The three-layer and five-layer composite material is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
The polytetrafluoroethylene membrane has a very high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency, and ultra high efficiency air filters.
?At present, there are two methods of compounding three-layer and five-layer composite materials: glue compounding and thermal compounding.
1. Glue composite is a relatively basic composite method with low composite strength, easy to peel off, and short service life. Due to the penetration of glue, it has poor air permeability and is not suitable for cleaning, which weakens the superior performance of PTFE.
?2. Thermal composite advanced composite method completely maintains the superior performance of PTFE film, but has strict requirements for thermal composite technology.
