Principle of PTFE composite membrane filtration
The English abbreviation of polytetrafluoroethylene is ptfe, also called Teflon. This material is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all solvents and is resistant to high temperatures. Therefore, people often combine ptfe with other materials to obtainpolymer PTFE composite membrane.
The magic of PTFE nanocomposite membrane is that it purely relies on physical principles to intercept particles and bacteria, there is no need to add electret masterbatch, no need to go through complicated processes such as loading electrostatic charges, and there is no need to consider the timeliness of the PTFE nanocomposite membrane. Once this kind of mask filter material is applied, it has become the focus of mask manufacturers.
Polytetrafluoroethylene composite membrane has a microporous structure with staggered fibers and a porosity of 80% to 90%. After high-temperature heat setting treatment, the microporous structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform. It has a surface filtration mechanism for easy dust removal. It has strong hydrophobicity and low surface energy. It has good non-adhesive ability and can effectively remove dust from the surface. The accumulated dust can be restored by washing with water or backflushing, greatly extending the service life, and the filtration efficiency can reach 99.999995%.
The polytetrafluoroethylene composite membrane produced by the manufacturer uses imported raw materials and has a full set of advanced production equipment. It has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membranes; it uses production testing instruments imported from the United States to test the quality of PTFE membranes, and has passed international SGS testing and certification, as well as ISI testing and certification.
