Protective glasses types and uses

    Protective eyewear is a special role to play in the glasses , using the different needs of different occasions glasses . Such as hospital surgical glasses , welding glasses when using welding , laser engraving laser protective glasses, and so on. Protective glasses , also known as labor glasses, safety glasses and protective mask is divided into two categories, the main role is to protect the eyes and face from UV , infrared and microwave electromagnetic radiation , dust , soot, metals and gravel debris and chemical solutions sputtering damage.
First, the types of safety glasses and use:
1 pieces are solid proof protective glasses, mainly for defense and other metal debris or gravel mechanical damage to the eyes . Glasses and eyeglass frames should be rugged , anti- shock. Cover fitted around the edge of the frame , on which there should be vents. Protective lenses can be used tempered glass, glass or copper mesh glial adhesion HENGDA fire goggle .
2 anti-chemical solution protective glasses, mainly for defense irritation or solution corrosive chemical damage to the eyes . Can use an ordinary plain lenses , frames should be covered to prevent splashing into the solution . Typically used in laboratories , hospitals and other places , the general medical glasses GM.
3 . Radiation protection glasses, too strong for defensive ultraviolet radiation damage to the eye. Lenses using radiation can be reflected or absorbed , but it can be made visible through a special glass. Lens bright chromium plated , nickel , mercury or silver metal thin film numbers , may reflect radiation ; blue lenses absorb infrared , yellow lenses absorb ultraviolet and infrared, colorless lenses absorb X -rays and lead γ rays. For example, common welding glasses, the lens transmittance requirements are relatively low, so the lens color ink mostly dominated ; laser protective eyewear , by definition, can prevent the laser radiation on the glasses , so the lens is demanding, such as for select the decay rate of the light source , the light reaction time, optical density , light effects, different nanometer (nm) laser wavelength requires different lenses .
Second, protective masks are the following :
1 anti- bodies late cuttings and chemical solution splashed into eyes and damage to facial HENGDA fire hood , plastic overlay on both sides and the lower production of transparent plastic with a lightweight , multi-use polycarbonate , respectively, under the ears and toward the lower amount of neck extension , so that the mask can be more fully coated face to enhance the protective effect.
2 heat addition heat protective clothing mask mentioned foil mask , the metal can also be single or double mesh made ​​, but double as well, part of the radiation is blocked and can heat the air. As can be chrome or nickel , can enhance the effect of heat reflection , and to prevent rust .
3 metal mesh mask can also be anti-microwave radiation.
4 welders mask , with a thickness of cardboard fiber, light , heat , and has good electrical insulating mask.

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 .

Protective effect of protective glasses and protective mask

    Protective glasses and protective eye and face protective masks mainly from ultraviolet , infrared and microwave electromagnetic radiation , dust , soot, metals and chemical solutions sputtering gravel and debris damage .
    ( 1 ) protective glasses commonly made ​​of flexible plastic and rubber , box large enough to cover the user's eyes .
    Anti solid debris protective glasses, mainly for defense and other metal debris or gravel mechanical damage to the eyes . Glasses and eyeglass frames should be rugged , anti- shock. Cover fitted around the edge of the frame , on which there should be vents. Protective lenses can be used tempered glass, glass or copper mesh glial adhesion goggles .
    Anti- chemical solution HENGDA fire goggles, mainly for defense irritation or solution corrosive chemical damage to the eyes . Can use an ordinary plain lenses , frames should be covered to prevent splashing into the solution .
    Radiation protection glasses, too strong for defensive ultraviolet radiation damage to the eye. Lenses using radiation can be reflected or absorbed , but it can be made visible through a special glass. Lens bright chromium plated , nickel , mercury or silver metal thin film can be reflected radiation ; infrared absorbing blue lens , green lens absorb ultraviolet and infrared, colorless lenses absorb lead X -rays and γ -rays .
    ( 2 ) HENGDA flash hood are the following :
    The end of the anti- bodies and debris chemical solution splashed into eyes and face mask facial injuries , plastics, and the lower sides with a light overlay of transparent plastic production , the use of polycarbonate were under the ears and neck extending toward the lower amount , so that the mask more fully coated face to enhance the protective effect.
    Heat addition heat protective clothing mask mentioned foil mask , the metal can also be single or double mesh made ​​, but the bilayer as well, part of the radiation is blocked and can heat the air. As can be chrome or nickel , can enhance the effect of heat reflection , and to prevent rust .
    Metal mesh mask can also be anti-microwave radiation.
    Welders mask , with a thickness of cardboard fiber, light , heat , and has good electrical insulating mask.

Regular fire blanket in the home

Fire blanket is mainly used in enterprises, shopping malls, ship, automobile, civil buildings and other places of a simple initial fire fighting tool. Especially suitable for the family and the restaurant's kitchen, hotel, entertainment, gas stations and other places of some burns easily. To prevent fire spread and protection to escape.

At the beginning of the fire, the fire blankets directly covered the fire, the fire can be extinguished in a short time.

Fire helmet use cleaning and maintenance and the note

When on fire helmet hat shell is clean, use soap and water and soft cloth to clean. Don't recommend the use of grinding sand mold cleaning sponge surface screen and safety goggles, recommend the use of fire helmet supplier sea on offer professional detergent and soft cloth to clean, ensure the cleaning of the surface screen without damage. When clean cap lining, the cap can be lined with about 30 degrees Celsius temperature with mild detergent to clean warm water. As far as possible using tap water rinse cap inside the shell. Note: do not use hydrocarbon cleaning products or solvent cleaning and fire helmet surface screen and goggles.

After cleaning the fire helmets you need for each part, especially all the link of a thorough examination. Mainly check the correct part fixed way fixed parts, secondly whether there is a visible wear parts, helmet whether any damage. Ensure the normal regulation of the fire helmet. If there are parts damaged parts, it is only through the helmets are accredited suppliers to buy parts for installation, in order to ensure that the helmet in conformity with the specifications. Recommendations on a regular basis to qualified institutions to test whether a helmet to use standard.

If fire helmet clean up is completed, you can put on the helmet specific protection bag, or seal, such as closet, cabinets, etc. Storage place as far as possible away from humidity, illumination and exhaust gas. Avoid falling when stored in or knock against, because it may lead to damage of mask, helmet weaken shock absorption system function or damage to the surface protection coating.

Fire helmet use notice:

The helmet is not suitable for long time use.

Safety goggles when have scratches or damage should be replaced.

When carrying a helmet, mask and safety goggles should be stored in the helmet.

If sensitive physique, when material in contact with the skin, can cause allergic reactions.

After each use of the fire helmet, to make a thorough clean.

Fire blankets

fire blankets through special processing of glass fibers 12 hs satin fabric, tight structure and high temperature resistance, can well protect the object from the heat and spark zone, and prevent or isolation of combustion. Fire blanket thickness of only 1.0 mm, resistance to high temperature of 550 degrees, frame structure and can be used in the shipbuilding industry to the ship repair; Can also be used in the petroleum chemical industry enterprise in metal structure welding, heat insulation, insulation and need showed good protective adaptability.
