Problems solved by technology
The huge impact force is easy to cause the deformation of the copper fixture. The longer the use time (especially the relatively thin copper fixture), the greater the deformation, and the service life of the copper fixture is greatly reduced.

Embodiment Construction
[0008] A process for removing the coating on the surface of the optically coated copper jig. First, the optically coated copper jig that needs to be removed from the surface coating is soaked in ammonium bifluoride solution for 10 minutes, so that the coating layer on the surface of the optically coated copper jig becomes brittle and falls off. ; Then take out the optical coating copper jig and clean it and air dry it; then process the air-dried optical coating copper jig with a sandblasting process to remove the surface coating layer remaining on the optical coating copper jig. The weight ratio of ammonium bifluoride to water in the ammonium bifluoride solution is 1:1.

The invention discloses a treatment process for removing a surface coating of an optical coating copper jig. The process comprises the following steps: 1, putting the optical coating copper jig, the surface coating of which needs to be removed, in an ammonium hydrogen fluoride solution to be soaked for a period of time, wherein the surface coating is embrittled and falls; 2, taking out the opticalcoating copper jig to be cleaned and air-dried; and 3, treating the air-dried optical coating copper jig by means of an abrasive blasting process to remove the surface coating left on the optical coating copper jig. The reatment process for removing a surface coating of the optical coating copper jig disclosed by the invention can remove the coating on the surface of the optical coating jig effectively, and meanwhile, damage to the optical coating jig is reduced, and the service life of the optical coating jig is prolonged.
Description
technical field [0001] The invention relates to a process for removing the coating on the surface of an optical coating copper fixture. Background technique [0002] Copper material is relatively soft, easy to machine, high temperature resistant, not easy to deform, etc. It is widely used in jigs for optical coating products. However, while the copper fixture is continuously used to load the product coating, the surface of the copper fixture will also continuously deposit optical coating materials. When the surface film layer reaches a certain thickness, the surface film layer is easy to fall off, resulting in bright spots when the optical product is formed, and blocking the optical product. film, so it is necessary to remove the coating layer on the surface of the copper fixture. At present, the surface of the copper fixture is sandblasted. The sand ejected by the sandblasting machine needs to form a pressure of 7-8 kg on the surface of the copper fixture to remove the coa...
