The large roll of galvanized wire is just like the literal meaning, which is coated with a layer of zinc on the surface of the low carbon steel wire material, beautifying the appearance at the same time, and improving the corrosion resistance of galvanized wire. Zinc is soluble in acids and alkali, so it is called a double soluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.
In the atmosphere containing sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the atmosphere containing organic acids at high temperature and high humidity, galvanized wire galvanized layer is easy to be corroded. The uniformity of the galvanized layer on the surface of the galvanized wire and the color of the galvanized wire, the galvanized layer on the surface of the galvanized wire with good quality is uniform, the zinc adhesion is good, and the color is white and bright, there is no leakage plating and rust points.
If the galvanized wire surface is black and the galvanized layer is thin and uneven, this galvanized wire is partly because the inventory storage time is longer, and it may also be because the production technical requirements of galvanized wire do not meet the standard standards and lead to galvanized wire quality problems. According to the different uses of galvanized wire, galvanized wire has soft and hard points, then the galvanized wire for binding requires the flexibility of galvanized wire is better, and the flexibility of galvanized wire is good, which can facilitate the worker to operate well.
For the welding of galvanized wire generally requires a certain hardness, after the acceptance of galvanized wire, feel is the first thing to do, and the other is to test on the machine, because the average user is not testing equipment, the machine trial is also a very inconvenient test method. Use a micrometer to measure the diameter of the electric galvanized wire uniformly, and keep it about 0.02mm above and below the contract signing standard, and the appearance is neat, no leakage plating, no mess.
