Advantages of Iridium tantalum titanium anode
Advantages of Iridium tantalum titanium anode
After years of factory production and research, compared with the traditional graphite electrode and lead-based alloy electrode, the advantages of titanium electrode are:
1. Low working power, so small power consumption, DC power consumption can be reduced by 10%-20%.
2. Can improve the current density.
3. Strong corrosion resistance.
4. The short-circuit problem after deformation of lead anode can be avoided, thus improving the current efficiency.
5 titanium electrode light weight, can reduce labor intensity.
6. The shape is easy to make and can be high-precision.
7. Matrix can be used repeatedly
8. The anode size is stable, the distance between electrodes does not change during the electrolytic process, which can ensure that the electrolytic operation is carried out under the condition of stable tank voltage;
9. In chlor-alkali production, after using titanium anode, the product quality is high, chlorine gas purity is high, no CO2, high alkali concentration, can save heating steam, save energy consumption.
10 titanium anode long working life, diaphragm production of chlorine gas industry, metal anode resistance to chlorine and alkali corrosion, anode life has reached more than 6A, and graphite anode only 8 months;
11. It can overcome the dissolution of graphite anode and lead anode, avoid the pollution of electrolyte and cathode products, and thus improve the purity of metal products.
Precautions for using iridium tantalum titanium anode
Precautions for using iridium tantalum titanium anode
(1) It should not be soaked in solution for a long time in power mode when stopping, and it is best to load a small current of about 5a to protect the plate.
(2) The electrolyte working temperature should not be too high, the ideal temperature of 25-40℃, if conditions can be added heat exchanger to maintain the best electrode environment.
(3) The titanium electrode has a black surface after oxidation and sintering. The uncoated surface is blue and does not have electrode performance. The black side corresponds to the cathode.
(4) electrolyte to maintain stability, especially can not contain cyanide ions and fluoride ions, these impurities will seriously corrosion titanium matrix; The service life of anode is affected.
(5) When electrolytic recovery of copper, nickel, gold, silver, cobalt and other metals, the cathode attachment shall not be too thick, in order to prevent the pole spacing is too small or metal spines caused by short circuit breakdown of anode and cathode. Regular slot cleaning is required.
(6) Avoid reverse electrode use. Once the noble metal oxide coating is used as the cathode, the surface will produce reduction reaction, which is easy to change into metal elemental, and it cannot effectively combine with the titanium base, resulting in the coating falling off.
(7) The normal working current density is less than 2000a/m2. If the current is too large, the reaction is too intense, the coating falls off, and the anode life is shortened.
(8) Before the electrolyte enters the electrolytic cell, a filter device shall be added, which shall not contain metal particles with a diameter greater than 0.1mm to prevent excessive aggregation and short circuit of anode and cathode. Shielding anode performance. If the plate appears scaling, need to use dilute hydrochloric acid cleaning, not scrub.
(9) The anode has life, to ensure the stability of production is more beneficial to prolong the service cycle. If the anode coating falls off, repair the coating in time to prevent the tank voltage from being too high.
(10) Once the titanium electrode substrate is pickled, all the subsequent production and processing processes and use processes must be carried out strictly and carefully. When moving, wear clean gloves to jam both ends or edges of the anode. It is best to contact the uncoated part, and any foreign body scratch is strictly prohibited on the coating surface. Installation and handling should be careful. The surface of the coating should not be scratched, otherwise it will soon be partially corroded
