Treatment of antirust aluminium plate before electroplating

The first is the design method of selection and improvement of pretreatment process. The aluminum plating pretreatment including degreasing, acid etching, chemical plating, plating or replacement of pre plating four. One of the more important process is the key to the electroless plating or replacement plating, therefore, often do experiments are concentrated in this working procedure. 

Of course, different products and different processing methods have different requirements on the pretreatment, such as casting and rolling of aluminum parts before treatment is very different, and even the same kind of processing methods, different aluminum also has various pretreatment processes such as aluminum, copper containing the amount of it directly affect the binding force of the coating. Harbin Dong Xing Aluminum Co., Ltd is a competent and reliable Aluminum sheet wholesales.

Test solution antirust aluminum electroplating, and contrast test system, the need for different treatment of selected sample pretreatment, and then electroplating processing the same, then detect its binding force. The point of comparison test is to ensure that in addition to difference points in process, other processes are the same the conditions, otherwise there is no comparability and cannot be assessed.
