What are the structural characteristics of the Aluminum Composite Panel?

  As a Metal Composite Panels Factory, there is some information to share with you. Aluminum composite panel has the characteristics of beautiful appearance, long-lasting, light weight, high strength, strong temperature, good fire resistance, strong acid resistance, good sound insulation, easy maintenance, easy cleaning, etc., and its low cost and good decorative effect Drostanolone Enanthate are very recent The popular new interior and exterior wall decoration materials, together with stone and glass curtain wall, are also called one of the three curtain wall materials, which are attracting attention and love from the people in the construction industry. Very competitive in many decorative panels.

  Aluminum Composite Panel Structural Features

  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 Yichang aluminum profile in the composite board contains toxic components, and the poison gas is used when burning or reaching high temperature, and is used inside and outside. The wall surface is polluted by the environment. At the same time, the aluminum plate and the PVC interlayer are bonded by cementation, and the composite strength is not high. The aluminum plate and the interlayer can be separated by force pulling between the two layers. In addition, since the composite plate is locally heated by the thin aluminum plate, the intermediate interlayer is liable to expand and the aluminum plate 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 self-weight of the board and any external forces received are carried by the four sides of the 0.5mm aluminum plate, and the safety is small.

  Any curtain wall is subjected to different positive and negative wind load pressures at any time. 0.5mm on the four sides of the board is easy to break. This phenomenon has appeared in most projects. Therefore, the Aluminium Composite Panel Wall Cladding must be made with aluminum alloy sub-frames and ribs.
