Titanium anode function and superiority
Titanium Anodes for Electroplating The insoluble anodes are coated with a noble metal oxide coating having high electrochemical catalytic properties on a titanium substrate (titanium mesh, titanium plate, titanium strip, titanium tube, etc.), the coating contains a highly stable valve Metal oxide. The new insoluble titanium anode with high electrochemical catalytic energy, oxygen evolution overpotential lower than the lead alloy insoluble anode about 0.5 V, significant energy savings, high stability, does not pollute the bath, lightweight, easy to replace. The oxygen evolution potential of the original insoluble titanium anodes is also lower than that of the platinum-insoluble anode, but their lifetime is more than doubled. Widely used in various electroplating as anodes or auxiliary anodes, can replace the conventional lead-based alloy anode, under the same conditions, can reduce the tank voltage, saving energy consumption; insoluble titanium anode in the plating process has good stability (Chemical, electrochemical), long service life. This anode is commonly used in nickel-plated gold, chrome, zinc, copper and other non-ferrous metal plating industry.
The role of the metal oxide coating on the titanium anode is low resistivity, good electrical conductivity, stable chemical composition of the noble metal coating, stable crystal structure, stable electrode size, good corrosion resistance, long life, good Electrocatalytic properties, help to reduce oxygen evolution, chlorine reaction over-potential, saving energy.
Titanium electrodes have the following advantages:
1. The anode size is stable. The distance between the electrodes in the process of electrolysis does not change, which can ensure that the electrolysis operation is carried out under the condition that the cell voltage is stable.
2. Working voltage is low, so the power consumption is small, can save energy consumption. DC power consumption can be reduced by 10% to 20%.
3. Titanium anode prolonged working life, the diaphragm production of chlorine industry, the metal anode resistance to chlorine and alkali corrosion, anode life has reached 6 years, while the graphite anode is only 8 months.
4. To overcome the graphite anode and lead anode dissolution problems, to avoid contamination of the electrolyte and cathode products, which can improve the purity of metal products.
5. Can improve the current density. Titanium anodes are suitable for electrolysis at high operating current densities.
6. Chlor-alkali production, the use of titanium anode, the product of high quality, high purity chlorine, non-CO2, alkali concentration, saving energy consumption.
7. Corrosion resistance, can be full of corrosive, special requirements of the electrolytic medium to work.
8. Avoid lead short circuit after the deformation of the anode, which can improve the present efficiency.
9. Titanium anode lightweight, can reduce labor intensity.
10. The use of metal anodes, chlorate electrolyzer high temperature, high current density operation possible.
11. Low over-potential characteristics, easy to exclude the surface of the electrode and the bubbles in the electrode, the metal anode cell voltage reduction is a major reason.
Titanium anode is mainly used in electrochemistry and electrometallurgical two major industrial sectors. The use of metal anodes electrolysis industry are: chlor-alkali industry, aluminate production, water electrolysis, hospital sewage treatment, disinfection of domestic water and food utensils, industrial water treatment, galvanized steel chrome ruthenium plating, electrodialysis desalination seawater, batteries Production, cathodic protection, titanium-based metal oxide coating and more. Applications involving chemical, metallurgical, water treatment, environmental protection, electroplating, electrolytic organic synthesis and other industries.
