Advantages and applications of various titanium anode plates
1. Ruthenium titanium anode plate
Product superiority
High current efficiency (chlorine evolution or oxygen evolution environment), excellent corrosion resistance, long electrode service life, electrode size can be designed according to user needs, electrode substrate can be reused many times, no pollution to the medium.
Application field
Chlor-alkali industry, sodium hypochlorite industry, sewage treatment industry, fresh water disinfection
2. Ruthenium iridium titanium anode plate
Product superiority
The anode size is stable, and the electrode spacing does not change during the electrolysis process, which can ensure that the electrolysis operation is carried out under the condition of stable cell voltage. The working voltage is low, the power consumption is small, and the consumption can be reduced by about 20%. The titanium anode has a long working life. In the chlorine gas production industry by the diaphragm method, the metal anode is resistant to chlorine and alkali corrosion. It can overcome the dissolution problem of graphite anode and lead anode, avoid the pollution of electrolyte and cathode products, and improve the quality of products. current density can be increased.
For example, in the production of chlor-alkali by the diaphragm method, the current density of the graphite electrode is 8A/M2; and the titanium anode can be doubled to 17A/M2;, so that in the electrolysis workshop and the same electrolytic cell, the output can be doubled. . It has strong corrosion resistance and can work in many electrolytic media with strong corrosiveness and special requirements. The short circuit problem after deformation of the lead anode can be avoided, thereby improving the current efficiency. The base titanium material can be used repeatedly.
Application field
Chlor-alkali industry, chlorine dioxide production, chlorate industry, hypochlorite industry, perchlorate production, hospital sewage treatment, persulfate production, food utensil disinfection, ionized water production
3. Tantalum iridium titanium anode plate
Product superiority
In the electrolytic extraction of metals in sulfuric acid solution, oxygen is released on the anode, so it is a very important issue to choose the appropriate anode material. Tantalum-iridium-coated titanium electrodes are used, which have low oxygen overpotential and are not corroded by electrolytes. The iridium oxide coating shows excellent electrolytic durability. The initial anode potential was 1.51V, and after 6000 hours, it was 1.64V, and the coating weight loss was 0mg/M2
Using lead-based alloy electrodes (containing Sb6% to 15%, or containing Ag1%) in electrolytic production, the lead anode will dissolve, consuming the anode material, affecting the life of the anode, and the lead dissolved in the solution will be on the cathode. Precipitation increases lead impurities in the metal and reduces product quality.
Ruthenium-based coating will be seriously damaged under this condition, so it should not be used. The initial anode potential was 1.48V, and after 1000 hours, it rose to 2.0V, and the anode had been passivated.
