Large galvanized wire as literally, is coated with a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc is soluble in acids as well as bases, so it is called a doubly soluble metal. Zinc hardly changes in dry air. In humid air, a dense alkaline zinc carbonate film is formed on the surface of zinc. In the atmosphere of sulfur dioxide, hydrogen sulfide and Marine, zinc corrosion resistance is poor, especially in the atmosphere of high temperature and high humidity containing organic acids, galvanized wire galvanized layer is very easy to be corroded.
The surface of galvanized wire galvanized layer of uniformity and galvanized wire color, good quality galvanized wire surface galvanized layer is uniform, zinc adhesion is good, and the color and luster is white, there is no leakage of plating and rust and other problems. If the large volume of galvanized wire surface hair black, galvanized layer is thin and uneven, this kind of galvanized wire is partly because of the storage time is longer, it may also be because of the production technical requirements of galvanized wire, galvanized wire quality problems caused by the standard standard.
According to the use of galvanized wire, galvanized wire has soft and hard points, then used for binding galvanized wire requires galvanized wire flexibility is better, galvanized wire flexibility can be easy for workers to operate good operation; And for welding galvanized wire generally requires a certain hardness, in the acceptance of large galvanized wire, feel is the first thing to do, in addition to the machine test, because the general user is not testing equipment, the machine is very inconvenient to try.
