Abstract

The invention discloses a chemical silvering and pretreatment process for a synthetic quartz diamond pavilion. The process comprises the following steps: wetting and rough washing, deoiling with deoiling liquid 1, scrubbing, deoiling with deoiling liquid 2, coarsening, cleaning and sensitizing; and then implementing the chemical silvering by using a jet plating or dip plating manner. At the same time of completing the pretreatment process, the process adopts proper coarsening and sensitizing process and silvering liquid formula, so that the silvering layer adhesion of silvered products is improved, and the phenomenon of silvered layers becoming yellow, black and white is avoided.

Description

technical field [0001] The invention belongs to the artificial crystal diamond silver plating process, in particular, the invention relates to the chemical silver plating and pretreatment process of the artificial crystal diamond pavilion. Background technique [0002] Man-made crystal diamonds (referred to as rhinestones) are a wide range of jewelry accessories, mainly used in jewelry, handicrafts, clothing, footwear and other fields. At present, the manufacturing process of rhinestones is mainly divided into two steps. The first part is the shape manufacturing of rhinestones (semi-finished products), which mainly rely on equipment (grinding machines, polishing machines) to be realized by manual operation, automatic or semi-automatic control. The second part refers to the semi-finished products. Subsequent processing, the process is mainly composed of cleaning, mold suction, inspection, re-cleaning, silver plating, painting and other processes. The present invention mainl...
