silicone mask is a kind of gas and fog mask developed in the early years. The silicone mask has a long service life, is soft and comfortable, and is not easy to cause allergic reaction when worn for a long time. However, silicone materials are also divided into different degrees of hard and soft hard. High hardness masks are easy to produce indentation, while low hardness masks may not be firm and easy to leak.
It is understood that the market is now called anti fog silicone mask, silica gel mask products, in fact, is only pasted on the face of silica gel material made of parts, the main part is material or Plastic, through the filter core or filter air filtration. Because silicone products have good skin affinity, non-toxic, tasteless, soft and comfortable, not aging, hard, easy to clean, durable, no deformation and other advantages, repeated use can still ensure good adhesion, sealing, etc.
However, if the filter part of silicone mask and ordinary mask can not achieve multi-layer filtration at the same time, filter cotton is still used, such as synthetic fiber filter cotton, non-woven cloth filter cotton, glass fiber filter cotton, activated carbon filter cloth cotton, etc. The novel coronavirus is used to filter the air through one to several kinds of filter cotton and filter with a layer of filter cotton. The actual effect is quite different. Therefore, whether the silicone mask or the ordinary mask, the most important problem is the problem of the intermediate filter element.
At present, most of the silicone masks are mainly made of filter materials, filter channels, exhaust valves, silicone face seals and silicone materials to prevent the leakage of harmful gases into the masks. "After special design, the filter channel of transverse filter cavity is extended, and that of PM2 is extended. 5. Effectively filter dust, choose silica mask, reduce the harm of air to human body. Silicone mask can be used repeatedly and has a long service life. Just replace the filter cotton in the middle part. It is different from ordinary facial mask in the use of food grade environment-friendly silicone rubber and nipple, children's gum material is similar, soft and comfortable, no harm to the skin. And after use of silicone parts can be removed, cooking and disinfection, repeated use, contact with the skin surface does not need to worry about the growth of bacteria!
