What is aluminum honeycomb insulated 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, it 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), it 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, it is easy to process and apply, it can cut the folded edge arbitrarily, and the fluorocarbon coating on the surface can protect the product life The 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 front aluminum plate of aluminum honeycomb panel is PVDF fluorocarbon baking paint with composite e.c.c.a. quality standard, which is divided into common color and metal color, so the surface also has excellent weather resistance. Following the innovation of natural products is often to imitate the structure and form of nature. The invention and creation of human beings are all inspired by nature, and adapt to the requirements of nature. Aluminum honeycomb plate has been widely used in building exterior wall decoration due to its light weight, high strength, large stiffness and many other advantages.
The weight of honeycomb sandwich panel with the same rigidity is only 1 / 5 of aluminum plate, 1 / 10 of steel plate, the total thickness is 15mm, the panel is 1.0mm, and the base plate is 0.8mm. The weight is only 6kg / m2. 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 honeycomb composite panel is divided into many closed chambers, which prevents the air flow and greatly blocks the heat and sound wave. Therefore, it has the effect of heat insulation, heat preservation and sound insulation, and the thermal conductivity is 0.104-0.130w/m.k, Therefore, the absorption capacity of aluminum honeycomb plate is 150 ~ 3500kj / M & sup2, which is an ideal energy-saving material.
In case of heavy rain, when raindrops hit the aluminum veneer or aluminum-plastic plate, the noise is particularly loud, while the honeycomb plate avoids this situation. Aluminum honeycomb plate generally uses fluorocarbon roll coating aluminum plate as the panel, and the most important point of fluorocarbon roll coating aluminum plate is that continuous roll coating process is adopted, and the coating of aluminum plate is completed once, so as to ensure that the product has no color difference, good coating flatness and reliable quality, the same as After a long time of sun and rain or industrial waste gas pollution, it is obvious that the roll coating plate is cleaner and brighter than the spray plate, and has good adhesion and weather resistance. It is recognized as the first-class material by the world's builders.
