Abstract

The invention relates to a manufacturing technique for forming ultrawhite patterned glass, relating to the glass forming manufacturing technique field. The manufacturing technique comprises mixing, forming, annealing and detection cutting. The manufacturing technique is as follows: deferrization is performed on selected compositions; and raw materials after deferrization are mixed by weight portion: 59 to 64 portions of silica sand, 0.5 to 2.5 portions of aluminum hydroxide, 17 to 22 portions of sodium carbonate, 0.2 to 1 portion of anhydrous sodium sulfate, 0.3 to 2 portions of sodium nitrate, 13 to 18 portions of calcium carbonate and 0 to 0.5 portion of antimony trioxide. Under the condition of forming, the temperature of a rolling operation part is between 900 and 1100 DEG C, the rolling speed is between 145 and 220 meters per hour; the annealing temperature is between 60 and 590 DEG C, and the annealing time is between 0.1 and 0.3 hour. By application of the technique, the glass with high transmittance, low iron content, ideal flatness and good impact resistant effect is produced.

Description

technical field [0001] The invention relates to a production process of glass, in particular to a production process of ultra-clear embossed glass. Background technique [0002] At present, there are many kinds of patterned glass sold in the market, but they are all ordinary patterned glass. Its production process is a traditional glass production process. Embossed glass generally has disadvantages such as low light transmittance, unsatisfactory flatness, and poor impact resistance, which cannot meet the needs of people's modern life. [0003] The invention provides a production process of low-iron ultra-white patterned glass with high light transmittance, ideal flatness and good impact resistance by improving the existing production process of patterned glass. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the conventional glass production process and provide a production process capable of producing ultra-clear...
