how to do drywall screwsTherefore, when the zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms are diffused with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with the iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with the zinc and sinks into the bottom of the hot galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

This plating method not only has the corrosion resistance characteristics of galvanized wire, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosion environment.

The size of the galvanized layer of galvanized iron wire is related to the anti-corrosion ability and application effect of galvanized wire. The thickness of the galvanized layer of the general standard galvanized wire products should be tested after the product is formed. There are three specific test methods. Weighing method and cross section microscopy method are destructive experimental methods, and magnetic method is a relatively rigorous non-destructive method, but the measurement steps and requirements are relatively high, so they are rarely used in specific applications. The first two methods are intuitive and common methods.
