Aluminum Alloy Curtain Wall Sealing Failure Analysis and Countermeasures-WJW Aluminum Supplier Aluminum

The aluminum alloy curtain wall sealing failure analysis and countermeasure frame and countermeasures and the walls of the wall consist of the enclosure structure and the main structural load are not assumed. It is beautiful, energy saving, convenient maintenance, etc. Implementation and forming building [1]. Aluminum profiles are coating technology. It adds pre -plating and electroplating processes on the basis of conventional titanium plating process. The pre -plating process is to place the active plating parts in the water solution of salt and hydrochloride for chemical treatment for chemical treatment. Home -mounted aluminum materials are coating technology. It adds pre -plating and electroplating process steps on the basis of conventional titanium plating process. The pre -plating process is to place the active plating parts in the water solution of salt and hydrochloride for chemical treatment for chemical treatment. Materials that are connected to the walls and windows doors and windows and doors and windows. The main feature is that the surface of the wall is mostly plane, fixed on the wall, and cannot move. Modern, glass door buildings, stone curtain walls, metal curtain walls, walls and other artificial boards. Metal wall plate aluminum plates, fireproof plates, stainless steel plates, paint steel, etc. The aluminum curtain wall has the following characteristics: 1) rich colors, long -lasting, diverse external shapes, which can be achieved with the perfect combination of glass. The stone wall is sprayed; 2) Light weight, only 1/5 stone walls, glass walls, glass walls One -third, significantly reduces the weight of the exterior wall of the building; 3) The maintenance cost of maintenance is low and cost -effective. Because the aluminum curtain wall has so many advantages, it is widely favored by car owners. At present, the market is mainly used in the market aluminum curtain aluminum aluminum, aluminum -plastic composite board, aluminum honeycomb board. With the use of the aluminum board curtain wall, more and more sealing failure problems occur. The harm caused by the failure of the aluminum -board curtain wall seal is that the curtain wall leaks, which is easy to develop and cause the interior of the building to damage, corrode the curtain wall anchor, affect the safety of the company's building. This article is mainly for the common failure cause of aluminum plate curtain wall seals to differentiates, and it is to conduct research and analysis, and find out the effective teaching method of the enterprise. 2 The reasons for the failure of aluminum board curtain wall seals cause many reasons for the failure of aluminum board curtain wall sealing structure, such as unreasonable design methods, improper selection of sealing, poor bonding, improper construction technology operation management, etc. 2.1 Interface design and sealing gels do not match the aluminum curtain wall interface density sealing often cracks during use, as shown in Figure 1, especially during seasonal changes, the temperature difference between day and night is particularly large, the temperature excessive stretching causes the sealing rubber plate Shrinkage reduction. This is mainly because the drainability of sealing glue cannot meet the actual requirements of actual use. When calculating the width of the seam density seal, in addition to considering the expansion of the plate, the displacement and installation error caused by the dynamic load caused by the floor of the floor should also be considered. The following formula is used to calculate the smaller width required for the interface: the width of the smaller interface = (100/x)*(mtml)锝 Among them, X: the displacement analysis ability of the sealing glue Heat expansion (millimeter) ml: Disposal (MM) TC caused by the effect of dynamic load: Designer of building error (millimeter) designers should choose sealing with reasonable replacement capabilities to avoid cracking due to insufficient sealing capacity replacement capabilities. The replacement capacity of the seal should be based on the report of the national authoritative testing center. In the design, you should also pay attention to the sealing glue formed a double -sided bonding on the interface instead of three sides of bonding. When three sides are bonded, the sealing glue can only withstand 15% of the design capacity. For deeper seams, the polyethylene foam stick should be used to control the thickness of the sealant; for shallow joints, the anti -stick band should be used to open the sealing and the bottom part. Because the use of anti -adhesive tape or polyethylene foam bar can effectively avoid three sides of bonding.
