Teflon air filter membrane for indoor pollution control
Many indoor pollutants now mainly include fine particles, gaseous pollutants, microorganisms, bacteria, viruses, etc.
To remove indoor pollutants, air filters with multiple layers and different types of composite membranes are usually used, and the most important function here is the Teflon air filtration membrane.
Polytetrafluoroethylene, the English abbreviation of PTFE, was accidentally discovered by Dr. Plunkett of the United States in 1938.
In 1950, it was officially put into mass production and marketed.
Teflon air filter membrane is a synthetic polymer material polymerized from tetrafluoroethylene monomer. Its molecular structure can be seen as fluorine replacing all the hydrogen atoms in polyethylene.
It is precisely because of the above structure that PTFE has excellent chemical stability and corrosion resistance.
Because the entire polytetrafluoroethylene is electrically neutral in analysis, has a large volume resistance, small dielectric constant and dielectric loss, it can be used in high-temperature electrical environments for a long time and has excellent dielectric properties.
PTFE also has an extremely low surface friction coefficient and excellent mechanical properties.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the R&D, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, PTFE membranes, Teflon air filtration membranes and coated filter materials.
PTFE short fibers can be used to make needle-punched felt for filtration; PTFE woven yarn can be used to make the base scrim of needle-punched felt. Because of its long service life, it can not only be used as PTFE The base fabric of vinyl felt can also be used as the base fabric of felt made of other types of high-performance fibers; polytetrafluoroethylene sewing thread can be used in the manufacture of various types of filters.
