Advanced Color-Coated Process

Polyester-coated pre-coating Technology(PE Coating)

The polyester coating is a kind of anti-UV UV polyester resin coating; its main component uses polymers containing ester bonds in the main chain as monomers, adding alkyd resin and an ultraviolet absorber. After baking polyester coating on the surface of aluminum (aluminum sheet, aluminum roll) many times, it forms a solid film with protection and decoration. The polyester coating protects color-coated aluminum products (aluminum sheets, aluminum rolls) from exposure to the atmosphere due to temperature differences, freeze-thaw cycles, corrosive gases and microorganisms, ultraviolet radiation, wind, rain, frost, and snow.

In addition, the polyester coating can give color-coated aluminum substrate products rich color. According to gloss, the polyester coating can be divided into matte and highlight series. Therefore, the color-coated aluminum coil not only has good gloss and smoothness but also superior texture and feel and can also increase the sense of layer and three-dimensionality. It is especially suitable for interior decoration and advertising boards.

polyvinylidene difluoride coating technology(PVDF Coating)

Fluorocarbon coating is PVDF resin. It mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride and other small amounts of fluorinated vinyl monomer copolymer coatings. The fluoric acid-base material with a fluorine/carbonization bond has a stable and firm chemical structure, which makes the physical properties of fluorocarbon coatings different from those of general coatings.

Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the film formation structure of the surface. In 1965, the Pennwalt Chemical Company of the United States, for the first time, used fluorocarbon paint for the coating of indoor and outdoor aluminum in high-grade buildings, a wide range of color selectivity, solemn appearance, and durability for many magnificent curtain wall buildings around the world added luster. In addition to the wear and impact resistance in terms of mechanical properties, it also shows excellent and long-term fading resistance and UV resistance in harsh climates and humid environments. After high-temperature grilling, the molecular structure of the coating is tight, and the machine has superior weather resistance. The coating manufacturer’s guarantee of the service life of the coating began to be 10 years, 15 years to guarantee more than 20 years.

American research institutions have tested and compared fluorocarbon, super, and general coatings. The samples of the coatings were exposed to hot sunlight in Florida, the United States, and exposed to the harsh environment of humid salty air for 12 years, which proves that the stability and durability of fluorocarbon coatings are 30%-80% higher than those of the other two coatings. Fluorocarbon coatings ensure that they can be used in various harsh environments. It is especially suitable for indoor and outdoor decoration in public places, commercial chains, exhibition advertising, and other decorations and displays.

1100 Corrosion resistance

1100 aluminum coil chemical properties are very active. At 20℃, its standard potential is -1.69V, which makes it easy to form a firm and tight oxide film by the action of oxygen in the air, and the standard point is raised to -0.5V. So, aluminum is resistant to corrosion in the atmosphere. However, with the increase of impurities, the continuity of the oxide film is destroyed to form a micro battery, reducing its corrosion resistance.

The corrosion resistance of the 1100 aluminum coil in pure water mainly depends on the water temperature, water quality, and aluminum purity. When the water temperature is lower than 50℃, with the improvement of water quality and aluminum purity, the corrosion resistance of the 1100 aluminum coil is improved, and the corrosion appearance is mainly spot-like. If the water contains a small quantity of active ions (Cl-, Cu+, etc.), the corrosion resistance of aluminum is sharply reduced.

The corrosion resistance of 1100 aluminum coil in acid and alkali is roughly as follows

Factors Affecting the Weight of Aluminum Rolls

The weight of an aluminum coil depends on its material density, length, width, and thickness. The same specification of aluminum coil, different manufacturers may produce a certain difference in weight, which can be measured by a weight meter and other equipment. At the same time, the coating material and treatment process in the production process of the aluminum coil will also have a certain impact on the weight of the aluminum coil. Generally, the weight of the common aluminum coil is between 500 and 5000kg.

Aluminum coil weight calculation formula

Aluminum coil weight (kg) = aluminum coil length (m) × aluminum coil width (m) × aluminum coil thickness (m) × aluminum coil density (kg/m³)

Among them, the density of the aluminum coil is 2.7×103kg/m³.

For example, if the aluminum coil’s specifications are a width of 1 m, a thickness of 0.3 mm, and a length of 100 m, then the weight can be calculated according to the following formula: weight = 2.7 g/cm3 x 10,000cm x 100 cmx0.03 cm = 81,000 g = 81Kg.

Notes: When calculating the weight of the aluminum coil, it is necessary to pay attention to the unity of the unit, such as the length and width need to be converted into centimeters or meters.

Weight reference value corresponding to common specifications of aluminum coil

The following are common aluminum coil weight reference values for reference only:

  • The weight of the 1.0mm thickness aluminum coil specification is about 2.7kg/m², and 1 ton of aluminum coil can be divided into about 370 sheets, with a width of 1.25 meters and a length of 10 meters each.
  • The weight of the 0.6mm thickness aluminum coil specification is about 1.5kg/m², and 1 ton of aluminum coil can be divided into about 667 sheets, with a width of 1.25 meters and a length of 10 meters each.

The above data is for reference only. The specific weight must be calculated and measured according to the aluminum coil’s specifications.

When calculating the length of the aluminum coil, it is necessary to understand the specific specifications. Generally speaking, the specifications will indicate the aluminum coil’s width, thickness, and length. If only partial information about the weight and specifications of the aluminum coil is known, the length of the aluminum coil can be reversed.

For example, if the aluminum coil specification is 800mm wide, 0.5mm thick, 100kg in weight, and the density of aluminum is known to be 2.7g/cm³, then its length can be calculated as follows:

  • Step1: Calculate the aluminum coil area

Area = 800mm x 0.5mm = 400mm² = 0.04m²

  • Step2: Calculate the aluminum coil length

Length = 100kg / 2.7g/cm³ / 0.04m² = 925.93m

Therefore, the length of the above aluminum coil is 925.93m.

Notes: When calculating the length of the aluminum coil, please pay attention to the distinction between standard specifications and the correct application of the weight calculation formula.
