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

Abstract

The invention discloses a deplating solution and a deplating process for removing glass NCVM film, and relates to the technical field of glass deplating. The deplating solution comprises the following components in terms of mass percentage: tetrasodium EDTA 15-35% , polyamino acid 1-5%, anionic surfactant 0.5-2%, and the rest is water. The stripping process uses the above-mentioned stripping solution to strip the NCVM film layer of the glass product. The invention alleviates the technical problems that the strong alkaline deplating solution traditionally used for the stripping of the NCVM layer is likely to cause damage to the photosensitive ink after exposure and development, and the product yield is low. The deplating solution of the present invention can not only remove the NCVM film layer cleanly, but also has a good deplating effect, and will not cause damage to the photosensitive ink after exposure and development. high.

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...
