Aluminum Composite Panel Tips

Let us first talk about the material composition of the Aluminum Composite Panel, which plays a direct and decisive role in its use. It can be seen literally that it is a combination of aluminum and plastic. The characteristics of the composite board are that they combine the advantages of the two materials and overcome their own shortcomings. The two materials of aluminum and plastic are widely used, and the combination of the two makes the composite board have unique performance. The scope of use is even wider. The performance of aluminum-plastic composite board is mainly reflected in its fire and impact resistance. It is rich in color and will not damage its appearance during the changing seasons. Therefore, it is very suitable for the decoration of exterior walls and can replace the old materials. Used in the renovation of old walls, its texture is relatively light, easy to carry, and processing is very convenient, which can save a lot of manpower and material resources. In addition, it can also be used on the interior wall decoration, can be used as a sign board, display stand, etc., is a good building decoration material.

　　The aluminum composite panel consists of a 0.5 mm thick aluminum plate sandwiched between the inner and outer layers. The 2-5 mm thick aluminum plate has a thin roll of carbon fluoride sprayed topcoat. The composite board is characterized by uniform color and smooth surface, and is convenient to manufacture. However, the composite board has the disadvantage that the interlayer of the composite board contains toxic components, and when the combustion or high temperature is used, the poison gas is used, and the inner and outer walls are used. The environment is polluted, and the aluminum plate and the PVC interlayer are bonded by cementation, and the composite strength is not high, and the aluminum plate and the interlayer can be separated by pulling together between the two layers.

In addition, because Aluminium Composite Panel Sheets for Construction is very thin and locally heated, the middle interlayer is prone to expansion and the aluminum sheet is bulged outward. From the perspective of curtain wall lightning protection, the aluminum composite panel is formed by two layers of 0.5 mm thick aluminum sheets bonded to polyethylene. Polyethylene is a poor conductor, two layers of aluminum sheet are in an insulated state. Although the inner layer is made of aluminum alloy sub-frame when the composite aluminum sheet is made, the rivet and the aluminum composite board are fixedly bent on four sides; since the riveting surface is too small, more importantly The 0.5mm aluminum sheet is too thin. When lightning strikes, the large flash current will break through the 0.5mm aluminum sheet when the building is laterally developed to circumvent the curtain wall panel. The strong current is difficult to strike the building through the grounding of the composite board.

　　From the production and installation of the aluminum composite panel: the production of the aluminum composite panel is first slotted on the four sides of the composite panel, and the outer aluminum panel with a certain width and an aluminum plate and a plastic layer leaving only 0.5 mm thick is cut, and the four sides are bent at a 90° angle to form a rectangle. Then, the rectangular sub-frame of the same size is made of aluminum material and placed in the rectangular groove of the aluminum-plastic plate. The bottom surface of the sub-frame is glued with the back surface of the aluminum-plastic plate, and the four sides of the composite plate are fixed on the four sides of the sub-frame by the riveting, in the middle of the rectangle. Then use a structure to glue one to several aluminum profile ribs. At present, most of the installation and production units are not made according to the above method, and the upper side of the aluminum composite plate is bent at a 90° angle, and only the four folded edges of the composite plate are fixed by the angle aluminum. In this way, the surface of the panel is self-reinforcing, and the aluminum profiles of the doors and windows and any external forces are subjected to any load of four 0.5mm aluminum plates, which is safe. Any curtain wall is subject to different positive and negative wind load pressures at any time. 0.5mm on the four sides of the board is easy to break a large number of Aluminum Composite Panel Supplier direct sales. This phenomenon has appeared in most projects, so the aluminum-plastic composite panel curtain wall must be added with aluminum alloy Frame and ribs.
