发帖数: 848 | 2 What is PEX?
PEX is cross-linked polyethylene. Through one of several processes, links
between polyethylene molecules are formed to create bridges (thus the term "
cross-linked). This resulting material is more durable under temperature
extremes, chemical attack, and better resists creep deformation, making PEX
an excellent material for hot water and other applications.
How long has PEX been used?
PEX was developed in the 1960s. PEX tubing has been in use in many European
countries for plumbing,... 阅读全帖 |

依云矿泉水都高。但是呢，自然界的矿泉水人类喝了千百年了，没事，循环水还没完全
经受时间考验过。
还有楼主你说坡国水问题全解决了，这绝对不靠谱。PUB官网写得很清楚，和马来第二
份供水协议2061年才到期，还要再进口50年呢，文章里说“高调宣布”，这真是屁话。
wiki上也写着，直到2010年，40%仍靠进口，只有30%不到是循环水，而且循环水中不到
6%用作饮用，而且还是indirect potable use。什么事情还是自己先确认一下比较好
，转载的东西有很多都不可信或不准确。
所以新加坡水处理虽然技术很先进，但依然任重道远。再说要是哪天万一再和马来西亚
合并了，坡国也就不用再搞水循环了，PUB的都该下岗了。 |
