![]() ![]() The more such oxides, the more active centers, and the better the activity of the ruthenium, iridium, titanium anode. The non-stoichiometric oxide is the real active center of chlorine discharge. The active coating is composed of non-stoichiometric RuO2- and TiO2, which is an oxygen-deficient oxide. The titanium substrate is pre-oxidized to form a layer of oxide film, which can increase the binding force of the active coating of ruthenium, iridium, titanium and the titanium substrate, make the coating firm, prevent ruthenium from falling off and dissolving, but also cause ruthenium, iridium, titanium Increase in anode ohmic drop. When the total current density of electrolysis increases, the increase in the rate of chlorine generation is much greater than the increase in the rate of oxygen generation, so the increase in current density is conducive to the decrease of the oxygen content in chlorine. Reduce the generation of oxygen, which can slow down the formation of oxide film. (Divided into crushed peeling, belly-shaped layer peeling and cracked peeling) To a certain extent, the titanium ruthenium iridium titanium anode is useless. If the coating and the substrate are not firmly bonded, they will fall off the titanium plate substrate and fall off. The electrochemical reaction is only the ruthenium iridium titanium active coating. ![]() The titanium ruthenium iridium titanium anode is composed of a titanium substrate and a ruthenium iridium titanium active coating. There are several reasons for the passivation of ruthenium iridium titanium anode: This phenomenon is called anode passivation. When the voltage rises very high and there is actually no current through, the ruthenium-iridium-titanium anode loses its function. Ruthenium, iridium, titanium anode has a certain working life during the electrolysis process. The surface is coated with platinum, the thickness of the coating is generally 0.5-5μm, and the size of the platinum and titanium mesh is generally 12.5×4.5mm or 6×3.5mm. Platinum-coated anode: Titanium is the base material. The corresponding products of our company are iridium tantalum anode, iridium tantalum tin titanium anode, and high iridium titanium anode.ģ. Oxygen evolution anode (iridium-coated titanium electrode): The electrolyte is generally a sulfuric acid environment. Corresponding products of our company are ruthenium iridium titanium anode, ruthenium iridium tin titanium anode.Ģ. Chlorine evolution anode (ruthenium-coated titanium electrode): The electrolyte contains a high content of chloride ions, generally in the environment of hydrochloric acid, electrolysis of sea water and salt water. The chlorine evolution anode is called the chlorine evolution anode, such as ruthenium-coated titanium electrode: the oxygen evolution anode is called the oxygen evolution anode, such as iridium-coated titanium electrode and platinum titanium mesh. It is distinguished according to the gas evolved in the anode during the electrochemical reaction. Titanium electrodes are currently used in Japan, the United States, Germany, and China, which not only greatly saves electroplating energy consumption, but also creates conditions for the production of thick galvanized and tin steel plates because it can increase the electroplating current density.ġ. It will be an inevitable trend in the development of electro-galvanized and tin production at home and abroad. ![]() It can work stably for more than 4000 hours and has low cost. Titanium anode has excellent electrical conductivity and corrosion resistance, and its service life is much longer than that of lead anode.
