陶氏反渗透膜LC LE 4040 低压反渗透膜

  陶氏反渗透膜LC LE 4040技术原理是渗透的一种反向迁移运动,它主要是在压力推动下,借助半透膜的截留作用,迫使溶液中的溶剂与溶质分开。溶液浓度越高,渗透压值越大。在反渗透过程中所要施加的压力,在系统和膜强度允许的范围内,必需远大于溶液渗透压值,一般为渗透压值的几倍到近几十倍。当盐的水溶液与多孔的半透膜表面接触时,则在膜的溶液界面上选择吸附一层水分子,在反渗透压力的作用下,通过膜的毛细管作用流出纯水。并连续地流出形成界面纯水层。

  陶氏反渗透膜LC LE 4040分离对象是溶解的离子和分子量几百以上的有机物,能透过溶剂而不能透过溶质的膜一般称之为理想的半透膜。当把溶剂和溶液分别置于此膜的两侧时,纯溶剂将自然穿过半透膜而自发地向溶液一侧流动。这种现象叫渗透。当渗透过程进行到溶液的液面产生一个压力,溶剂向溶液方向流动的趋势,即达到平衡,此压力称为该溶液的渗透压。
