PTFE bubble point membrane composite material is a new type of material formed by compounding a layer of polytetrafluoroethylene (PTFE) film on the surface of ordinary filter materials. Currently, this material has a wide range of applications.
Ultrafiltration can intercept particles and impurities between 0.005~0.1μm. The ultrafiltration membrane allows small molecular substances and dissolved solids (inorganic salts) to pass through, but will effectively block colloids, proteins, microorganisms and macromolecular organic matter. , the cutting molecular weight used to characterize ultrafiltration membranes is generally between 1,000 and 500,000, and the operating pressure on both sides of the ultrafiltration membrane is generally 0.2 to 7bar.
PTFE bubble point film composite material has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter and the pore size range is 0.1μm-0.5μm. This film is coated on the It can be used as a new type of filter material on various fabrics and substrates. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve advanced purification and ventilation. Purpose.
The ptfe bubble point film composite materials produced by the manufacturer use imported raw materials, have a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe film; Production and testing instruments imported from the United States are used to test the quality of the PTFE film, and it has passed international SGS testing and certification, as well as ISI testing and certification.
