Epidemic prevention and control has become normalized, and masks have become standard equipment in daily life. However, corresponding “mask questions” have also arisen, such as when to take off and when to wear masks, how to store masks, especially whether disposable masks can be replaced by kn95 mask filter film, etc.
When the price of melt-blown cloth, the core filter material of ordinary protective masks, soars and the supply is tight, polytetrafluoroethylene microporous membrane composite Protective masks made of fabric stand out. The melt-blown material of ordinary protective masks intercepts harmful substances based on the principle of electrostatic adsorption. As the use time increases or the temperature and humidity change, its filtration efficiency drops significantly.
The mask made of kn95 mask filter membrane is based on the principle of physical barrier, and the filtration efficiency will not change due to moisture or time of use. It decreases as it increases, and the polytetrafluoroethylene microporous membrane is hydrophobic and breathable, and there will be no water vapor retention. It has small breathing resistance and is more comfortable to wear. The main advantage is that it can be reused after treatment. In order to solve the problem during special periods To meet the public’s protection needs and reduce the pressure on the environment caused by a large number of discarded masks. The PTFE microporous membrane has small pore size (0.05~0.45μm), uniform distribution, and large porosity, while maintaining air circulation. Through physical screening, viruses and small bacteria are blocked on the surface of the mask, and with the help of the strong self-lubricating characteristics of the kn95 mask filter membrane, every time you exhale, the adhesion will be reversed The particles on the surface of the mask are pushed back into the environment repeatedly, without relying on electrostatic adsorption, and truly achieve a very good protective effect.
The polytetrafluoroethylene microporous membrane produced by the manufacturer uses imported raw materials and has a full set of advanced production equipment. Interested parties can enterShopContact us.
