Anodowane aluminium w kolorze czerwonym

Ⅰ: anodowana blacha aluminiowa.

Ⅰ-a: Co to jest anodowanie.

Produkty z aluminium lub stopów aluminium jako anoda, umieszczone w roztworze elektrolitu w celu obróbki elektrycznej, zastosowanie elektrolizy do wytworzenia powierzchni procesu tworzenia folii z tlenku glinu, znane jako anodowe utlenianie aluminium i stopów aluminium.

Ⅰ-b: Zasada kolorowania.

The chemical coloring of aluminum anodic oxidation film is based on the adsorption capacity of the porous film layer. The pore diameter of general anodic oxidation is 0.01-0.01um, and the dye is separated into single molecules in water with a diameter of 0.0015-0.0030um. The coloring is that the dye is adsorbed on the pore surface and diffused into the pore and accumulated. And the aluminum oxide ionic bond, hydrogen bond combination and make the film color, the hole sealing treatment, the dye is fixed in the pores.

Ⅰ-ok: Anodized color of industrial aluminum profiles.

The anodizing of industrial aluminum profiles have a decorative effect. In the process of anodizing, the color you want to make is optional, takie jak czarny, silver-white, czerwony, i tak dalej.

Ⅰ-d: Application field.

Anodized aluminum plate is widely used in architectural decoration, meble, and home appliances.

1, architectural decoration industry such as building facade, ściana osłonowa, indoor wall top surface, itp.

2. In the field of furniture and home appliances, the anodized aluminum plate is a favorite decorative panel for manufacturers.

Ⅱ: What is the color process of anodic oxidation of aluminum？

Ⅱ-a: Anodized hole sealing process for aluminum profiles.

(1) High-temperature water sealing this method uses the hydration reaction between the alumina film and water to transform the amorphous film into a hydrated crystalline film: the hydration reaction can be carried out at room temperature and high temperature, but the hydrated crystalline film is generated at high temperature, zwłaszcza w temperaturze wrzenia, is a very stable and irreversible crystalline film. Dlatego, the most common sealing method of alumina film is the boiling water method or steam method.

(2) inorganic salt sealing inorganic salt method can improve the fastness of organic coloring dyes, so it is often used for chemical coloring methods. ① Acetic acid method ② Silicate method.

(3) organic sealing method, to jest, oil immersion method, paint immersion method, or alumina film coating method. Because of the high cost and many processes, it has not been widely used. Most of the above two methods are adopted, and the two high-temperature water methods are the mainstream.

Ⅱ-b: Anodic oxidation coloring process of aluminum alloy.

(1) Anodic oxide film can be naturally colored. In the process of electrolysis, adjust the parameters of alumina, so that iron, mangan, and other elements oxidation, and then add metal salts or other acids in the plating solution, to jest, the color of the oxide film.

(2) electrolytic coloring, electrolytic coloring liquid is mainly nickel salt and tin salt, nickel tin mixed salt. Other industrial applications include iron, mangan, copper salt, itp., and the color is mainly light and dark bronze. Dates and other colors, but not much. Jednakże, electrolytic coloring is very stable and resistant to sunlight. Mimo wszystko, it's salt and inorganic. It is widely used in building profiles. It's not colorful. It does not form the common oxide film colors of cameras, telefony komórkowe, and alpenstock.

(3) Dyeing methods also need to obtain such porous membranes. After cleaning directly into the tank containing dye, dye adsorption on the hole wall. This requires high porosity and adsorption activity on the inner wall of the pore. Dlatego, we are still doing more research on the sulfuric acid oxide film. The pore size of the sulfuric acid oxide film is relatively large and the color is relatively transparent, so it is easy to obtain a purer dyeing film.
