Pure gold double-set necklace surface nondestructive processing process

Abstract

The invention relates to the technical field of pure gold accessory surface treatment, and discloses a pure gold double-set necklace surface nondestructive processing process. The process comprises the steps that multiple pure gold double-set necklaces are fixed to a lifting frame, the lifting frame is put into a cleaning tank, treatment liquid is contained in the cleaning tank, the treatment liquid comprises, by mass percent, 10 to 15% of hydrogen peroxide, 18 to 22% of phosphoric acid and the balance water according to the mass amount of 100%; b, the pure gold double-set necklaces are subjected to standing in the treatment liquid for 3 to 5 min; c, the treatment liquid is heated to 55 to 60 DEG C through a heater, and the temperature is kept for 8 to 10 min; d, the treatment liquid is heated to 80 to 90 DEG C through the heater, and the temperature is kept for 2 to 4 min; and e, the pure gold double-set necklaces are taken out, rinsed through clean water and then dried, and the puregold double-set necklace finished products with the surface color and luster degree meeting the requirement are obtained. The pure gold double-set necklaces are treated, the dirt, the metal, and metaloxide on the surfaces of the pure gold double-set necklaces can be directly removed, and clean and bright effects of the surfaces of the pure gold double-set necklaces can be kept.

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 ...

Problems solved by technology

[0003] However, due to structural problems such as the complex links and weak joints of the double-set necklaces of the "Thousand Pure Gold" and "Pure Gold" approved widening mechanisms, the traditional treatment process for surface treatment will cause product chains The deformation and damage of joints make the overall quality of the product not meet the product quality standards
