Method for preparing titanium salt for cyanideless electro-plating cadmium titan

Abstract

The invention provides a method of preparing titanium salts for cyanideless electroplating cadmium-titanium, relating to a method for preparing titanium salts which are main materials in cyanideless electroplating cadmium-titanium process, belonging to surface treatment technique. The method is characterized in that: the preparation method comprises the steps of preparations of drugs and titanium salts. The method of the invention is capable of preparing the titanium salts with high quality needed in the cyanideless electroplating cadmium-titanium technique, meets requirements of the cyanideless electroplating cadmium-titanium technique, and facilitates the popularization of the cyanideless electroplating cadmium-titanium technique.

Description

Technical field

[0001] The invention belongs to surface treatment technology and relates to a preparation method of the main component titanium salt in the cyanide-free cadmium-titanium electroplating process. Background technique

[0002] For the surface protection of high-strength steel, cyanide-containing cadmium-titanium electroplating process is mostly used to reduce the harm of hydrogen embrittlement to high-strength steel. For this kind of electroplating technology, its main functional component titanium salt determines the stability and reliability of the process. Cyanide-free cadmium-titanium electroplating process has emerged in China. This process eliminates the highly toxic cyanide, which is beneficial to the protection of the environment and the safety of operators. However, how to prepare the titanium salt as the main component of the electroplating formula, there is no public literature to learn from, and there is no domestic enterprise that produces the above tita...
