs from the outside world from being transmitted to the person wearing the mask. Designed.
The material of ordinary medical or surgical masks cannot prevent tiny viruses from getting in, and it is not airtight. Germs can easily get in from the surrounding ventilated areas.
The dust removal efficiency of the disposable mask filter membrane can reach more than 99.9995%.
The minimum pore size of the film can reach 0.1um, which can capture most solid particles and liquid droplets. Since the pore size of the mask film is much larger than water vapor molecules, and polytetrafluoroethylene is a hydrophobic material, water droplets cannot penetrate the micropores, so It has good moisture permeability, breathability and waterproof properties.
The melting point is 164~170℃, and the products can be sterilized at temperatures above 100℃.
