When the iron wire factory uses galvanized iron wire to bind the strengthened goods, the corresponding binding method should be selected according to the fastening node status of the strengthened goods, such as opening binding, opening binding, inserting binding and so on. The insulation layer of semi-rigid and soft insulation products should be based on the diameter of steel pipe and the size of equipment and steel pipe. The width of galvanized iron wire or glue is bound together, the width is 60mm, and the binding interval of semi-rigid insulation products shall not exceed 300mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
The insulation layer of galvanized iron wire and hard thermal insulation products can be tied with double galvanized iron wire. The binding interval is not more than 400mm, and the pipes or corresponding equipment with a nominal diameter equal to or greater than 600mm should be stopped after binding, and the galvanized steel wire surrounded must be winched. Tighten iron or wood rods, but the tightening level should be moderate, not too tight or too loose, nor damage the steel wire. Galvanized wire is made of low carbon steel wire, is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing.
Galvanized wire and other galvanized process compared to galvanized low carbon steel wire plating before the end of the cleaning standard is low. But in the current from time to time to improve the quality of galvanized layer under the trend, with small plating tank some pollutants. Obviously become something harmful. Because cleaning the galvanized layer consumes a lot of time and reduces production. Therefore, proper cleaning and effective rinsing of the substrate before plating are very important. Defects such as surface film layer and surface inclusion can be found and disposed of by conventional technology.
Excess foam is formed by the introduction of soap and surfactants such as saponified fats into the tank. Moderate foam formation rates may be harmless. The presence of a large number of small homogeneous particles in the tank can stabilize the foam layer and be matted with activated carbon to remove surface active substances. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to minimize the introduction of surfactant. The electroplating speed can be obviously reduced by the addition of organic matter.
