Problems solved by technology

[0004] Panel glass will produce some defective products after the electroplating film layer. In order to reuse the glass panel and save production costs, it is necessary to remove the FGAR coating layer and PVD coating layer on both sides of the panel glass. At present, the deplating solution is usually used to remove the film layer, but The existing deplating solution is easy to cause glass bending during the deplating process, making it impossible to reuse

Abstract

The invention provides a stripping process for the electroplating film layer of panel glass, comprising the following steps: A) immersing the panel glass in stripping solution A, stripping the FGAR film layer and ink layer; in terms of mass concentration, stripping solution A The ingredients are as follows: potassium hydroxide 10-12%, tetrahydrofurfuryl alcohol 5-8%, ethylenediaminetetraacetic acid 4-7%, sodium metasilicate pentahydrate 2-5%, hydroxyethylidene diphosphate 4-8%, 6-10% of triethanolamine, 0.1-0.5% of alkyl glycoside, 0.1-0.5% of isooctyl ether phosphate, and the balance is water; B) immersed in stripping solution B to strip the PVD film layer; based on mass fraction , the composition of stripping solution B is as follows: potassium hydroxide 18-25%, sodium gluconate 2-6%, sodium citrate 4-10%, tetrasodium EDTA 2-6%, potassium pyrophosphate 2-8% %, sodium silicate pentahydrate 0.5-2%, triethanolamine 4-10%, glycerol 1-2%, and the balance is water.

Description

technical field [0001] The invention belongs to the technical field of film treatment, and in particular relates to a deplating process of a panel glass electroplating layer. Background technique [0002] Mobile phones have been developed with multiple functions because of their portability. Among them, the camera function is the most frequently used item in people's daily life. Therefore, the effect of taking pictures is the focus of people's attention. [0003] The outside of the camera will be covered with a glass panel, but any object has a reflective effect on light, and the glass panel used by the camera is no exception. For the lens in an ideal state, the light can completely pass through the lens and be correctly reflected on the film. or full focus on the digital sensor. However, in fact, each kind of lens is limited by its own physical factors, resulting in aberrations. Therefore, it is impossible for a lens composed of many "problematic" lenses to allow all theor...
