Embodiment Construction

[0026] The technical solutions of the present invention will be further described below through specific embodiments.

[0027] The natural alumina on the surface of aluminum products is soft and thin, and has poor corrosion resistance. It cannot be an effective protective layer and is not suitable for coloring. Therefore, in modern industry, an artificial oxide film is made on the surface of the product as a protective film on the product surface. Compared with natural alumina, it has better corrosion resistance, good hardness, large thickness and good coloring.

[0028] After the aluminum alloy is anodized, it can present a strong metallic texture, and the colors are various. However, the surface of the products produced by ordinary anodizing has a flat effect, and the coloring is relatively single and dull. At the same time, it is easy to produce scratches during use, so the products have no diversity and appear to be the same.

[0029] For this reason, the present inventio...

Abstract

The invention relates to the technical field of electronic equipment, in particular to a 3D effect surface treatment process. According to the 3D effect surface treatment process, anodic oxidation is carried out after the surface of an aluminum alloy is subjected to shielding sand blasting for two times at least by a shielding jig on the basis of conventional sand blasting. Through at least two times of sand blasting by the shielding jig, sand thicknesses and pressures of adjacent patterns are different, structure layers of surfaces of products are enriched, and through anodic oxidation, the 3D effect is achieved. Products manufactured by the process have excellent metallic appearance, are good in smudginess resistance, and are quite suitable to be used as appearance products of electronic and communication equipment.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a 3D effect surface treatment process. Background technique [0002] The natural alumina on the surface of aluminum products is soft and thin, and has poor corrosion resistance. It cannot be an effective protective layer and is not suitable for coloring. Therefore, in modern industry, an artificial oxide film is made on the surface of the product as a protective film on the product surface. Compared with natural alumina, it has better corrosion resistance, good hardness, large thickness and good coloring. [0003] The artificial oxide film is mainly applied chemical oxidation and anodic oxidation. Chemical oxidation is a treatment process in which part of the base metal of aluminum products reacts in a weakly alkaline or weakly acidic solution to thicken the natural oxide film on the surface or produce other passivation films. [0004] Compared with the anodic oxid...
