| Yuanjiang Brand - Zinc Oxide for Phosphating Solution typically uses ZnO 99.7% produced by the indirect method. Zinc oxide primarily provides zinc ions in the phosphating solution and is the main component for forming the phosphating film. Zinc oxide reacts to produce zinc phosphate, which can be used for anti-corrosion and rust prevention on metal surfaces, forming a zinc coating on the metal surface as an anti-rust pigment. |
| Overall reaction equation of the phosphating solution: |
Phosphoric acid + Zinc oxide → Zinc dihydrogen phosphate + Water |
The concentration of zinc dihydrogen phosphate in production and manufacturing must be effectively controlled to achieve the goal. |
