The Difference Between Hot-Dip Galvanizing and Electro-Galvanizing
Galvanizing is a process of zinc coating, with hot-dip galvanizing involving melting zinc and electro-galvanizing using an electrolytic method. While their manufacturing processes differ significantly, the final products may appear similar. So, how can we distinguish between hot-dip galvanizing and electro-galvanizing? Let's delve into it. Firstly, Distinction in Processes: Hot-dip galvanizing involves multiple processing steps, including oil removal, acid pickling, immersion in a flux bath, drying, and finally immersion in a molten zinc bath for a specific duration. On the other hand, electro-galvanizing, also known as zinc electroplating, utilizes an electrolytic process. After oil removal and acid pickling, the workpiece is immersed in a solution containing zinc salts. By connecting to the electrolytic equipment, zinc deposits onto the workpiece via directed movement of current between positive and negative poles. Secondly, Differentiation in Appearance: Hot-dip galvanized coa...
