Embodiment Construction

[0015] An anodizing process for an embossed aluminum plate, including putting on the shelf—degreasing—washing—alkali etching—washing—neutralization—washing—anodizing—washing—sealing—washing—off the shelf—detection—packaging, the anodizing:

[0016] (1) Alkali washing with alkaline washing solution at 40-90°C for 5-11 minutes to remove organic grease and inorganic carbides on the surface of the workpiece;

[0017] (2) Sulfuric acid neutralization: pickling with pickling solution at room temperature for 3-12 seconds;

[0018] (3) Chemically polish with polishing liquid at 100-105°C for 4-5 minutes to make the surface of the workpiece smooth and bright;

[0019] (4) Illumination: Use nitric acid solution at room temperature to remove oxide skin or insoluble matter on the surface of the workpiece for 5-10 seconds, so that the crystal layer is exposed on the surface of the workpiece;

[0020] (5) Anodizing: use anodic oxidation electrolyte, under the conditions of temperature 15-2...

Abstract

The invention relates to the technical field of aluminum plate oxidation, in particular to an embossed aluminum plate anodizing process. The embossed aluminum plate anodizing process comprises the steps of loading of an aluminum plate on a rack, degreasing, washing, alkali corrosion, washing, neutralizing, washing, anodizing, washing, hole sealing, washing, unloading of the aluminum plate off the rack, detecting and packing. The aluminum plate produced through the embossed aluminum plate anodizing process has the advantages of being resistant to abrasion and corrosion, simple in production process, convenient to control and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of aluminum oxidation, in particular to an anodic oxidation process for an embossed aluminum plate. Background technique [0002] Alumina plates are widely used in refrigerator refrigeration, mechanical parts, aircraft, automobiles, precision instruments, radio equipment, building shells, machine shells, electronic consumer goods, household appliances and other industries. It has the characteristics of bright, smooth, anti-corrosion, and anti-oxidation. Chemical performance is stable. In the prior art, the anti-corrosion treatment on the surface of the aluminum plate mostly adopts the method of spraying paint. The aluminum plate after the oxidation treatment is not very good in corrosion resistance, and the paint also pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide an anodic oxidation process for embossed aluminum plates, which overcomes the d...
