1. Can protective glasses against sunlight and ultraviolet rays be used for welding protection?
may not. Although anti ultraviolet protective glasses can protect 99% or even higher ultraviolet rays in sunlight, they only protect UVA and UVB in ultraviolet rays. In addition to UVA and UVB, infrared IR and visible light with very high intensity, general anti ultraviolet goggles do not have the protection function against these harmful lights and can not play a protective role.
2. In places with metal fragments splashing, do you still need to wear impact glasses after wearing a full mask?
The face mirror of the full mask itself is an impact proof face mirror, and no additional eye and face protection is required.
3. Do protective glasses and respiratory protective articles cause interference and reduce the protective performance?
Generally, the protective glasses will not interfere with the half mask, but can not be used together with the full mask. For the respirator mask with loose fit, the protective glasses can be worn in the mask or hood.
4. Can all dyed glasses be used to protect against ultraviolet rays in sunlight?
no If there is no anti ultraviolet coating, only dyed protective glasses can not block ultraviolet rays. Because the dyed glasses reduce the light intensity and the wearer's pupil enlarges, it will increase the exposure level of ultraviolet radiation and be more vulnerable to injury.
5. What are the characteristics and applicable environment of PC film for protective glasses?
PC protective lens has excellent impact resistance, super wear resistance and limited chemical protection. It is suitable for welding, grinding and other work. It can provide limited protection against spark splash. It is also suitable for a certain chemical environment, provided that it is under the condition of composite seal. It is also suitable for working environment with strong mechanical strength.
6. Is the reflective coating of protective glasses a required function?
There are no clear standards and regulations that require reflective coating is essential. Whether it is needed or not mainly depends on whether it is helpful to the staff. It is recommended to select reflective light coated glasses for industries requiring accurate vision. Such as laboratory, computer monitoring and display operation. The mutual contact of light produces reflection on each mirror, and the reflective coating can reduce these reflected light.
