Advantages and Applications of Titanium Anode Plate
The advantages and applications of various titanium-anode.html>titanium anode plates: nailed titanium anode plates, nailed iridium titanium anode plates, tantalum iridium titanium anode plates, and iridium tin titanium anode plates.
1. Nail titanium anode plate
Product advantages: high current efficiency (chlorine evolution 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 base can be reused many times, and does not pollute the medium. .
Application areas: chlor-alkali industry, sodium hypochlorite industry, sewage treatment industry, fresh water disinfection
2. Nail iridium titanium anode plate
Product advantages: The size of the anode is stable, and the electrode spacing does not change during the electrolysis process, which ensures 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 power consumption can be reduced by about 20%. Titanium anodes have a long working life. In the chlorine production industry using the diaphragm method, metal anodes are resistant to chlorine and alkali corrosion. It can overcome the dissolution problems of graphite anodes and lead anodes, avoid contamination of electrolytes and anode products, improve product quality, and increase current density.
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. In this way, in the case of the same electrolytic plant and electrolytic cells, the output can be doubled. . It has strong corrosion resistance and can work in many electrolytic media that are highly corrosive and have special requirements. It can avoid the short circuit problem after the lead anode is deformed, thereby improving the current efficiency. The base titanium material can be used repeatedly.
Application areas: 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 advantages: Metals are extracted electrolytically in sulfuric acid solution, and oxygen is precipitated on the anode. Choosing the appropriate anode material is a very important issue. It adopts tantalum-iridium series coated titanium electrode, which has low oxygen overpotential and is not corroded by electrolyte. Iridium oxide coating shows excellent electrolytic durability. The initial anode potential is 1.51V. After 6000 hours, it is 1.64V. The coating weight loss is 0mg/M2.
When lead-based alloy electrodes (containing Sb6%~15%, or Ag1%) are used in electrolysis production, the lead anode will dissolve, consuming the anode material, affecting the service life of the anode, and the lead dissolved in the solution will remain on the cathode. Precipitation increases lead impurities in the metal and reduces product quality. The nail coating will be seriously damaged under this condition and should not be used. The initial anode potential is 1.48V. After 1000 hours, it rises to 2.0V, and the anode has been passivated.
Application fields: electrolytic production of non-ferrous metals, sterilization of food utensils, electrolytic silver catalyst production, wool spinning mill dyeing and finishing wastewater treatment, electrolytic manufacturing of copper foil, steel plate galvanizing, chromium plating, electrolytic oxidation method for mercury recovery, germanium plating, palladium plating, gold plating, Water electrolysis, molten salt electrolysis, battery production, cathode protection, ionized water production, printed circuit boards,
