The difference between traditional masks and nano microporous filter film protective masks
At present, the main material that traditional masks can play a role in virus protection is melt-blown non-woven fabric, an ultra-fine electrostatic fiber cloth that can capture dust. When the droplets containing pneumonia virus are close to the melt-blown non-woven fabric, they will be electrostatically adsorbed on the surface of the non-woven fabric and cannot penetrate.
However, the electrostatic adsorption masks have a huge disadvantage: after static electricity is added, they are not always in a saturated state. From the production, packaging, shipping, transportation of masks, to the hands of consumers, until opening and use, every link will make The static electricity content in the non-woven fabric layer gradually decreases, and the attenuation of static electricity inevitably leads to a decrease in the protective performance of the melt-blown non-woven fabric mask.
As the wearing time increases, due to the wearer's breathing and other human activities, the mask is damp, its electrostatic adsorption capacity is weakened, and the isolation effect is gradually deteriorated. In view of the tiny size of the virus, it is impossible to achieve long-term effective isolation and protection.
The filter layer of the microporous filter-film protective mask is a new type of nanofiber film, which uses physical principles to filter particulates in the air, which can be washed and disinfected, and is truly efficient, comfortable, and reusable.
