Product Overview:
Aluminum corrugated core composite aluminum plate, also known as aluminum corrugated composite plate, is composed of fluorocarbon roller coated panel, corrugated core double-sided roller coated two-component epoxy resin adhesive, and surface treated backing plate. In the fully automated production line, the cold pressed water ripple type is used, and the bonding surface between the thermosetting two-component structural resin adhesive and the panel backboard is arc-shaped, which increases the excellent bonding force of the metal plate and ensures stable and firm bonding performance, as well as durability of the same life as the building.
Product Structure:
Aluminum corrugated core composite aluminum plate is a sandwich and hollow new type of metal composite material made by bonding a specially modified thermosetting epoxy resin adhesive to a coated surface bottom aluminum plate and a corrugated core aluminum plate that have undergone physical oxidation surface pretreatment;
Both the panel and the bottom plate are made of high-quality high-strength aluminum alloy AA3003H16-H18 sheet, with commonly used thicknesses of 4.0 and 6.0mm. The conventional material dimensions can have a width of 800-1590mm and a maximum length of 8000mm to 10000mm.
The thickness of aluminum material and the wall thickness of aluminum corrugated core shall not be less than the nominal value. The deviation of aluminum material thickness shall comply with the provisions of GB/T 3880.3, and the deviation of aluminum corrugated core wall thickness shall comply with the provisions of GB/T 3198. The nominal thickness of the panel of the aluminum corrugated core composite aluminum plate is not less than 0.8mm, the nominal thickness of the back plate is not less than 0.4mm, and the wall thickness of the aluminum corrugated core is not less than 0.20mm. The front of the decorative surface layer is treated with fluorocarbon roller coating (second coating), with an average film thickness of not less than 25 μ m and a minimum local film thickness of not less than 23 μ m. The average film thickness of polyester and acrylic is>16 μ m, and the minimum local film thickness is>14 μ m. The fluorocarbon coating should provide a 15 year quality guarantee, and the combustion performance level of the entire board is A2 level.
Product Features:
● Superior flatness
The board surface is flat and beautiful, with a stable structure, suitable for use with large board widths, and visually smooth and flat.
● Excellent durability
The bonding performance of aluminum corrugated core composite aluminum plate is stable, firm and durable. Due to its tensile and compressive strength, the 180 degree peel strength is higher than that of honeycomb board, so it has a super high surface flatness and is easy to process. It shortens the construction time and saves costs during construction. Due to its light weight, it reduces the disclosure load of buildings and can extend the service life of buildings. Its stability and durability are the same as those of buildings. Rich in color, easy to clean and maintain, corrosion-resistant, strong anti fouling ability, and durable without discoloration.
● Simple processability
Easy to process and install, capable of cutting, punching, bending, and can be made into irregular flat or curved plates. The edge ribs and reinforcement can be connected with rivets, which is simple, firm and more artistic in architecture.
● Lightweight nature
The unit weight of aluminum corrugated core composite aluminum plate is 5kg/m2, which shortens the construction time during construction and has strong effectiveness. Reducing the disclosure load of buildings due to their lightweight can prolong their lifespan.
● Processing capability
Light weight, due to the weight of the surface material and the small load, while the structural support keel can be reduced, it is more economical. The maximum size of the board is a large flat plate, which improves the utilization rate of materials and reduces costs.
● Decorative
Aluminum corrugated core composite aluminum plate perfectly combines function and aesthetics, utilizing the advantages of metal aluminum honeycomb panels to solve the shortcomings of aluminum veneer and aluminum-plastic panels, making the building more beautiful and greatly enhancing the decorative appearance of the building.
● Green environmental friendliness
Aluminum corrugated core composite aluminum plate is easy to clean, easy to maintain, non-toxic, and free of harmful gas release, meeting the requirements of green environmental protection.
● Soundproofing performance
Sound insulation and noise reduction, due to the corrugated arc shape of the core board, generate curved reflections of sound waves, eliminate the coupling of sound waves between the panel and the back board, reduce 26dB of noise, and have a good attenuation effect on low-frequency sound noise.
● Thermal insulation
The core plate of aluminum corrugated core composite aluminum plate is of water ripple type, which forms an air channel between the panel and the back plate, making it the best product for thermal insulation. Under the direct sunlight, the air in the channel heats up and flows upwards to carry away heat, possessing insulation properties.
● A-level fire resistance
Metal aluminum corrugated core composite board is a fully metal bending structure. In the event of a major fire, the combustion products do not contain toxic gases such as ammonia, sulfide halogens, heavy metals, etc. The fire rating is A, which can meet the fire protection requirements of high-rise buildings.
Product processing:
● Cutting
The aluminum corrugated core composite aluminum plate is cut using a dedicated cutting machine, which is fixed on a flat surface or an equivalent or higher workbench without moving, and then cut to the desired production size. After cutting, the cross-section should form a very soft and clean cutting surface.
● Grooving
The very important process in the processing of aluminum corrugated core composite aluminum plate is to scrape off the back of the panel by 0.2mm, and the recommended processing angle is to process the bottom plate and core material together into a 91 ° angle
Corner.
1) The processing saw teeth are made of R-5.5 with an angle of 91 °, similar to the lower central drawing.
2) When a large number of grooves are used in engineering, the use of CNC slotting equipment can better improve production efficiency.
Slotting: According to the requirements of the design drawings, the processing method for folding can be cut according to the left figure.
● Forming
After groove machining, the product is positioned on a certain plane, and the bending fixture is bent at a 90 ° angle to meet the requirements of the design drawing.
● Rolling and bending
Use the corresponding roller rounding equipment to round it up.
● Precautions for slotting processing
Double bending and inconsistent cross-section:
-When slotting, the outer panel was machined to a depth of 0.2mm.
-The bending fixture is not inserted into the flange enough. It is recommended to insert the fixture into the flange to the maximum extent possible for bending.
-The proficiency of the operator is required when slotting, and it is recommended to use professional technicians.
-Due to uneven pressure of the slotting equipment, the processing depth is poor and the bending part is uneven. It is hoped that the mechanical processing pressure can be kept stable.
