Antirust Mechanism of Zinc Phosphate Chemical Antirust Pigment
The chemical corrosion-inhibiting anti-rust pigment itself has certain chemical activity. It can passivate or form an inert protective layer on the metal surface by reacting with certain components in the metal surface or coating to achieve the purpose of anti-rust.
Anti-rust mechanism: Phosphate ions react with the metal surface to passivate the metal. Zinc ions can also form insoluble complexes, which play a role in cathodic protection, with excellent corrosion resistance and good stability. The made paint, such as epoxy zinc phosphate primer, has a good protective effect on the corrosion of steel structures.
Another type of aluminum tripolyphosphate will dissolve and ionize under the coating, and combine with metal ions at the anode to form an insoluble passivation film. The passivation film has high hardness and strong adhesion.
