离子交换是一种利用阴阳交换树脂对离子的选择性及平衡反应原理，去除水中电解质离子的技术。系统工作原理是在交换柱内分别填入阴、阳树脂，利用离子交换树脂在水中和钙、镁及钠离子接触交换，从而得到优质纯水及高纯水，水质安全可靠。离子交换树脂是一种高分子化合物，它在水、酸、碱、盐中性能稳定，不溶解,树脂具有交换容量大，耐磨性强，吸附能力高、膨胀小，可长时间使用等特点。

lon-exchange is a lechoogy to remove elecrove in waler by using selecton and balancing fealure ot resin to ions, Coumns are repecively loaded caion resins and anion resinsresins conlact and exchange with Ca Mg and Na ions in water,only left pure water. lon-exchange resins are a high-molecular compound, stable in water or acid, akal and sat soluionInsolublizaion, big exchange and adsorption capacity, well abrasion performance and small explanation, al of these fealures make resins work for a long time.
