  • Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.

  • The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc solution, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the gravitational attraction between the atoms is relatively small.
