Embodiment 1

[0057] Take 60 jin of quartz sand, 28 jin of flux soda ash, 5.5 jin of borax, 0.7 jin of colorant cadmium red, 0.4 jin of cadmium yellow, 0.1 jin of selenium powder, 3 jin of potassium carbonate and 2 jin of zinc oxide for stirring, brightener hydrogen Alumina is 0.3 catties, and the total feeding amount is 100 catties.

[0058] After mixing the above raw materials, melt them into fluid glass at a high temperature of 1500°C in a crucible furnace, use one end of the blowpipe 4 to pick up the fluid glass and blow it into glass pellets, and insert the other end into the gas nozzle 3-4. The blowing device blows the small ball into a large glass sphere with an arc of 200°. After the glass ball is cooled, it is broken and cut into a rectangular spherical colored decorative glass piece with four corners at 90°, length 90mm, width 70mm, and thickness 0.3mm. , which is made into red decorative glass products.

[0059] The structure of the blowing device and the blowing method thereof f...

Embodiment 2

[0067] Get 80 jin of quartz sand, 15.7 jin of flux soda ash and 2 jin of sodium nitrate, 5 grams of colorant cobalt oxide, 2 jin of borax, 0.29 jin of antimony oxide as a precipitating agent, and a total feeding amount of 100 jin.

[0068] The smelting temperature is 1300°C, and the glass ball with a spherical curvature of 180° is blown by a blowing device for manufacturing spherical decorative glass. The thickness of the glass sheet is 0.5 mm, and its back is silver-plated. The rest are the same as in Example 1. The product is a blue decorative glass sheet.

Embodiment 3

[0070] Take 35 catties of quartz sand, 10 catties of soda ash as a flux, 2 catties of cadmium yellow as a colorant, 3 kg of borax, 3 catties of potassium carbonate as a propping agent, 4 catties of aluminum hydroxide as a brightener, and the rest as clinker.

[0071] The smelting temperature is 1400°C, and the spherical surface arc is 150° of glass balls blown by a blowing device for spherical decorative glass. The thickness of the glass sheet is 1.1mm. The rest are the same as in Example 1, and the product is a yellow decorative glass sheet.

Abstract

A process for preparing decorative color sheet includes proportionally mixing quartz sand, flux, coloring agent and borax, high-temp smelting, blowing glass ball by a blowing mechanism, cooling and cutting. Its advantages are high toughness and strength, high productivity, and high of finished products.

Description

technical field [0001] The invention relates to a production process of glass, in particular to a production process of colored glass sheets. Background technique [0002] At present, most of the domestic production of flat colored glass has no three-dimensional effect, and there are only several monotonous colors such as brown, blue, and gray; or the colored coating is applied to the back of ordinary transparent colorless glass to obtain various colors, but the product The reflective performance is poor, and it is easy to remove the film and fade after a long time; even if there are curved colored decorative glass sheets produced abroad, their production process is produced by a pool furnace, which requires two moldings, that is, the first time it can only be drawn into a flat plate , the second heating and pressing into a curved glass with a certain thickness, the pool furnace is expensive, the assembly line is long, and the investment is large. When replacing the raw mate...
