铝单板和铝塑板的区别

9月 9, 2014   //   by yxkj   //   行业新闻  //  0 评论

        铝单板是采用优质铝合金板材为基材,再经过数控折弯等技术成型,表面喷漆装饰性涂料的一种新型幕墙材料。

  铝塑板是以经过化学处理的涂装铝板为表层材料,用聚乙烯塑料为芯材,在专用铝塑板生产设备上加工而成的复合材料。

  产品的外观质量和物理性能:

  项目: 2.5mm铝单板                                                                            4mm厚的铝塑板

  外观质量:平板平整度不高,看上去有局部凹凸               平板平整度比较高,但加工形状受限,可加工成各种不规则形状

  抗拉强度: 130/mm                                                                                38-61N/mm2X

  伸长度: 5%-10%                                                                                       12%-17%

  折弯强度: 84.2N/mm2                                                                        26.136-49.050N/mm2

  从上表可以看出,铝单板的外观比铝塑板差一些,但是其机械性能明显由于铝塑板,其抗风压性能也优于铝塑板。但是在我国大部分地区,其风压值铝塑板是完全可以承受,所以,工程使用铝单板有点大材小用。
