Types of protective glasses
①Ordinary optical glass mirror. The lenses are made of ordinary optical glass to prevent mechanical damage of turners, millers, millers, drillers, boring workers, riveters, sand cleaners, and sculptors, as well as acid and alkali burns from acid and alkali operations, tests, and sampling. Drivers Prevent foreign objects from entering the eyes.
②Anti-ultraviolet mirror. Chemicals that absorb ultraviolet rays are melted into the optical glass, which has a high absorption rate of visible rays and ultraviolet rays. According to the needs of different types of work, the lenses are respectively installed on the frame, mask or helmet. There are welding mirrors made of liquid crystal, which can instantly turn black in 0.001~0.002s when exposed to strong light, so as to protect welding operators from electro-optic ophthalmia.
③High temperature resistant protective glasses. The lens is made of high temperature resistant glass, which can absorb some infrared rays, and is used for furnace workers, furnace workers, blacksmiths, fire watchers, casters, glass workers, etc. in smelting operations.
④Radiation protective glasses. Lead is added to optical glass for x-ray, gamma, ray, and beta ray workers.
⑤Microwave protective glasses. A thin layer of tin oxide metal powder is added to the outer surface of the optical glass for microwave operation.
⑥ Anti-laser mirror. The shape is goggles, and the lenses are mostly made of polymer synthetic materials, which can be replaced. According to the principle of anti-laser radiation, anti-laser glasses are divided into reflection type, absorption type, reflection absorption type, explosive type, photochemical reaction type and color-changing glass ceramic type.
