The hot galvanizing technology becomes the most basic and most economical and effective method for the corrosion prevention of steel materials. The hot galvanizing is to dip the steel member after rust removal into molten zinc liquid at about 500 ℃ to make the surface of the steel member adhere with a zinc layer, thereby achieving the purpose of corrosion resistance. The corrosion prevention mechanism is that the standard electrode potential of zinc is negative to iron, so that a zinc coating has the function of protecting a steel base by a sacrificial anode in water and moist air, and the service life of steel can be greatly prolonged.
The plating assistant procedure is a necessary and important link in the hot-dip plating metal process. Plating assistant is a process of immersing the degreased workpiece into a plating assistant agent solution, taking out the workpiece and forming a continuous plating assistant salt film on the surface of the workpiece, and drying is to remove the moisture on the surface of the workpiece and keep the salt film. The quality of the plating assistant effect directly influences the plating quality indexes such as plating uniformity, continuity, adhesion strength, brightness, smoothness and the like, and also influences the time and effect of the subsequent drying process, thereby influencing the production efficiency, plating metal consumption and operation environment. The plating assistant process and the plating assistant agent have a direct relation to the improvement of the plating assistant effect.
The plating assistant solution needs to be added with additives to enhance the plating assistant effect. The additive can greatly improve the adhesion uniformity of the plating solution and greatly reduce the plating leakage; the interface wettability between the liquid coating metal and the workpiece is better; the adhesion uniformity and continuity of the plating assistant agent are improved, the plating missing is prevented, the adhesion amount of the plating assistant agent can be reduced, and the consumption of the plating assistant agent is reduced; after the workpiece is immersed in the plating assistant liquid, a special hydrophobic film is formed on the surface of the workpiece, so that the drying time of the plating assistant is greatly shortened, and the production efficiency is improved; the zinc liquid splashing strength is weakened, the accident risk such as scalding is reduced, and the working environment of workers is improved; however, in the existing hot-dip metal plating process, liquid metal is splashed; the dip plating time is prolonged, and the effect of the hot dip plating is influenced due to uneven coverage.
