Abstract

The invention relates to the technical field of surface treatment of thousands of pure gold ornaments, and discloses a non-destructive treatment process for the surface of a thousand pure gold double-set necklaces. In the tank, the cleaning tank is equipped with treatment liquid, which includes 10%-15% hydrogen peroxide and 18%-22% phosphoric acid in terms of mass percentage, and the balance is water according to the total amount of 100%; b. The gold double-set necklace is left to stand in the treatment solution for 3-5 minutes; c. Heat the treatment solution to 55-60°C through a heater and keep it for 8-10 minutes; d. Heat the treatment solution to 80-90°C through a heater, Keep it for 2-4 minutes; e. Take out the double-set necklace of pure gold, rinse it with clean water and then dry it to obtain the finished double-set necklace of pure gold whose surface color meets the requirements. After the pure gold double set necklace is processed by this process, the oil, metal and metal oxides on the surface of the thousand pure gold double set necklace are directly removed to keep the surface of the thousand pure gold double set necklace clean and bright.

Description

technical field [0001] The invention relates to the technical field of surface treatment of thousands of pure gold ornaments, in particular to a surface non-destructive treatment process of a thousand pure gold double-set necklace. Background technique [0002] Surface treatment is an important process in the production process of "thousand pure gold" and "pure gold" jewelry. The main purpose of surface treatment of semi-finished jewelry after processing is to obtain the appearance color and luster required by product design. Thousands of pure gold jewelry are transferred between multiple production processes, so that oil, grease, metal powder (mainly iron, copper and other metals), metal oxides, etc. will remain on the surface of the thousand pure gold jewelry, so that the surface of the jewelry will lose its luster or glossiness. It meets the requirements, so surface treatment is required for jewelry. The traditional treatment process is usually to remove the physical and ...
