It is widely applied to the fields of electrolysis, electroplating, catalysis, electrochemical water treatment, automobile exhaust treatment and the like. However, platinum is an expensive metal, and the resource is rare, which severely restricts the wide-range popularization. Therefore, the platinum-plated material is produced at the same time, and can save resources and reduce use cost when being used for replacing a pure platinum material.
For the platinizing process, in addition to a reasonably preferred configuration of the plating solution, a suitable anode is required to allow uniform distribution of the plating. Different parts to be plated need proper anodes to be matched, the conventional plated parts can finish the platinum plating task by using a flat plate anode, but the unconventional plated parts need anodes with special requirements to meet the requirements of work.
A coated titanium Anode, also called DSA (Dimensionally Stable Anode), is a new insoluble Anode material developed in the late 60 s of the 20 th century. Because of high electrocatalytic activity and excellent corrosion resistance, the material can be used as an important oxygen evolution and chlorine evolution electrode material in an acidic or alkaline medium, and is widely applied to the fields of chlor-alkali industry, electroplating, wastewater treatment, organic electrosynthesis, cathodic protection, aluminum foil and copper foil manufacturing and the like.
