Several main reasons for deformation of hollow aluminum veneer

　　Hollow aluminum veneerWe can see everywhere in our life, this kind of novel wall decoration material can decorate clean and generous, beautiful and elegant wall, and maintenance is particularly convenient. But sometimes the hollowed out aluminum veneer will deform. Today, we will tell you the main reasons for the deformation of the hollow aluminum veneer

　　1.首先， 镂空铝单板没有侧肋和中间肋，在风压和空气上升力作用下发生变形。为了节省成本，一些小型铝板制造商节省了中间肋骨和肋骨，将铝塑板折叠成一个盒子。在车架上螺丝，然后胶合在板间隙，导致空心铝板强度不够，受正负风压对变形的影响。因此，在选择空心铝单板时，应找出大厂家，不要过多地压低价格，否则不择手段的商家会对产品质量进行篡改，以降低成本。

2. Secondly, the hollow aluminum veneer is fixed in the frame of the curtain wall structure, which can not release the thermal stress and cause deformation. Especially in areas with large seasonal temperature difference, aluminum plate and frame will deform due to the influence of temperature.

　　3、第三：面板和边肋产生装配应力变形。为了解决 镂空铝单板的热应力变形问题，铝单板制造商根据开槽机上板的翻边尺寸将凹槽折叠成一个箱体。然后，根据要求的尺寸，切断肋轮廓，组装成带肋框架，并将其加载到箱形嵌板中固定。为了保证时限，通常采用武力组装来维持时限，从而在温度和空气膨胀力的作用下产生气泡。强制装配也常出现在小厂家，技术不成熟，考虑不全面是影响铝单板变形的主要原因。
