Cosa devi sapere sull'alluminio verniciato a colori?

Color coated aluminum sheet/coil/strip/foil overview

Color-coated aluminum (può essere suddiviso in bobine di alluminio verniciato a colori, lamiere di alluminio verniciate a colori, fogli di alluminio verniciati a colori, e strisce di alluminio verniciate a colori), Come suggerisce il nome, è quello di colorare la superficie delle leghe di alluminio. I metodi comuni di rivestimento colorato includono l'alluminio rivestito di colore con fluorocarburo (bobina in alluminio verniciato a colori), polyester color-coated aluminum (bobina in alluminio verniciato a colori), which are widely used in aluminum-plastic panels, faccette in alluminio, pannelli a nido d'ape in alluminio, soffitti in alluminio, and roof surfaces. , leftovers, lattine, prodotti elettronici.
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 anni dopo un trattamento speciale. 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. 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.
