The decorative panels for aluminum honeycomb panels typically use grades such as 3003, 5005, etc., while 1100 aluminum plates with low alloy content are less commonly used. The decorative surface is coated by spraying or rolling, with polyester or fluorocarbon paint as the coating. For exterior panels, it's better to choose spray-coated panels, and they should have three coatings or more, with a paint film thickness of ≥40μm to ensure the durability of the coating.
The back panel of aluminum honeycomb panels should be made of the same material as the panel surface, which should be anodized and coated with a protective layer on the side exposed to the air. The coating material can be polyester, epoxy, acrylic, etc., to prevent rusting of the aluminum plate due to long-term exposure to the air.
Aluminum honeycomb panels weigh only 1/5 of aluminum sheets and 1/10 of steel sheets with the same rigidity. A panel with a total thickness of 15mm, a face panel of 1.0mm, and a bottom panel of 0.8mm weighs just 6 kg/sq. m. The interconnected honeycomb cores act like numerous I-beams, distributed and fixed throughout the entire panel surface, making it less prone to shearing and enhancing stability, bending resistance, and compressive strength. Their wind pressure resistance exceeds that of aluminum-plastic panels and aluminum single panels, and they are known for their non-deformability and good flatness. Even with large honeycomb panel sizes, they can achieve exceptional flatness. The honeycomb cores within the composite panels are divided into numerous sealed small cells, blocking air flow and significantly hindering heat and sound waves, thus providing excellent thermal insulation, heat preservation, and soundproofing. They can reduce noise from 100 - 3200 Hz by 20~30 dB, with a thermal conductivity of 0.104-0.130 W/M.K, making aluminum honeycomb panels capable of absorbing 150-3500 KJ/M² of energy, an ideal energy-saving material.
Aluminum honeycomb panels, after being treated with highly corrosion-resistant fluorocarbon resin, are widely used for the cladding, roofing, large signage, and interior decoration of buildings. The front aluminum sheet of the panels is coated with PVDF fluorocarbon paint that meets the E. C. C. A. quality standard, available in both standard and metallic colors. Consequently, the surface also boasts excellent weather resistance. Innovation that follows the natural world often imitates the structures and forms of nature, as human invention and creation are constantly inspired by and adapted to the demands of nature. With its many advantages such as light weight, high strength, and large rigidity, aluminum honeycomb panels have been extensively applied in the exterior decoration of buildings.
