2. Ruthenium-iridium titanium positive plate
The size of anode is stable and the distance between electrodes does not change during electrolysis, which can ensure the electrolysis operation under the condition of stable tank voltage.The working power is low, the electric energy consumption is small, can reduce the consumption about 20%.Titanium anode has a long working life. The metal anode can resist the corrosion of chlorine and alkali in the chlorine industry.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.The current density can be increased.
For example, in the production of chlorine-alkali by diaphragm method, the current density of graphite electrode is 8A/M2., titanium anode can be multiplied up to 17A/M2;In this way, the output can be doubled in the same electrolytic plant and electrolytic cell.Strong corrosion resistance, can be used in many corrosive, special requirements of the electrolytic medium.It can avoid the short circuit of lead anode after deformation and improve the current efficiency.The matrix titanium can be used repeatedly.

3. Tantalum-iridium titanium positive plate
It is a very important problem to choose the proper anode material for extracting metal by electrolysis in sulfuric acid solution and separating oxygen on the anode.Titanium electrode coated with tantalum-iridium system has low oxygen overpotential and is not corroded by electrolyte.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.
When lead alloy electrode (containing sb6% ~ 15% or ag1%) is used in electrolytic production, the lead anode will dissolve, consuming the anode material and affecting the service life of the anode. Moreover, the lead dissolved in solution will be precipitated on the cathode, increasing the lead impurity in the metal and reducing the product quality.
Ruthenium coating will be seriously damaged in this condition, so it is not suitable to be used.The initial anode potential was 1.48v. After 1000 hours, the anode was increased to 2.0v.
