An epidemic in 2020 made masks a necessary anti-epidemic material for everyone, and also gave birth to many new products New situations and new applications of technology. As a new type of filter material, kn95 mask filter membrane has gradually entered people’s field of vision.
N95 is the certification level of respirators in the United States, certified by the National Institute for Occupational Safety and Health (NIOSH). This type of mask can filter out more than 95% of non-oily particles (aerosols) under the specified air flow rate (85L/min), so it is named N95. And if it can filter more than 99% of particles (aerosols), it is called an N99 mask. In addition, corresponding to N95, KN95 is a mask certified by my country’s GB2626-2006 respiratory protective equipment self-priming filtering anti-particulate respirator standard.
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 kn95 mask filter membrane manufacturer specializing in R&D, production and sales. The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability. It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
