Problems solved by technology

Traditionally, high-temperature and strong alkaline stripping solution is used to remove the NCVM film layer, but using this type of stripping solution for stripping is easy to cause damage to the photosensitive ink and screen printing cured ink after exposure and development, thus affecting the appearance quality of the product. Satisfy the production demand; while using high-temperature weak alkaline stripping solution or low-temperature strong alkaline stripping solution does not damage the ink, but the stripping effect on the electroplated NCVM film is poor, and the stripping of the NCVM film is not clean

Abstract

The invention relates to the field of glass deplating, in particular, it provides a deplating solution for removing a glass NCVM film layer, a deplating process and a glass product obtained by deplating. The described stripping solution that is used to remove glass NCVM film layer comprises pre-stripping solution, main stripping solution and auxiliary stripping solution; The pH of described pre-stripping solution is 7-8, and the pH of described main stripping solution The pH is 10-12, and the pH of the auxiliary stripping solution is 7-8. Using the above-mentioned specific pH pre-deplating solution, main deplating solution and auxiliary deplating solution to perform step-by-step deplating on the glass NCVM film layer, not only can effectively remove the glass NCVM film layer, but also will not damage the surface of the film layer Photosensitive ink or silk screen curing ink, etc., the deplating effect is good, and the product yield after deplating is high.

Description

technical field [0001] The invention relates to the field of glass stripping, in particular to a stripping solution for stripping glass NCVM film layers, a stripping process and a glass product obtained by stripping. Background technique [0002] With the progress of society, 2D, 2.5D or 3D glass has been applied to various electronic products and has become a fashion. Compared with traditional plastic and metal mobile phone battery covers, 2D, 2.5D or 3D glass is thinner, transparent and clean , anti-fingerprint, anti-glare, scratch resistance and weather resistance. Electroplating NCVM (Non-Conductive Vacuum Metalize, vacuum non-conductive electroplating) film on glass has become a fashion and a trend, so the requirements for the deplating process are becoming more and more stringent. [0003] NCVM is applied to glass products of electronic equipment, and a part of the NCVM product is selectively removed after coating, so as to give the coating layer a patterned effect. T...
