Winter is often a period of high incidence of smog. Wearing a mask when traveling can have a good protective effect, but not all masks can have a good effect, especially against PM2 .5 filtration, the editor below recommends a ptfe nano mask made of ptfe nano film as the core filter material.
To prevent haze, the filter element is the core. The charge in meltblown nonwovens gradually disappears over time. Moisture from breathing can also cause static charges to dissipate. Therefore, the anti-haze effect of “electrostatic adsorption” is much shorter than you think. The elderly and children should not wear melt-blown non-woven masks. The mask is made of multiple layers of non-woven fabrics. The air resistance is very high, which can easily cause difficulty in breathing and even damage the respiratory tract.
ptfe nano filmThe mask material has good water-repellent properties. Its characteristic is that the human body’s sweat can be emitted outwards, while Outside water and small bacteria and viruses cannot enter. There are about 1 billion pores per square centimeter, with a porosity of more than 90%. The pore diameter is about 0.2 μm, which is one ten thousandth of the diameter of a water droplet, but about 700 times larger than the size of water vapor molecules. Liquid water cannot enter, and sweat Air can pass through, thus achieving excellent hydrophobic and moisture permeability. The current mainstream melt-blown non-woven masks have respiratory resistance as high as 70-85Pa. PTFE nano film masks are only 35-40Pa, which is only half of them. Which one breathes easier is self-evident.
It is the manufacturer of ptfe nano film. This material has small fiber diameter, high dust blocking efficiency, and relies on physical effects to It intercepts particulate matter and can be stored for a long time without affecting the filtration efficiency. The filtration efficiency can reach more than 99.5%. And the mask can be reused through simple high-temperature cooking or alcohol spraying.
