The epidemic is not over, and our protection work cannot be stopped. A medical mask is a protective item that must be brought in public during the current epidemic. A piece of cloth, how much do you know about it?
The medical mask is composed of a mask face and a tension band. The face of the mask is divided into three layers: inner, middle and outer. The inner layer is made of skin-friendly material, the middle layer is the isolation filter layer, and the outer layer is a special material antibacterial layer. This high-efficiency medical mask has strong hydrophobic and air permeability, and has a significant filtering effect on microscopic virus-carrying aerosols or harmful dust, but cannot effectively filter PM10 and PM2.5. The overall filtering effect is good, and the materials used are non-toxic, harmless and comfortable to wear.
Features: light, comfortable, odorless, glass fiber-free, non-irritating to the skin, waterproof. The soft and comfortable adjustable nose clip has low breathing resistance and is hygienic to wear. It absorbs aerosols, dust, smoke, mist, poisonous gases and poisonous vapors through the filter material, blocking them from being inhaled.
There are many types of medical masks. Common medical masks are disposable non-woven masks, gauze masks, and special antiviral masks.
Disposable non-woven masks have more than three layers to isolate bacteria and dust, and they are safe and reliable for one-time use without the risk of secondary infection. Gauze masks are the most commonly used type of masks, and gauze masks are widely used in the fields of medical care and scientific research. Anti-virus masks are mainly made of special materials with a filter layer in the middle. Generally, the filter layer is made of activated carbon felt or melt blown cloth. It has the effect of sterilization and sterilization.
We cannot choose masks blindly. Only the right masks can be used for protection.
