Embodiment Construction

[0022] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0023] A gold aging treatment method, comprising a pre-treatment process, a gold casting process, a post-treatment process and an old-fashioned process, the pre-treatment process has the following steps:

[0024] 1) Starting plate: measure the size of the sample of the gold product to be processed, conduct pattern approval, and carve the sample with oil sludge;

[0025] 2) Inverting the mold: pour the engraved sample into the mold, after the mold is turned over, inject wax into the rubber mold, vacuumize the sample, and make the wax mold; specifically, the inverted mold includes pouring the glue and turning over the mold. The two-step process of receiving wax is the process of pouring glue and turning over the mold. The surface layer of the sample is covered wi...

Abstract

The invention relates to an antiquing treatment method of gold, which comprises a pretreatment process, a gold casting process, a post-treatment process and an antiquing process; the antiquing processcomprises the following steps: adding ferric trichloride into purified water, uniformly stirring, heating and dissolving to form a ferric trichloride solution; adding a chlorine dioxide agent A intothe purified water and dissolving to form a chlorine dioxide agent A solution; adding a chlorine dioxide B agent into the purified water and dissolving to form a chlorine dioxide B agent solution; andmixing the chlorine dioxide agent A solution and the chlorine dioxide agent B solution, uniformly stirring, pouring into the ferric trichloride solution, adding acetic acid to form an antiquing solution, and soaking gold in the antiquing solution. The antiquing solution is mainly prepared from ferric trichloride, and the chlorine dioxide agent A, the chlorine dioxide agent B and the acetic acid are used as additives to adjust the color of the antiqued product, so that the antiquing solution is attached to the surface of gold and is brown red. Gold obtained through the antiquing method has thematte effects of being mild in color, lustrous but not dazzling and obvious but not expensive.

Description

technical field [0001] The invention relates to an old gold treatment method and old gold, belonging to the technical field of electroplating hard gold. Background technique [0002] With the development and utilization of gold products in various fields, people have higher and higher requirements for the quality, volume and hardness of gold products, and the shape of gold products is becoming more and more complicated. In the prior art, the electroforming gold process can It breaks through the shortcomings of the previous gold processing technology, such as simple shape, rigid shape, and difficult variety. The gold products obtained by the electroforming gold process have unique shapes and changeable shapes, and are especially suitable for making hollow gold products. [0003] The existing electroforming gold process includes a pretreatment process, a gold casting process and a post-treatment process. The pre-treatment process is used to make a wax model of the gold product...
