Advantages and Applications of Titanium Anode Plate

1. Ruthenium-titanium anode plate

Advantage: High current efficiency (Chlorine extraction or oxygen evolution environment), excellent corrosion resistance, long electrode life, electrode size can be designed according to user’s requirements, electrode substrate can be reused many times, no medium pollution.

Application: Chlor-alkali industry, sodium hypochlorite industry, wastewater treatment industry, fresh water disinfection

2. Ruthenium-iridium titanium anode plate

Advantage: The titanium anode does not change the electrode spacing during the electrolysis process, which can ensure the electrolysis operation is carried out under the condition of stable cell voltage. Low working voltage, minimal power usage, and a 20% reduction in consumption are all advantages. Titanium anodes have a long working life, diaphragm cell electrolysis process in chlor-alkali industry, metal anodes are resistant to chlorine and alkali corrosion. It can solve the lead and graphite anode dissolution issue, prevent electrolyte and cathode product pollution, enhance product quality, and boost current density. 

For example, in the diaphragm method of producing chlor-alkali, the current density of the graphite electrode is 8A/㎡; and titanium anodes can be multiplied to 17A/㎡; In this way, the output of the same electrolysis plant and electrolyze can be doubled. It has strong corrosion resistance and can work in many electrolytic media with strong corrosion and special requirements. Preventing short circuits after lead anode deformation and thus increasing current efficiency, and the titanium substrate can be used repeatly

Application: Chlor-alkali industry, Chlorine dioxide production, Chlorate industry, Hypochlorite industry, Perchlorate production, hospital sewage treatment, Persulfate production, food utensils disinfection, Ionized water production.

3. Tantalum-iridium titanium anode plate

Advantage: Electrolysis extracts metal from a sulfuric acid solution and oxygen from the anode. It is critical to choose appropriate anode materials. Titanium electrode coated with tantalum iridium series, with low oxygen overpotential and no electrolyte corrosion. Iridium oxide coatings are extremely electrolytically durable. The anode potential was 1.51V at the start and 1.64V after 6000 hours, with a coating weight loss of 0mg/㎡.

When lead-based alloy electrodes (containing Sb6%-15% or Ag1%) are used in electrolytic production, the lead anode dissolves, consumes the anode material, and reduces the anode’s service life, and the lead dissolved in the solution can be separated out on the negative electrode, increasing the lead impurity in the metal and lowering product quality. Ruthenium-based coatings will be severely damaged under this working condition, so they are not suitable for use. After 1000 hours, the initial anode potential was 1.48V, and it rose to 2.0V, then anode had been passivated.

Application: Electrolytic production of non-ferrous metals, disinfection of food utensils, production of electrolytic silver catalysts, wastewater treatment in woolen mills, electrolytic of copper foil, galvanized and chromed steel plates, recovery of mercury by electrolytic oxidation, rhodium plating, palladium plating, gold plating, water electrolysis, molten salt electrolysis, battery production, cathodic protection, ionized water production, printed circuit boards.
