Problems solved by technology

[0003] The first technical problem to be solved by the present invention is that for the above-mentioned electroformed thousand-foot gold ornaments brought by the existing electroforming solution in the prior art, if the thickness of the product is not large, the hardness is not enough; if the thickness of the product is large, the The defect that more gold needs to be used provides an electroforming solution that can reduce the thickness of the electroformed product and have sufficient hardness

Abstract

The invention relates to a formulation of a BT48 hard gold electroforming solution, a preparation method of the electroforming solution and a process control condition of the electroforming solution. The BT48 hard gold electroforming solution is prepared by using a novel formulation, a novel preparation method and a novel process control condition. According to the technical scheme of the invention, electroformed 999 pure gold jewelry has the characteristics that: the hardness is up to HV100, the surface is smooth, the thickness is smaller than that of the prior jewelry, and the mass is 60 to 70 percent of that of the prior jewelry of the same volume, so a client can spend less money on the 999 pure gold jewelry of the same shape. In addition, the raw materials of formulation can be purchased easily, so the production is more convenient.

Description

technical field [0001] The invention relates to the field of electroplating, and more specifically, relates to a formula of BT48 electroforming solution for electroforming high-hardness millipede gold jewelry, a preparation method of the electroforming solution, and an electroforming process control condition of the electroforming solution. Background technique [0002] Gold jewelry, especially thousand-foot gold jewelry, is favored by consumers at home and abroad. Some of the existing thousand-foot gold jewelry are stamped and welded with thousand-foot gold foil, and some are processed by electroforming with BT48 hard gold electroforming liquid. , the existing processing methods have some deficiencies: the hardness of the thousands of pure gold ornaments welded after stamping with a mold is too soft, the surface is not smooth enough, it is necessary to manufacture stamping dies and welding machines, the initial investment is large, and there are some complicated thousand pur...
