What is the difference between hot-dip galvanizing and electro-galvanizing in galvanized corrugated nails? What is the specific process, I will give you a detailed introduction below.
The process of galvanizing corrugated nails is generally divided into two common galvanizing methods: hot-dip galvanizing and electro-galvanizing. The difference between the two is mainly in terms of production technology, cost, and environmental requirements, and the effects and effects produced are similar and produced. Speaking of the difference between galvanizing, we must first introduce what is galvanized corrugated nails? In fact, this is to put a layer of zinc on the surface of the corrugated nails. Therefore, it has corrosion resistance in performance, and its surface is plated with zinc, which greatly increases its service life.
Contest between the production processes of galvanized corrugated nails
galvanized corrugated nails have been widely used in decorative building materials, wood processing, furniture making and other industries due to their high-quality physical properties. The galvanized corrugated nail technology improves the product performance of the corrugated nails and improves the corrosion resistance, which makes the galvanized corrugated nails very popular in the hands of manufacturers. As mentioned above, the manufacturing process of corrugated nails mainly adopts two processes: electro-galvanized and hot-dip galvanized.
1. Hot-dip galvanizing is carried out in the state that 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 to form an alloy layer. With this time, the surface layer Zinc ions slowly diffuse into the iron, and eventually all cover the paste. The zinc solution layer on the surface will become a zinc layer after cooling.
2. Electro-galvanizing uses the movement of the positive and negative ions of the electrode to galvanize. The positive and negative electrodes of the zinc solution in the liquefaction are connected to the negative electrode of the corrugated nail. The anion will move to the positive electrode under the action of the current. The corrugated nail itself is made of steel, zinc It forms a micro-battery with steel during electroplating, and the corrugated nail steel body is protected by the cathode to form a plating layer.
Performance comparison between hot-dip galvanizing and electro-galvanizing
1. The electro-galvanized layer is thicker and evenly covered, indicating that it is flat and smooth. The zinc layer is relatively pure, can adapt to various environments, and has very good corrosion resistance. The corrosion degree in a strong acid and alkali environment is not very ideal.
2. The hot-dip method is nominally an iron-zinc ion alloy layer, the zinc layer tightly covers the surface, and the surface layer of the iron-zinc mixed layer is very wear-resistant. The ductility is also good, and it can be processed by drawing and bending. General corrugated nails Made of carbon steel, the surface is galvanized, corrosion-resistant, can be used for a long time without short-term corrosion. Another main feature is its high cost performance, so it is more often used in places that are prone to humidity. And now the corrugated nails on the market are a type of nail specifically used to fix asbestos tiles, and the market supply is relatively sufficient. Therefore, galvanized corrugated nails are the best supplies for fixing plastic products and asbestos products. So on the whole, the effect and ease of use of our corrugated nails are unmatched by other nails. In the future use and selection process, we can choose the appropriate corrugated nails to use according to our own needs.
Galvanized corrugated nails have become the first choice of the majority of manufacturers due to their superior performance, and the production process is hot-dip, which is more widely used. Its production process is simpler than electroplating and has corresponding advantages in price, but the electroplated corrugated nails are smooth It is beautiful and has certain advantages in application, so the application of the two is still the same.
