The PTFE reusable mask filter membrane is used as the protective layer. The fiber diameter is only a few tens of nanometers (90 nanometers for the new coronavirus). It directly uses the principle of physical isolation to filter viruses with hard core, with a filtration efficiency of more than 99% and excellent filtration performance. The excellence makes us feel more at ease.
Filter material fluctuations come from two sources. First, electret melt-blown and electrostatic cotton mainly provide filtration efficiency through static electricity, and static electricity itself has attenuation characteristics. Therefore, as time goes by, it may bring about filter material products. Reduction in filtration efficiency.
This point has been recognized by many people, but few people pay attention to the second point.
This is the difference between the products themselves, or product uniformity, which is the size of the deviation.
The surface of the ptfe reusable mask filter membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2.5 .
It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore diameter range of 0.1μm-0.5μm. It has the characteristics of high barrier efficiency, long service life, lightness and breathability. New direction for future mask development.
