As personal protective equipment, Gas mask can provide effective protection for respiratory organs, eyes and facial skin of personnel. How can Gas mask prevent gas

The Gas mask can be divided into two parts: the mask and the canister. Through these two aspects, the Gas mask can provide better and useful gas protection.

The mask of the Gas mask uses the principle of a gas pump to form a sealed environment. There is a nose and mouth mask inside the mask. The nose and mouth mask is equipped with an inhalation valve plate to control the entry of gas. The lower part of the mask is equipped with an exhalation valve plate. The exhaled gas can be discharged from the exhalation valve plate, but cannot enter the mask. In this way, the one-way movement of gas is completed through the manipulation of the inhalation valve plate and the exhalation valve plate. When the entire Gas mask is used, The external gas enters the mask through the gas filter tank, and then enters the inlet nose mask through the suction valve plate for breathing. The exhaled gas is discharged from the mask through the exhaust valve. In this way, the Gas mask of the gas filter tank plays an anti gas role.

The internal structure of the canister is sequentially composed of a melt blown cloth layer, an activated carbon layer, a chemical agent layer, and a melt blown cloth layer from top to bottom. The melt blown cloth layer can filter 3 microns of fine dust, achieving a dustproof effect; The activated carbon layer is the theme that plays a filtering role. After adsorption, the activated carbon can absorb toxic gases, which are then differentiated and purified by the chemical agent layer. This is the anti poison principle of the filter tank. The canister is made of 1.5mm coal based columnar activated carbon, which is not easily crushed under pressure and has well-developed pore structure, allowing for maximum absorption of toxic gases.
