ZINDN Dual Protection Mechanism
ZINDN is one of the few existing anti-corrosion technologies that can achieve a combination of cathodic protection and barrier protection.
Cathodic Protection
The sacrificial anode is one of the important means of cathodic protection. The sacrificial anode method is used to achieve cathodic protection of steel. Zinc is a commonly used anode material in the sacrificial anode method. The standard electrode potential of zinc is -0.76V, which is more active than iron's -0.44V. When zinc is coated on steel substrate, zinc will be preferentially corroded and released electrons to flow to the steel, thereby protecting the steel substrate from corrosion. ZINDN uses ultra-pure ultra-fine zinc dust with special conductive fusion agent, which has more excellent cathodic protection performance.
Barrier Protection
The zinc layer exposed to the environment will gradually react with water and air in the environment over time to form stable basic zinc carbonate (commonly known as white rust). The corrosion product is filled between the zinc powder gaps, making ZINDN layer denser, and further blocks and shields the corrosion of corrosive media. ZINDN layer has a self-sealing function.
