In steel galvanizing industrial production line, anode plate is the main working part, which has high cost and poor service conditions. The development of insoluble anode plays a decisive role in high-speed electroplating technology. The main characteristics of titanium anode are as follows: 1. The anode polarization potential is small, and the bath voltage of the plating bath is low, which can realize efficient and low energy consumption electroplating operation; 2. The electrode loss rate is extremely small, the anode size is stable, and the service life is long. It not only reduces the cost and workload of repairing and replacing the anode, but also improves the operation efficiency. Moreover, the spacing between the anode and the cathode strip in the plating bath can be reduced, thereby reducing the electrical energy consumed in the plating solution resistance and reducing the energy of electroplating production. 3. The electrode has good corrosion resistance, and the anode material dissolves very little into the plating solution. 4. The titanium anode adopts new materials and structures, which greatly reduces the weight of the anode and greatly accelerates the replacement and maintenance work.
