Titanium electrodes are anodes that are coated with a layer of oxide coating on atitanium.html> titanium substrate. The commonly used substrates are grade 1, grade 2 and other materials. It is not an ordinary metal material, but a professional field of electrochemical corrosion and protection. Therefore, when choosing a manufacturer of titanium electrodes, you should pay attention to whether the main scope is electrochemical electrodes, not titanium materials or metal materials.

There are many types of coatings for titanium electrodes, such as binary, ternary or multi-element coating systems such as ruthenium-iridium coating, iridium-tantalum coating, lead dioxide, platinum coating, etc. Titanium electrodes were first used in the chlor-alkali industry. Later, as the DSA electrode material technology matured, it was also used in other electrochemical fields.

1. Such as electrochemical water treatment, electrodeposition of non-ferrous metals, electroplating, impressed current cathodic protection, organic synthesis and other electrochemical fields. Among them, ruthenium-iridium coated titanium electrodes are widely used in industrial wastewater treatment, such as degrading COD, ammonia nitrogen, total nitrogen, nitrate nitrogen, etc., and the removal effect is relatively obvious.

2. Iridium-tantalum coating | The application of ruthenium-iridium coating titanium anode in electrolytic extraction of non-ferrous metals requires that the selected anode should be corrosion-resistant, have good stability, can be used for a long time, and have good electrocatalytic properties to reduce the anode reaction. process potential and cell voltage. At present, multi-component mixed ruthenium-based, iridium-based, and platinum-based coated titanium anodes have been widely used in domestic electrodeposition to extract metals.

3. In the electroplating industry, the use of coated titanium electrodes can keep the plating solution stable. It is an electrode material with good acid corrosion resistance, especially in gold plating, copper plating, chromium plating, and rhodium plating applications. It shows good performance.

4. Noble metal-coated titanium electrode. The impressed current cathodic protection method is a method that uses applied current to effectively protect metals from corrosion. At present, the titanium anode technology produced by Shaanxi Youchuang Environmental Protection Technology has reached more than 50-70 years. And it can adapt to various environments such as sea water, fresh water, soil, desert and so on. According to different design shapes, it can be divided into MMO anode strips, MMO tubular anodes, MMO gang anodes, flexible anodes, expanded mesh anodes, etc.

5. Oxidation pattern-coated titanium anodes also have good application prospects in other electrochemical fields. Such as ionized water machines, hydrogen-rich cups, sterilizing washing machines, fruit and vegetable sterilizers, household portable sterilizers, etc., can be used as disinfection electrode materials to achieve the effect of electrolytic disinfection.

Ruthenium Iridium Titanium Electrode/Ruthenium Titanium Mesh Electrode Ti-Ru-Ir Mixed Oxide Coated Anode

Metal oxide-coated titanium electrodes are distinguished according to the gas released from the anode during the electrochemical reaction. Those used for the precipitation on the anode are called chlorine-evolving anodes, such as ruthenium-based coated titanium electrodes; those used for the precipitation of oxygen on the anode are called oxygen-evolving anodes. Anode, such as iridium-coated titanium electrode.

Compared with traditional graphite electrodes and lead-based alloy electrodes, titanium-coated ruthenium electrodes show excellent performance:

1) The size of the anode is stable, the distance between the electrodes does not change during the electrolysis process, and the electrolysis operation can be carried out when the cell voltage is stable;

(2) The working voltage is low, so the power consumption is small, and the DC power consumption can be reduced by 10%---20%;

(3) Long working life. In the diaphragm production industry, metal anodes are resistant to chlorine and alkali corrosion. The anode life has reached more than 6A, while the graphite anode is only 8 months;

(4) It can overcome the dissolution problems of graphite anodes and lead anodes and avoid contamination of electrolyte and cathode products, thus improving the purity of metal products;

(5) Can increase current density;

(6) In chlor-alkali production, after using titanium-coated ruthenium electrodes, the product has high quality, high purity, no CO2, and high alkali concentration, which can save heating steam and energy consumption;

(7) strong sex;

(8) It can avoid the short circuit problem after the lead anode is deformed, thus improving the current efficiency;

(9) Titanium electrodes are light in weight and can reduce labor intensity;

(10) The shape is easy to make and can be transformed;

(11) The matrix can be used repeatedly.
