Large coil galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Galvanized iron wire has good toughness and elasticity, Z high zinc content can reach 300 grams/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics.
Galvanized wire and other galvanized process compared to galvanized low carbon steel wire plating before cleaning requirements are low. However, under the trend of constantly improving the quality of galvanized layer, some pollutants brought into the plating tank are obviously harmful. Since cleaning the galvanizing layer is time-consuming and reduces production, proper cleaning and effective rinsing of the substrate prior to plating is very important.
Defects such as surface film layer and surface inclusion can be found and treated by conventional techniques. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. The presence of a large number of small homogeneous particles in the tank can stabilize the foam layer, using activated carbon mat to remove surface active substances, or through filtration to make the foam unstable, 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. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields.
