Using ptfe nano mask cloth as a protective layer, the fiber diameter is only tens of nanometers (new coronavirus 90 nanometers), directly using the principle of physical isolation, hard-core virus filtration, the filtration efficiency reaches more than 99%, and the excellent filtration performance makes We feel more at ease.
Since the outbreak of the new crown epidemic, the demand for masks has surged, causing the supply of filter material polypropylene (PP) meltblown cloth to exceed demand and the price to skyrocket.
Because the expanded polytetrafluoroethylene (PTFE) microporous membrane has a special fibrous microporous structure, when the micropore size is properly controlled, it can physically block viruses and PM2.5 haze particles. Therefore, some companies have combined PTFE microporous membrane with polypropylene non-woven fabrics and other materials to be used in masks, and produced PTFE microporous membrane composite filter materials (hereinafter referred to as PTFE mask membranes) to replace melt-blown cloth, which can compensate to a certain extent. market shortage.
PTFE nano mask cloth is a polymer waterproof material.
From a production point of view, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. From a quality point of view, it also has functional characteristics that other waterproof materials do not have.
The porosity of the film can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
