In recent years, with the improvement of my country’s productivity level and the advancement of science and technology, some new products and technologies have been well applied, including polytetrafluoroethylene microporous membranes.
The diameters of the particles found in various gases in nature are very small, for example: fly ash 1~200, pollen 2O~3O, dust O. 1～2O, bacteria 0.3～3, oil fume 0. O3~1, tobacco smoke O. O1~1, virus O. O2～O. O5, radioactive dust 0.003~0.018, radon radioactive particles 0.001~0.04 (unit is m in 1:2).
If plant fiber filter paper is used, the filtration efficiency is (16~87)%, and the best transmittance is 13%.
The filtration efficiency of polytetrafluoroethylene microporous membrane is 99.99995%, and the transmittance is 0.00005%.
In comparison, this means that if a gas containing 1 million dust (particles) is filtered, as many as 1.3 million particles will pass through the former, while only 5 particles will pass through the latter.
It can be seen that the filtration efficiency of ultra-fine glass fiber filter paper is very outstanding.
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 microporous membranes, Teflon films and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
The PTFE filter membrane we made by mechanically stretching PTFE material can ensure the complete retention of bacteria and other impurities, and at the same time have a large flux.
