class="skim"><em>瀏覽次數：</em>523</span><span id="e0oyc0w" class="skimtim"><em>發(fā)布日期：</em>2022-10-25 </span> </div> <div>　　<a href="http://www.nbzmzs.com/Products-33266566.html" target="_blank">混床離子交換樹(shù)脂</a>一般分為陽(yáng)離子樹(shù)脂和陰離子樹(shù)脂兩種，顧名思義，兩種樹(shù)脂分別是用來(lái)吸附(交換)水中陽(yáng)離子如Ca、Mg和陰離子如NO3、SO4等離子。經(jīng)陽(yáng)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(guān)。兩種樹(shù)脂在外形上基本不能區分，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(shù)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(zhì)中的陰離子和陽(yáng)離子之后，水中可能仍存有可溶性的物質(zhì)，會(huì )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(huì )引起細菌的繁殖。在電場(chǎng)的作用下可以實(shí)現水質(zhì)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(guò)水電解產(chǎn)生的氫離子與氫氧根離子對裝填的樹(shù)脂進(jìn)行連續的再生。</div><div> </div><div>　　2、軟化水</div><div> </div><div>　　水質(zhì)中的硬度主要是由其中的陽(yáng)離子，鈣，鎂離子構成。當含有硬度的原水在通過(guò)交換器的樹(shù)脂層時(shí)，水質(zhì)中的鈣，鎂離子會(huì )被樹(shù)脂所吸附，同時(shí)會(huì )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(shù)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(shí)的軟化器會(huì )按照預定的程序自動(dòng)進(jìn)行失效的樹(shù)脂再生工作，利用較高濃度的氯化鈉溶液通過(guò)樹(shù)脂，使失效的樹(shù)脂可以重新恢復到鈉型樹(shù)脂。</div><div> </div><div>　　混床離子交換樹(shù)脂含有大量親水基團，與水接觸即吸水膨脹。當樹(shù)脂中的離子變換時(shí)，如陽(yáng)離子樹(shù)脂由H+轉為Na+，陰樹(shù)脂由Cl-轉為OH-，都因離子直徑增大而發(fā)生膨脹，增大樹(shù)脂的體積。通常，交聯(lián)度低的樹(shù)脂的膨脹度較大。在設計離子交換裝置時(shí)，必須考慮樹(shù)脂的膨脹度，以適應生產(chǎn)運行時(shí)樹(shù)脂中的離子轉換發(fā)生的樹(shù)脂體積變化。</div>
