What are the application areas of titanium anodes
The academic name of titanium anode is DSA anode, also known as titanium-based noble metal oxide anode, which is an insoluble anode. It is a new type of electrode that uses industrial titanium as the base material and is coated with precious metal oxide as the main component active coating through a special process. At present, it has been widely used in various fields, such as chemical industry, electroplating, water treatment, cathodic protection, environmental protection, marine anti-corrosion and other industries and fields.
(1) Application of coated titanium anode in chemical industry
1. Chlor-alkali industry
2. Chlorate production
3. Production of hypochlorite
(2) Application of Coated Titanium Anode in Industrial Wastewater Treatment
Electrolytic oxidation or electrochemical treatment of industrial wastewater, including the treatment of industrial water and factory wastewater, the electrode not only plays the role of transmitting current, but also catalyzes the oxidative degradation of organic matter. secondary pollution, known as green water treatment. In the process of the reaction of the anode, the organic matter in the sewage is electrochemically converted, directly or indirectly, into CO2 and water, which can effectively degrade COD and remove ammonia nitrogen.
(3) Application of Coated Titanium Anode in Electrolytic Silver Catalyst Production
Formaldehyde and acetaldehyde are important chemical raw materials. The use of electrolytic silver catalysts can achieve high efficiency and low energy consumption in formaldehyde production. However, platinum electrodes were used in the production of electrolytic silver catalysts in the past, and platinum was expensive and resources were scarce. Since titanium anodes are easy to manufacture, relatively cheap, and have good corrosion resistance, they have been used in production. The coated titanium anode shows good electrical conductivity and corrosion resistance in production, and the quality and activity of the silver catalyst produced meet the requirements.
(4) Application of coated titanium anode in electrolytic extraction of non-ferrous metals
The key technology of electrolytic extraction of non-ferrous metals lies in the selection and equipment of electrodeposition anodes. The selected anodes are required to be resistant to corrosion, have good stability, can be used for a long time, and have good electrocatalysis, so as to reduce the potential and tank voltage. At present, multi-component mixed ruthenium series, iridium series, platinum series coated titanium anodes have been widely used in domestic electrodeposition extraction of metals.
(5) Application of coated titanium anode in the production of ionized water by electrolysis
The benefits of alkaline ionized water on the human body are not described much. When the titanium anode produces ionized water, the tap water is filtered through the filter element and then enters the electrolytic cell that generates ionized water. After electrolysis, alkaline ionized water is produced in the cathode area. , producing acidic ionized water in the anode region. Select the titanium anode with excellent performance, the electrolyzed ion water can be comparable to the platinum-plated electrode, and the price is cheap, the service life is long, and it can be put into production in batches.
(6) Titanium anode for industrial electroplating
In the electroplating industry, the use of coated titanium anode can keep the plating solution in a stable state, and it is an electrode material with good acid corrosion resistance, especially in the application of gold plating, copper plating, chrome plating and rhodium plating, showing good performance.
