Precautions for galvanized iron wire in galvanizing process
The galvanized iron wire manufacturer is made of high-quality low-carbon steel wire rod. It is made of high-quality low-carbon steel, which is processed by drawing, pickling, rusting, high temperature annealing, hot-dip galvanizing and cooling. Galvanized wire is further divided into hot-dip galvanized wire and cold-galvanized wire (galvanized wire).
The duration of the galvanizing protection is highly dependent on the thickness of the coating. Generally speaking, in the relatively dry main gas and indoor use, the thickness of the galvanized layer only needs 6-12 μm", and in the harsh environment, the thickness of the galvanized layer needs 20 μm. 50μm". Therefore, the influence of the environment should be considered when selecting the thickness of the galvanized layer. After the passivation treatment of the galvanized layer, a bright and beautiful color passivation film can be formed, which can significantly improve the performance of the paddle decoration performance.
The galvanized wire should be galvanized evenly, the first is its cross section, and the second is the longitudinal uniformity. In the actual operation process, such as the vibration of the steel wire, the surface scum in the plating pot, etc., the galvanized layer on the surface of the galvanized wire is accumulated, and efforts should be made to solve the problem.
