As we all know, the plasticity of decorative materials such as metal sandwich boards is very strong, and the decorative effect is comparable to that of aluminum and stone curtain walls. Moreover, the metal sandwich board has a strong self-cleaning ability. Under normal circumstances, residents can clean it as new by washing it with domestic water. The walls that have been used abroad for more than 20 years are still relatively new. However, some users reported that the metal sandwich board has fallen off and asked us whether it is due to quality management problems, but this kind of situation will also occur during the maintenance process of the panels. Here, I will sort out the analysis of the reasons for the shedding of the Chinese metal sandwich board for your reference.
A. Improper handling of the base structure of the wall
1. The components on the outer wall are not firmly fixed and shifted, forming a push-pull effect, which makes the metal sandwich board partially empty, and water seeps for a long time after the crack, causing the metal sandwich board to fall off.
2. Due to the structural deformation of masonry and concrete beams and columns, the metal sandwich board fall off.
B. Improper handling of the wall interface
1. Due to the poor laying of the scaffolding opening, the local base layer of the metal sandwich board insulation layer is not firm and damaged.
C. Improper handling of anti-stress measures
The surface of the metal sandwich board wall material is not treated well with the management interface mortar, which affects the information processing of the metal carved board interface. Different materials fail or the direct economy appears empty. The hollowing of the interface layer and the main wall leads to the hollowing of the insulation layer. In turn, it can lead to the development and separation of Chinese metal sandwich boards. Excessive surface loads such as high-rise buildings or nail-free exterior walls in coastal areas will cause wind pressure damage and hollowing of the metal deck. We need to protect all these things, and the metal sandwich board is no exception. Because it is an exterior wall decoration building material, it is affected by microorganisms in the ambient air all year round, which will accelerate its wear and tear during different periods of use. If you do not pay attention to maintenance, it will lead to shedding.
D. Lack of maintenance measures
If the exterior wall decoration and thermal insulation integrated board fall off during use, users can self-screen through the above reasons, or contact us to learn about the price and knowledge of the metal sandwich board.
