What is the principle of hot galvanizing to keep the lamp pole from being corrupted? Anyone who has studied chemistry should know the principle of "sacrificial anode". Zinc is a metal element more active than iron. When the combination of zinc and iron (zinc-iron compound) is corroded to form an electrode, electrons will transfer to iron, thus maintaining iron and sacrificing zinc. At the same time, zinc can easily form a dense oxide layer in the atmosphere, which protects zinc from deeper oxidation. Now there are three anti-corrosion methods for solar street lamp poles: 1. Hot galvanizing and anti-corrosion. At the beginning, solar street lamp manufacturers chose a good galvanizing method. 2, cold galvanizing, anti-corrosion can follow hot galvanizing
