Color-coated aluminum (színbevonatú alumínium tekercsekre osztható, színes bevonatú alumínium lemezek, színes bevonatú alumínium fóliák, és színes bevonatú alumínium szalagok), ahogy a neve is sugallja, az alumíniumötvözetek felületének színezése. Az elterjedt színes bevonási módszerek közé tartozik a fluor-szénhidrogénnel bevont alumínium (színes bevonatú alumínium tekercs), polyester color-coated aluminum (színes bevonatú alumínium tekercs), which are widely used in aluminum-plastic panels, alumínium furnérok, alumínium méhsejt panelek, alumínium mennyezetek, and roof surfaces. , leftovers, konzervdobozok, elektronikus eszközök. Color-coated aluminum coils are widely used in many fields such as electronic appliances, instruments, lighting, packaging, and home improvement.
The performance of color-coated aluminum is very stable, the surface will not be easily corroded, and the surface layer of color-coated aluminum can be used for 30 évekkel speciális kezelés után. The weight per unit volume of color-coated aluminum is the lighter among metal materials, and it is a new type of metal widely popular at present.
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.
1. Base material standard: According to GB/14978-2008, standard galvanized sheet is used as the base material, the weight of the zinc layer is 40g/m²-180g/㎡ (double-sided), and the surface of the coating layer has good smoothness after laser wool, which is suitable for surfaces such as home appliances occasions with higher requirements; 2. Surface treatment: Passivation treatment is adopted to form a dense corrosion-resistant chemical coating on the surface of the coating, which can increase the adhesion to the coating; 3. Coating system and coating structure: The front adopts two-coating and two-bake coating process. The primer is a matching polyurethane coating with a film thickness of 5-6um; the topcoat is a black or white polyester coating with a film thickness of 12-20um. 4. The surface is covered with a protective film to prevent scratches, and the factory pre-coating process is adopted, eliminating the need for complicated processes such as painting and electrophoresis in downstream factories.
