Problems solved by technology

[0003] At present, the more mature one is ordinary sulfuric acid decorative anodizing. The film pores formed by ordinary sulfuric acid decorative anodizing are honeycomb, and the hardness is far inferior to that of ceramic anodizing. The existing aluminum alloy anodizing process is as follows: Machining materials (Aluminum alloy materials include 1000 series, 5000 series, 6000 series, 7000 series) - cleaning - drying - sandblasting - hanging - degreasing - chemical polishing - neutralization - ordinary anodizing - dyeing - sealing - drying, the most common The dyeing of aluminum alloy anodic oxidation film is chemical dyeing and electrolytic coloring of sulfuric acid anodic oxidation film layer, and sealing treatment must be carried out after dyeing or coloring, and there are many processes
And the current industry is in the anodic oxidation of aluminum alloy shells in the 3C industry. The disadvantage is that there is no way to achieve a high-gloss glaze effect on the surface of the product, and there is no way to achieve high hardness, high glaze, anti-scratch, and acid resistance in product functional testing. Alkali, vibration grinding and UV / salt spray resistance and other functions

The process includes the following steps of (1) machining of the aluminum alloy, (2) three-stage polishing, (3) sleeking, (4) racking, (5) cleaning, (6) drying, (7) sand blasting, (8) racking, (9) degreasing, (10) chemical polishing, (11) neutralization, (12) whitening, (13) neutralization, (14) ceramic anodizing, (15) dyeing and hole sealing, (16) drying, (17) C-angle highlighting, (18) racking, (19) degreasing, (20) neutralization, (21) ceramic anodizing, (22) dyeing and hole sealing, and (23) drying. The machined product is polished into a smooth surface similar to a mirror surface, so that basic requirements of the smooth glaze surface are met; then the matted or frosted effect is achieved through the sand blasting process, so that viewing angle requirements of customers are met; by means of the method that the basic brightness of the sand surface is improved through the chemical polishing principle, preparations are made for the frosted ceramic anodizing process; products with frosted and matted glazes are produced through the ceramic anodizing process, the color fastness of an oxidation film is improved, and the good functions of abrasion resistance, corrosion resistance and weather resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of anodic oxidation technology, in particular to the anodic oxidation technology of aluminum alloy frosted glazed ceramics. Background technique [0002] With the widespread use of aluminum alloy in the current 3C industry, as well as the advancement of science and technology and the improvement of people's living standards, the aesthetics have undergone significant changes, and its surface treatment technology has also developed rapidly. Among aluminum alloy surface treatment technologies, anodic oxidation technology is currently the most widely used and most successful. Anodizing is an electrolytic oxidation process in which the surface of aluminum alloys is usually converted into an oxide film. This oxide film has protective, decorative, and some other functional properties. Anodizing technology is a reliable metal surface treatment process. It guarantees consistent gloss and color of the material in t...
