The chemical industry that produces chlorine gas and caustic soda by electrolyzing saturated salt aqueous solution is called the chlor-alkali industry, and this production technology has a history of more than 100 years. During the development of chlor-alkali production, electrodes such as platinum, magnetic iron oxide, carbon, and artificial graphite have been tried, but the use effect is not ideal. However, the use of precious metal mixed oxide coated titanium electrodes has many advantages. Titanium anode materials have strong chemical corrosion resistance, low chlorine overpotential, good electrical conductivity, high mechanical strength, easy processing, and low price. 1. Chlorine evolution potential, enhanced weight loss: 1.13v 2, polarization rate: 30mv 3, enhanced life: 3000min 4, enhanced weight loss: 10mg Performance: Initial chlorine evolution potential (saturated NaCl, C.D. = 3kA/m2): 1.10Vvs SCE. Lifespan 6 years, chlorine evolution potential (C.D. = 3kA/m2) is not greater than 1.172Vvs SCE during the guarantee period. Product geometry: plate type, various types of mesh type or other forms can be provided. Advantages: Can operate at higher current density; low anode potential; low energy consumption.
