Surface Treatment Technology of Aluminum Corrugated Composite Board

The aluminum corrugated board is continuously bent and formed by an aluminum plate bending machine, and then a decorative coating composite substrate is sprayed on its surface

Aluminum corrugated board is coated with adhesive. Corrugated core is a new type of high quality composite material, which is bonded and compounded by aluminum plate.

产品结构：铝瓦楞复合板是三层夹心复合材料，由表面两层铝板和背面两层铝板瓦楞芯粘合而成，这不仅获得了产品优异的性能，而且大大减少了材料的用量。铝瓦楞板背面通常是对称的。可以使用同一品牌和厚度的铝合金瓦楞板。但是，如果背板厚度小于面板厚度，通常不小于面板厚度的一半，也可以使用不对称结构。瓦楞复合板采用al3003h16-h18材料制成，面板厚度为0.8~1.0mm，背板厚度为0.4~0.5mm（与铝蜂窝板相同），芯板为al100h16-h18，材料厚度为0.2mm（蜂窝板芯板为0.06~0.07mm），为水波纹型，与面板背板的粘接面为圆弧型，使用热固性树脂粘合剂，提高粘接强度（高于蜂窝板），与金属板的附着力极佳，采用最先进的ERP系统质量管理体系，在先进的全自动生产设备上生产，保证粘接性能稳定、牢固、耐用，使用寿命.
aluminum corrugated composite board performance:
1 Stable bonding performance, strong and durable:
The aluminum corrugated composite board is made of al3003h16-h18 material, the thickness of the panel is 0.8~1.0mm, the thickness of the back plate is 0.4~0.5mm (the same as the aluminum honeycomb panel), the core plate is made of al100h16-h18, the thickness of the material is 0.2mm (the thickness of the honeycomb core plate is 0.06~0.07mm), it is water corrugated type, the joint surface with the panel back plate is arc-shaped, and the joint strength is improved (higher than the honeycomb plate). The thermosetting resin adhesive has excellent adhesion to a metal plate. Using the most advanced ERP system quality management system, in the advanced automatic production equipment production, to ensure stable bonding performance, firm and durable.

II; same service life. Energy conservation and environmental protection:
The core plate of the corrugated composite board is water-corrugated, forming an air duct between the panel and the back plate. It is a hollow board system and the best product for heat insulation. Under the action of solar radiation, the air in the channel heats up and flows upward to take away heat, which has heat insulation performance
 
In cold areas, the upper and lower ends of the corrugated channel are sealed, and heat energy is stored in the sun during the day to reduce the loss of indoor heating heat and has heat preservation performance.
 
3. Sound insulation and noise reduction:
Because the core plate is corrugated arc type, it reflects the sound waves, eliminates the acoustic coupling between the panel and the back plate, and improves the sound insulation performance by more than 35dB.
 
4. Ultra-high flatness:
Aluminum corrugated composite plate is 2.35x 10-5 because the thickness of aluminum plate is 0.5mm, the bearing capacity after folding is small, and the linear expansion coefficient of aluminum veneer is large, which is not suitable for large plates or high curtain wall projects. The cold shrinkage and thermal expansion deformation of aluminum veneer are large. In general, aluminum veneer use 1-2 years after the surface will appear concave and convex deformation, affecting the artistry of the building facade. Honeycomb board surface flatness is good, but the price is high, so it is not suitable for engineering. The tensile strength, compressive strength and 180 degree peel strength (see the test report) of aluminum corrugated cardboard are higher than those of honeycomb cardboard, so it has ultra-high surface flatness, stability and durability.

5. Fluorocarbon Coating:
The corrugated board panel is fluorocarbon roll coating. Due to the automatic assembly line production line for degreasing, degreasing, cleaning, drying and chromic treatment on the surface of aluminum plate, it is ensured that the coating thickness is uniform, the adhesion is good, the color is different, and the anti-stone material is provided. The effect of this pattern is available. 

 6、重量轻、经济：
Corrugated cardboard is 6mm thick and has a specific gravity of 4.3kg/m2. It is more economical because the heavy load of the surface material is small and the structural support keel can be reduced.
 
7. Easy to clean, corrosion resistance, strong anti-fouling ability, good durability and no discoloration
 
8, large specifications, improve the utilization rate of materials:
The width of the corrugated composite board is 1000~1550mm, the length is 300~6000mm, and the thickness is 4~8mm. Reasonable selection of various curtain walls to improve material utilization and reduce costs
 
9, easy processing and installation
Easy processing: It can be cut, perforated, bent, and can be made into special-shaped flat plates and arc plates. The side ribs and the reinforced middle auxiliary parts can be connected by rivets, which is simple and firm.
 
Convenient installation and construction: fixed distance crimping, hanging, opening and closing structure can be used to ensure smooth surface, safety and durability, and more architectural art. See node diagram for details
 
10. Value ratio:
Aluminum corrugated cardboard has the above-mentioned ultra-high performance, and the price is close to 3mm thick aluminum veneer, which is economical.
