As an electrode material, platinum is characterized by high corrosion resistance, high electrocatalytic activity, high oxygen precipitation potential and low hydrogen precipitation potential. However, the scarcity and high price of platinum resources restrict the application of pure platinum electrodes in electrochemical industry. The platinum-titanium anode is a special electrode made of titanium with high specific strength, good thermal stability, high corrosion resistance and excellent self-passivation ability as the substrate and platinum plating (coating) layer prepared by a special process,so that the obtained platinum-titanium anode has the performance of pure platinum electrode and can significantly reduce the cost, so it is widely used in the field of electrochemistry. PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
Technology of platinum and titanium anodes
At present, the commonly used preparation methods of platinum and titanium anodes are: physical vapor deposition method, electroplating method, and sintering method.
Advantages of sintered platinum coated titanium mesh.
The service life of platinum and titanium anodes depends on the bonding force between the platinum coating and the titanium substrate in the case of the same platinum coating thickness,and the general failure of platinum and titanium anodes is not due to the consumption of the platinum coating, but to the poor bonding force between the platinum coating and the substrate, which causes the platinum coating to fall off. belongs to the cold coating process, the characteristics of the plating process determines that the internal stress of the coating is high, brittle, poor uniformity, high porosity, easy to burst, once the substrate has deformation, the coating will fall off. Therefore, compared with platinum and titanium anodes, sintered platinum coated anodes have greater performance advantages.
Applications of platinum coated titanium mesh
Platinum plated titanium anode platinum titanium mesh platinum electrode application areas. Electrolysis of metals, galvanization of steel plates, electrolytic production of ionized water, electrolytic chemical preparation of perchlorate and hypochlorite, electroplating industry, cathodic protection, seawater desalination, organic electrolytic synthesis, descaling and sterilization, and other fields.
