TRANSCRIPT
Zinc anode is primarily used for corrosion prevention in seawater of steel and aluminium equipment and structures such as ship hull, ballast tank, heat exchanger, condenser, pier, pilling, etc. It can also used as packaged anodes as grounding cells on electrical motors panels, conduits, and across insulators on pipelines to limit dangerously high voltages.
Zinc anode provides the lowest driving voltage in comparison with aluminium anode and magnesium anode. Therefore, it does not easily cause overprotection which leads to coating disbondment and hydrogen damage of high strength steel.
purity zinc ingot 99.995% and other high quality raw materials with rigid production and inspection procedure to ensure our zinc anode meet or above the international standard requirement.
