Problems solved by technology

Chemical treatment is suitable for cleaning thin plate parts, but the disadvantage is that if the time is not properly controlled, even if a corrosion inhibitor is added, the steel will be over-corroded. For more complex structural parts and parts with holes, pickling with acid solution Afterwards, the remaining acid immersed in the crevices or holes is difficult to completely remove. If it is not handled properly, it will become a hidden danger of future corrosion of the workpiece, and the chemicals are volatile and costly. The chemical discharge after treatment is difficult. serious pollution of the environment
[0005] Surface treatment of Moissanite rarely occurs in the existing literature, and the research on its surface treatment technology is not very mature, so the present invention further develops and processes it

Abstract

The invention discloses a moissanite surface treatment technology. The moissanite surface treatment technology comprises the following steps that firstly, moissanite is placed in deionized water at 45-55 DEG C to be subjected to ultrasonic washing for 1-2 h, the ultrasonic power is 10-50 W, ultrasonic treatment is conducted for 10-20 min, and then, the moissanite is taken out and subjected to airdrying till the surface water content is 4-10%. According to the moissanite surface treatment technology, ultrasonic washing is conducted, surface soil containing impurities and other impurities are removed, then, high-purity nitrogen high-temperature treatment is conducted, and sparse deterioration happens to the moissanite surface structure, so that the moissanite surface structure is easily treated through first-level treating fluid; and through first-level treating fluid treatment, metal impurities are removed firstly, and meanwhile the moissanite can be finely ground through added silicondioxide.

Description

technical field [0001] The invention relates to the technical field of moissanite treatment, in particular to a moissanite surface treatment technology. Background technique [0002] Moissanite, the chemical name is synthetic silicon carbide, its appearance is very similar to diamonds, and it needs to be identified by observing its inclusions with a magnifying glass of at least 10 times. It is the latest diamond imitation. The brightness and refractive index of moissanite are higher than that of diamond, making it the most shining gemstone in the world. What is rare is the fire, which is dazzling and seductive, and becomes the focus of attention. Its hardness is as high as 9.25, second only to diamonds, becoming the second hardest gemstone in the gem world. Normal wear can maintain its brightness, clarity, and fire characteristics. Moissanite is popular among fashionable and independent women in Europe, America, Hong Kong, Taiwan, Japan, South Korea and other markets, and ...
