供应RO膜厂家厂价
2010-07-29 11:51

您好，我对您的产品信息很感兴趣，请给我更详细的产品资料，谢谢！请问您这RO膜是什么成分?渗透机理是什么?
提问者：zmjie2006 时间：2010-06-03 21:39

最早使用于美国太空人将尿液回收为纯水使用。医学界还以反渗透法的技术用来洗肾（血液透析）。反渗透膜可以将重金属、农药、细菌、病毒、杂质等彻底分离。整个工作原理均采用物理法，不添加任何杀菌剂和化学物质，所以不会发生化学变相。并且反渗透膜并不分离溶解氧，所以通过此法生产得出的纯水是活水，喝起来清甜可口。　　反渗透，英文为Reverse Osmosis，它所描绘的是一个自然界中水分自然渗透过程的反向过程。早在1950年美国科学家DR.S.Sourirajan有一回无意中发现海鸥在海上飞行时从海面啜起一大口海水，隔了几秒后吐出一小口的海水。他由此而产生疑问：陆地上由肺呼吸的动物是绝对无法饮用高盐份的海水，那为什么海鸥就可以饮用海水呢？这位科学家把海鸥带回了实验室，经过解剖发现在海鸥囔嗉位置有一层薄膜，该薄膜构造非常精密。海鸥正是利用了这薄膜把海水过滤为可饮用的淡水，而含有杂质及高浓缩盐份的海水则吐出嘴外。这就是以后逆渗透法（Reverse Osmosis 简称 R.O）的基本理论架构。　　对透过的物质具有选择性的薄膜成为半透膜。一般将只能透过溶剂而不能透过溶质的薄膜视为理想的半透膜。当把相同体积的稀溶液（如淡水）和浓液（如海水或盐水）分别置于一容器的两侧，中间用半透膜阻隔，稀溶液中的溶剂将自然的穿过半透膜，向浓溶液侧流动，浓溶液侧的液面会比稀溶液的液面高出一定高度，形成一个压力差，达到渗透平衡状态，此种压力差即为渗透压。渗透压的大小决定于浓液的种类，浓度和温度与半透膜的性质无关。若在浓溶液侧施加一个大于渗透压的压力时，浓溶液中的溶剂会向稀溶液流动，此种溶剂的流动方向与原来渗透的方向相反，这一过程称为反渗透。　　在水处理方面使用反渗透技术在全世界的公认度：　　1、Harvard美国哈佛大学医学院检验合格。　　2、美国国家卫生试验所检验标准。　　National Sanitation Foundation Testing Laboratory Seal 　　3、美国LOMA LINDA大学医学院检验合格。　　4、美国加州ORANGE COUNTY自来水管理局奖赏。　　5、Dr.T.C.McDANIEL美国医学学会推荐。　　6、Wcts检验合格。　　7、CCEL检验超标准。　　8、NASA美国太空总署采用航天飞机装备。　　9、Coca cola（可口可乐）公司采用。　　10、美国海军采用使海水变淡水。　　中国建设部指出：反渗透技术在未来20年内将是最有效、最关键的水处理方式。这就是说纯水机的诞生无疑是饮用水市场发展的必然规律。
