The titanium anode is the anode in the titanium based metal oxide coating

- Sep 19, 2017-

The titanium anode is the anode in the titanium-based metal oxide coating. According to its surface catalytic coating with different oxygen function, chlorine function. In general, the electrode material has good electrical conductivity, small pitch change, strong corrosion resistance, good mechanical strength and processing performance, long life, low cost and good electrocatalytic performance for electrode reaction. At present, titanium is the most satisfying Comprehensive requirements of the metal, the general use of industrial titanium TA1 \ TA2.

Titanium anode metal oxide coating role is: low resistivity, with good conductivity (titanium itself, poor conductivity), precious metal coating chemical composition is stable, crystal structure is stable, the electrode size is stable, corrosion resistance Good, long life, with good electrocatalytic performance, is conducive to reducing the oxygen, chlorine reaction over-potential, saving energy.

1, titanium anode long life, diaphragm production of chlor-alkali industry, the metal anode resistance to chlorine and alkali corrosion, anode life has been more than 6 years, while the graphite anode only 8 months.

2, can overcome the graphite anode and lead anodic dissolution problems, to avoid the electrolyte and cathode products pollution, which can improve the purity of metal products.

3, can increase the current density. Diaphragm production of chlor-alkali, the graphite anode current density of 8A / dm2, titanium anode can be doubled to increase, up to 17A / dm2, so in the electrolysis plant, electrolyzer under the same conditions, the output can be increased by 1 times, Single tank production capacity, effectively improve the labor productivity. In the high operating current density for electrolysis, the use of titanium anode is more appropriate.

4, due to the use of metal anode, chlorate electrolytic cell high temperature, high current density operation possible. The use of metal anodes to improve the structure of the electrolyzer, reducing the power consumption, speed up the hypochlorite chlorite chemical reaction, thereby improving the production performance.
