What is the difference between hot dip galvanizing and cold galvanizing? Hot-dip galvanizing and cold-galvanizing are both special galvanizing methods, but they are very different in production, use function and product performance. Today we will distinguish between these two items in detail. What is hot dip galvanizing? Hot-dip galvanizing, also known as hot-dip galvanizing, is to remove the oil and rust of the steel workpiece to present a clean and wet surface, and immediately immerse it into a plating tank where zinc has been heated and melted in advance. A method of forming a zinc coating. What is cold galvanizing? Cold galvanizing is to hang the workpieces that have also been degreasing and rust-free, showing no pollution and infiltration, on the cathode in a special electroplating tank, and zinc is used for the anode. Connect the DC power supply, the zinc ions on the anode migrate to the cathode, and discharge on the cathode, so that the workpiece is coated with a zinc layer. What is galvanized pipe? It is also called galvanized steel pipe. This kind of pipe is added with a layer of galvanized layer on the surface of steel, so the material inside the galvanized pipe is made of steel. Zinc can effectively prevent corrosion and rust of steel, and at the same time, it can help the service life of steel to be extended. Classification of galvanized pipes Galvanized steel pipes are divided into hot-dip and cold-dip: hot-dip is to melt zinc, and then pass other metals (such as iron) through the zinc solution to form a galvanized layer on the surface; cold-dip (electroplating) is to put metal The electroplating layer is formed by depositing zinc on the surface by immersing it in an electrolyte solution containing zinc and energizing it for electroplating. From the outside, the electroplating is relatively smooth, and the amount of zinc plating is less. . The difference between cold galvanizing and hot-dip galvanizing is different in corrosion resistance. Hot-dip galvanizing is dozens of times that of cold galvanizing. The way of operation is different: hot-dip galvanizing is zinc plated in molten zinc solution of 450-480 degrees. Plating is the thickness of zinc galvanized layer plated by electroplating or other methods at room temperature, and the thickness of hot-dip galvanizing is much larger than that of cold galvanizing. The surface smoothness is different. The appearance of cold galvanizing is smoother and better than that of hot galvanizing. Cold galvanizing can only be plated on one side. Hot galvanizing requires full plating adhesion. Therefore, it is better to hot-dip galvanize.
