The return of smog tells us that for people living in big cities, it is a long-term project to completely solve the smog problem. At this stage, we can only prevent smog from entering the respiratory tract.
Therefore, PTFE mask film is necessary.
A mask must be the right size and worn correctly for the mask to be effective.
The masks sold on the market are generally divided into two types: rectangular and cup-shaped.
Rectangular masks must have at least three layers of paper structure to have a protective effect.
Users should press the wire on the mask to the bridge of the nose, and then spread the entire mask along the bridge of the nose to achieve its effectiveness.
Children can be allowed to wear a rectangular surgical mask because it has no fixed shape and can fit snugly around the child’s face if tied well.
Cup-shaped masks must ensure that the density of the polytetrafluoroethylene mask membrane is sufficient after being attached to the face, so that the exhaled air will not leak out to be effective.
When wearing a cup-shaped mask, you can cover the mask with both hands and try to blow air to check whether there is air leaking from the edge of the mask. If the mask is not tightly closed, readjust the position before wearing it again.
The polytetrafluoroethylene mask membrane made by the Suzhou PTFE filter membrane manufacturer by mechanically stretching PTFE material 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.
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.
