Heavy metal welding protection glass

Abstract

The invention relates to a heavy metal electric welding protective lens with uvioresistant and anti-infrared function used on a welding mask, which is prepared by the following material according to parts by weight: 60-80 parts of quartz sand, 6-10 parts of ferric oxide, 1-4 parts of cerium oxide, 0.5-2 parts of cobalt oxide, 8-10 parts of calcined soda, 3-5 parts of calcite, 1-2 parts of nickel oxide and 2-5 parts of manganese powder, and has the advantages of uvioresistant and anti-infrared. The invention can resist the infrared, the ultraviolet radiation and the harmful light, and visible light can be passed, simultaneously, the visible light of a welding object filtered by the lens of the invention can be comfortably observed by welder, the ultraviolet transmittance of the invention is between 313nm to 365nm, and the infrared transmittance is between 780nm to 1300nm or 1300nm to 2000nm, thus conforming with the requirement of national standard.

Description

Technical field: [0001] The invention relates to a heavy metal electric welding protective lens used on an electric welding mask with anti-ultraviolet and infrared functions. Background technique: [0002] The existing welding protective lenses used on welding masks have always used transparent colorless glass as the preferred manufacturing material, which has the defects of low product safety performance, poor high temperature resistance and transmittance performance, and short service life, which brings great difficulties to electric welders. There came a very great bodily injury. Also have to adopt black glass to solve the above-mentioned existing defect, but this black glass exists the defect that is not anti-ultraviolet, infrared ray, can bring very big bodily injury to electric welder equally. Invention content: [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a heavy metal electric welding protective lens wit...

Problems solved by technology

[0002] The existing welding protective lenses used on welding masks have always used transparent colorless glass as the preferred manufacturing material, which has the defects of low product safety performance, poor high temperature resistance and transmittance performance, and short service life, which brings great difficulties to electric welders. very serious bodily harm

There is also the use of black glass to solve the above-mentioned defects, but this kind of black glass has the defect that it is not resistant to ultraviolet rays and infrared rays, and it will also cause great physical harm to welders.
