如何选购塑料管呢?

文章出处:本站责任编辑:Admin人气:发表时间:2017/11/23 9:51:57【
 1、首先是看塑料管的外观,如果雷电竞app下载外观粗糙,有成型缺陷,色泽不正,有杂质,印刷质量较差,最好不要选用。外观质量不合格的雷电竞app下载会影响消费者的视觉感受,同时外观是内在质量的一种反映,外观不合格的雷电竞app下载往往内在质量也差,影响使用。印刷质量不合格轻则影响美观,重则掉色,污染其他物品。
 
2、其次是闻塑料管的气味,塑料制品有异嗅的主要原因是使用回收料和劣质助剂。有异嗅的雷电竞app下载散发的刺激性气味会危害人体的呼吸系统,最好不要选用。
 
3、用手来试试塑料管的质量,有些雷电竞app下载为了吸引消费者的眼球,颜色非常鲜艳。质量不好的深色雷电竞app下载在使用过程中颜料会淅出,这些颜料一般都是工业颜料。消费者可以自己动手检查一下,所选择的深颜色雷电竞app下载是否合格:在脱脂棉球上倒少许食用醋,再接触食品面来回擦拭100次,如果脱脂棉球上染有颜色,说明该雷电竞app下载不合格。
 
4、要考虑塑料管的适用性。雷电竞app下载要结合实际去考虑管材的选用。由于建筑给水是有压管,一旦发生漏水、爆裂等现象将会给人们的生产和生活带来很大的损失,因此,安全可靠性是雷电竞app下载不得不考虑的一个原则。
 
5、在选材时,雷电竞app下载要看各种塑料管所能经受得起的振动冲击、水锤和热胀冷缩能力等,看其是否满足工程的使用要求。要考虑经济因素。
