Glass stripping agent and glass stripping process

Abstract

The invention discloses a glass stripping agent and a glass stripping process. The glass stripping agent comprises the following components by mass percentage: 1-3% of soluble alkali metal hydroxide; 1-3% of sodium carbonate or sodium bicarbonate 5%; triethanolamine or monoethanolamine 3-10%; detergent 0.2-0.8%; the rest is water. The glass stripping process uses the above-mentioned glass stripping agent to strip the glass product. The invention alleviates the traditional glass stripping agent is not environmentally friendly, the stripping effect is not good, and the technical problems such as tooth loss, edge penetration, over-recession, trachoma and ink drop are easy to occur, and the glass stripping agent of the invention can not only effectively It can effectively remove the excess coating after glass screen printing, and the stripping effect is good, and it can prevent the glass substrate from being corroded and scratched, and effectively protect the screen printing ink. The glass products after stripping have good appearance and high yield.

Description

technical field [0001] The invention relates to the technical field of glass deplating, in particular to a glass deplating agent and a glass deplating process. Background technique [0002] With the progress of society, 2D, 2.5D or 3D glass has been used in various electronic products. Glass products need to go through material cutting, CNC (Computer numerical control, CNC machine tool), polishing, tempering, cleaning and coating in the production process. (coated with titanium-silicon coating) and a series of special processing techniques such as silk screen printing. According to actual needs, after the coating is completed, a certain pattern of ink will be screen-printed on the coating, and then the stripping agent will be used to remove the coating that is not covered by the screen printing ink to obtain a satisfactory product. [0003] At present, the deplating process of glass coating is carried out in the following way: in the deplating tank with a certain liquid car...

AI Technical Summary

Problems solved by technology

[0005] 1. Poor deplating: tooth loss, edge penetration, over-removal, trachoma and ink loss are prone to occur, which affect product quality and cannot meet production needs;

[0006] 2. Strong alkali deplating solution is volatile under high temperature conditions, corrodes equipment, and is harmful to operators and the environment
