</div><div>　　由于運(yùn)輸及保管等各方面的原因，容易使新樹脂產(chǎn)生脫水。憑肉眼和手感均可發(fā)現(xiàn)。如遇此種情況，為避免樹脂與水和其它解析液的接觸而產(chǎn)生產(chǎn)生破碎，造成不必要的浪費(fèi)，必須將此類樹脂浸泡在8%的食鹽水中16小時(shí)左右（浸泡時(shí)需要經(jīng)常攪拌），使樹脂充分膨脹，經(jīng)清水漂洗至無鹽味后方可使用。沒有上述現(xiàn)象，則樹脂不必進(jìn)行預(yù)處理。</div><div> </div><div>　　2、裝填</div><div> </div><div>　　國(guó)內(nèi)混床設(shè)備的樹脂裝填高度為陽樹脂5（6）00mm，陰樹脂10（2）00mm，非解析態(tài)時(shí)（即陽樹脂為鈉型，陰樹脂為氯型時(shí)）陽樹脂裝填高度不能高過中排口，但也不宜低于中排口5cm。陰陽樹脂裝填比例為2：1（或1.5：1）。陽離子交換樹脂在下，陰離子交換樹脂在上。</div><div> </div><div>　　3、沖洗</div><div> </div><div>　　（1）樹脂裝入交換器后，用潔凈水反洗樹脂層，直至出水清晰、無氣味、無細(xì)碎樹脂為止。</div><div> </div><div>　?。?）用約2倍樹脂體積的4-5%HCl溶液，以2m/h的流速通過樹脂層。全部通入后，浸泡4-8小時(shí)，排去酸液，用潔凈水沖洗至出水呈中性，沖洗流速為10-20m/h。</div><div> </div><div>　?。?）用約2倍樹脂體積的2-5%NaOH溶液，按上面進(jìn)HCl溶液的方法通入和浸泡。排去堿液，用潔凈水沖洗至出水呈中性，沖洗流速同上。酸、堿溶液若能重復(fù)進(jìn)行2-3次，則效果更好。</div> <div class="jnvlddtjlh3" id="news_sx"><li id="jnvlddtjlh3"
