Problems solved by technology

Due to the corrosion resistance of pure titanium in the electrolysis of manganese dioxide, titanium anodes made of pure titanium have been widely used in the production of electrolytic manganese dioxide, but pure titanium anodes are prone to passivation, and passivation The film continues to thicken, the conductivity drops rapidly, and the electrolysis process cannot continue

In order to overcome the defect that pure titanium anodes are prone to passivation, some people propose to spray precious metals on the surface of pure titanium metal to improve its anti-passivation effect, but the coating is easy to fall off, the service life is short, the processing cost is high, and the practical value is not high.

Although the anode made of titanium-manganese alloy improves the anti-passivation effect and reduces power consumption, due to the poor plasticity of the material, it cannot be processed into plates, and because the electrolytic manganese dioxide production process requires a certain intensity of knocking, even if it is processed into The bar is also extremely brittle, so it is difficult to get a large number of applications in the production of electrolytic manganese dioxide
