Let me provide more details on the surface treatment processes for galvanized sheets:
Cleaning: This process involves removing any dirt, oil, or other contaminants from the surface of the galvanized sheet. It is usually done using alkaline or acidic cleaners, followed by rinsing with water.
Degreasing: In this step, any grease or oil residues are removed from the surface. Solvent-based degreasers or alkaline cleaners are commonly used for this purpose.
Passivation: Galvanized sheets are prone to corrosion over time, especially when exposed to certain environments. Passivation is a process that helps protect the surface by forming a thin, protective layer. It is typically done by applying a chemical solution, such as chromate or phosphate, to the galvanized sheet.
These surface treatment processes help ensure the cleanliness and durability of galvanized sheets, making them suitable for various applications in industries such as construction, automotive, and manufacturing.
