Abstract

The invention discloses an aluminum oxidation coloring device, and belongs to the technical field of aluminum oxidation equipment. The aluminum oxidation coloring device comprises a coloring groove, a power source, a first acceleration set and a second acceleration set, a first division plate and a second division plate are arranged on the upper wall in the coloring groove, and the first division plate and the second division plate divide the upper part of the inner side of the coloring groove into a first anode part, a cathode part and a second anode part in sequence. A first acceleration area and a second acceleration area are arranged on the lower part of the inner side of the coloring groove. The first acceleration set enables ions horizontally moving in the first acceleration area to obtain upward acceleration and to drive away from the first acceleration area to a target electrode in an acceleration mode, and the second acceleration set enables ions horizontally moving in the second acceleration area to obtain upward acceleration and to drive away from the second acceleration area to a target electrode in an acceleration mode. According to the aluminum oxidation coloring device, the horizontal moving ions in coloring liquid can obtain the acceleration of upward movement through acceleration of a magnetic field, the speed of reaching the target electrode is increased, meanwhile, vertical moving ions can obtain the acceleration of vertical movement through acceleration of the electric field, and the speed of reaching the target electrode is increased.

Description

technical field [0001] The invention belongs to the technical field of aluminum oxidation equipment, and more specifically relates to a coloring device for aluminum oxidation. Background technique [0002] After aluminum is anodized in sulfuric acid solution, an oxide film is formed on the surface of the product. The outermost surface of this oxide film is porous and is called a porous layer. The bottom layer of the oxide film is in contact with the aluminum substrate, which is a dense thin oxide film layer, also known as the active layer or barrier layer. The aluminum material with anodized film is immersed in the electrolyte of some metal salt and used as an electrode (because of alternating current), while the other electrode can be made of the same pure metal plate or metal salt contained in the electrolyte. Graphite, stainless steel plate, etc. When the two poles are connected with alternating current at the same time (generally under the conditions of low voltage and...
