With the large-scale outbreak of the coronavirus, one of the issues that everyone is most concerned about now is the issue of mask protection.
So which masks have a protective effect on this new coronavirus? Masks made of PTFE reusable mask filters can provide effective protection.
At present, the widely used mask filter material is melt-blown cloth. The filtration efficiency of melt-blown cloth itself is only 30%. It can reach more than 80% after electret treatment and charging. Therefore, melt-blown cloth masks are disposable. , and there is an aging limit. Washing or storing for too long will cause the charge to disappear and reduce the filtration effect.
PTFE reusable mask filter membrane is made of polytetrafluoroethylene as raw material. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process. , becoming a new type of filter material. The membrane has small pore size (0.05~0.45μm), uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation.
