In hazy weather, it is really important to take personal safety precautions. For example, wearing a high-quality mask during outdoor activities is the kind of thing that needs to be highlighted in capital letters and bold.
So what kind of masks can truly provide protection? Masks made of polytetrafluoroethylene mask film are very good.
?The English name of polytetrafluoroethylene is ptfe.
The surface of the polytetrafluoroethylene mask membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2.5.
It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is laminated on various fabrics and substrates using a special process. material, it can become a new type of filter material.
? is a high-tech enterprise focusing on the research, development and production of fluorine material membrane technology. It is engaged in technology development, transfer, consulting and services in the field of new materials; R&D, production, sales and customization; and providing design solutions for high-efficiency separation and filtration materials. business.
