Description

Antifog haze gauze mask of low resistance is strained to high filtration

Technical Field

The utility model relates to a gauze mask field specifically is a antifog haze gauze mask of low resistance is strained to high filtration.

Background

The mask is a sanitary article, is generally worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to achieve the purpose of blocking harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, is made of gauze or paper and the like, has a certain filtering effect on the air entering the lung, has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like, and has the dust blocking efficiency standard of blocking fine dust, particularly respiratory dust below 2.5 microns. Because the dust with the particle size can directly enter alveoli, the influence on human health is the largest. The gauze mask adopts the dust blocking principle of mechanical filtration, namely, when dust collides with gauze, large-particle dust is blocked in gauze through layer-by-layer blocking. For some fine dust, especially dust less than 2.5 microns, it will pass through the mesh of the gauze and enter the respiratory system. The dustproof mask consists of a filter material, namely an activated carbon fiber felt pad or non-woven fabric, and respiratory dust smaller than 2.5 microns is isolated and blocked in the process of passing through the filter material, so that the dustproof mask plays a role in filtering air.
