Innovation method of anodic oxidation cathode plate

　　Anodic oxidation is a kind of electrochemical conversion coating technology in the field of material surface engineering. Its essence is to form a dense oxide film on the surface of aluminum, magnesium, titanium and other workpieces by electrochemical action, which makes the surface of the workpiece have high hardness, high corrosion resistance and high insulation. Due to its physical and chemical properties, it has been widely used.

The cathode plate and the top of the bristles are connected on the surface of the cathode plate, and the cathode plate rotates uniformly and stably in the anode oxidation tank. This innovative method of anode oxidation of the cathode plate can not only effectively increase the area of the cathode plate, but also timely remove the bubbles and impurities on the surface of the cathode plate, and solve the problem of uneven thickness performance of the oxide film caused by the existing cathode plate Problems.

Aluminum, lead or stainless steel cathode materials are made into trough rotating body, sine wave rotating body or zigzag rotating body cathode plate. The cathode plate is installed on the inside of the oxidation tank. The cathode plate is made of polytetrafluoroethylene, PFA, PP, PE, PS, carbon fiber, glass fiber, basalt fiber, aramid fiber or polyester fiber. The brush hair is attached to the outer surface of the cathode plate.

The workpiece is clamped for anodizing, and the cathode plate rotates at a constant speed of 1-12r / min in the bath. After anodizing, stop the rotation of the cathode plate and take out and clean the workpiece.
