China Medical Vaccine Refrigerators Wholesalers introduces the barrier principle of masks:

1. Outer layer - waterproof layer: usually needle-punched cotton, also called polyester needle-punched felt, polyester material itself is difficult to absorb water. Droplets are difficult to pass through, while non-polar air can be easily inhaled. In order to improve the effect of the waterproof layer, some masks are covered with fluorocarbon polymers, which further reduces the surface energy of the waterproof layer, thereby improving the waterproof effect.

2. Middle layer - filter layer: The main material of meltblown non-woven fabric is polypropylene, which is an ultra-fine and electrostatically charged fiber cloth that can capture droplets and dust. This layer of non-woven fabric is made up of countless ultra-fine and electrostatic short fibers, which are intertwined and intertwined by mechanical force. Droplets and dust are like a maze in the jungle composed of short fibers. Under the action, most of them stumble and adhere to the dense short fibers, thus playing a strong adsorption effect. It is also the strong adsorption effect of this layer that greatly reduces the risk of infection.

3. Inner layer-comfort layer: It is a hot-rolled non-woven fabric, but the moisture absorption and air permeability are much better than the other two layers, which mainly ensure the moisturizing of the nose and mouth and improve the wearing comfort. After wearing a mask correctly, in order for the "new coronavirus" to infect us through droplets, it needs to pass these three barriers to enter our lungs, which greatly reduces people's risk of infection and disease.
