Introduction and Importance of Electroplating Degreasing

Electroplating degreasing is an important treatment method before electroplating to remove oil and dirt from the surface of the workpiece to ensure that the plating layer can be firmly adhered to the workpiece. The presence of oil will reduce the adhesion of the coating film and affect the quality and performance of the plating layer.

Introduction and Importance of Electroplating Degreasing
 

Electroplating degreasing is an important treatment method before electroplating to remove oil and dirt from the surface of the workpiece to ensure that the plating layer can be firmly adhered to the workpiece. The presence of oil will reduce the adhesion of the coating film and affect the quality and performance of the plating layer.

Therefore, electroplating degreasing is one of the key processes of surface treatment.
 

Plating degreasing methods alkaline degreasing: the use of alkaline solution to remove oil on the surface of the workpiece, applicable to a variety of metal and non-metallic materials.
 

Organic solvent degreasing: using organic solvents such as gasoline, alcohol, etc., through the dissolving effect to remove oil. 
 

Electrochemical degreasing: also known as electrolytic degreasing, through electrolysis to strengthen the effect of degreasing, usually more effective than chemical degreasing, faster, more thorough degreasing.
 

The principle and characteristics of electrolytic oil removal electrolytic oil removal is in an alkaline solution, parts as the anode or cathode, using stainless steel plate, nickel plate, etc. as the second electrode, under the action of direct current will be removed from the surface of the parts of oil contamination.
 

Electrochemical degreasing solution is similar to alkaline chemical degreasing solution, but it mainly relies on electrolysis to strengthen the effect of degreasing. Electrochemical degreasing is usually more effective, faster and more thorough than chemical degreasing.
