The filter material of disposable medical masks is more efficient in blocking.
This is mainly due to the fact that it uses materials with smaller fiber diameters compared to traditional masks.
Generally speaking, the fiber diameter of the ordinary non-woven materials used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE film material is between 100 and 200 nanometers, which is much smaller than the above diameters. , so it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.
The polytetrafluoroethylene microporous membrane is prepared using a unique biaxial stretching technology, which can ensure the complete retention of bacteria and other impurities while having a large flux.
