decorative barbed wire

The barbed wire factory will store the inventory of the barbed wire blade in the appropriate place because of the understanding of the product characteristics.

The wire after the first plating, its strength limit is also higher than the first plating, plated zinc and then made of wire not only toughness and high strength. There is a lower figure in the strength limit of galvanized iron wire because of the quality of zinc, because the strength of zinc technology is several times smaller than the wire itself. It is difficult to hot-dip galvanize drawn wires, and it is impossible for finer and very fine wires to be coated with the desired thickness of smooth zinc.

If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
