Classification of titanium anodes

According to the anode precipitates gas in the electrochemical reaction to distinguish, the precipitation of chlorine gas is called chlorine evolution anode, such as ruthenium coating titanium electrode; the precipitation of oxygen is called oxygen evolution anodes, such as iridium coating titanium electrode and platinum titanium mesh/plate.

1, chlorine anode (ruthenium coating titanium pole): the content of chloride in the electrolyte is high, generally in the environment of hydrochloric acid and electrolytic seawater, electrolytic saltwater environment.

2, oxygen evolution anode (Iridium coating titanium electrode): electrolyte is generally sulfuric acid environment.

3, platinum-plated anode: on the surface of titanium substrate plated precious metal platinum, coating thickness is generally 0.2-5um, and platinum-titanium electrode mesh is generally 12.5×4.5mm or 6×3.5mm.

Advantage

Compared with the traditional graphite electrode, lead-based alloy electrode, titanium coated ruthenium electrode shows unparalleled performance:

(1) the anode size is stable, and the distance between electrodes does not change in the process of electrolysis, which can ensure that the electrolytic operation is carried out under the condition of stable cell voltage;

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

(3) Long working life, diaphragm method in the production of chlorine industry, metal anode resistance to chlorine and alkali corrosion, anode life has reached more than 6A, and graphite anode only 8 months;

(4) can overcome the graphite anode and lead anode dissolution problem, avoid the contamination of electrolyte and cathode products, and can improve the purity of metal products;

(5) can improve the current density;

(6) In the production of Chlor-alkali, the use of titanium coated ruthenium electrode, the product quality is high, the purity of chlorine is high, does not contain CO2, the concentration of alkali is high, can save heating steam, save energy consumption;

(7) Strong corrosion resistance;

(8) the short-circuit problem after lead anode deformation can be avoided so that the current efficiency can be improved;

(9) Titanium electrodes are lightweight, and can reduce the labor intensity;

(10) shape production is accessible and high precision.

(11) The matrix can be used repeatedly.
