nttntttnttttnttttt如何鉴别铜管的好坏? ntttt | nttt
ntttnttttnttttt ntttttt 紫铜因其颜色为紫红色而得名,比普通钢还重约15%其具有玫瑰红色,外表形成氧化膜后呈紫色,故一般称为紫铜。 nttttt ntttttntttttt 紫铜管的鉴定先要看铜的光彩,紫铜是红色的,越红说明铜含量越高。还有的紫铜管上镀了一锌,有的镀锡,发白色,还有一种劣质铜,铜里面有杂铜里面有杂质,用手一弯就断成两截,里面有黑色杂质,这种铜都是差的。还有鉴定铜是否环保达标,我们就要根据铜的重量来判断了,一般紫铜的密度是8.9如果不是好的紫铜管的话,它的密度肯定达不到,而这是我们判断好差的标准值,所以大家在采购的时候千万要注意。还有在采购紫铜管的时候要注意管面面无划痕,光滑这才是好的紫铜管。 nttttt ntttt | nttt
