Application scope of UNM polytetrafluoroethylene composite membrane

Polytetrafluoroethylene (PTFE) composite membrane is a new material made of a layer of polytetrafluoroethylene (PTFE) film on the surface of ordinary filter material. At present, this material has a wide range of applications.

The dielectric constant of polytetrafluoroethylene is relatively small, so it can be used to prepare enamelled wire for micro motor. In addition, fluoroplastic film has certain selective permeability to various gases, so it can be used to prepare oxygen sensor. In addition, combined with the characteristics of polar charge deviation of fluoroplastics under specific conditions, it can be used to prepare speakers, equipment parts and so on.

PTFE membrane of polytetrafluoroethylene composite membrane has microporous structure with staggered fibers. It is prepared by biaxial stretching process and high-temperature heat setting treatment. The microporous structure of the material is very stable. In the whole production process of stretching microporous membrane, the stretching conditions are very important factors, which will affect all the indexes related to pore performance, such as the thickness, average pore diameter and maximum pore diameter of microporous membrane.

The polytetrafluoroethylene composite membrane produced by youkefa has strong hydrophobicity, chemical resistance, water resistance and low wind resistance, and can obtain high dust removal efficiency. For some very small particles with a diameter of 0.1um-0.3um, the filtration grade can reach h13-u16. In addition, biaxially stretched membrane can undoubtedly achieve ultra-low emission for intercepting all kinds of dust produced in the production process of enterprises, and fully meet the current environmental protection standards.
