Processing Technology and Characteristics of Color-coated Aluminum Coil

Color-coated aluminum coils, as the name suggests, is to paint and colorize the surface of aluminum substrates. The common ones are fluorocarbon color-coated aluminum coils and polyester color-coated aluminum coils, widely used in aluminum-plastic panels, industrial factory walls, aluminum shutters, composite panels, aluminum ceilings, pop-top cans, and electronic products.


Ⅰ. Processing technology of color-coated aluminum coil


1. After the light aluminum coil is cleaned, chromed, rolled, baked, etc., the surface of the aluminum coil is coated with various colors of paint, that is, the color-coated aluminum coil.


2. Color aluminum is widely used in thermal insulation boards, aluminum curtain walls, aluminum magnesium manganese roofing systems, aluminum ceilings and many other fields because of its light texture, bright color, easy processing and no rust.


3. Pre painted aluminum coil can be simply divided into: surface-coated paints, divided into polyester-coated aluminum coils and fluorocarbon-coated aluminum coils; epoxy roller-coated aluminum coils. Of course, there are also cases where one side is coated with fluorocarbon and the other side is coated with polyester; there are even cases where both sides are coated with fluorocarbon.


4. The thickness of the coating can be divided into single coating, double coating and three coating; the surface patterns are various, also known as wood grain aluminum coil, stone grain aluminum coil, brick pattern, camouflage aluminum coil, fabric aluminum coil, etc.; because Different uses, also usually become roofing material (aluminum-magnesium-manganese roofing system), ceiling material (for aluminum alloy ceiling), wire drawing board (the surface is brushed) and so on.


Ⅱ. The main characteristics of color-coated aluminum coil


1. Good temperature resistance, the melting point of aluminum is 660 degrees, and the general temperature cannot reach its melting point.


2. It is environmentally friendly and not easy to change color. It is operated with a chromium-free treatment solution; the roller coating paint contains active chemical molecules, which promotes the formation of a protective layer on the surface of the material. The active chemical molecules are stable and easy to recycle, meeting environmental protection requirements.


3. Corrosion resistance Because there is a tight oxide film on the surface, it has strong adhesion, oxidation resistance, strong acid and alkali resistance, corrosion resistance, decay resistance, ultraviolet radiation resistance and other characteristics.


4. The color is uniform and long-lasting, and the color is uniform and delicate. Soft and bright, it avoids the individual chromatic aberration of traditional spraying. No matter how large the ceiling is, its color and luster are consistent and long-lasting.


5. Combination of rigidity and toughness, the strength of the board is extremely high. The combination of rigidity and toughness can be arbitrarily cut, slit, curved, pressure balanced, drilled, connected and fixed and edge compression formed.


Color-coated aluminum coil has a rich color range, whether it is a residential residence, a large commercial network or a large-scale exhibition center, the color-coated aluminum coil can add color to it. Good plasticity and machinability make it an ideal material for various architectural shapes. Color-coated aluminum coils have provided architects, designers and owners with a color space to achieve personalized exterior walls and ceilings, and it is also the most ideal material for architectural modeling. Whether it is a multi-functional large building or a unique and creative new building, the color-coated aluminum coil can always meet the different requirements of modern and classical architectural styles, and make the building colorful. Products are used in many fields such as electronic appliances, instruments, lighting, packaging, home improvement and so on. As a professional color coated steel coil manufacturer in China, Easteel has rich experience in high-quality color-coated aluminum coil manufacturing.
