The pore size of the ptfe air filter membrane is small and the distribution is concentrated, which can better prevent fine dust from entering the filter material, just like a first layer of artificial dust, achieving surface filtration (accumulated dust can be easily removed by mechanical vibration or wiping) ) makes the dust removal efficiency reach 99.9%~99.999%, and even has high dust removal efficiency for fine particles of PM2.5~PM10. Therefore, the ptfe coated filter material can achieve a level close to “zero emission” and can meet the sub-high efficiency , filtration efficiency grade requirements for high-efficiency and ultra-high-efficiency air filters.
The filtration efficiency of conventional filter materials is very low. As the filtration wind speed increases, the filtration efficiency of PTFE air filter membrane increases, while the efficiency of conventional filter materials decreases at high filtration wind speeds. This is mainly because Because the particle penetration rate of conventional filter materials increases under high wind speeds; and the removal efficiency of dust particles below 1 μm, especially 0.2~0.4 μm is low, the emission concentration is still high, with the concentration range being 40~80mg/ between m3.
The current emission standard in our country is 50mg/m3. Obviously, using traditional filter materials cannot meet the emission requirements! In summary, the filtration efficiency of ptfe air filter membrane is significantly higher than that of conventional filter materials.
