Testing the effect of electrochemical degreasing is a . This test is usually a serial comparison method. And it is necessary to make a plated sheet to quantitatively evaluate the binding force to indirectly evaluate the effect of degreasing. At the same time, a parallel comparison should be made with ordinary chemical degreasing or a known electrochemical degreasing agent.
The test piece in the same oily state is degreased in different degreasing processes, of course, including tested electrochemical degreasing process, and multiple process schemes can be prepared at the same time, such as cathodic degreasing, anode degreasing, yin and yang Extremely combined degreasing, etc. Then, the degreasing completed test pieces were electroplated under the same process conditions, and then the coating binding force was tested to evaluate the effect of different electrochemical degreasing schemes.
If you only need to make a simple comparison, you can chemically degrease , and observe the surface hydrophilicity with the empirical method introduced above. You will find local oil blooms, and then perform electrochemical degreasing. It can be found that the surface is completely hydrophilic.
