The polytetrafluoroethylene film material has strong hydrophobicity, non-adhesion, corrosion resistance, thermal stability and good mechanical properties. Therefore, it can be washed with water to restore its performance and achieve repeated use, greatly extending its service life and saving costs.
Coupled with special treatment, the polytetrafluoroethylene film has five effects: high efficiency, low resistance, anti-pollution, uniform and stable, inertial sedimentation, random diffusion, electrostatic sedimentation, and gravity sedimentation. It is small, with a diameter of only 0.1-10 μm. Compared with ordinary filter materials, the void diameter is reduced by dozens of times. It is difficult for ordinary dust particles to pass through the micropores.
