    Gas masks, has gradually been accepted. From the emergence of fog and haze, H7N9 generation, gas masks into people's lives. Today, large to large chemical plants, paint factories, small roadside shop furniture decoration, are accompanied by a gas mask. Gas masks obvious advantage is that many of its high degree of protection relative protective masks, and compared with heavy breathing apparatus, more lightweight.
    The view of human beings continue to research and development, gas masks cartridges (or canisters) has gradually improved, the basic common toxic gases are possible protection, such as painting, hydrogen sulfide, sulfur hexafluoride, methane, ammonia , hydrogen cyanide and the like.
    Gas masks do not understand, there will be doubt, gas masks are not only anti-virus capable of gas, dust and other particles, is not it will not be able to protect it? This is not so. Gas masks also can prevent dust and other harmful particles, only need to install a cotton filter cartridges can be in or on the canister. This combination, the industry is also known as toxic dust respirators combination.
    Gas mask is one of the important components of everyday industrial safety personal protective equipment, respirators can provide a full range of respiratory protection for workers, wear, whether it is in the barn dust or mist generated during painting and other harmful organic chemicals , it can not cause damage to the health of workers.
    That rely on anti-virus masks what is?
    Gas masks primarily to filter the toxic and hazardous substances via cartridges or canisters. The cartridges generally composed of two layers and adsorption filter layer combination.
    Activated carbon adsorption layer is usually made of activated carbon charcoal are specially treated, between its carbon atoms with oxygen has opened the millions of tiny holes. Surface area per gram of activated carbon can reach 300-2000 meters. Activated carbon is widely used to absorb this flavored or colored substance in gas or liquid. When harmful substances by adsorption layer of activated carbon through its own chemical attraction to its adsorption.
But it can only be activated carbon adsorption have good carbon impurity elements, such as the general organic gases. But many do not be activated carbon adsorption of toxic substances, such as sodium nitrate or other toxic and harmful aerosols, so then you need a gas mask cartridges in a filter layer for specific chemical reactions, and toxic gases.
    Aerosol contains: toxic fumes (solid particles), smog (liquid particles), and radioactive dust containing bacteria, viruses, particles and the like.
    Respirator cartridges in a filter layer is not harmful aerosol particles aerosol filtration process and chemical nature of the relationship, mainly related to its physical properties, movement characteristics. Filter layer commonly used are glass fiber filter layer, which consists of many layers of criss-cross grid of fiber, when the aerosol particles through, once exposed to fibers that have been quarantined.
    The chemical industry and other fields of daily painting, body masks substantially identical, the only not the same, is the choice of cartridges or canisters are not the same, you can either provide the necessary protection toxic substances effective option Cartridges gas masks to the manufacturers, the manufacturers have to recommend to you the appropriate cartridges. Whether black market cartridges or canisters, each manufacturer has a different color labels for easy distinction.
