Problems solved by technology

Therefore, the self-explosion rate of the tempered glass is relatively high during the tempering process, which brings relatively high cost pressure. Therefore, the present invention reduces the self-explosion rate of the dry half-baked glass through sodium chloride cooking. If cutting first and then tempering, the progress of the glass is likely to be insufficient. Therefore, it is necessary to cut the tempered glass. However, laser cutting is too wasteful and requires a large investment. Therefore, the present invention uses a liquid cutting method to improve the accuracy. unbreakable

Abstract

The invention provides a production method of toughened glass, and belongs to the field of glass production. The production method comprises the following specific steps: firstly pretreating glass: firstly putting flat glass into a high-temperature sodium chloride solution, and steaming for a period of time to obtain glass water; then primarily treating the glass: heating for a period of time in afirst zone, cooling through high-pressure cold air to a low-temperature state, and casting with a layer of organic glass water; then secondarily treating the glass: sequentially putting the glass into a second zone, a third zone and a fourth zone for heating; then toughening the glass: then putting the glass into a high-temperature potassium nitrate glycerol solution, cooling for a period of time, then putting the glass into glycerol, and treating for a period of time; then pretreating toughened glass: firstly printing the left and right sides of the toughened glass with acid-resistant ink through screen printing, and airing; and then cutting and moulding the toughened glass: putting the treated glass into a mixed solution containing hydrofluoric acid, hydrochloric acid and nitric acid.

Description

technical field [0001] The invention relates to a glass manufacturing method, in particular to a tempered glass manufacturing method. Background technique [0002] At present, tempered glass is widely used due to its high mechanical strength, excellent temperature resistance and good safety, etc. Most of the existing tempered glass production processes adopt the tempering process of air as the cooling medium. The heated glass is chilled by a large amount of air in a short time. Therefore, the self-explosion rate of the tempered glass is relatively high during the tempering process, which brings relatively high cost pressure. Therefore, the present invention reduces the self-explosion rate of the dry half-baked glass through sodium chloride cooking. If cutting first and then tempering, the progress of the glass is likely to be insufficient. Therefore, it is necessary to cut the tempered glass. However, laser cutting is too wasteful and requires a large investment. Therefore,...
