Since its birth, the aluminum wall sheets for curtain wall has been favored by designers for its unique texture, rich color, excellent plasticity, form diversity and weather resistance. In its usage by people more and more popular in modern buildings, is a leap of building decoration, the installation of exterior decorative panels in the form of aluminum curtain walls can be used in high-rise buildings of any building, any height, any part, and any structural form, thus breaking the inability of high-rise buildings and super high-rise buildings. Aluminum curtain wall has become the symbol of modern architecture. However, with the increasing shortage of global resources and energy and the need for product and technology updates and upgrades for aluminum curtain walls.
As far as the current aluminum wall sheets for curtain wall is concerned, aluminum curtain wall sheet and composite aluminum plastic panel are still the main product choices. The honeycomb composite aluminum panel that has appeared in recent years is only used in some special projects due to its low plasticity in lateral bending. Curtain wall aluminum plate is still the leading product of aluminum curtain wall due to its strong plasticity, strong wind resistance and all-weather performance, but due to the process of aluminum veneer cutting, bending, back rib welding, surface spraying and coloring during processing. During the whole process of transportation and installation, the flatness, smoothness and color difference cannot be effectively controlled, resulting in the utilization rate, flatness, color difference, etc., which often lead to disputes over project quality.
The composite aluminum composite panel has the same plasticity as the aluminum wall sheet. Its advantages are light weight, good surface smoothness, no color difference when installed in the same direction, and excellent on-site processability. Reduce the processing cycle and shorten the installation period to create conditions. The fluorocarbon coating on the surface of the composite aluminum-plastic panel is also completed by online roller coating, rolling and heat sealing at one time. However, in the production process of aluminum composite panels, the expansion coefficients of aluminum wall sheets and plastics are quite different, and blistering and peeling are prone to occur.
