                                    饮用水管的常用材料有哪些?   家装常用水管大致可分为镀锌管、UPVC管,铝塑管、PPR管、铜管和不绣钢管几类。   镀锌管:老房子大部分用的都是镀锌管,现在煤气、暖气用的那种铁管也是镀锌管,镀...

                                      镀锌管:老房子大部分用的都是镀锌管,现在煤气、暖气用的那种铁管也是镀锌管,镀锌管作为水管,使用几年后,管内产生大量锈垢,流出的黄水不仅污染洁具,而且夹杂着不光滑内壁滋生的细菌,锈蚀造成水中重金属含量过高,严重危害人体的健康。六七十年代,国际上发达国家开始开发新型管材,并陆续禁用镀锌管。中国建设部等四部委也发文明确从二000年起禁用镀锌管,目前新建小区的冷水管已经很少使用镀锌管了,有些小区的热水管使用的是镀锌管。
                                      UPVC管:实际上就是一种塑料管,接口处一般用胶粘接,UPVC管的抗冻和耐热能力都不好,所以很难用作热水管,由于其强度不能适用于水管的承压要求,所以冷水管也很少使用。大部分情况下,PVC管适用于电线管道和排污管道。另外,近年内科技界发现,能使PVC变得更为柔软的化学添加剂酞,对人体内肾、肝、睾丸影响甚大,会导致癌症、肾损坏,破坏人体功能再造系统,影响发育。所以建议大家不要购买。

                                      不锈钢管:属于非常贵的水管,施工困难,很少被采用,性能与铜管类似。 我是这么看待水管问题的,房子装修,水管最好一次到位,墙、地坏了,可以很容意补,但是水管有问题,一是已经被埋在了墙里,很难修复,二是如果遇到主人不在家,水管漏水,恐怕带来的不光是你自己的经济损失和麻烦,更可能带来楼下住户的损失和麻烦,所以,你可以先在龙头、五金的地方省些钱,但是在水管问题上,一定不能省。
