Problems solved by technology

[0002] The research on diamond synthesis technology has progressed rapidly, but the research on separation and purification methods in its subsequent treatment is relatively backward
The current artificial diamond purification process uses a large amount of strong volatile acids such as nitric acid, hydrochloric acid, and perchloric acid for treatment, which produces a large amount of harmful gases and acid mist during use, causing serious pollution to the environment
At the same time, the existing process still has problems such as cumbersome procedures, high energy consumption, low efficiency, and high cost.
This situation seriously restricts the production scale and quality of diamonds, and affects the development of my country's diamond industry.

Embodiment 1

[0026] Take 20 parts of water and 1 part of ethanol, after mixing, add 50 ppm of sodium lauryl sulfate, and add appropriate amount of hydrochloric acid to adjust the pH to about 3.0.

[0027] After the cleaning solution is prepared, put it into the cylinder of the magnetic polishing machine together with the magnetic grinding needle, and add 4 parts of diamond raw materials after electrolysis, shaking table, and magnetic separation processes.

[0028] Drive the disk of the polishing machine to rotate, after cleaning for 30 minutes, turn off the magnetic polishing machine, separate the fine graphite particles flotation from the foam by overflow, and turn on and off repeatedly until the graphite particles are completely flotation.

[0029] Then carry out the second cleaning, choose 20 parts of water and 0.8 parts of Fenton's reagent as the cleaning solution for the second cleaning, add an appropriate amount of hydrochloric acid to adjust the pH to 3.0, turn on the magnetic polish...

Embodiment 2

[0032] Take 30 parts of water and 2 parts of ethanol, after mixing, add 100ppm of sodium lauryl sulfate, and add appropriate amount of hydrochloric acid to adjust the pH to about 3.0.

[0033] After the cleaning solution is prepared, put it into the cylinder of the magnetic polishing machine together with the magnetic grinding needle, and add 4 parts of diamond raw materials after electrolysis, shaking table, and magnetic separation processes. Drive the disk of the polishing machine to rotate, after cleaning for 30 minutes, turn off the magnetic polishing machine, separate the fine graphite particles flotation from the foam by overflow, and turn on and off repeatedly until the graphite particles are completely flotation.

[0034] Then carry out the second cleaning, choose 30 parts of water and 1.2 parts of Fenton's reagent as the cleaning solution for the second cleaning, add an appropriate amount of hydrochloric acid to adjust the pH to 3.0, turn on the magnetic polishing mach...

Abstract

The invention provides a cleaning method of artificial diamond. Two kinds of cleaning liquids are adopted for cleaning the artificial diamond in sequence, the cleaning process is carried out in cooperation with a magnetic polishing machine, and the two reagents do not contain a large amount of strong volatile acid, so that corresponding pollution is not generated in the cleaning process, and the cleaning process is more environmental-friendly, does not cause environmental pollution, does not cause pollution to the operating condition at the same time and avoids harm to the body of an operator.According to the invention, the rubbing and material washing procedures of workers can also be reduced, and the labor load of the workers is reduced. The artificial diamond discharged by the magneticpolishing machine can meet the inspection standard after being dried.

Description

technical field [0001] The present invention relates to the purification technology of artificial diamond, specifically a kind of cleaning method of artificial diamond. Background technique [0002] The research on diamond synthesis technology has progressed rapidly, but the research on separation and purification methods in its subsequent treatment is relatively backward. The current artificial diamond purification process uses a large amount of strong volatile acids such as nitric acid, hydrochloric acid, and perchloric acid for treatment, which produces a large amount of harmful gases and acid mist during use, causing serious pollution to the environment. At the same time, the existing technology still has problems such as cumbersome procedures, high energy consumption, low efficiency, and high cost. This situation seriously restricts the production scale and quality of diamond, and affects the development of my country's diamond industry. The patent of the present inve...
