The galvanized sheet manufacturer points out that before electroplating, oil removal, also known as degreasing, must be carried out on the surface of the parts. The effect of oil removal directly affects the electroplating quality. The oil on the surface of the workpiece is mainly various hydrocarbons, some of which do not react with alkali and cannot be saponified, so it is called unsaponifiable oil, and the removal of such oil can only be realized by emulsification or dissolution; while other oils have saponification with alkali, called saponification oil, which can be removed by saponification, emulsification and dissolution. The commonly used oil removal methods include physical mechanical method, organic solvent method, chemical method, electrochemical method and the combination of the above methods.Electrochemical degreasing is a process of removing oil stains on the surface of parts in alkaline solution with parts as anode or cathode, stainless steel plate, nickel plate, nickel plated steel plate or titanium plate as the second electrode under the action of direct current. The electrochemical oil removal fluid is similar to the alkaline chemical oil removal fluid, but the color aluminum plate manufacturer points out that it mainly relies on the electrolysis to strengthen the oil removal effect. Generally, the electrochemical oil removal is more effective, faster and more thorough than the chemical oil removal.
