What matters need to be paid attention to before galvanizing galvanized wire?

Galvanized wire has a very important role in our life, so do you know what matters need to pay attention to before galvanized wire?

Galvanized wire is made of high quality low carbon steel rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanizing. Cooling and other processes from the process. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Galvanized iron wire has good toughness and elasticity, the limit of zinc can reach 300 grams/square meters. It has the characteristics of thick galvanized layer and strong corrosion resistance.

What should be paid attention to before galvanizing galvanized wire?

Galvanized wire and other galvanized process compared to galvanized low carbon steel wire before plating cleaning standards are low. However, under the current trend of increasing the quality level of the galvanized layer, some pollutants are brought into the plating tank. Clearly something harmful. Because cleaning the galvanizing layer wastes a lot of time and reduces production, it is important to have proper cleaning and effective rinsing of the substrate prior to plating.

Before galvanizing, defects such as surface film layer and surface inclusion can be found and treated by conventional technology. Excess foaming is caused by the introduction of surfactants such as soap and saponifiable fats into the bath. A moderate rate of bubble formation may be harmless. The existence of a large number of small homogeneous particles in the bath can stabilize the foam layer, and activated carbon matting is used to remove surface active substances. Or by filtering the foam to make it less stable, both are effective measures; Other measures should also be taken to minimize the introduction of surfactant. The introduction of organic matter can reduce the electroplating speed obviously. Although the chemical formulation is conducive to high deposition rate, the coating thickness can not meet the requirements of organic matter, so activated carbon can be used to treat the bath.
