Common types of fire goggle range

    ① ordinary optical glass mirrors. By ordinary optical glass lenses, prevention turner, grinders , milling , drilling work , boring work , riveter, sand workers, workers of mechanical damage modeling and acid-base operation , testing, sampling acid burns , the driver anti- foreign objects into the eyes .
    ② UV mirror. In the optical glass melt into the UV-absorbing chemicals, for visible light , ultraviolet absorption rate . Depending on the type of work required lenses are mounted on the frame , mask or helmet. Welding is now made ​​of mirror LCD , glare can be met at the moment 0.001 ~ 0.002s black, protective welding operator electric ophthalmia does not occur.
    ③ HENGDA fire goggle . By the high temperature glass lens can absorb some infrared, smelting operations for blast furnace workers , fireman , blacksmith , watching fire workers, founder , glaziers and so on.
    ④ radiation goggles . In the optical glass is added to the lead for Χ rays , γ -rays , α -rays , β -rays workers .
    ⑤ microwave goggles . The outer surface of the optical glass with a thin layer of metal powder, stannous oxide , for microwave operation.
    ⑥ anti- laser mirrors. Shape for the goggles type, multi-use synthetic polymer lens material, can be replaced. According to the principle of anti- laser radiation , anti- laser glasses into reflective, absorption , reflection absorption -type explosion -type , photochemical reaction type and color glass-ceramic type.
    Note the use of protective eyewear
    Multi- material protective glasses made ​​of glass , should be taken to avoid collision fragmentation. High-speed operation in the event of splashes , the lens may be broken , and damage to the eyes, to take preventive measures, such as the lens plus a layer of metal mesh . At the same time frame to prevent damage to the lens by grinding into the box when not in use . Lead ions within the anti- ray lenses , easily oxidized white, affecting light transmission, should be replaced. The anti- laser glasses were marked by anti- wavelength optical density values ​​and not misused .
