Embodiment 1

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

[0058] After mixing the above raw materials, smelt it into fluid glass at a high temperature of 1500℃ in a crucible furnace. Use one end of the blowpipe 4 to blow the fluid glass into small glass balls, and insert the other end into the gas nozzle 3-4. The blowing device blows the small ball into a large glass sphere with a curvature of 200°. After cooling, the glass ball is broken into a rectangular spherical colored decorative glass piece with four corners of 90°, length 90mm, width 70mm, and thickness 0.3mm. , Which is made into red decorative glass products.

[0059] The structure of the above-mentioned blowing device for manufacturing spherical decorative glass and its blowing ...

Embodiment 2

[0067] Take 80 kilograms of quartz sand, 15.7 kilograms of flux soda ash and 2 kilograms of sodium nitrate, 5 grams of colorant cobalt oxide, 2 kilograms of borax, 0.29 kilograms of antimony oxide as a sedimentation agent, and 100 kilograms of total material.

[0068] The smelting temperature is 1300°C, and the spherical decorative glass blowing device is used to blow glass balls with a spherical curvature of 180°. The glass sheet has a thickness of 0.5 mm and the back surface is silver-plated. The rest are the same as in Example 1. The product is blue decorative glass.

Embodiment 3

[0070] Take 35 kilograms of quartz sand, 10 kilograms of soda ash as flux, 2 kilograms of cadmium yellow as colorant, 3 kilograms of borax, 3 kilograms of potassium carbonate as propping agent, 4 kilograms of brightener aluminum hydroxide, and the rest is clinker. The total amount of feed is 100 kilograms.

[0071] The smelting temperature is 1400°C, and a glass ball with a spherical curvature of 150° is blown by a blowing device for making spherical decorative glass. The glass sheet has a thickness of 1.1 mm. The rest is the same as in Example 1. 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 method for producing glass, in particular to a method for producing colored glass sheets. Background technique [0002] At present, most of the domestic production of flat colored glass has no three-dimensional effect, and only has a few monotonous colors such as brown, blue, and gray; or uses colored coating on the back of ordinary transparent colorless glass to obtain various colors, but the product The reflection performance is poor, the film is easy to peel off and fade after a long time; even if there are curved colored decorative glass sheets in foreign countries, their production process is produced in a pool furnace, and it needs to be formed twice, that is, the first time it can only be drawn into a flat plate , The second heating and pressing into a certain thickness of curved glass, the pool furnace is expensive, the assembly line is long, and the investment is large. When replacing the raw materials, the replaced raw m...
