Material treatment method

Abstract

The invention provides a material treatment method. The material treatment method comprises the anode oxidation step and further comprises an anodic treatment method. The anodic treatment method is implemented before the anode oxidation step and comprises the following steps of conducting primary sand blasting treatment on a base material; conducting primary pretreatment on the material subjectedto primary sand blasting treatment; conducting primary chemical polishing treatment on the material subjected to primary pretreatment; adding a shielding part to the material subjected to primary chemical polishing treatment; conducting secondary sand blasting treatment on the material with the shielding part and removing the shielding part; conducting secondary pretreatment on the shielding partremoved material subjected to secondary sand blasting treatment; conducting secondary chemical polishing treatment on the material subjected to secondary pretreatment and adjusting the proportional relation between the secondary chemical polishing treatment time and the primary chemical polishing treatment time according to the demand of glossy-matt comparison. Through the material treatment method disclosed by the invention, glossy-matt distinguishment can be realized in different areas; the glossy-matt areas are uniform and consistent in hand feeling; sand blasting textured glossy-matt areasare consistent in density, and no bottom missing phenomenon occurs.

Description

technical field [0001] The invention belongs to the field of material processing technology, and particularly relates to a material processing method. Background technique [0002] At present, through a single process, ordinary sandblasting anodizing cannot achieve the effect of forming different brightness and color separation on the surface of the aluminum material to be treated. It can be seen that, in the prior art, the sandblasted anode products after anodizing treatment usually exhibit a monotonous effect, lack variability, and cannot meet the increasing personalized demands. [0003] In addition, although there are currently some anodizing treatment methods, for example, spraying different types of sand molds in different areas, and distinguishing bright fog by adjusting different types of sand molds or the intensity of sandblasting. However, this treatment method has corresponding problems. For example, due to the fine sand mold and the small blasting force, the sub...

AI Technical Summary

Problems solved by technology

However, there are corresponding problems in this treatment method. For example, due to the fine sand mold and low sandblasting force, the bottom material will be exposed in the high-gloss area, and the defects of the aluminum plate itself cannot be perfectly covered.

In particular, after using different sand types for sandblasting, the overall feel of the sandblasting anode products will have a difference in roughness, and the effect of uniform feel cannot be achieved, which also reduces the user experience accordingly
