Platinum Titanium Electrode
Detailed explanation of titanium anode
What is a titanium anode? The titanium anode is called a titanium-based metal oxide coated titanium anode (MMO). Also called KSA anode. (Dimensional shape stable anode). It uses titanium as the substrate and brushes the precious metal coating on the titanium substrate to make it have good electrocatalytic activity and electrical conductivity. Titanium anode classification: According to the anodic precipitation gas in the electrochemical reaction, the chlorine anode is separated, such as the lanthanide coated titanium electrode: the oxidized anode is called the oxygen evolution anode, such as the lanthanide coated titanium electrode and platinum. Titanium mesh / board. Chlorine anode (tantalum coating titanium electrode): high chloride ion content in the electrolyte: generally in the hydrochloric acid environment and electrolyzed seawater, electrolyzed brine environment. Corresponding to our company's products are Ru-Ir Titanium anode, bismuth tin titanium anode. Oxygen evolution anode (lanthanide coated titanium electrode): The electrolyte is generally in a sulfuric acid environment. Corresponding to our company's products are It-Ta anode, bismuth tin anode, high Ir-anode. Platinum-plated anode (platinum titanium mesh/platinum titanium plate): titanium is the substrate. The surface is plated with precious metal platinum, and the thickness of the coating is generally 1-5 um (micrometers). Platinum titanium mesh mesh specifications are generally 12.7 * 4.5mm or 6 * 3.5mm. Anode selection: If the customer does not know what anode to use, we need the customer to provide the anode working environment and medium: 1. Current density per square meter. (The intensity of the current carried by a single anode divided by the surface area of the electrode) 2. Temperature. 3. PH value. 4. The composition and proportion of the solution. 5. Products or uses produced. What is the role of the metal oxide coating on the titanium anode? By covering different coatings, the electrical conductivity and electrocatalytic activity are enhanced, the electrolysis reaction process is promoted, and the service life of the anode in different use environments is prolonged to achieve the intended use effect. Thickness of metal oxide coating on titanium anode: The electrocatalytic reaction is mainly the precious metal in the coating. Only the precious metal content can meet the requirements of use to ensure the normal operation of the anode product. The thickness is only an appearance, which is mainly determined by the number of passes of the brush and the concentration of the solvent, and the content of the precious metal. How much is not directly related, too thick coating is more likely to fall off. What is anode passivation? What is the passivation phenomenon of metal? When the wire is immersed in dilute nitric acid, the wire will dissolve quickly, but when the wire is placed in concentrated nitric acid, the dissolution of the wire is almost completely stopped. At this time, if the wire is replayed back In dilute nitric acid, the iron wire is no longer dissolved. It is impossible to see what changes the surface of the wire with the naked eye or even with a microscope. It is considered that the wire is in a passivated state at this time.
The advantages of our product is as below:
1. The anode size is stable, and the distance between the electrodes does not change during the point solution process, which ensures that the electrolysis operation is performed under stable tank voltage. 2. The working voltage is low, so the power consumption is small, the power consumption can be saved, and the DC power consumption can be reduced by 10% to 20%. 3. The working life of titanium anode is long. In the chlorine gas industry produced by diaphragm method, the metal anode is resistant to chlorine and alkali corrosion. The anode life has been more than 6 years, while the graphite anode is only 8 months. 4. It can overcome the problem of dissolution of graphite anode and lead anode, avoiding pollution of point solution and cathode product, thus improving the purity of metal products. 5. Increase current density. When electrolysis is carried out at a high working current density, it is preferred to use a titanium anode. 6. In the production of chlor-alkali, after using titanium anode, the product quality is high, the purity of chlorine gas is high, it does not contain co2, the alkali concentration is high, and energy consumption is saved. 7. It is highly resistant to corrosion and can work in many corrosive and special electrolytic media. 8. Avoid the short circuit problem after the lead anode is deformed, thus improving the current efficiency. 9. Titanium anodes are light in weight and reduce labor intensity. 10. With metal anodes, high temperature, high current density operation of the chlorate bath is possible. 11. Low overpotential characteristics, the bubbles between the electrodes and the electrodes are easily eliminated, which is an important reason for the voltage drop of the metal anode electrolytic cell. Main use: Titanium anodes are mainly used in the two industrial sectors of electrochemistry and electro-metallurgy. Electrolytic industries using metal anodes include: chlor-alkali industry, aluminate production, water electrolysis, hospital sewage treatment, domestic water and food utensils disinfection, industrial water treatment, steel plate galvanized chrome plating, electrodialysis desalination, seawater, batteries Production, cathodic protection, titanium-based metal oxide coatings, etc. Applications include chemical, metallurgical, water treatment, environmental protection, electroplating, electrolytic organic synthesis and other industries. The platinum-iridium coated titanium anode is insoluble anode, and the platinum-iridium coating is firmly bonded to the titanium substrate. The utility model has the advantages that it is extremely stable and corrosion resistant and can be used for various media; for the oxygen discharge reaction, the overpotential is high, and for the hydrogen release reaction, the overpotential is low; and the chlorine evolution efficiency during electrolysis is better improved.
