The Principle of Electrolytic Polishing Stainless Steel:
Electrolytic polishing is mainly through the negative current, electrolyte with total action down to improve the micro shape of the metal surface, and reduce the metal surface roughness, to achieve the purpose of the workpiece surface brightness level.
Electrolytic polishing, first of all, the main feature of selective dissolution, surface wave curve, from the microcosmic point of view is the part of the metal surface; gets an electricity rate than the concave part of the electricity rate is higher, so the protruding parts will be dissolved, and recessed parts because of the mucosa is more, low power, so the passivation status, it is not easy to be dissolved. So the early stages of the electrolytic surface are the whole process. After being smooth then slowly into the process of light, the light is a flat and level surface.
Electrolytic Polishing Stainless Steels
Scope of Application:
This product is suitable for electrolytic polishing brightness in all stainless steel materials. Especially for electric polishing solutions in the process or material sort is more users the most practical. Such as furniture, tableware, door flowers, pipes, wire rods, shelves, stamping parts, and various metal parts inside and outside the polishing, the applicable scope is extremely broad.
Operating Procedures:
Hang on to chemical degreasing, hot water wash to wash in cold water, electrolytic polishing to secondary flow cold water washing, acid activation (5 ? acid aqueous solution) to flow of cold water to wash, dry (can be adjusted according to actual condition, part of the process).
Method of Use:
Concentrate, lead plate for the cathode (negative), do the anode (the anode) artifacts, 40 degrees, the current density of 10 to 25 amps/square decimeter, 8-10 v, 5 to 8 minutes. Recommended process: (degreasing de-rusting activation to washing to dry out), electrolytic polishing, washing – passivation – water – and – washing
Precautions for Electropolishing
1. The working fluid is corrosive and should not be in contact with bare skin. Latex gloves should be worn during the operation.
2. When the oil pollution of the treatment parts is serious, it is recommended to pre-make rough waste oil removal.
3. After the working fluid has been treated for some time, due to the decrease in the effective concentration, the treatment effect is not good. At this time, the new fluid should be replaced or the product should be supplemented. Other products of the company;

Polishing Process Definition
Electrolytic polishing machine with electrolyte, electrolytic cell, electrolytic power supply, lead plate, heating tube, stainless steel, copper, aluminum, and other metal polishing processing, to beautify the metal surface, as to achieve the mirror effect of the metal surface.
Electrolytic polishing is mainly used in stainless steel products of bicycle accessories, doors and windows, hardware accessories, pipes, medical equipment, water treatment equipment, and other fields, especially for some special parts, mechanical polishing cannot operate artifacts and has very good substitution. In industrial production, the polishing technology of electrolytic polishing is very widely used, through continuous development, electrolytic polishing technology is mature, whether in the brightness or application areas, and has reached unprecedented levels.

Advantages of Electrolytic Polishing
1. High Surface Finish
Electrolytic polishing can make the surface of stainless steel present a mirror effect, greatly improving the appearance quality of the product, especially suitable for decorative products.
2. Improved Corrosion Resistance
The surface oxide layer after polishing is more uniform, effectively enhancing the corrosion resistance of stainless steel, especially suitable for food, chemical, and pharmaceutical fields.
3. No Mechanical Damage
Unlike mechanical polishing, electrolytic polishing will not leave scratches on the surface, suitable for the surface treatment of precision parts.
4. Suitable for Complex-Shaped Workpieces
Whether the workpiece is a complex geometric shape or has tiny holes, electrolytic polishing can achieve uniform treatment.
5. Improved Cleaning Performance
The smooth surface does not easily adhere to dirt and bacteria, which is very suitable for food processing equipment, pharmaceutical equipment, and medical devices.
