Biaxially stretched polytetrafluoroethylene filter bag membrane

PTFE filter bag membrane has excellent properties such as low resistance, high interface strength, high stretch and high puncture strength, and can be used in many fields such as industrial dust removal, clothing, vacuum cleaner liquid filtration, and gas filtration. .

The dust layer formed by polytetrafluoroethylene filter bag membrane filtration is easy to crack and corrode, and the filter material has good air permeability. Since the coated filter material relies on a thin film to capture dust particles, the dust layer can only form on the outside of the filter material film. The film is hydrophobic, and the adhesion between the dust layer and the filter material is small, making it easy to split. It can fall off by its own weight without external force.

If the dust is blown back, it can be completely removed. If anti-static PTFE high-temperature film is used, the dust can be stripped off more easily and the dust can be cleaned more thoroughly.

?Can be based on user requirements.

The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
