In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an embodiment of the present application provides a method for preparing velvet gold, which includes the following specific steps:
In the embodiment, the noble metal is uniformly blasted by 360 degrees, wherein the blasting is carried out by taking compressed air as power to form a high-speed blasting beam to spray the blasting material to the surface of a workpiece to be processed at a high speed so as to change the surface of the noble metal; the noble metals include 18k, 5G gold, traditional gold, etc.
Specifically, the sand blasting pressure in the sand blasting process is 0.2-0.6Mpa, the noble metal is subjected to sand blasting for 360 degrees under the sand blasting pressure of 0.2-0.6Mpa, and the sand blasting time is maintained for 2-5 minutes.
And 102, carrying out wet car sanding treatment on the precious metal subjected to sand blasting treatment.
In this embodiment, the precious metal subjected to the sand blasting is subjected to wet sanding, and the precious metal is subjected to wet sanding by polishing the surface of the precious metal with a grinding wheel, so that the surface of the precious metal maintains a grainy feel.
Specifically, the rotating speed of the grinding wheel is controlled between 500 and 1000r/min during the wet sanding treatment of the precious metal.
And 103, soaking the precious metal subjected to the wet car sand treatment in a softening agent.
In this embodiment, the precious metal after wet car sand treatment is soaked in the softening agent for a period of time, mainly to soften the surface of the precious metal and increase the brightness of the precious metal.
Specifically, the softener includes a surfactant, bright oleic acid, fatty acid, and water. The softening agent can soften the surface of the noble metal and increase the brightness of the surface of the noble metal.
And 104, grinding and polishing the softened noble metal.
In this embodiment, the softened noble metal is polished to make the surface of the noble metal smoother and glossy.
Specifically, in the embodiment of the present application, the surface of the noble metal is polished by a white cloth wheel and polishing wax, and the rotation speed of the polishing machine is controlled between 2500-.
And 105, cleaning, grinding and polishing the noble metal, and drying the noble metal to obtain the velvet gold.
In this embodiment, the noble metal after polishing is cleaned and then dried.
Specifically, the precious metal is placed in an oven at 150 degrees for drying, and the drying apparatus is not limited herein.
In this embodiment, after the precious metal is treated by the method provided in this embodiment of the application, a layer of oily and bright effect is further added on the surface of the precious metal on the basis of keeping the grainy feeling of the sand surface, and the treated precious metal has a smooth hand feeling, uniform color and strong stereoscopic impression just like a velvet fabric, so the treated precious metal is also called velvet gold, and the treated precious metal is more wear-resistant and is not easy to grind.
In the embodiment of the present application, the refinement process of velvet gold is specifically as follows:
uniformly blasting the noble metal for 2-5min at 360 degrees under the sand blasting pressure of 0.2-0.6 Mpa;
