The alkaline zinc plating is suitable for hanging plating and rolling plating production. The coating is soft, bright and easy to passivate with chromate.
The principles of alkaline zinc plating mainly include the following points:
1. Use of alkaline solution: Alkaline zinc plating uses an alkaline solution with zinc oxide as the main zinc source, and usually sodium hydroxide, zinc plating additives and certain stabilizers are added to form a stable plating environment. The pH value of the alkaline plating solution is relatively high, usually above 12.
2. Plating characteristics: Due to the small and dense zinc particles in the plating solution, this process can produce a fine, evenly distributed plating layer with good adhesion and high corrosion resistance.
3. Production efficiency: The process of alkaline zinc plating is relatively slow and the current density is low, so it is suitable for workpieces that require thicker coatings.
4. Environmental impact: The zinc plating additives used in alkaline zinc plating are more environmentally friendly and do not contain heavy metals, so they have less burden on the environment.
In summary, the alkaline zinc plating process has its unique characteristics and advantages in terms of plating solution properties, coating characteristics, production efficiency and environmental impact, and is suitable for workpieces that require a fine, uniform and corrosion-resistant coating.
