Coated Titanium Gr1 Anode Sheet ，The full name of titanium anode is titanium-based metal oxide coated titanium anode (MMO). It uses titanium as the substrate, and brushes the precious metal coating on the titanium substrate to make it have good electrocatalytic activity and conductivity. In electrochemistry, there are two electrodes in an electrolytic cell, one is the cathode and the other is the anode. The titanium anode is one of such anodes.

Titanium anode classification

Distinguish according to the gas released from the anode in the electrochemical reaction, the chlorine anode that releases chlorine gas, such as ruthenium-based coated titanium electrode: the one that precipitates and oxidizes is called oxygen-evolving anode, such as iridium-based coated titanium electrode and platinum titanium mesh/plate .
Chlorine analysis anode (ruthenium-based coated titanium electrode): high chloride ion content in the electrolyte: generally in hydrochloric acid environment and electrolytic seawater, electrolytic saline environment. The corresponding products are: ruthenium iridium titanium anode, ruthenium iridium tin titanium anode.
Platinum-plated anode: Titanium as the base material. The surface is coated with precious metal platinum, and the thickness of the coating is generally 1-5um.
Oxygen evolution anode (iridium coated titanium electrode): The electrolyte is generally a sulfuric acid environment. The corresponding products are: iridium tantalum anode, iridium tantalum tin anode, high iridium anode.

The performance of titanium anode

1. The size of the anode 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, the power consumption is small, and the DC power consumption can be reduced by 10-20%.
3. Titanium anode has long working life and strong corrosion resistance.
4. It can overcome the dissolution problem of graphite anode and lead anode, and avoid the pollution of electrolyte and cathode products.
5. The current density is high, the overpotential is small, and the electrode catalytic activity is high, which can effectively capture high production efficiency.
6. In the production of chlor-alkali, titanium anode is used, the product quality is high, the purity of chlorine gas is high, it does not contain Co2, and the concentration of alkali is high, which can save steam for heating and energy consumption.
7. It can avoid the short circuit problem after the lead anode is deformed, and improve the current efficiency.
8. The shape is easy to make and can be made with high precision.
9. The titanium substrate can be reused.
10. Low overpotential characteristics, the air bubbles on the surface between the electrodes and the electrodes are easily removed, which can effectively reduce the voltage of the electrolytic cell.
