Process for taking K gold jewelry from bottom water

Abstract

The invention discloses a process for taking K gold jewelry from bottom water and belongs to the field of jewelry treatment. The process is finished by the following steps of: (1) performing chemical polishing: arranging K gold jewelry in a reaction solution, and performing ultrasonic vibration; (2) performing primary washing; (3) performing magnetic polishing: putting the K gold jewelry in the water, adding a steel needle with the length of about 1cm and the diameter of 0.3-0.5mm, driving the steel needle to rotate through magnetic force, and slightly rubbing the steel needle and the surface of the K gold jewelry; (4) performing second washing; (5) cleaning the steel needle: adding a concentrated hydrochloric acid solution, heating and removing the steel needle; (6) grinding a gemstone inlaid position: grinding the gemstone inlaid position of the K gold jewelry manually; (7) removing wax: removing the milling wax at the manual grinding position by using an ultrasonic clearing machine; (8) performing third washing; and (9) drying: drying the K gold jewelry by using a hair drier. According to the process, the reaction cost can be reduced, the polishing efficiency is improved, the used reaction solution is non-toxic or harmless, the treatment is convenient, the effect is obvious, and a broken gold phenomenon is avoided.

Description

technical field [0001] The process for removing bottom water from K gold jewelry of the present invention belongs to the field of jewelry processing, and in particular relates to a process for removing bottom water from K gold jewelry without cyanide and electrolytic polishing. Background technique [0002] At present, in the jewelry manufacturing industry, K gold and other precious metal jewelry must be subjected to the bottom water process. The most important link is to polish the parts of K gold jewelry that cannot be manually polished as much as possible to make the jewelry more beautiful. There are two most common polishing methods for K gold jewelry, one is cyanide chemical polishing, and the other is electrochemical polishing. The main raw material used in cyanide chemical polishing contains cyanide. Because it is not environmentally friendly and the reactants are highly toxic, it is no longer the mainstream polishing method. The electrochemical method is to put K go...

Problems solved by technology

However, this method has a great impact on K gold jewelry, especially where it is relatively thin, K gold is easy to become brittle and easy to break

At the same time, the electrochemical method cannot polish the surface of K gold jewelry, and some places such as fine seams or folds may not be able to be polished.

In addition, this method requires additional electricity, which increases the operating cost, and it is not convenient to operate in large quantities, and the efficiency is low.
