The diameter of water molecules is 0.0004 microns, the smallest diameter mist in rainwater is 20 microns, and the diameter of drizzle is as high as 400 microns. If a film with a pore diameter between water vapor and rainwater can be made, it can be achieved Waterproof and breathable.
PTFE nano mask filter membrane can perfectly meet the above conditions.
Currently, the filter layer used for masks is mainly polypropylene (PP) melt-blown non-woven fabric, which is composed of fibers accumulated to form a network-like through-structure, so it has good filtering properties, barrier properties, heat preservation and adsorption properties.
The size of PP melt-blown non-woven fibers on the market is 1-10μm, which cannot reach the nanometer level. The pores formed by fiber accumulation are large and cannot effectively collect small particles. The filtration efficiency of 0.3μm particles is in Below 50%.
The ptfe nanomask filter membrane is used as the protective layer. The fiber diameter is only tens of nanometers (90 nanometers for the new coronavirus). It directly uses the principle of physical isolation to hard-core filter viruses and has excellent filtration performance (filtration efficiency reaches more than 99%). rest assured.
And it can be worn all day long, and its filtration performance is not affected by moisture, sweat, humid weather, etc.
And reusable.
After rinsing with hot water for 15 times, the filtration effect has not declined.
It is a ptfe nano mask filter membrane manufacturer integrating production, sales and customization.
The company has advanced ptfe film production lines and composite production lines.
The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
