ptfe is called polytetrafluoroethylene, which has excellent chemical stability and can withstand strong acids and alkalis. corrosion, and at the same time has a wide temperature tolerance. Therefore, PTFE nanomembrane has great advantages compared with other filter materials.
The nanomembrane uses unique paste extrusion and biaxial stretching technology to produce fiber diameters below 100nm. The fiber cross-sectional area is only 1% of PP melt-blown fiber. The network structure formed by the staggered arrangement of these nanofibers has a very special Good filtration efficiency is enough to effectively protect against bacteria and viruses, and has the characteristics of high efficiency and low resistance.
The filtration efficiency of ptfe nanomembrane for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks. The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing. In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception (pore size interception method). The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.
The ptfe nanofilm produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some poles with a diameter of 0.1um-0.3um For fine particles, the filtration level can reach H13-U16. In addition, the biaxially stretched film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the company’s production process, and it fully complies with current environmental protection standards.
