Corrugated nails are widely used in construction and building materials, furniture making, wood processing and other fields. Galvanized corrugated nails are highly valued as a hardware product. Not only is it widely used, but it also has higher performance than corrugated nails, and its ability to resist corrosion is greatly improved. Therefore, the shelf life of galvanized corrugated nails is very long, which is also popular for galvanized corrugated nails. One of the reasons. Corrugated nails are mainly produced by electro-galvanizing and hot-dip galvanizing. Let ’s take a look together.
1. Hot-dip galvanizing is carried out in the state where the zinc is also liquefied. The corrugated nails are placed in the liquefied zinc solution layer. At high temperatures, the iron and zinc on the surface of the corrugated nails dissolve each other to form an alloy layer. With this time, the surface layer ’s Zinc ions slowly diffuse into the iron, eventually covering the whole surface, and the zinc solution layer on the surface will become a zinc layer after cooling.
2. Electroplating is the galvanization using positive and negative ion movement of the electrode. The positive and negative electrodes of the zinc solution in the liquefaction are connected to the negative electrode of the corrugated nail, and the anion will move to the positive electrode under the action of current. The corrugated nail itself is a steel body. Zinc and steel form a microbattery during electroplating. The corrugated nail steel body is protected by the cathode to form a plating layer.
