In the production process of alkaline galvanizing, sometimes there will be pitted bubbles in the galvanized layer of the workpiece, which will seriously affect the appearance of the workpiece and the performance of the coating, and the customer will not accept it.So does this phenomenon mean that the alkaline galvanizing brightener is used too much?
In the production process of alkaline galvanizing, sometimes the coating brightness of the workpiece is not enough, and the operator will add more alkaline galvanizing brightener to improve the brightness of the galvanizing layer.And sometimes the coating is not bright, even if the alkaline galvanized brightener is added, the brightness of the coating is not improved, why is this?
In the production process of using medium phosphorus electroless nickel plating solution, some customers reported that it is easy to deposit a layer of electroless nickel on the tank wall and tank bottom of the electroless nickel plating tank, which affects the product quality and shortens the service life of the plating solution.So, how should we avoid the deposition of chemical nickel on the tank wall and tank bottom during the production process?
In the production process of using alkaline galvanizing brightener, sometimes the galvanized layer of the workpiece will appear pitted small bubbles, which will seriously affect the appearance of the workpiece and the performance of the coating, and the customer will not accept it.o does this phenomenon mean that the alkaline galvanizing brightener is used too much?
In the production process of using sulfate tin plating additives, the concentration of Sn2+ in the plating solution is often out of control.With the prolongation of production time, the concentration of Sn2+ will rise rapidly. When the concentration of Sn2+ exceeds 35g/L, the plating solution begins to deteriorate and the deep plating ability is poor.What is the main reason for the out-of-control Sn2+ concentration?
In the production process of using acid matte tin additives, sometimes the coverage of the tin plating layer is poor, which affects the quality of the plating layer. What is the reason?
