The filtration mechanism of ptfe nano mask cloth is purely physical filtration. The long-term storage efficiency will not be reduced, and it is safe and reliable. In addition, the filtration efficiency will not be reduced after boiling water cooking and alcohol disinfection and sterilization, and it can be reused.
The electret treatment machine is a treatment equipment specially designed to improve the filtration efficiency of melt-blown non-woven filter materials. It consists of three parts: generator host, step-up transformer and electret treatment rack.
The processor can be combined in the melt-blown production line for online processing or the finished melt-blown filter material can be processed independently. After high-pressure treatment by the processor, the filtration efficiency of the material can be greatly improved.
The respiratory impedance of ptfe nano mask cloth is only 60-70pa, while ordinary melt-blown non-woven masks are as high as 120-250pa. In comparison, the breathability of film masks is already very good, but it certainly cannot be compared with not wearing a mask.
The comfort level of wearing a mask is mainly determined by the breathability and moisture permeability of the mask.
With its material characteristics of high uniform distribution of holes, film masks have higher air permeability and can give users a more comfortable breathing experience.
PTFE nano mask cloth is prepared using unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
