What are the applications of titanium anodes in the chlor-alkali industry?
Jun 12, 2024
Titanium anodes are widely used in the chlor-alkali industry. The main products involved in the chlor-alkali industry include caustic soda, polyvinyl chloride, hydrochloric acid, liquid ammonia and other organic and inorganic chemical products. The main application of titanium anodes in this industry is to produce caustic soda through electrolysis of salt water solutions. At the same time, ammonia gas is produced at the anode, and gas and caustic soda are produced by the cathode reaction.
As an electrode material, titanium anode has many advantages, making it widely used in the ammonia-alkali industry. First, titanium has good chemical durability and good machinability, which makes it a great advantage in electrolytic cell design. Secondly, the oxide film generated on the titanium surface is very thin and dense, and has strong corrosion resistance, especially under high overpotential conditions, its corrosion resistance is particularly excellent. Furthermore, the metal oxide coating on the titanium anode has low resistivity, good conductivity, stable chemical composition of the coating, stable crystal structure, stable electrode size, good corrosion resistance, and long life, which is conducive to reducing Overpotential for oxygen evolution and chlorine evolution reactions, saving electric energy.
In addition, compared with graphite electrodes, the use of titanium anodes in ammonia-alkali production has the advantages of small loss, greatly reduced ammonia evolution potential, stable size and shape, etc. Using titanium anodes in the same electrolysis environment can achieve higher product quality, lower energy consumption, and higher purity ammonia. At the same time, titanium anodes have high current efficiency, low energy consumption, and long working life, even in After the electrode loses its activity, its matrix can be reused.
In general, the application of titanium anodes in the chlor-alkali industry covers the entire process from the electrolysis of salt water solutions to produce caustic soda to the production of hydrogen, chlorine and other related products. It improves production efficiency, reduces energy consumption, improves product quality and prolongs Equipment service life and other aspects have played an important role.
Di Noer Technology specializes in the production of titanium anode products with various geometric shapes. Generally, customers in the chlor-alkali industry mainly use plate electrodes and mesh electrodes. The coating generally uses ruthenium-iridium oxide coating, but the shape of substrate materials and coating formula can also be customized according to customer requirements to meet customer requirements for different environments and service life. Customers are welcome to inquire about related products.
