Everyone's Electroplating equipment Why should the oil be removed in the design scheme?
Degreasing is also called deoiling. Before the electroplating process is carried out, it is necessary to eliminate the oil stains on the surface of the parts, and the actual effect of degreasing will immediately endanger the quality of the electroplating process. The vegetable oil on the surface of the product workpiece is mainly a variety of nitrogen oxides, some of which do not reflect with alkali and cannot soap foot, so it is called non soap foot oil. The removal of this kind of oil can only be done with emulsion or melting effect; Other oils and alkalis produce soap foot effect, which is called soap foot oil. This kind of oil can be removed according to soap foot, emulsion and melting effect. Common degreasing methods include physical mechanical degreasing, solvent degreasing, organic chemical degreasing, photoelectric catalytic degreasing and the synergistic method of the above methods.
With the parts as anode oxidation or negative electrode, the photocatalytic degreasing is in alkaline solution. Stainless steel plate, nickel plate, nickel plated thick steel plate or titanium plate are selected as the second level, and the whole process of removing oil stains on the surface of parts under the effect of DC power supply. Photoelectric catalytic oil removal is similar to alkaline organic chemical oil removal, but its key is to enhance the actual effect of oil removal by virtue of the effect of electrolysis. Generally, photoelectric catalytic oil removal is more reasonable, faster and more complete than organic chemical oil removal.
