Embodiment 1

[0031] A kind of processing technique that purity is 999.99‰ chain type gold jewellery, the steps are as follows:

[0032] (1) Raw material melting gold: Take high-purity gold with a purity of more than 999.994‰ as raw material, put the high-purity gold into the graphite pot of the high-frequency furnace to melt, pour it into the baked graphite tank, and use titanium as the gold material in the graphite tank Put the clip into strong hydrochloric acid for acid frying;

[0033] (2) material cutting: a, press the gold material of step (1) into a sheet material with a tablet press machine to obtain gold flakes; wherein, each time a gold sheet is passed through in the tablet press machine, the tablet press machine is scrubbed once with ethanol;

[0034] b. Pull the gold sheet into a tube shape with a tube drawing machine;

[0035] c. Use a musket to burn the tubular gold material red and cool it, then pinch the gap between the tubular gold material and flatten the gap with an agat...

Abstract

The invention belongs to the field of jewelry processing, and in particular relates to a processing process of chain type gold jewelry with purity of 99.999%. The processing process comprises the steps of melting raw material gold, cutting, polishing, forming chains, polishing, nailing and sanding, embroidering, forming chains, electroplating and detecting quality. The environmental cleanliness is emphasized in the preparation process, and the steel and iron tools used in the technological process are changed into diamond special tools, so that loss of gold material purity caused by reaction with the gold material is avoided, the gold jewelry with purity of 99.999% is prepared, the quality, the purity and the ornamental value of the gold jewelry are greatly improved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the field of jewelry processing, and in particular relates to a processing technology for chain gold jewelry with a purity of 999.99‰. Background technique [0002] With the improvement of people's living standards, people's desire to buy gold jewelry is increasing day by day, and the requirements for the appearance, purity and quality of gold jewelry are also constantly improving. The existing jewelry processing technology uses molten gold with a purity of more than 999.994‰ as a raw material, but in the process of processing jewelry, the purity of molten gold is usually lost, resulting in the purity of the gold jewelry produced can only reach 99.99%. Manufacturers cause economic losses and cannot meet the needs of consumers. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a processing technology for chain gold jewelry with a purity of 999.99‰....
