The principle of gas mask gas

Gas masks are one of the indispensable protective articles in industrial production. They can provide users with comprehensive respiratory protection. What do gas masks rely on for gas protection?

The gas mask can be divided into two parts, a face mask and a poison filter (tox canister, poison filter box). The gas mask mainly filters poisonous and harmful substances through the poison filter. The poison filter is generally composed of a filter layer and an adsorption layer. The adsorption layer can effectively adsorb toxic vapor, and the filter layer can filter out the toxic aerosol.

The adsorption layer generally uses activated carbon loaded with a catalyst or a chemical agent. The toxic gas reacts with the chemical agent to filter out the toxic gas.

The filter layer is generally composed of multiple layers of glass fibers, which can effectively filter out toxic aerosols. Toxic fumes and dust can be called harmful sols. The filter layer composed of glass fibers can effectively block the movement of toxic aerosols Play a filtering role.
