PTFE microporous membrane meets the requirements of coating various filter materials
With the continuous development of society, people’s requirements for air filtration are gradually increasing, and the continuous improvement of the quality of life is also prompting the upgrading of air filters. Among these air purification equipment, it is indispensable The material is polytetrafluoroethylene microporous membrane.
Conventional filter materials carry dust that is easily adhered to, and the dust does not fall off easily during cleaning, resulting in low dust cleaning efficiency and short-term dust emission.
Because the pore diameter is tens of thousands of times that of water molecules, it is hundreds of times smaller than water droplets.
The polytetrafluoroethylene membrane has high porosity and low filtration resistance, which will not cause too much filtration resistance to the composite filter material.
The polytetrafluoroethylene microporous membrane is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
