target="_blank">混床離子交換樹脂</a>一般分為陽離子樹脂和陰離子樹脂兩種，顧名思義，兩種樹脂分別是用來吸附(交換)水中陽離子如Ca、Mg和陰離子如NO3、SO4等離子。經(jīng)陽離子處理的水呈堿性，經(jīng)陰離子處理的水呈酸性，與它們吸附離子的不同有關。兩種樹脂在外形上基本不能區(qū)分，均呈黃褐色，比小米粒稍大一些的很輕的顆粒。</div><div> </div><div>　　那么混床離子交換樹脂的主要作用有哪些呢？</div><div> </div><div>　　1、去離子水</div><div> </div><div>　　在去除水質中的陰離子和陽離子之后，水中可能仍存有可溶性的物質，會污染離子交換柱從而使它的功效降低，去離子水在存放之后也會引起細菌的繁殖。在電場的作用下可以實現(xiàn)水質中離子的定向遷移，從而可以達到水的深度凈化除鹽，并且可以通過水電解產(chǎn)生的氫離子與氫氧根離子對裝填的樹脂進行連續(xù)的再生。</div><div> </div><div>　　2、軟化水</div><div> </div><div>　　水質中的硬度主要是由其中的陽離子，鈣，鎂離子構成。當含有硬度的原水在通過交換器的樹脂層時，水質中的鈣，鎂離子會被樹脂所吸附，同時會釋放出鈉離子，這樣交換器內流出的水就達到了去除硬度離子的軟化水的目的。當樹脂吸附鈣，鎂離子達到一定的飽和度之后，出水的硬度增大，此時的軟化器會按照預定的程序自動進行失效的樹脂再生工作，利用較高濃度的氯化鈉溶液通過樹脂，使失效的樹脂可以重新恢復到鈉型樹脂。</div><div> </div><div>　　混床離子交換樹脂含有大量親水基團，與水接觸即吸水膨脹。當樹脂中的離子變換時，如陽離子樹脂由H+轉為Na+，陰樹脂由Cl-轉為OH-，都因離子直徑增大而發(fā)生膨脹，增大樹脂的體積。通常，交聯(lián)度低的樹脂的膨脹度較大。在設計離子交換裝置時，必須考慮樹脂的膨脹度，以適應生產(chǎn)運行時樹脂中的離子轉換發(fā)生的樹脂體積變化。</div> <div
