Due to the continuous development of industrial processes, the continuous improvement of people’s living standards, and the continuous improvement of environmental awareness and requirements, my country’s filter element market has also gradually developed and improved.
Many new filter materials (especially air filtration, water filtration, etc.) are emerging in endlessly, and ptfe high-temperature membrane is a product of the new era.
At present, my country’s electrostatic precipitator technology has reached a mature stage of application, and bag type dust removal technology is in a period of rapid development. However, as the country continues to increase its requirements for industrial flue gas pollution control, electrostatic precipitator technology can no longer fully meet the requirements. Bag type dust removal technology is used Dust removal technology and electric bag composite dust removal have become mainstream instead of electric dust removal technology.
PTFE high-temperature membrane is made of polytetrafluoroethylene as raw material. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process and can become A new type of filter material, the membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation.
PTFE high-temperature membrane is prepared using unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
It can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and super high efficiency air filters.
