  • Zinc is a silver-white metal, brittle at room temperature, soluble in acid can also be soluble in alkali, known as amphoteric metal. Pure zinc in dry air is more stable, in humid air or containing carbon dioxide and oxygen water is small, the surface will generate a layer of basic zinc carbonate based thin film layer, it can delay the corrosion rate of zinc layer. The corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride is stronger.

  • Paint on the galvanized layer, the bonding force between each other has a great relationship with the baking temperature of the paint, and alkyd paint is coated after galvanized, and the adhesion is not a problem. After galvanized to do amino paint, paint adhesion is not very good. Do two bottom two surface, adhesion is good, if the two bottom two surface changed to two bottom three surface, that is, more paint, more baked once, again test adhesion is very bad, bad enough to tear the paint from the galvanized layer.

  • In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.
