With the rapid development of the economy, all kinds of high-end and high-rise buildings are sprouting up all over the place. Green construction materials, such as aluminum wall panels and aluminum honeycomb panels, are commonly employed in high-end structures. There are more and more manufacturers of aluminum cladding and honeycomb panels around the country, but their size is unequal, and the quality of their products cannot be assured. As a result, selecting a high-quality aluminum honeycomb panel is critical. There are three primary characteristics:
The material of the aluminum honeycomb panel face sheet is typically chosen from the 3000 and 5000 series rather than the 1000 series. Spray coating or roller painting is used for surface treatment, and the coating is polyester or fluorocarbon paint. A 3-layer spray coating with a paint layer of 40m would be preferable for the outer wall panel. This ensures the coating's endurance and the color of the honeycomb panel surface will stay for a long time.
Before painting, the aluminum plate is subjected to severe surface anodization to ensure adequate coating adherence and bonding strength with the honeycomb core.
Before painting, the aluminum plate should be rigorously treated by anodizing the surface. This treatment enables adequate coating adherence on the metal plate as well as strong bonding with the honeycomb core.
The face sheet and base sheet should be the same material, with an anodized surface. A protective coating, such as polyester, epoxy, or acrylic, should be applied to the exposed surface. The coating can protect the aluminum sheet against air corrosion over time.
On the aluminum honeycomb core production line, aluminum foil and special honeycomb node glue are used to make the aluminum honeycomb core material. Aluminum foil, node glue, and honeycomb core specifications are among the parameters that influence the performance of the honeycomb core material.
The aluminum foil should be of the 3000 series and have a precise surface treatment. When using 1100 pure aluminum as the honeycomb core material for goods with high strength or durability requirements, extreme caution should be exercised.
Bio-component polymer epoxy adhesive film and bi-component modified epoxy resin are used. It not only has adequate bonding strength, but it also has outstanding environmental resistance as well as high and low-temperature resistance. Due to their poor strength, common adhesives tend to degum the honeycomb core, resulting in overall failure and instability.
The honeycomb core's node strength is the basic basis for measuring its performance, and its node strength data should be 2.0N/mm.
