Titanium Anode (DSA), also known as Dimensionally Stable Electrode, is a new type of insoluble anode material developed in the late 1960s.
Traditional anode materials are broadly classified into three categories: platinum, graphite, and lead alloy anodes. Platinum is expensive, graphite and lead alloy anodes undergo high-current electrolysis, corrosion, poor corrosion resistance, large oxygen evolution potential, low electrochemical catalytic performance, high energy consumption, especially the toxic lead in the anode will dissolve in the solution, resulting in Secondary pollution and degrade coating performance.
Application of DSA coated titanium anode
DSA coated titanium anodes are mainly used in two major departments of electrochemistry and electrometallurgy.
The fields of DSA coated titanium anode applications are: chlor-alkali industry, chlorate production, hypochlorite production, perchlorate production, persulfate electrolysis, electricity
Solution organic synthesis, electrolytic extraction of non-ferrous metals, production of electrolytic silver catalyst, electrolytic production of copper foil, electrolytic oxidation recovery of mercury, water electrolysis, preparation of chlorine dioxide, hospital sewage treatment, cyanide-containing wastewater treatment in electroplating plants, domestic water Disinfection with food utensils, treatment of cooling water in power plants, treatment of dyeing and finishing wastewater in woolen mills, treatment of industrial water, preparation of acid-base ionized water by electrolysis, galvanizing of copper plates, rhodium plating, palladium plating, gold plating, lead plating, Electrodialysis method for desalinating seawater and electrodialysis to prepare tetramethylammonium hydroxide, molten salt electrolysis, battery production, cathodic protection, production of negative electrode foil, and anodization of aluminum foil. Applications include chemical, metallurgical, water treatment, environmental protection, electroplating, electrolytic organic synthesis and other fields.
In recent years, in the surface treatment industry, the application of DSA coated titanium anodes has seen new trends. Such as adding some kind of nano material to the coating to improve
The electrocatalytic activity of the DSA anode, as in some specific plating solutions, is achieved by adjusting the oxygen evolution potential of the DSA coating to suppress certain impurity ions.
Produce to ensure the stability of the bath. With the deepening of research on DSA coated titanium anodes, its application prospects will become more and more broad.
