Deplating solution and deplating technology for removing glass NCVM film layer

Abstract

The invention discloses a deplating solution and a deplating technology for removing a glass NCVM film layer, and relates to the technical field of glass deplating. The deplating solution comprises the following components by mass percentage: 10-30% of soluble carbonate, 5-15% of a complexing agent, 1-5% of penetrant and the balance of water. In the deplating technology, the deplating solution isused for deplating the NCVM film layer of a glass product. By adopting the deplating solution and the deplating technology provided by the invention, the technical problems that a strong alkaline deplating solution used for the removal of the NCVM film layer easily causes damage to photosensitive ink after exposure and development and the product yield is low in a traditional technology are alleviated. The deplating solution provided by the invention mainly uses the soluble carbonate as a main deplating agent, and by cooperating with the complexing agent and the penetrant, not only can the NCVM film layer be cleanly removed with a good deplating effect, but also no damage is caused to the photosensitive ink after exposure and development, and the glass product after being deplated with thedeplating solution has a good appearance and a high yield.

Description

technical field [0001] The invention relates to the technical field of glass deplating, in particular to a deplating solution and a deplating process for stripping glass NCVM film layers. 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. At present, the deplating process has been well used on glass as a new type of operation method. This process can not only obtain beautiful and precise patterns, but also the patterns have no concave-convex feeling and fine texture. [0003] NCVM (Non-Conductive Vacuum Metalize, vacuum non-conductive electroplating) is a non-conductive vacuum metallization coating process. NCVM uses special metals. This process not only makes the coated f...

AI Technical Summary

Problems solved by technology

Traditionally, a 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 after exposure and development, affecting the appearance quality of the product, which cannot meet the demand, and The current deplating process has low production efficiency and unstable product yield
