The chemical industry of producing chlorine gas and caustic soda by electrolyzing saturated salt aqueous solution is called chlor-alkali industry, which has a history of more than 100 years. In the process of chlor-alkali production and development, platinum, magnetic iron oxide, carbon, artificial graphite and other electrodes have been tried, but the use effect is not ideal. However, the use of noble metal mixed oxide coated titanium electrode has many advantages. Titanium anode material has strong chemical corrosion resistance, low chlorine overpotential, good electrical conductivity, high mechanical strength, easy processing, cheap and so on.
1、 chlorine evolution potential enhanced weight loss :1.13v
2. polarization: 30mv
3、 strengthening life :3000min
4、enhanced weight loss :10mg
Performance:
Initial chlorine evolution potential (saturated NaCl, C.D.=3kA/m2) : 1.10Vvs SCE. Life of 6 years, within the guaranteed period of chlorine evolution potential (C.D.=3kA/m2) is not more than 1.172Vvs SCE, product geometry can provide plate, various types of mesh or other forms.
Advantages: can operate at a high current density, low anode potential, low energy consumption.
