揭开铝材的真面目

我们在选购铝材的时候经常在观察法来检验它是不是好的产品,其实真的用肉眼是不知道它是真是假的。因为许多铝材门窗都是用铝棒由型材模具挤压制成的,假冒伪劣的铝材都是用废铝做的原材料,所以材质里面含有很多的杂质,挤压的时候比较容易将模具拉毛,这样生产出来的型材表面就没有那么光滑了,我们会看到许多的细纹,而且用废铝生产出来的型材,在强度和硬度上都是不达标的。

假冒伪劣的铝材表面都是做了喷涂修饰,这样处理不仅简单省事,而且还遮盖了铝型材表面的瑕疵。这样的处理方式无疑是生产厂为了节省成本而出的损招。他们大都是用的质量差的粉末来进行喷涂,这些质量差的粉末喷涂效果很差,用不了多少时间就会脱落。而且他们喷涂在型材表面的粉末不是很厚,这些型材通过挤压成型的裂痕大多数都很多,有的裂痕还很深。虽然表面有这层掩饰作用,但是主要我们认真观察,还是能够看到这些破绽。

揭开铝材的真面目

我们在做铝材安装的时候,一定要仔细观察一下型材的表面是否有裂痕。如果你自己看不好的话可以要求技术人员帮你检查一下,看看型材的内壁是否有痕纹。真正的铝材是不会出现任何痕纹的,我们一定要注意在没有喷涂颜色粉末的铝材表面观察才能正确判断真假。还有一种是在材料上区分。真的铝材上都是有的相关标识的。就算是假的铝材它也不会模仿的那么惟妙惟肖,仔细观察肯定会有破绽的。真正的铝材表面色泽比较均匀,不会有波浪状的现象。但是假的铝材都是采用静电喷漆,所以达不到真正铝材表面处理的水平。
