Color coated aluminum sheet/coil/strip/foil overview
Color-coated aluminum (रंग-लेपित अॅल्युमिनियम कॉइलमध्ये विभागले जाऊ शकते, रंग-लेपित अॅल्युमिनियम पत्रके, रंग-लेपित अॅल्युमिनियम फॉइल, आणि रंग-लेपित अॅल्युमिनियम पट्ट्या), नावाप्रमाणेच, अॅल्युमिनियम मिश्र धातुंच्या पृष्ठभागाला रंग देणे आहे. सामान्य कलर कोटिंग पद्धतींमध्ये फ्लोरोकार्बन कलर-लेपित अॅल्युमिनियमचा समावेश होतो (रंग-लेपित अॅल्युमिनियम कॉइल), polyester color-coated aluminum (रंग-लेपित अॅल्युमिनियम कॉइल), which are widely used in aluminum-plastic panels, अॅल्युमिनियम लिबास, अॅल्युमिनियम हनीकॉम्ब पॅनेल, अॅल्युमिनियम छत, and roof surfaces. , leftovers, कॅन, इलेक्ट्रॉनिक उत्पादने.
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 विशेष उपचारानंतर वर्षांनी. 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.
