The process of galvanizing corrugated nails is generally divided into two commonly used galvanizing methods: hot galvanizing and electrogalvanizing. The difference between the two is mainly in terms of production technology, cost, and environmental requirements, and the effects and effects are similar. Speaking of the difference between galvanized, first of all, what is galvanized corrugated nail? In fact, in popular terms, it is a layer of zinc "coated" on the surface of corrugated nails. Therefore, it has corrosion resistance in performance. Because its surface is galvanized, it greatly increases its service life.
Galvanized corrugated nails have been widely used in decorative building materials, wood processing, furniture manufacturing and other industries due to their high-quality physical properties. The galvanized corrugated nail technology improves the product performance of corrugated nails and improves the corrosion resistance, which makes galvanized corrugated nails very popular in the hands of manufacturers. As mentioned above, corrugated nails are mainly produced by electro-galvanizing and hot-dip galvanizing.
1. Hot-dip galvanizing is carried out in the state where zinc is also liquefied. Corrugated nails are placed in a liquefied zinc solution layer. At high temperatures, iron and zinc on the surface of corrugated nails dissolve each other to form an alloy layer. Zinc ions slowly diffuse into the iron, eventually covering the surface, and the zinc solution layer on the surface will become a zinc layer after cooling.
2. Galvanizing is to galvanize using positive and negative ion movement of the electrode, butt the positive and negative electrodes of the zinc solution in the liquefaction with the negative electrode of the corrugated nail, and the anion will move to the positive electrode under the action of the current. The corrugated nail itself is a steel body, zinc Microcells are formed with steel during electroplating, and the corrugated nail steel body is protected by the cathode to form a plating layer.
Comparison of hot-dip galvanizing and electro-galvanizing
1. The electroplated zinc layer is relatively thick and covers evenly, indicating that it is smooth and smooth. The zinc layer is relatively pure, can 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. General corrugated nails Made of carbon steel, the surface is galvanized, corrosion resistant, and can be used for a long time without short-term corrosion. One of the most important features is its high cost performance, so it is more used especially in some wet places. Corrugated nails currently on the market are a type of nails specifically used to fix asbestos tiles, and the market supply is relatively sufficient. Therefore, galvanized corrugated nails are the best supplies for fixing plastic and asbestos products. Therefore, in general, the effect and convenience of our corrugated nails are unmatched by other nails. In the future use and selection process, we can choose our own corrugated nails for use.
