Disposable medical masks consist of a mask body and a tension band. The mask body 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 kind of high-efficiency medical mask manufacturer has strong hydrophobicity and air permeability, and can filter small virus-carrying aerosols or harmful dust, but can not effectively filter PM10 and PM2.5. The overall filtering effect is good. Some fine dust, especially less than 2.5 microns Dust can pass through the gauze and enter the respiratory system. In the process of filtering this filter material, a dust-proof mask composed of a filter material activated carbon fiber mat or a non-woven fabric with inhalable dust less than 2.5 microns. The disposable medical mask is designed to prevent air from passing through the gap between the mask and the face without being sucked through the filter. Air is like water, and there is almost no resistance where it flows.
Masks are divided into three-layer masks, non-woven masks, four-layer masks, and activated carbon masks. The three-layer mask is made of two layers of non-woven fabric and filter paper; the three-layer mask is made of two layers of fiber non-woven fabric used for medical and health care. The disposable medical mask manufacturer adds a layer to filter and prevent bacteria up to 99 More than% of the filter melt spray cloth is ultrasonically welded. Workers in a multi-person office environment have a loose and well-ventilated office environment, and they do not need to wear a mask if they are in good health. Masks should be worn in the working environment or in environments where risks cannot be determined. It is generally recommended to wear disposable medical masks.
