In the method of saturated salt solution electrolysis of caustic soda and chlorine to take the chemical industry known as chlor-alkali industry, the production technology for more than 100 years of history. Chlor-alkali production process of development, had tried platinum, iron oxide, carbon, artificial graphite electrodes, but the use of the effect is not ideal. The use of a mixture of precious metal coated titanium electrode, there are many advantages. Titanium anode material with a strong chemical resistance, low chlorine overpotential, good conductivity, high mechanical strength, ease of processing, low cost advantages. Xian Tai Jin Industrial Co., electrochemical techniques used in this field study of titanium anodes has 20 years of history, the formation of a complete set of exploration, production and testing system. Thai gold production company dedicated anode coating the membrane, the anode at a high current density (3000-4000A / m2), in a saturated saline solution, a life span of more than six years. Electrochemical Performance: Medium standard chlorine evolution potential susceptibility of oxygen evolution potential to strengthen the life of chlorine evolution environment HG / T 2471A ≤1.13V ≤28 ≥1200min ≥1.22V
