Aluminum alloy plate surface oxidation treatment process

Abstract

The invention relates to the technical field of die-casting aluminum alloy oxidation, in particular to an aluminum alloy plate surface oxidation treatment process. The aluminum alloy plate surface oxidation treatment process comprises the steps that a driving motor in oxidation treatment equipment is started, the driving motor drives a threaded rod to rotate in a reciprocating mode, and a mounting column reciprocates along the threaded rod, so that a aluminum alloy plate is clamped by a clamping plate at the bottom of the mounting plate for scheduling in an electroplating chamber and a heating chamber. According to the aluminum alloy plate surface oxidation treatment process, after the aluminum alloy plate is clamped by the clamping plate, the aluminum alloy plate is placed in the electroplating chamber for electroplating, an electrolyte can electroplate the aluminum alloy plate in the electroplating chamber, an air inlet fan is started to enable an inner ring pipe and an outer ring pipe to blow the electrolyte, the flowing speed of the electrolyte is increased, the oxidation efficiency of the aluminum alloy plate is improved, and the airflow blown by the outer ring pipe can drive a stirring wheel to rotate, so that the flowing rate of the electrolyte is further improved.

Description

technical field [0001] The invention relates to the technical field of die-casting aluminum alloy oxidation, in particular to an oxidation treatment process for the surface of an aluminum alloy plate. Background technique [0002] The oxidation coloring of aluminum refers to the use of artificial methods to form an oxide film on the surface of aluminum and its alloy products and apply different colors to improve the wear resistance of aluminum materials, prolong the service life and increase the beautiful color. The basic process of oxidation coloring is aluminum surface treatment, oxidation, coloring and subsequent hydration sealing, organic coating and other treatment processes. The surface of aluminum oxide maintains an oxide film of 10-100 angstroms under natural conditions, and the artificial oxide film controls the film thickness at 0.5-250 microns according to different purposes. The methods of artificial film formation include chemical oxidation and electrochemical ...

Problems solved by technology

However, the existing aluminum alloy plate oxidation treatment device cannot oxidize the surface of the aluminum alloy plate in large quantities during use, so that the efficiency of the aluminum alloy shell oxidation treatment is low, and the positioning structure of the existing oxidation treatment device cannot allow The user can flexibly adjust according to the size of the aluminum alloy shell, and the freedom of electrolyte flow is not good, resulting in low oxidation efficiency
