Introduction of coated aluminum coil:

Coated aluminum (coated aluminum coil), as the name implies, is the surface coating coloring treatment of aluminum plate or (aluminum coil), common with fluorocarbon coated aluminum (coated aluminum coil), polyester coated aluminum (color coated aluminum) Volume), widely used in aluminum composite panels, aluminum veneers, aluminum honeycomb panels, aluminum ceilings, roofing surfaces, trims, cans, electronic products. Its performance is very stable, not easy to be corroded, the surface layer can be 30 years of quality assurance after special treatment, and the weight per unit volume is the lightest of the metal materials, coated aluminum, is the most popular new material.

Coated aluminum coil type:

The coated aluminum coil coating is divided into: polyester coated aluminum coil (PE), fluorocarbon coated aluminum coil (PVDF). The polyester coating formed by multiple baking of the surface of the aluminum plate can form a firm adhesion. The continuous solid film has protective decorative properties. It is an anti-UV ultraviolet coating. The polyester resin uses a polymer containing an ester bond in the main chain as a monomer, and an alkyd resin is added. The ultraviolet absorber can be divided into a matt and a high-gloss series according to the gloss. It can give rich color to color aluminum products, and has good gloss and smoothness, as well as superior texture and hand feeling, and can also add layering and three-dimensionality. Protected objects exposed to the atmosphere, exposed to ultraviolet radiation, wind, rain, frost and snow; coatings can protect against temperature, freeze-thaw cycles, corrosive gases and microorganisms. Especially suitable for interior decoration and advertising panels.

Fluorocarbon coated aluminum coil (PVDF)

The fluorocarbon coating is a coating of PVDF resin mainly referring to a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and other small amount of fluorine-containing vinyl monomer. The chemical structure of the fluoric acid base is combined by a fluorine/carbon bond. This chemical structural stability and firmness make the physical properties of fluorocarbon coatings different from conventional coatings. In addition to the abrasion resistance in terms of mechanical properties, impact resistance has excellent performance, especially in harsh weather and environment, showing long-lasting resistance to fading and UV. After the high temperature barbecue is formed into a film, the molecular structure of the coating is tight and has excellent weather resistance. Fluorocarbon coatings can be classified into conventional fluorocarbon and nano fluorocarbon coatings according to the surface film formation structure. In 1965, Pennwalt Chemical Company first used fluorocarbon coatings to meet the indoor and outdoor aluminum coatings of high-grade buildings. The choice of a wide range of colors, the solemn appearance of the United States, and durability have added brilliance to many magnificent curtain wall buildings around the world. Coating manufacturers\' guarantees for coating life have been developed for 10 years and 15 years to be guaranteed for more than 20 years. American research institutes have tested and compared fluorocarbon coatings and super-coatings and general coatings. The coated samples were placed in hot sunlight in Florida, USA, and exposed to the harsh environment of humid salty air. In the year, it was proved that the stability and durability of fluorocarbon coatings were 30 and 80% higher than those of the other two coatings, and fluorocarbon coatings were guaranteed to be used in various harsh environments.

It is especially suitable for the decoration and display of indoor, outdoor decoration, commercial chain, exhibition advertisements, etc. in public places.

Coated aluminum coil features:

Flatness:

There is no composite high temperature indentation on the surface. There is no residual stress on the plate surface and no deformation after shearing.

Decorative:

Wood grain, stone grain, realistic material feel, fresh natural beauty. The pattern is free to do, giving customers a wide range of personality choices, enriching the humane content of the product and giving people more enjoyment.

Weather resistance:

Painted and high-temperature baked paint pattern, high gloss retention, good color stability, and minimal color change. The polyester paint is guaranteed for 10 years and the fluorocarbon paint is guaranteed for more than 20 years.

Mechanical:

Made of high-quality aluminum, plastic and adhesive, using advanced composite technology. The product has the bending and bending strength required for the decorative board. Under the four seasons, the changes of wind pressure, temperature, humidity and other factors will not cause bending, deformation and expansion.

Environmental protection:

Resistant to salt and alkali acid rain, it will not corrode and produce germs, and will not release any toxic gases, and will not cause corrosion of keel and fixing parts, and flame retardancy. According to national regulations, it is not lower than B1.

Coated aluminum coil application:

Coated aluminum coils have a wide range of colors, whether it is residential, large commercial outlets or large convention centers, coated aluminum coils add color. Good plasticity and machinability make it an ideal material for a variety of architectural shapes. Coated aluminum coils have provided architects, designers and owners with a personalized color space for exterior walls and ceilings, as well as the ideal material for architectural styling. Whether it is a versatile large building or a unique and innovative new building, the painted aluminum coils can always meet the different requirements of modern and classical architectural styles, and make the building more colorful. Products are used in many fields such as electronics, instruments, lighting, packaging, and home improvement.

The product range is very wide: architectural aspects (aluminum composite panel, aluminum honeycomb, roof wave board, fireproof veneer, aluminum ceiling, blinds, rolling door, garage door, awning, drooping gutter), electronic appliances (computer case, electrical panel) , lighting, furniture, solar reflectors, air conditioning ducts, etc.
