Product Detials
Color coated aluminum coil is a kind of aluminum alloy surface after special coloring treatment of the product, its performance is stable, corrosion resistance, the surface layer can be guaranteed after special treatment at least 30 years without fading. The products are mainly divided into two types: polyester coated aluminum coil (PE) and fluorocarbon coated aluminum coil (PVDF).
Among them, polyester coated aluminum coil is a UV-resistant coating, polyester resin is used in the main chain of polymer containing ester bond as a monomer, adding alkyd resin, UV absorber. According to the gloss level can be further divided into matte and high-gloss series. This type of color coated aluminum coil is especially suitable for interior decoration and advertising panels.
Another type is fluorocarbon coated aluminum coil, which is made of fluorocarbon resin with fluoroalkylene as the basic monomer, pigment, alkyd solvent and additives. After high temperature barbecue film, the molecular structure of the coating is compact, with strong weather resistance. Fluorocarbon coating can be divided into traditional fluorocarbon and nano fluorocarbon coating according to the surface film structure. It is especially suitable for indoor and outdoor decoration of public places, commercial chain, exhibition and advertisement decoration and display.
In addition, color coated aluminum coil is widely welcomed for its bright colors, strong decorative properties, good technical performance, high folding resistance and good aging resistance properties. Different colors can be customized according to the specific needs of business customers, and the application effect is very good.
Product Description
What's more, the color coated aluminum coil has small density, high hardness, the weight per unit volume is the lightest among the metal materials, and never face the plastic steel is always challenged by the word "toxic". Therefore, color coated aluminum coil is widely used in high-grade building doors and windows, sun room, balcony encapsulation and other fields, as well as aluminum ceilings, roof surfaces, scrap steel, cans, aluminum veneer curtain wall and other industries.
Using an aluminum coil as a substrate, at least two layers of coating are added to the top edge. Patterns, colors, and coating types can be customized

Product Inspection
The testing methods of aluminum coil mainly include appearance testing, size deviation testing, mechanical property testing, chemical composition analysis and hardness test and other important items.
Specifically, the appearance test mainly observes whether there are cracks, skinning, bubbles, corrosion, scratches and other defects on the surface of the aluminum coil. While the dimensional deviation detection involves the inspection of length, width, thickness, etc., such as using vernier calipers to measure the cross-section outer dimensions and thickness dimensions of aluminum profiles, and measuring the length dimensions with a tape measure.
Mechanical properties testing is to assess the strength, hardness, toughness and other indicators of aluminum coil, which usually need to be carried out with the help of professional equipment and instruments. Chemical composition analysis is to determine the various elements contained in the aluminum coil and their proportions through laboratory tests, which is also an important basis for judging the quality of aluminum coils.
Finally, the hardness test is used to measure the hardness value of aluminum coils to understand their resistance to compression. In addition, there are special studies on the testing of coil diameter, such as the face roll method, which is used to measure the size of the coil by precisely controlling the position of the face roll.
