Titanium Electrode Knowledge
Titanium electrode: Now briefly introduce the metal oxide coated titanium electrode, which has been used in many electrolysis industries since its inception. The titanium electrode was first invented by H. Beer in 1965.
Principle
Metal oxide coated titanium electrodes are distinguished according to the gas evolved from the anode in the electrochemical reaction. The chlorine evolution anode is used to precipitate chlorine on the anode, such as the ruthenium-coated titanium electrode; the oxygen precipitated on the anode is Oxygen anode, such as iridium-coated titanium electrode.
Advantage
After years of factory production and research, it has been discovered that compared with traditional graphite electrodes and lead-based alloy electrodes, the advantages of titanium electrodes are:
(1) The anode size is stable, and the distance between the electrodes does not change during the electrolysis process, which can ensure that the electrolysis operation is carried out under the condition of stable cell voltage;
(2) The working voltage is low, so the power consumption is small, and the DC power consumption can be reduced by 10%-20%.
(3) Titanium anodes have a long working life. In the production of chlorine by diaphragm method, metal anodes are resistant to chlorine and alkali corrosion. The anode life has reached more than 6A, while graphite anodes are only 8 months;
(4) It can overcome the problem of graphite anode and lead anode dissolution, avoid contamination of electrolyte and cathode products, and thus improve the purity of metal products.
(5) It can increase the current density.
(6) In the production of chlor-alkali, after the use of titanium anodes, the product quality is high, the purity of the chlorine gas is high, no CO2, and the alkali concentration is high, which can save heating steam and save energy consumption.
(7) Strong corrosion resistance.
(8) The short-circuit problem after deformation of the lead anode can be avoided, and the current efficiency can be improved.
(9) Titanium electrode is light in weight, which can reduce labor intensity.
(10) The shape is easy to make and can be made with high precision.
(11) The substrate can be used repeatedly
