The center is an aluminum hexagonal honeycomb, the density is small (about 3~7 kg per square meter), it is 1/5 of the weight of the same thickness and area of the board, 1/6 of the glass, 1/7 of the aluminum, greatly reducing the construction load and cost, because the middle sandwich contains a lot of air, it can be soundproofed (air sound insulation up to 30dB), heat insulation (thermal resistance up to 0.02 (㎡· K/W)), no combustible substances, fire grade up to B1, waterproof, moisture-proof, no harmful gas release, large specific strength per unit mass, high specific stiffness (structural stiffness is 1.7 times of rib type), not easy to deform, completely overcome other decorative plates in a single area of large deformation, intermediate collapse and other shortcomings processing and application is convenient, can be arbitrarily cut and folded, the surface fluorocarbon coating can ensure the product life of more than 30 years, the surface of the aluminum honeycomb panel has extremely high flatness, good seismic performance, only one-eighth of the proportion of the glass curtain wall; The load of 22mm thick standard parts can reach more than 700 kg force when the simple support is 1 meter and the deflection is 10mm.
The surface is treated with fluorocarbon resin with strong corrosion resistance, making it widely used in the decoration of curtain walls, roofs, large façade signboards and interior walls of buildings. The front aluminum plate of the aluminum honeycomb panel is made of PVDF fluorocarbon baking paint that meets E. C. C. A. quality standards, and is divided into plain and metallic colors. As a result, the surface also has excellent weather resistance. The innovation of natural products often imitates the structure and form of nature, and human inventions and creations are all inspired by nature and adapted to the requirements of nature. Aluminum honeycomb panels have been widely used in building exterior wall decoration due to their light weight, high strength and high rigidity.
The weight of honeycomb sandwich panels with the same stiffness is only 1/5 of that of aluminum plate and 1/10 of steel plate. The total thickness is 15mm, the panel is 1.0mm, the bottom plate is 0.8mm aluminum honeycomb panel, and the weight is only 6kg/m². Interconnected honeycomb core is like countless I-beams, the core layer is distributed and fixed in the entire board surface, not easy to produce shear, so that the plate is more stable, more resistant to flexure and pressure, its wind pressure resistance greatly exceeds the aluminum-plastic panel and aluminum veneer, and has not easy to deform, good straightness characteristics, even if the honeycomb board size is very large, can also achieve extremely high flatness Because the honeycomb core in the honeycomb composite board is divided into many closed chambers, preventing the flow of air, so that heat and sound waves are greatly hindered, therefore, play a role in heat insulation, heat preservation, sound insulation effect. The sound source of 100-3200HZ can reach 20~30dB, and the thermal conductivity is 0.104-0.130W/M.K, so the energy absorption capacity of aluminum honeycomb panel is 150-3500KJ/M² is an ideal energy-saving material.
In case of heavy rain, the noise is particularly loud when the rain hits the aluminum veneer or aluminum-plastic panel, and the honeycomb board avoids this situation. Aluminum honeycomb panels generally use fluorocarbon roll-coated aluminum plates as panels. The most important point of fluorocarbon roller coated aluminum plate is the continuous roller coating process, the painting of aluminum plate is completed at one time, to ensure that its products have no color difference, good coating leveling, and reliable quality. At the same time, it can keep the color of the exterior wall of the building bright for a long time. After long-term sun and rain or industrial exhaust pollution, it is obvious that the roller coating board is cleaner and brighter than the spray board, and has good adhesion and weather resistance, and is recognized as the first-class material by the world's architects.
