Tantalum iridium coated titanium plate products
Oxygen-resistant anode, mainly used in oxygenation reaction, especially for acidic electrolytes, such as a certain concentration of sulfuric acid electrolyte, oxygen ultra-low, can be used for oxygen electrolysis, but also chlorine corrosion, available Electrolysis in oxygen and oxygenation, such as seawater electrolysis, etc. It is an oxygen material with better oxygen evolution. The electrode material available in this environment is restricted. The coating electrode has been applied to organic electrolysis, such as cysteine, glyoxaline acid, succinic acid, etc., can be used for organic electrolysis indirect oxidation of Cr3 ++ → Cr6 + electrolysis, sewage treatment for the oxidation of organic and toxic substances in water, Such as CN- conversion. Also in the electroplating industry, as auxiliary electrodes, such as the auxiliary anode for plating Cr, the auxiliary anode for electrolytic copper, the auxiliary anode for electrolytic zinc, the auxiliary anode for cathodic protection, and so on. Ruthenium - iridium - titanium ternary coating anode the coating anode for high hydrogen peroxide electrolyte, oxygen corrosion, suitable for ion - exchange membrane electrolysis. Coating Index:
1, the discharge potential for 4000A / m2 current density of 1.18 volts (S.C.E). 2, enhanced life (coating weight loss method) 1.02mm / 4 hours. (Ru-Ir-Sn-Ti) quaternary coating electrode. Ruthenium-iridium-tin-titanium (Ru-Ir-Sn-Ti) quaternary coating electrode is employed to industrial applications. 1, low chlorine potential, over-potential is small, 2000A / m2 current density of chlorine discharge potential is not greater than 1.12V, over-potential is less than 20mv. 2, the polarization rate is less than 30mv / 10 unit current densities.
Www.hongsenti.cn 3, enhanced life long 0.5N H2SO4, 1A / cm2 current density, life expectancy is greater than 1500 minutes. The above three indicators are better than industry-specific indicators (industry indicators: potential 1.13 volts, polarization
Rate 40mv / 10 unit current densities, enhanced life of more than 1000 minutes). . The coating has been extensively used in chlor-alkali industry, the actual service life of up to 8 years. Titanium-based PbO2 anode The anode is based on titanium mesh, the above plating β-PbO2, which is characterized by high oxygen, can be used in acidic solutions, especially some organic electrolysis, anodic oxidation requires high potential, but also Minimize the oxygen side effects, PbO2 electrode is a better material. Such as perchlorate electrolysis, sewage treatment of organic matter, such as phenol-containing wastewater. It can also be used as a general oxygen electrode, although its oxygen is extremely prohibitive, but its price is much cheaper than the Ta-Ir electrode, so in organic electrolysis, electroplating, sewage treatment and other applications.
