1. Electropolishing definition

   Electrolytic polishing is also known as electrochemical polishing. The workpiece to be polished is an anode insoluble metal as a cathode. The two poles are simultaneously immersed in the electrolytic cell, and a direct current is generated to generate a selective anode dissolution, thereby increasing the brightness of the surface of the workpiece.

2, the principle of electropolishing

The principle of electrolytic polishing mainly has the theory of mucosa as the basic theory. The theory is mainly: the metal ions detached from the workpiece and the phosphoric acid in the polishing solution form a phosphate film adsorbed on the surface of the workpiece. The mucosa is thinner at the convex portion, and the concave portion is thicker because the current density at the convex portion is high. The dissolution is fast, the mucous membrane flows, and the irregularities are constantly changing, so that the rough surface of the workpiece is gradually leveled.

3, electropolishing characteristics

(1) The color inside and outside is consistent, the gloss is long-lasting, and the recess that can not be thrown by mechanical polishing can be leveled.

(2) High production efficiency and low cost.

(3) increase the surface corrosion resistance of the workpiece

4 can remove the burr on the surface of the part

5. The surface of the workpiece after electrolysis is not easy to form garbage and breed bacteria.

Environmentally friendly general electrolyte features

1. The polishing solution does not contain chromium ions, which meets the current environmental protection requirements, saves investment in environmental protection equipment and low cost of wastewater treatment; can pass ROSH certification

2. The polishing current density is small, the voltage is low, and the power consumption is more than 1 times lower than the conventional process;

3, high polishing efficiency, good quality, can be thrown to the mirror bright effect within a few minutes;

4, the polishing fluid has a long service life and is easy to maintain and manage.
