Problems solved by technology

[0005] Colored glass is a commonly used decorative item nowadays, but due to the different surface stress of curved glass, the light-transmitting surface is also different from flat glass, and color treatment on curved glass will seriously affect the color contrast
Changing the curved glass will reduce the structural strength

Abstract

The invention provides a technology for preparing curved-surface colored glass. The technology includes the following operation steps that 1, an arc mold is manufactured according to the size, the shape and the curvature of the to-be-processed glass; 2, sheet glass is laid on the arc mold; 3, the arc mold in which the sheet glass is clamped is placed into an electric furnace for hot bending; 4, the arc mold obtained after the processing in the third step is taken out and cooled in a natural-ventilation mode; 5, a colored film is placed on the upper surface of the curved-surface glass blank processed in the fourth step, and covered with a curved-surface glass blank with the radian the same as the bottom radian, mold setting is carried out, and the product is fed into the electric furnace and subjected to compounding curing; 6, the curved-surface glass blank obtained in the fifth step is subjected to edge elimination, grinding and polishing. By means of the technology, the curved-surface colored glass is effectively prepared and produced, the structural strength of the curved-surface glass is not influenced, the color contrast formed on a curved surface can be reduced, and further application and popularization can be carried out.

Description

technical field [0001] The invention relates to the field of glass manufacturing and processing, in particular to a process for preparing curved colored glass. Background technique [0002] With the development of industrialization and informatization, people's living consumption level is also constantly improving and upgrading, especially for the living and using environment, more attention is paid to aesthetics and comfort. [0003] Glass is formed by melting silicon dioxide and other chemicals together (the main production materials are: soda ash, limestone, quartz). A silicate-based non-metallic material that forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling to cause it to crystallize. Widely used in buildings, used for wind and light transmission, belongs to the mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or c...
