The center is aluminum hexagon 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 (㎡? K / W)), no combustible materials, and the fire rating can reach B1 It is waterproof, moisture-proof and free of harmful gas release, with high specific strength and specific rigidity per unit mass (structural rigidity is 1.7 times of rib type), and is not easy to deform. It completely overcomes the defects of other decorative boards, such as deformation and middle collapse when the area of a single piece is large, and it is easy to process and apply. It can be cut and folded at will. The surface fluorocarbon coating can guarantee the product life of more than 30 years. The surface of aluminum honeycomb board is extremely With high flatness and good seismic performance, it is only one eighth of the proportion of glass curtain wall; the load of 22mm thick standard parts can reach more than 700kg force when the simple support is 1m and 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 door signs and interior wall of the building. PVDF fluorocarbon baking paint conforming to e.c.c.a. quality standard is adopted for the front aluminum plate of aluminum honeycomb plate, which is divided into common color and metal color. Therefore, the surface also has excellent weather resistance. To follow the innovation of natural products is often to imitate the structure and form of nature. All human inventions and creations are inspired by nature and adapt to the requirements of nature. Aluminum honeycomb panel has been widely used in building exterior wall decoration because of its light weight, high strength, high rigidity and many other advantages. The weight of honeycomb sandwich plate with the same rigidity is only 1 / 5 of aluminum plate and 1 / 10 of steel plate. The total thickness is 15mm, the panel is 1.0mm, and the bottom plate is 0.8mm aluminum honeycomb plate, with a weight of only 6kg / m2. The honeycomb core connected with each other is like countless I-beams. The core layer is distributed and fixed in the whole board, 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 board and aluminum single board, and it is not easy to deform and has good straightness. Even if the honeycomb board is large in size, it can reach a very high straightness because of the honeycomb in the honeycomb composite board The pit core is divided into many closed chambers, which prevents the air flow and greatly blocks the heat and sound waves. Therefore, it has the effect of heat insulation, heat preservation and sound insulation. For 100-3200hz sound source, the long bath can reach 20-30db, and the thermal conductivity is 0.104-0.130w/m.k. therefore, the energy 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 surface of aluminum sheet or aluminum-plastic sheet, the noise is particularly loud, and the honeycomb panel avoids this situation. Aluminum honeycomb plate generally uses fluorocarbon roll coating aluminum plate as panel. The most important point of fluorocarbon roll coating aluminum plate is to adopt continuous roll coating process. The coating of aluminum plate is completed in one time, so as to ensure that the product has no color difference, the coating flow is good and the quality is reliable. At the same time, it can keep the color of the exterior wall of the building bright for a long time. After a long time of exposure to the sun, rain or industrial waste gas pollution, it is obvious that the roll coating plate is cleaner and brighter than the spray coating plate, and has good adhesion and weather resistance. It is recognized as the first-class material by the world's architects.
