PTFE mask film can prevent dust and bacteria, but cotton masks cannot! The main function of cotton masks is to protect against cold and warmth, and to prevent cold air from directly irritating the respiratory t…

The filter element of equipment such as air purifiers is made of PTFE air filter membrane, which has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, …

Membrane filtration seems to be very fashionable in the domestic fresh milk product market today. As for the application of membrane filtration, it is nothing more than using porous materials to allow substance…

PTFE air 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 proces…

With the vigorous development of my country’s medical industry, drugs have always been indispensable, and filter materials are used in the production process of drugs. PTFE bubble point membrane produced …

1. The surface morphology of ptfe bubble point membrane has a spider web-like microporous structure. Pores are formed between the microfibers, and the arrangement direction of the microfibers is basically paral…

Yes, if the material only passes through the gas but not the liquid, the idea is to have a microporous material that is larger than the gas molecules and smaller than the smallest droplet diameter. The most com…

The respiratory impedance of polytetrafluoroethylene mask membrane is only 60-70pa, and the ordinary melt-blown non-woven mask is as high as 120-250pa. In comparison, the breathability of film masks is already …

The pore size of the polytetrafluoroethylene mask membrane is smaller than the diameter of dust and haze (pm2.5) and a thousand times larger than air molecules, so dust and haze (pm2.5) cannot enter the mask . …
