In 2020, due to the impact of the COVID-19 epidemic, the demand for masks continues to increase, which leads to a very shortage of melt-blown cloth, one of the raw materials required for the production of masks. Since the supply of melt-blown cloth is so tight, So can other kn95 mask filter membranes with filtering effects be used to alleviate the problem? Medical masks and protective masks are non-woven materials, composed of directional or random fibers. They are generally multi-layer structures, mainly composed of three layers, usually referred to as SMS structures (S means spunbond layer, M means melt-blown layer) .
At present, the highest number of layers in China is 5 layers, that is, SMMMS, and the KN95 mask with a very high level of protection is 5 layers, 2 layers of melt-blown cloth + 2 layers of non-woven fabric + 1 layer of hot air cotton, which can filter more than More than 95% of fine particles.
Similar to ordinary medical masks, nano antibacterial masks also include an outer layer, a middle layer, an inner layer, ear hooks, nose clips and other parts.
The special thing about nano masks is that the middle layer is made of a nano membrane with a smaller pore size (100-200 nanometers), which is the kn95 mask filter membrane, with a porosity of more than 85% and 1.4 billion micropores per square centimeter. Aperture range 0.02um-1.5um.
It is a high-tech enterprise specializing in the research and development, production and sales of kn95 mask filter membranes. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we produce The products are produced using imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
