Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.

Another way is to have special equipment for measuring, which is expensive and impossible for ordinary users to buy.

Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
