There are two types of galvanized corrugated nails, which are hot-dip galvanized and electro-galvanized. They have their own characteristics and disadvantages.
Performance comparison of hot-dip galvanizing and electro-galvanizing
1. The galvanized layer is relatively thick and covers evenly, indicating that it is smooth and smooth. The zinc layer is relatively pure, able to adapt to various environments, and has very good corrosion resistance. The degree of corrosion in a strong acid and alkali environment is not ideal.
2. The hot-dip method is nominally an iron-zinc ion alloy layer, the zinc layer tightly covers the surface, and the surface iron-zinc mixed layer is very wear-resistant. The ductility is also good, and it can be processed by drawing or bending.
3. Hot-dip galvanizing is carried out in the state where zinc is also liquefied, that is, the corrugated nails are placed in a liquefied zinc solution layer. At high temperatures, iron and zinc on the surface of the corrugated nails dissolve each other to form an alloy layer. With this time, the surface layer The zinc ions slowly diffuse into the iron, eventually covering all the paste, and the zinc solution layer on the surface will become a zinc layer after cooling.
4. Galvanizing is to galvanize by moving the positive and negative ions of the electrode, butt the positive and negative electrode of the zinc solution in the liquefaction with the negative electrode of the corrugated nail. 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.
