Method for deplating sapphire plated layer by using waste polishing solution
The invention relates to a method for deplating a sapphire plated layer by using a waste polishing solution, belongs to the technical field of glass surface treatment and aims at realizing reuse of the waste polishing solution in an AG (anti-glare glass) process and further ensuring the performance of sapphire after deplating. The invention provides the method for deplating the sapphire plated layer by using the waste polishing solution. The method comprises the following steps: mixing the waste polishing solution produced in the AG process and water to form a mixed solution, and controlling the pH value below 1 for further deplating treatment; soaking the surface-coated sapphire to be deplated in the mixed solution, performing deplating treatment, and cleaning with the water after deplating treatment to obtain a corresponding product. By adopting the method provided by the invention, the reuse of the waste polishing solution is realized, thereby turning waste into treasure, improving economic benefits and further ensuring the crystal purity, the surface roughness and the transmittance of the sapphire after deplating; and furthermore, the process flow is simple and the operation is easy.
