Embodiment Construction

[0020] The specific implementation manners, features and effects thereof proposed according to the present invention are described in detail below.

[0021] The present invention is used for depositing the gold depositing solution of pure gold ceramic restoration crown, which mainly consists of the following formula: the gold depositing solution contains Au: 4-25g / L, sulfite: 120-180g / L, phosphate: 50 ~80g / L, brightener and stabilizer: 1~2g / L, PH value 8~10. The solution is suitable for pulsed direct current electrodeposition, and the cathode reaction equation is: . The deposition solution is colorless, non-toxic, non-irritating, has strong stability, and is suitable for long-term electrodeposition and long-term storage.

[0022] In this formula, gold is the main salt, and gold is allowed to change within the range of 4-25g / L; sulfite is the main complexing agent, which can be appropriately excessive during the preparation process, which is beneficial to improve the con...

Abstract

A golden depositing liquid is used for repairing pure gold porcelain fused inner crown, which is non - cyanogen sulfite pure gold depositing liquid without adding any other metallic element. Said depositing liquid composition is golden depositing liquid containing Au 4-25 g / L, sulfite 120-180 g / L, phosphate 50-80 g / L, brightness and stabilizer 1-2 g / L, PH value 8-10.It adopts phosphate as buffering agent, multi - dentate fatty amine as stabilizer, at least a phosphate group compound as brightener. Said depositing liquid is achromatism, innocuity, nonirritant odor, strong stability quality, suitable for long time electrolytic deposition and saving.

Description

technical field [0001] The present invention relates to a cyanide-free sulfite pure gold depositing solution, more precisely to a pure gold deposition liquid for making dental porcelain restoration pure gold inner crowns without adding any other base metal additives. Invention of gold deposition solution for porcelain restoration crowns. Background technique [0002] Electrodeposition technology has a history of hundreds of years. The workpieces made by this method are more precise than those made by any other method. It can reproduce any tiny details on various complex mandrels. Among them, the alkaline sulfite electrodeposition pure gold process is widely used because of its non-toxicity, stability and other advantages, and because of these advantages, it is more and more used in the dental restoration industry that requires extremely high quality deposits. [0003] However, almost all sulfite gold deposition solutions currently on the market add trace amounts of base met...
