Problems solved by technology

This type of electrode has good electrocatalytic performance for the precipitation of chlorine, good durability, and the ability to inhibit oxygen precipitation. The disadvantages are that the corrosion resistance in the chlor-alkali environment is not ideal, the strength is low, the resistance is high, and the power consumption is large. It is easy to cause unstable production during consumption; (2) In the stage of platinum group metals and lead alloy electrodes, although the performance of such electrodes has been greatly improved compared with graphite, there are also problems such as expensive platinum electrodes, heavy weight of lead electrodes, and oxygen Large precipitation overpotential, low electrochemical catalytic performance, easy deformation and poor conductivity, high energy consumption and other disadvantages, especially in non-sulfuric acid systems, the dissolution of lead cannot be used, and further improvement is needed; (3) Titanium-based coating anode, titanium has Stable oxide layer protection, so that the anode current cannot pass through
