Supply JY-5002A N95 Mask/Two-Canister Chemical Mask
Relevant information:
Dust-proof masks are individual protective equipment designed to prevent or reduce the inhalation of airborne dust into the respiratory system, thereby protecting life safety.
Mainly used in work environments with low concentrations of harmful gases and vapors. The filter box is only equipped with adsorbents or absorbents. Some filter poison boxes also have a filtering layer, which can simultaneously prevent aerosols. It is mainly made of activated carbon cloth, or it is made of an anti-water anti-oil fabric as the outer layer, glass fiber filtering material as the inner layer, and a polyurethane foam plastic soaked in activated carbon as the bottom layer. It can provide temporary protection when exposed to sudden attacks of poisonous gases or dust.
The selection principle of dust-proof masks:
FirstThe efficiency of a mask to resist dust should be high. The standard for evaluating the efficiency of a mask is its ability to resist fine dust, especially respiratory dust smaller than 5 μm. General gauze masks use a mechanical filtering principle, which means that when dust impacts the gauze, it is blocked by layers of barriers, trapping some larger particles of dust in the gauze. However, fine dust, especially dust smaller than 5 μm, can pass through the mesh of the gauze and enter the respiratory system. Currently, there are some dust-proof masks on the market, with filter materials composed of fibers charged with permanent static electricity. These respiratory dust particles smaller than 5 μm, when passing through this type of filter material, are attracted by the static electricity and adhered to the filter material, effectively preventing dust.
SecondThe fit of the mask to the face shape should be tight. When the mask does not fit the face tightly, dust in the air will enter the respiratory tract through the gaps around the mask. Therefore, people should choose a dust-proof mask suitable for their face shape and wear it correctly.
ThirdWearing comfort is essential, including low breathing resistance, light weight, hygiene, and easy maintenance, such as wearing arched dust masks.
