Abstract

The invention relates to an innovation method of an anodized negative plate. The innovation method is characterized in that tops of bristles of an irregular rotary negative plate follow brush are attached to the surface of the negative plate, and the negative plate stably rotates in ananodizingbath solution at a constant speed; the shape of the negative plate is a groove-shaped rotary body, a sine wave rotary body or a sawtooth-shaped rotary body; the bristles of the follow brush are made of PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy alkane), PP (polypropylene), PE (polyethylene), PS (polystyrene), carbon fibers, glass fibers, basalt fibers, aramid fibers or polyester fibers; the rotating speed of the negative plate is 1-12 r / min. According to the innovation method, the area of the anodized negative plate is effectively increased, bubbles and impurities on the surface of the negative plate are reduced, so that the utilization rate of the negative plate is increased, current density of a workpiece is uniform, thickness and performance of an oxide film are uniform, and the service life of the negative plate is prolonged; the method is also suitable for micro-arc oxidation.

Description

technical field [0001] The invention relates to an innovative method for cathode plates, in particular to an innovative method for anodizing cathode plates. Background technique [0002] Anodizing belongs to the electrochemical conversion film technology in the field of material surface engineering. Its essence is that a dense oxide film is formed on the surface of aluminum, magnesium, titanium and other workpieces through electrochemical action, which endows the surface of the workpiece with high hardness, high corrosion resistance and high insulation. Physical and chemical properties, so a wide range of applications. However, in the actual production of anodic oxidation, there are still a series of technical problems to be overcome, such as: a large amount of waste products due to uneven oxide film and inconsistent performance, and the regular impurity removal cleaning of the cathode plate makes the production efficiency low. [0003] An important factor affecting the thi...
