Advantages of the coated titanium anode

The electrolysis industries using metal anode include: chlor-alkali industry, aluminate production, water electrolysis, hospital sewage treatment, disinfection of domestic water and food appliances, industrial water treatment, steel plate galvanized chromium plating, electrodialysis desalination seawater, battery production, cathode protection, titanium fund oxide coating, etc.
1,Strong corrosion resistance, long working life- - - - - -can work in many electrolytic media with strong corrosion and special requirements; in chlor-alkali industrial production, the life of electrolytic cell with coated titanium anode (DSA) is 10 times that of graphite anode electrolytic cell.
2, The electrode is not dissolved- - - - - - -DSA is an insoluble electrode, which greatly avoids the contamination of the electrolyte and the bipolar product, so that the purity of the electrolytic product can be improved.
①Electrolysis machine using DSA (Pt coating), cathode product-drinkable alkaline electrolytic water does not contain heavy metal ions harmful to human body;
② In chlor-alkali production, after the use of DSA, the product quality, high chlorine purity, no CO2, high alkali concentration, can save heating steam, save energy consumption.
③ Electrolysis sewage treatment equipment adopts DSA to avoid the secondary pollution in the process of sewage treatment;
④ In the electroplating process, DSA is used to avoid the addition or attachment of heteroatoms on the surface of the processing workpiece, thus greatly improving the electroplating effect;
⑤ In the electroplating process, DSA is used to avoid the addition or attachment of heteroatoms on the surface of the processing workpiece, thus greatly improving the electroplating effect;
3,High current density.Titanium anode is more suitable for electrolysis at high working current density.
4,Low energy consumption, high production capacity- - - - - -DSA, the surface between electrodes and electrode bubbles are easy to eliminate, is an important reason for the reduction of DSA electrolytic cell voltage, DSA is used to improve the design concept and operating conditions of electrolytic cell structure, reduce the power consumption, accelerate the chemical reaction of the medium, thus increasing the production capacity. Titanium anode has also been widely used in many electrolytic industries.
5,DSA size stability- - - - - -lysis during the inter-electrode distance does not change, which can ensure the electrolysis operation in the trough voltage stability. The DSA electrolytic cell can avoid the short circuit problem after the deformation of the lead anode, so the current efficiency can be improved.
6,DSA light weight, can reduce the labor intensity.
7,Low operating voltage------The main reason of the low operating voltage of DSA：
① The overpotential of the active-coated titanium anode is relatively low for both chlorine and oxygen；
②The "bubble shielding effect" can be reduced. The bubbles generated on the surface of the metal anode are relatively small and detached quickly, etc. Therefore, the inflation degree between the electrodes is greatly reduced, the ohm drop between the two poles is about 700 mV, and the diameter of the bubble is about 3mm;
③ Reduce the resistance of the anode structure;
④ Shortens the interpolar distance.
Therefore, the energy consumption is small, can save the energy consumption, DC power consumption can be reduced by 10%~20%.
8,Base metal titanium can be used repeatedly。
Due to the advantages of titanium anode DSA, its development enables the electrolytic electrochemical industry to achieve great economic benefits, so it was soon promoted around the world, and the latest ionic membrane electrolysis technology can be designed and industrialized. Chlor-alkali production capacity, about 41 million tons / year worldwide, the use of titanium anode is not less than 70%, titanium anode is known as a major technology of chlor-alkali industry.
