  • 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.

  • “Wet” hot dip galvanizing is also called “molten solvent method” hot dip galvanizing. Iron and steel workpiece through degreasing, pickling and cleaning, it is necessary to set in a special box above the surface of the molten zinc in the “molten solvent” (also called cosolvent), and then into the zinc liquid to galvanized. The molten solvent is usually a mixture of ammonium chloride and zinc chloride, but also other chlorine salts.
