Detailed classification and use of protective face shield masks
Protective mask is used to shield the face, protect the face and neck from incoming metal debris, harmful gas spray, molten metal and high temperature solvent droplets.
The protective mask is divided into anti-attack mask, anti-radiation surface force, anti-chemical liquid splash mask, anti-smoke gas surface and heat insulation mask, etc.
Anti - attack mask is used for car, milling, planing, grinding, drilling and other operations.The ear is made of transparent plexiglass, plastic or metal mesh, which can prevent metal chips, sand and other high speed dust particles from hitting the face.
Radiation mask is suitable for various welding operations.The mask is made of thick steel paperboard, which is tough and light, with good insulation and heat resistance.There is an observation hole in the mask, and the light-blocking goggles are embedded.In order to facilitate the operation, there are two kinds of masks: head-mounted and hand-held, and two kinds of fixed and flipped viewing holes.
The chemical splash mask is mainly used to prevent acid and other liquids from harming the face. Most of it is made of plexiglass.
Anti-smoke gas surface force is suitable for the operation of small gas, such as anti-asphalt smoke mask, helmet face shield made of artificial leather, plexiglass observation hole and filter channel that can be changed to prevent the face dermatitis and laryngitis caused by ten contact asphalt dust.
Heat shield is suitable for fire protection, metallurgy, glass, ceramics and heat treatment.The heat shield is composed of aluminum foil heat insulation cloth and glass helmet, which has a good reflection effect on radiant heat, soft texture, waterproof and aging resistance.
