What are the functions of protective masks and glasses?

Protective glasses and masks mainly protect eyes and face from ultraviolet, infrared and microwave radiation, dust, smoke, metal and gravel debris and chemical solution sputtering

(1) protective glasses are usually made of flexible plastic and rubber, and the frame is wide enough to cover the user’s eyes

protective glasses against solid debris are mainly used to prevent mechanical damage to eyes caused by metal or gravel debris. The lens and frame shall be of strong structure and resistant to impact. The frame is surrounded by a cover, on which there should be ventilation holes. Toughened glass, glued glass or copper wire mesh can be used as protective lenses

protective glasses against chemical solutions are mainly used to protect eyes from chemical damage caused by irritating or corrosive solutions. Ordinary flat lens can be selected, and the frame should be covered to prevent the solution from splashing in

anti radiation protective glasses are used to protect the eyes from excessive ultraviolet radiation. The lens is made of special glass which can reflect or absorb radiation, but can pass through certain visible light. The lens is plated with bright metal film of chromium, nickel, mercury or silver, which can reflect radiation; The blue lens absorbs infrared rays, the yellow green lens absorbs ultraviolet rays and infrared rays at the same time, and the colorless lead lens absorbs X-rays and infrared rays γ Rays< (2) there are mainly the following types of protective masks: the masks used to prevent group debris and chemical solution from splashing into eyes and damaging the face are made of light transparent plastic, mostly polycarbonate and other plastics. The two sides and the lower end of the mask extend to the ears and the lower end of the forehead towards the neck respectively, so that the mask can cover the face more comprehensively and enhance the protective effect in addition to the aluminum foil mask mentioned in the heat proof clothing, the heat proof mask can also be made of single-layer or double-layer metal mesh, but the double-layer is better, which can shield part of the radiation and dissipate heat in the air. 1f it can be plated with chromium or nickel, it can enhance the reflective heat protection and prevent rust the metal mesh mask can also prevent microwave radiation the welder’s mask is made of a certain thickness of hard paper fiber, which is light, heat-resistant and has good electrical insulation our website solemnly declares that this article is reprinted by network media, only representing the author’s point of view, and has nothing to do with our website. 1f the information column articles and comments violate your legal rights, please call to let us know and we will deal with them in time
