Electrogalvanizing refers to coating Zn or Sn on both sides of steel strip, and it is commonly applied to process automobile and home appliance. Our galvanized steel sheet anode is especially designed for this process.
The electrogalvanizing line comprises of some electrolytic tanks. Inside each of the tank, there are several titanium anodes with IrO2 coating. The steel strip travels through these tanks with a high speed, and the distance between anode and cathode is about 2cm.
This process involves zinc deposition at a high current density (6-10kA/m2) from the made-up electrolyte compositions (30% H2SO4, 1mol/L ZnSO4, PH=1.5), and the temperature is 55℃. In addition, a titanium anode with IrO2-Ta2O5 coating has a very long life span which is over 40,000kAh.
