What is aluminum honeycomb sandwich panel

MAY. 20, 2020

The center is aluminum hexagonal honeycomb with small density (about 3-7kg / m2), which is 1 / 5 of the weight of wood plate with the same thickness and area, 1 / 6 of glass and 1 / 7 of aluminum material, which greatly reduces the building load and cost. Because the middle interlayer contains a lot of air, aluminum honeycomb sandwich panel can be sound insulated (the air sound insulation can be up to 30dB), heat insulated (the thermal resistance can be up to 0.02 (m.2k / W), There is no combustible substance, the fire rating reaches B1, waterproof, moisture-proof, no toxic gas release, the specific strength per unit mass is large, the specific rigidity is high (the structural rigidity is 1.7 times of rib type). Aluminum honeycomb sandwich panel is not easy to deform, completely overcomes the defects of other decorative boards such as deformation and collapse in the middle when the single block area is large. Aluminum honeycomb sandwich panel is easy to process and installed, it can cut the folded edge arbitrarily, and the fluorocarbon coating on the surface can protect the product life. Its service life is more than 30 years. The surface of aluminum honeycomb plate has a very high flatness and good seismic performance. It is only one eighth of the proportion of glass curtain wall. 22mm thick standard parts are simply supported in 1 meter, and the load can reach more than 700kg when the deflection is 10 mm.


After the surface is treated with fluorocarbon resin with strong corrosion resistance, it can be widely used in the decoration of curtain wall, roof, large-scale door signs and interior wall of the building. The aluminum honeycomb sandwich panel also has excellent weather resistance, and are widely used in building exterior wall decoration due to its light weight, high strength, large stiffness and many other advantages.


The weight of aluminum honeycomb core with the same rigidity is only 1 / 5 of aluminum plate, 1 / 10 of steel plate. The aluminum honeycomb core connected with each other is like countless I-beams. The core layer is distributed and fixed in the whole board surface, which is not easy to produce shear, making the board more stable, more resistant to bending and compression. Its wind pressure resistance is much higher than that of aluminum plastic plate and aluminum veneer, and it has the characteristics of not easy to deform and good flatness. Even if the size of aluminum honeycomb plate is large, it can reach a very high straightness. The honeycomb core in the sandwich panel is divided into many closed chambers, which prevents the air flow and greatly blocks the heat and sound wave. Therefore, aluminum honeycomb sandwich panel has the effect of heat insulation, heat preservation, sound insulation, and the thermal conductivity is 0.104-0.130w/m.k., which is an ideal energy-saving material.
