Since the outbreak of COVID-19, kn95 masks can effectively intercept respiratory droplets and tiny airborne particles carrying pathogens. Filter membrane has become an important material for making masks. Let’s learn more about it.
KN95 and N95 masks have the same level of protection, but they just follow the testing standards of different countries. KN95 masks follow Chinese standards, and N95 masks follow American standards. The protection efficiency of both against non-oily particles (experimental sodium chloride particles) is no less than 95%.
The kn95 mask filter membrane has good antibacterial and water-repellent properties. Its characteristic is that the human body’s sweat can be emitted outwards, but outside water, bacteria and viruses cannot enter. There are about 1 billion pores per square centimeter, with a porosity of more than 90%. The pore diameter is about 0.2 μm, which is one ten thousandth of the diameter of a water droplet, but about 700 times larger than the size of water vapor molecules. Liquid water cannot enter, and sweat The breath can pass through, thus achieving excellent waterproof and moisture permeability.
It is a high-tech enterprise focusing on the research and development, production and sales of kn95 mask filter membranes. It has a factory area of nearly 8,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States. ;The products we produce are all produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity. Moreover, we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
