The advantages and applications of various titanium anode plates: ruthenium-titanium anode plate, ruthenium-iridium titanium anode plate, tantalum-iridium titanium anode plate, iridium-tin titanium anode plate.
1, ruthenium-titanium anode plate
Product advantages: high current efficiency (chlorine or oxygen evolution environment), excellent corrosion resistance, long electrode life, electrode specifications and sizes can be designed according to user needs, electrode substrate can be reused many times, no pollution to the medium.
Application fields: chlor-alkali industry, sodium hypochlorite industry, sewage treatment industry, fresh water disinfection
2, ruthenium-iridium titanium anode plate
Advantages: The anode size is stable, the electrode spacing does not change during the electrolytic process, which can ensure that the electrolytic operation is carried out under the condition of stable tank voltage. Low working voltage, small power consumption, consumption can be reduced by about 20%. Titanium anodes have a long working life, and metal anodes are resistant to chlorine and alkali corrosion in the chlorine gas production industry by diaphragm method. It can overcome the problem of graphite anode and lead anode dissolution, avoid the pollution of electrolyte and cathode products, and improve the quality of products. Can improve the current density.
For example, in the production of chlor-alkali by diaphragm method, the current density of graphite electrode is 8A/M2; The titanium anode can be multiplied to 17A/M2; In this way, in the case of the same electrolytic plant and electrolyzer, the output can be doubled. Strong corrosion resistance, can work in many corrosive, have special requirements of electrolytic media. The short-circuit problem after lead anode deformation can be avoided, thus improving current efficiency. Matrix titanium can be used repeatedly.
Application fields: chlor-alkali industry, chlorine dioxide production, chlorate industry, hypochlorite industry, perchlorate production, hospital sewage treatment, persulfate production, food utensils disinfection, ionized water production
3. Titanium tantalum iridium anode plate
Advantages: Metal is extracted by electrolysis in sulfuric acid solution, oxygen is precipitated on the anode, and selecting the appropriate anode material is a very important problem. Titanium electrode coated with tantalum series has low oxygen overpotential and is not corroded by electrolyte. Iridium oxide coatings show excellent electrolytic durability. The initial anode potential is 1.51V, and after 6000 hours, it is 1.64V, and the coating weight loss is 0mg/M2
The use of lead-based alloy electrodes in electrolytic production (containing Sb6% ~ 15%, or containing Ag1%), the lead anode will dissolve, consume the anode material, affect the life of the anode, and the lead dissolved in the solution will precipitate on the cathode to increase the lead impurities in the metal, reducing the quality of the product. Ruthenium coating will be seriously damaged under this condition, so it is not suitable for use. The initial anode potential was 1.48V, and 1000 hours later, it rose to 2.0V, and the anode had been passivated.
Applications: electrolytic production of non-ferrous metals, disinfection of food utensils, electrolytic silver catalyst production, dyeing and finishing wastewater treatment of woolen mills, electrolysis manufacturing of copper foil, galvanized steel plate, chrome plating, electrolytic oxidation recovery of mercury, rhodium plating, palladium plating, gold plating, water electrolysis, salt melting electrolysis, battery production, cathode protection, ionized water production, printed circuit board,
4, iridium tin titanium anode plate
Product advantages: high current efficiency (in chlorine or oxygen evolution environment), excellent corrosion resistance, long service life of the electrode, the size of the electrode can be designed according to user needs, the electrode substrate can be reused many times, no pollution to the medium.
Application fields: chlor-alkali industry, aluminum foil, copper foil industry, industrial sewage treatment, ionized water production, organic electrochemical treatment and organic electrochemical synthesis, electrolytic purification treatment gas, seawater desalination, oxidant regeneration cycle.
