The filtration principle of Teflon waterproof and breathable membrane is physical barrier, and the filtration effect is not affected by factors such as moisture. It is more suitable for use in summer prone to sweating and humid environments. It can be worn all day long and can be used repeatedly.
Nano materials are actually not new materials. They were born in the United States in the 1980s. Nano filter materials have not yet been recognized by consumers and many mask manufacturers in China; some ignorant users use fire to identify whether the filter material is melt-blown cloth. Containing water, I don’t know where I learned this pseudo-scientific identification method; the national standard requires that the basic indicators for masks to meet the standards are filtration efficiency, exhalation resistance, inhalation resistance, etc. The national standard never requires the use of ignorant methods such as burning or testing for water seepage. In fact, The filtration effect of nanofiltration material is far superior to traditional melt-blown cloth in various indicators.
Teflon waterproof and breathable membrane has the characteristics of high porosity, small pore size, low filtration resistance, and high filtration accuracy. It does not need to add static electricity, intercepts pollutants through screening, and can effectively filter more than 99% of non-oily particles. , effectively intercepts various solid aerosols, droplets and viruses, without worrying about the reduction of liquid filtration efficiency. At the same time, it has good breathability and will not cause breathing discomfort.
The Teflon waterproof and breathable membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely small particles with a diameter of 0.1um-0.3um For particles, the filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
