MMO Electrode Hydrogen electrolysis is the process of using electricity to break down water into hydrogen (H 2 ) and oxygen (O 2 ).MMO coated titanium anodes are the anode portion of hydrogen electrolysis. MMO-coated titanium anodes are also known as dimensionally stable anodes, where MMO is an acronym for mixed metal oxide. MMO coated titanium anodes have a longer service life than conventional anodes. Its mixed metal oxide coating protects the titanium anode from corrosion and extends its service life. In addition, the coating increases the surface area of the anode, which improves reaction efficiency and ensures efficient operation over time. This allows the use of higher current densities and lower operating voltages, thereby reducing energy consumption and operating costs. Overall, MMO-coated titanium anodes are an efficient option, especially for hydrogen production processes. It is suitable for a wide range of environments, including seawater, brackish water, fresh water, carbon backfill, concrete, sand and soil.
Product Introduction Metal-coated titanium electrodes, also known as metal anodes, are also called MMO (Mixed Metal Oxide) titanium anodes or DSA (Dimensionally Stable Anode) anodes, which are dimensionally and shape-stable anodes. According to the different coating metals, it is generally divided into: ruthenium-iridium titanium anode, iridium-tantalum titanium anode and platinum-coated titanium anode. Metal-coated titanium electrodes use GR1 titanium as the base material (wire, rod, tube, plate, net) to brush the precious metal coating on the titanium substrate, so that it has good electrocatalytic activity, electrical conductivity and oxidation resistance. Widely used in electrolysis, electroplating, sanitation and disinfection, cathodic protection and other fields. Product parameters Base material: GR1 Coating composition: metal ruthenium-iridium, iridium-tantalum, platinum Working current range:

The graphite electrode comprises: (1) Regular power graphite electrode( RP grade Graphite Electrode) . Graphite electrode with current density less than 17a / cm2 is allowed to be used in common power electric furnaces for steelmaking, silicon smelting and yellow phosphorus smelting. (2) Oxidation resistant coating graphite electrode. A graphite electrode coated with an anti-oxidation protective layer (graphite electrode anti oxidant). The formation of both conductive and high temperature oxidation resistant protective layer can reduce the electrode consumption (19% ~ 50%), prolong the service life of the electrode (22% ~ 60%), and reduce the electric energy consumption of the electrode. The popularization and application of this technology can bring such economic and social effects as follows: 1. The unit consumption of graphite electrode is less, and the production cost is reduced to a certain extent. For example, according to the consumption of 35 graphite electrodes per week and 165 refining heats of LF refining furnace in a steel-making plant without shutdown in the whole year, 373 (153 tons) electrodes can be saved every year by using graphite electrode oxidation resistance technology, and RMB 2585700 can be saved by RMB 16900 per ton of ultra-high power electrode per year. 2 The graphite electrode consumes less electricity, saves the unit electricity consumption of steelmaking, saves the production cost, saves energy! 3. Because the graphite electrode is replaced less times, the labor amount and risk coefficient of operators are reduced, and the production efficiency is improved. 4 Graphite electrode is a high consumption and high pollution product, which has a very important social significance in the days of promoting energy conservation, emission reduction and environmental protection. This technology is still in the stage of research and development in China, and some domestic manufacturers have begun to produce it. It is widely used in Japan and other developed countries. At present, there are also companies that import the anti-oxidation protective coating in China. (3) High power graphite electrode (HP grade Graphite Electrode). Graphite electrode with current density of 18-25a / cm2 is allowed to be used in high power electric arc furnace for steelmaking. (4) Ultra high power graphite electrode( UHP grade Graphite Electrode). Graphite electrode with current density greater than 25A / cm2 is allowed. It is mainly used in ultra high power EAF.
