Advantages of Ruthenium-IridiumTitanium anode:

(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 performed under the condition that the cell voltage is stable;

(2) The working voltage is low, so the power consumption is small, and the DC power consumption can be reduced by 10% - 20%;

(3) Long working life;

(4) It can overcome the problem of dissolution of graphite anode and lead anode, avoiding contamination of electrolyte and cathode products, and thus improving the purity of metal products;

(5) can increase the current density;

(6) In the production of chlor-alkali, after the titanium-coated ruthenium electrode, the product quality is high, the chlorine gas has high purity, does not contain CO2, and the alkali concentration is high, which can save steam for heating and save energy consumption;

(7) Strong corrosion resistance;

(8) The short circuit problem after the deformation of the lead anode can be avoided, thereby improving the current efficiency;

(9) The titanium electrode is light in weight and can reduce labor intensity;
