If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

After a long time of use, it will not rust after the corrosion layer on the surface of the hot-dip galvanized barbed wire has problems, because the material inside the stainless steel barbed wire is the same as the material on the surface.

Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.

Weigh each reel of wire of different specifications, not less than the reel weight required in the contract, and record the value. Contact detection. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.

The amount of zinc on the surface of high zinc barbed rope is about 5 times that of general zinc barbed rope, thus greatly prolonging the time of rust resistance. In the appearance of the two products are silver white and metal texture is better, for the distinction between the two products is more difficult to distinguish if it is a layman, but for long-term work of professionals can be separated from the two at a glance.

First, galvanizing can enhance the corrosion resistance of the product. Zinc has high potential and excellent anodic protection. When the surface of the product is galvanized, zinc will have an electrochemical reaction with oxygen and water in the environment, thereby forming a dense zinc oxide protective film, preventing the metal from further contact with external oxygen, water and other substances, slowing the corrosion rate of the metal. Galvanized products after wire drawing processing, because the surface of the product has a more dense zinc oxide protective film, it can better resist external corrosion and improve the corrosion resistance of the product.
