Abstract

The invention discloses an improved gray glass, which comprises basic glass and a coloring agent. The basic glass components are: 50-70 parts of silicon dioxide; 5-10 parts of magnesite; 1-3 parts of soda ash; 2-5 parts of alumina; 10-12 parts of sodium oxide; 2-8 parts of potassium oxide. The components of the colorant are in parts by weight: 1-3 parts of dichromium trioxide; 0.1-0.3 parts of selenium; 0.1-0.3 parts of nickel; and 0.2-0.5 parts of manganese dioxide. The gray glass of the present invention has low visible light transmittance and low ultraviolet transmittance, which is beneficial to reduce the heat increase in the space, reduce ultraviolet radiation, prevent ultraviolet rays from burning human skin and avoid aging of decorative materials in the space.

Description

technical field [0001] The present invention relates to a gray glass, in particular to an improved gray glass. Background technique [0002] Glass is used more and more widely in the construction industry. The colorants usually used for gray glass are iron, cobalt, selenium, titanium, manganese, etc. Different colorant combinations are selected to generate gray glass with different properties. Therefore, the type of chemical elements added to the colorant directly determines the gray color. properties of the glass, but excessive colorants can have an effect on the texture of the glass itself. [0003] Therefore, it is necessary to provide a new technical solution to solve the above problems. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the present invention provides an improved gray glass. [0005] The technical scheme adopted in the present invention: [0006] An improved gray glass, comprising a base glass and a colorant, the base...
