2, Ruthenium Iridium Titanium Anode Plate
The anode size is stable, and the electrode spacing does not change during the electrolysis process, which can ensure that the electrolysis operation is performed under the condition of stable cell voltage. The working voltage is low, the power consumption is small, and the consumption can be reduced by about 20%. Titanium anodes have a long working life. In the chlorine production industry by diaphragm method, metal anodes are resistant to corrosion by chlorine and alkali. It can overcome the dissolution problem of graphite anode and lead anode, avoid contamination of electrolyte and cathode products, and improve product quality. Can increase current density.
For example, in the production of chlor-alkali by the diaphragm method, the current density of the graphite electrode is 8A/M2; and the titanium anode can be doubled to 17A/M2; so that the output can be doubled in the case of the same electrolytic plant and electrolytic cell. . It has strong corrosion resistance and can work in many electrolytic media with strong corrosion and special requirements. It can avoid the short-circuit problem after the lead anode is deformed, thereby improving the current efficiency. The base titanium material can be used repeatedly.

3, Tantalum iridium titanium anode plate
The metal is electrolytically extracted in sulfuric acid solution, and oxygen is precipitated on the anode. It is a very important issue to choose the appropriate anode material. The use of tantalum-iridium-coated titanium electrode has low oxygen overpotential and is not corroded by electrolyte. The iridium oxide coating shows excellent electrolytic durability. The initial anode potential is 1.51V, after 6000 hours, it is 1.64V, and the coating weight loss is 0mg/M2
When using lead-based alloy electrodes (containing Sb6%-15%, or containing Ag1%) in electrolytic production, the lead anode will dissolve, consume the anode material, affect the life of the anode, and the lead dissolved in the solution will be on the cathode The precipitation increases the lead impurity in the metal and reduces the quality of the product.
Ruthenium-based coating will be severely damaged under this working condition, so it is not suitable for use. The initial anode potential was 1.48V. After 1000 hours, it rose to 2.0V, and the anode had been passivated.
