Color coated aluminum sheet/coil/strip/foil overview
Color-coated aluminum (можна розділити на кольорові алюмінієві котушки, кольорові алюмінієві листи, кольорові алюмінієві фольги, і алюмінієві смуги з кольоровим покриттям), як випливає з назви, полягає в фарбуванні поверхні алюмінієвих сплавів. Загальні методи кольорового покриття включають фторвуглецевий кольоровий алюміній (кольорова алюмінієва котушка), polyester color-coated aluminum (кольорова алюмінієва котушка), which are widely used in aluminum-plastic panels, алюмінієві вініри, алюмінієві стільникові панелі, алюмінієві стелі, and roof surfaces. , leftovers, банки, електронні вироби.
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 років після спеціального лікування. 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.
Four characteristics of color coated aluminum
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. Обробка поверхонь: 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.
