Polytetrafluoroethylene (PTFE) material has excellent high temperature resistance, alkali resistance, oxidation resistance, hydrophobicity and non-adhesion properties.
It is widely used in air purification, industrial dust removal, pharmaceutical fields, electronic appliances, clothing fields, etc.
The PTFE air filtration membrane is prepared by using a biaxial stretching process. It has a microporous structure with staggered fibers. It has high porosity, small and uniform pore size. Therefore, the PTFE air filtration membrane can obtain better results with lower resistance. High efficiency.
PTFE air filtration membrane materials are produced using imported raw materials, with finer molecular weight, cleaner performance, good filtration performance, strong hydrophobicity, good air permeability and better uniformity. It has a complete set of domestically advanced production lines.
Good filtration performance, strong hydrophobicity and good air permeability.
?The air filtration membrane screening process uses the pressure difference on both sides of the membrane as the driving force and the ultrafiltration membrane as the filter medium. Under a certain pressure, when the raw liquid flows through the membrane surface, the ultrafiltration membrane surface is densely covered with Many tiny micropores only allow water and small molecular substances to pass through and become the permeate. However, substances in the original solution whose volume is larger than the micropore diameter on the membrane surface are trapped on the liquid inlet side of the membrane and become concentrated liquid, thus achieving the purification of the original solution. , separation and concentration purposes.
? There are approximately 6 billion 0.01 micron micropores on the wall of each meter of ultrafiltration membrane wire. The pore size only allows water molecules, beneficial minerals and trace elements in the water to pass through. The smallest bacteria in the world are currently known. The volume is 0.2 microns, so bacteria and colloids, rust, suspended solids, sediment, macromolecular organic matter, etc. that are much larger than bacteria can be intercepted by the ultrafiltration membrane, thus realizing the purification process.
