In China, the cathodic electrophoretic coating technology is widely used. In order to meet the requirements of continuous and ultra-thick electrophoretic paint, the traditional stainless steel anodes rely on passivation state to work. Spark dissolution and the formation of passivation film are greatly affected by pulse current, and it is also difficult to control in actual production. Moreover, due to the influence of Cl - in the paint solution, the lifespan of stainless steel anodes is relatively short, sometimes only reaching 1-3 months. These issues are increasingly affecting normal production and management, directly affecting the economic benefits of enterprises.
In order to improve this traditional process and improve production efficiency and efficiency, the insoluble anode of the titanium based mixed oxide coating produced by Baoji Changsheng Titanium company only needs to consume a small amount of active coating during the working process. It has good electrocatalytic activity, strong corrosion resistance, long service life, and can also prevent traditional anode metal ions from precipitating and polluting the paint solution. During the electrophoretic coating process, when the paint film deposited at a certain location of the workpiece is thick, The conductivity here decreases, and the rate of deposition of new paint film significantly decreases. However, areas with thin or no paint film can continue to deposit, resulting in a uniform and uniform thickness of the entire electrophoretic coating, with a beautiful appearance. This type of anode can be suitable for use in large equipment.
Base material: GR1/GR2
Shape and size: Flexible design, mostly plate or tube type, can also be customized according to the actual working conditions of customers.
Low oxygen evolution potential reduces power consumption to a certain extent.
Long service life, avoiding the impact of anode frequent replacement on production efficiency and process.
High stability, just operate according to requirements, easy management and maintenance.
Technical services are guaranteed, providing anode repair and recoating services. After the coating loses its activity, the substrate can be repaired and recoated, saving costs for customers.
In 2019, the German BMW production line ordered titanium anode plate for the field of electrophoretic coating.
