How to change the color of float glass

Abstract

The invention belongs to the technical field of float glass, and in particular relates to a method for changing the color of float glass. The color changing method provided by the present invention includes: putting the color material into the feeding port, so that the color material and the colorless glass base material are continuously mixed to form a batch material, the batch material is heated and melted in the melting part to form molten glass, and the molten glass flows to the cooling After that, the molten glass flows into the tin bath for molding to prepare a glass plate; in the process of converting colorless glass into colored glass, the transmittance of the glass plate gradually decreases to a preset value; When the pass rate is lower than 89%, take out the agitator and the neck water bag, and increase the dilution air volume of the cooling part under the condition that the temperature fluctuation of the flow channel is controlled within ±5°C; when the transmittance of the glass plate reaches At the preset value, insert the agitator and the water bag of the neck into the neck, reduce the dilution air volume of the cooling part, so that the fluctuation of the temperature of the flow channel is controlled within ±5°C. It can solve the problem of long duration of color change period in the existing process.

Description

technical field [0001] The invention belongs to the technical field of float glass, and in particular relates to a method for changing the color of float glass. Background technique [0002] In the production process of float glass, glass material color conversion is a regular work. At present, there are mainly two methods to convert colorless glass into colored glass. One is to empty the colorless glass liquid and replace it with new colored glass batch materials; the other is to adopt the method of transitional replacement. , by properly adding coloring material and mixing with the colorless glass base material, the colorless glass is gradually transformed into colored glass. Compared with the first method, the second method does not require intermittent production and has low cost. However, the existing process of converting colorless glass into colored glass by the transition replacement method generally has problems such as long color change cycle, large production vo...
