fire goggles generally used for a variety of welding, cutting, blast furnace workers, microwave, laser defense workers in hazardous radiation hazards. According to the principle of the protective effect of the lens into two categories:
Reflective protective lenses: the reflection of the way, can be divided into interferometric and diffraction pattern.
Absorbent protective lenses: According to the principle of selective absorption of light, with the color of the glass used, for example, infrared radiation exposure should wear green lenses, UV radiation exposure wear dark green lenses, there is an added ferrous oxide lenses more comprehensive absorb radiation.
Composite protective lenses: one or more dyes added to the matrix, and then deposited on the dielectric multilayer reflection film. Because of this the absorbent protective goggles and a reflective mirror goggles combines the advantages, to some extent, improve the protective effect.
Protective mask:
End against solid debris and chemical solution mask: Using lightweight transparent plastic or polycarbonate plastic production, mask the sides and bottom, respectively, to the ears and the lower jaw and neck extended, so that the mask can fully cover the face, enhancing the protective effect .
Heat-resistant mask: In addition to heat protective clothing and aluminum foil aluminum foil mask matching, there are chrome or nickel plated layer made of metal mesh, reflective heat and heat insulation effect good, and can prevent microwave radiation.
Welders mask: production welders protective glasses with dark green glass, cardboard fibers surrounding the future with masks, anti-thermal effect, and has a certain electrical insulation.
