Problems solved by technology

[0004] However, vacuum coating has several disadvantages: 1. The vacuum coating process is relatively complicated, often requiring more than a dozen or even dozens of layers of film, which requires high technical requirements, resulting in high production costs; 2. Coating equipment is expensive and energy consumption is high. It also pollutes the environment when processing the coating, which is not conducive to energy saving, emission reduction and environmental protection; 3. The coating on the glass surface will age with time until it loses its protective effect, and it is difficult to improve the oxidation resistance and anti-friction ability of the coating

Abstract

The invention relates to ultraviolet ray and infrared ray adsorption blue transparent glass, which is formed by that Fe2O3 and CeO2 are added in dry SiO2 and other auxiliary materials, and then the glass is directly fired under the high-temperature melting and low-temperature annealing processes, and the glass is blue and transparent; Visible light transmittance of the glass with 2mm is more than 70 percent, the transmittance of the ultraviolet rays with 200nm-390nm can be reduced to 10-7, the transmittance of the infrared rays with 780nm-1300nm is reduced to 10-6, and the transmittance of the infrared rays with 1300nm-2000nm is reduced to 10-5. The ultraviolet ray and infrared ray adsorption blue transparent glass has low cost, can completely achieve the technical data of vacuum coated glass with Europe and America technology, which is applied to eyesight protection glass products, and can thoroughly overcome the low oxidation resistance, ageing resistance and friction resistance of the vacuum coated glass and is mainly applied to the eyesight protection glass products such as arc welding mask lens, spectacle lens, computer screens, television screens and the like.

Description

technical field [0001] The invention belongs to the field of glass production, and in particular relates to a blue transparent glass that absorbs ultraviolet rays and infrared rays. Background technique [0002] For glass products used in vision protection, for 2mm thick glass, it is required to have a visible light transmittance of more than 70%, and a UV transmittance of 200nm-390nm is required to be as low as 10 -7 , 780nm-1300nm infrared transmittance as low as 10 -6 , 1300nm-2000nm infrared transmittance as low as 10 -5 . [0003] In the prior art, glass products for eyesight protection are mainly vacuum-coated glass of European and American technology. Vacuum coating has been developed to hard film technology, and coating the glass surface with hard film can prevent scratches. [0004] However, vacuum coating has several disadvantages: 1. The vacuum coating process is relatively complicated, often requiring more than a dozen or even dozens of layers of film, which r...
