Problems solved by technology

This patented technology mainly considers avoiding damage to the structure of the thousand-pure gold double-set necklace, and the surface treatment strength is not enough. Moreover, relying on phosphoric acid to remove metal oxides may form insoluble phosphate attached to the surface, and the color of the final product is still not pure. Golden shiny luster effect

Abstract

The invention provides a color guiding process of scratch-resistant pure gold products, which combines five acids, nitric acid, phosphoric acid, citric acid, hydrochloric acid and sulfuric acid, to make a boiling potion, and first soaks the scratch-resistant pure gold products in the boiling potion , then soak in boiling water, and compare the color with the original color plate of pure gold. If the color is inconsistent, then use boiling liquid medicine and boiling water to soak in cycles until the color is consistent, which can effectively guide the pure gold products in the scratch-resistant surface treatment. The chromatic aberration produced on the surface makes the scratch-resistant pure gold products present the original color of full golden yellow, and the luster is shining.

Description

technical field [0001] The invention relates to the technical field of preparation of pure gold products, in particular to a color guiding process for scratch-resistant pure gold products. Background technique [0002] Gold is a precious metal. It is not only used as a special currency for reserves and investment, but also an important material for jewelry, electronics, modern communications, aerospace and other sectors. In particular, gold jewelry has always been loved by people and occupies a very high proportion in the Chinese jewelry market. [0003] Regarding the fineness of the gold content of gold products, the national standard has very clear regulations, that is, every gold jewelry sold by a merchant must be listed to indicate its gold content and weight, and the gold content is not less than 99%. However, due to the nature of pure gold is relatively soft, low in hardness and difficult to process, it is also easy to scratch and leave scratches during people's daily...
