In the process of using electrolytic degreasing powder for alloys, cathodic degreasing is a common and important process. The method of cathodic degreasing can effectively remove the oil on the surface of the workpiece and improve the quality of the plated layer. This article will introduce the characteristics of cathodic degreasing.
Cathodic degreasing is a process in which the workpiece is connected to the cathode one pole of the electrolyzer power supply, energized in the electrolyzer, and an electrochemical reaction is used to remove the oil. The main features of the method include:
1. Mechanism of electrolytic reaction: Hydrogen precipitation reaction occurs on the surface of the cathode workpiece, and a large number of tiny bubbles are generated during the formation of hydrogen, which can effectively strip the oil particles attached to the surface of the workpiece.
2. Suitable for detailing: Due to the small size and large number of hydrogen bubbles, it is possible to meticulously clean down to the tiny cracks and pores of the workpiece, thus ensuring that the surface of the workpiece is clean without any dead space.
3. Gentle treatment: Compared with anodic degreasing, the current density and cleaning strength during cathodic degreasing is relatively gentle, avoiding corrosion or damage to the surface of the workpiece.
Bigely Electrolytic Degreasing Powder for Alloys BC-1108, as a degreasing powder specially designed for alloy products, is suitable for cathodic degreasing process and it has the following advantages:
1. Good degreasing ability: BC-1108 can effectively remove all kinds of oil, especially suitable for alloy workpieces with fine and complex structure.
2. Mild formula: its main ingredients do not contain phosphate, alkaline and easily soluble in water, so that in the process of cathodic degreasing on the surface of the workpiece is more gentle, reducing the corrosion of the workpiece.
3. Decorative plating: workpieces used for decorative plating, such as jewelry, ornaments, etc. Cathodic degreasing can ensure cleanliness and enhance the finish and adhesion of subsequent plating.
