检查铝合金门窗的质量,从材质和制作安装两方面着手。 铝合金型材材质质量的好坏与合金成份的配制、熔化、铸造、挤压、表面处理等一系列工序有关,在家庭不具备检验议器设备的情况下,我们用肉眼检查,也可以得出材质质量好坏的结论,主要检查以下几点: 1.查壁厚。常用的70、90系列铝窗型材壁厚为1.2-1.4毫米,铝门型材厚为1.2-2.0毫米,过薄则属薄壁型材,不能 Check the quality of aluminum alloy doors and windows, starting from the material and production installation. The quality of aluminum alloy material is related to a series of processes such as preparation, melting, casting, extrusion, and surface treatment of alloy components. In the case that the family does not have inspection equipment, we can inspect it with the naked eye, and we can also draw The quality of the material is judged to be good or bad. The following points are mainly checked: 1. Check the wall thickness. Commonly used 70, 90 series aluminum window profile thickness is 1.2-1.4 mm, aluminum door profile thickness is 1.2-2.0 mm, too thin is a thin-walled profile, can not
