The applications of anodized aluminum sheet in industry

(1) anodized aluminum sheet to prevent corrosion of products:

the anodic oxidation of the film through the appropriate closed treatment, in the atmosphere have good stability. Whether it is from the sulfuric acid solution, oxalic acid solution or chromic acid solution in the normal process to obtain the oxide film, the corrosion resistance is very good, such as daily aluminum pan, pot, washing machine liner and so on. Chromic acid oxidation is particularly suitable for aluminum welding and riveting pieces.

(2) anodized aluminum sheet protection of a decoration:

 in the transparency of the oxide film, the oxide film can be adsorbed with a variety of organic dyes or inorganic pigments, the oxide film can be a variety of bright and bright colors and patterns, plus in recent years not The emergence of new technology such as the oxidation of a number of times the coloring, fireworks patterns, grain patterns, oxidized offset printing transfer, porcelain oxidation, etc. 182Aluminum appearance more beautiful and pleasing to the eye, this layer of color film is both decorative layer, but also anti-corrosion layer, such as lighter. Gold and handicrafts.

(3) anodized aluminum sheet as a hard wear layer:

in sulfuric acid or oxalic acid solution can be adjusted by anodizing process conditions, to obtain thick and hard film, the use of membrane hole and absorption properties to store the selected oil, Effectively applied to the friction conditions of the work conditions, but also with lubrication and wear characteristics, such as cars and tractors engine cylinder, piston and so on.

 (4)anodized aluminum sheet as the electrical insulation layer: 

aluminum and its alloy oxide film has a large resistance characteristics, the thickness of the film is proportional to the resistance, this feature as the electrical insulation has a certain practical significance, can be used as a capacitor Of the dielectric, you can also use aluminum oxide as the outer envelope of the cable, for its surface as an insulating layer to replace the plastic foreskin and plastic foreskin in foreign countries is more popular, the film thickness of 27.5 mm, the wear voltage of 441V. If the use of phenolic resin for film hole filling, the wear resistance can be increased by 2 times in the oxalic acid solution, when the film thickness increases, you can get resistance 200fl, breakdown voltage of 980V high-quality insulation, of course, the use of this feature In addition to the use of wire, but also can be used for other electrical appliances and so on.

(5)anodized aluminum  sheet for painting, plating the bottom:

 the oxide film layer with a porous and good adsorption capacity, and the film and organic film has a good binding force, can be used as the bottom of the paint. A layer of phosphoric acid anodized can be used as an undercoat for aluminum plating.

(6)anodized aluminum for the modern building: 

the introduction of aluminum alloy electrolytic coloring process, in recent years, domestic electrolytic coloring used in building aluminum is increasing, it is not only suitable for architectural tones of bronze, black, red, In general conventional oxidation, it is particularly worth mentioning that the light fastness is very good, more than 20 years sun drying dew in the air without color, which is unmatched with the oxidation coloring method. Electrolytic coloring of the oxidation of aluminum can not only be used for building doors and windows, use it to do shop counters, shelves, etc. is also particularly appropriate.
