The kn95 mask filter membrane is a semi-finished product made of rods and strips extruded from polytetrafluoroethylene and calendered into a film. After being stretched at a temperature below the melting point and heat-set, the resulting porous product is the most popular in the modern industry. A new type of high-tech material.
The mask industry chain includes mask manufacturing, raw materials and production equipment.
Medical masks are generally composed of three layers. The upper and lower sides are made of PP non-woven fabric. The middle layer is generally made of 20-gram melt-blown fabric, which plays the main protective role.
The core of the protection level of medical masks depends on melt-blown cloth. Melt-blown cloth uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. One ton of polypropylene can produce 90-100 disposable medical surgical masks. Ten thousand pieces, and the production of N95 medical protective masks is about 200,000-250,000 pieces.
The kn95 mask filter membrane material can 100% intercept various phages, bacteria and particles above 0.02um.
The pore size of the material is small and the distribution is concentrated. Surface filtration is achieved to achieve a dust removal efficiency of 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.
Can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
