Color Coated Aluminum Plate

Color-coated aluminum plate is also called color aluminum plate, also known as organic coated plate or pre-coated aluminum plate. The color-coated aluminum plate is a composite material formed by coating one or more layers of organic coatings on the surface of the aluminum substrate after passing through the color coating unit and baking and curing. Color-coated aluminum sheets have the advantages of both aluminum sheets and organic materials. It not only has the advantages of high mechanical strength, good toughness, and easy processing and molding of aluminum plates, but also has the advantages of good coloring, decoration and corrosion resistance of organic polymer coating materials. It can be easily processed such as punching, bending, deep drawing, welding, etc. The products made are practical, suitable for decoration, easy to process and durable. At GangHua Steel, we can produce color-coated aluminum sheets of various specifications, models and colors. As a professional manufacturer and supplier, we insist on providing customers with high-quality products. Welcome to contact us!

Coating Process Of Color-Coated Aluminum Plate

Color aluminum plate has topcoat, primer and backcoat. The back coating mainly plays an anti-oxidation effect. The specific coating process includes the following aspects, semi-finished products - upper machine - forming - lower parts and inspection - packaging and storage, and coating the surface of the aluminum plate can prolong the service life of the color aluminum plate longer.

The color aluminum plate is made by rolling the high-quality paint on the surface after the necessary degreasing and chemical treatment on the surface of the aluminum plate, and the paint is dried and cured on the surface of the aluminum plate. The flatness of the paint film on the surface of the roller coated plate is higher than that of the sprayed plate. The color is divided into pearlescent and matte. The most common ones on the market are pearlescent, and its price is higher than that of spraying. The biggest feature of the roller coating board is the extremely high degree of color simulation; the quality of the roller coating process is very different, in addition to all the materials, it is also related to the coloring in several times, such as two coats and two rollers, It is to spray once and bake once, and then spray and bake again, so that the color is more uniform and smooth.

Imported fluorocarbon roller coating is also a kind of roller coating, which is to add fluorocarbon to the pigment, which makes the color adhesion stronger, the service life is longer, and it is resistant to acid, alkali and corrosion. It is often used in the exterior decoration of buildings (not afraid of wind). Blowing rain), the price and cost are very high, and it is the most high-grade type of roll-coated sheet.

Aluminum Plate Oxidation Coloring Method

• Chemical coloring: The oxidized aluminum material is immersed in an organic or inorganic dye solution, and the dye penetrates into the pores of the oxide film and is colored by chemical or physical action. The chemical coloring equipment is simple, the cost is low, and there are many kinds of colors, but the light resistance and corrosion resistance are poor, and it is only suitable for interior decoration.

• Electrolytic coloring: The oxidized aluminum material is subjected to secondary electrolysis in a single metal salt or a variety of metal salt aqueous solutions. Under the action of an electric field, metal cations penetrate into the pores of the oxide film and deposit on the bottom of the pores. Make the oxide film produce bronze, brown, gray and red, cyan, blue and other tones.

• Natural coloring: A method of coloring aluminum while anodizing. There are alloy coloring method and solution coloring method. The alloy color development method is to control the composition of the aluminum alloy to obtain different hues; the solution color development method, also known as the electrolytic color development method, is to control the composition of the electrolyte and the electrolysis conditions to control the hue. In actual production, organic acid is generally used as the electrolyte for natural coloring, and a small amount of sulfuric acid is added to adjust the PH.

• For the oxidation and coloring of aluminum：An oxide film (Al₂O₃) is formed on the surface of aluminum and its alloy products by artificial methods, and different colors are applied to improve the wear resistance of aluminum materials, prolong the service life and increase the color and luster. The basic process of oxidation coloring is aluminum surface treatment, oxidation, coloring and subsequent hydration sealing, organic coating and other treatment processes.

Application Of Color Aluminum Plate

Color-coated aluminum plate has high decorative and corrosion resistance, so it is widely used in electronic appliances, food, construction, transportation and other fields, and the market demand is high. According to the different coatings used, color-coated aluminum can be divided into high-end fluorocarbon color coatings and relatively low-end polyester color coatings.

Selection Skills Of Color Aluminum Plate

The surface of the high-quality color aluminum plate is uniform, smooth, and has no obvious defects such as missing coating, shrinkage holes, scratches, and falling off. However, there are trace defects such as bubbles, pits, and inclusions, which are normal phenomena.
