)發(fā)生破碎。因此，樹(shù)脂應有足夠的機械強度，以減少?年樹(shù)脂的損耗量。樹(shù)脂的機械強度取決于交聯(lián)度和溶脹度。交聯(lián)度越大，溶脹度越小，則機械強度越高。</p><p></p><p>離子交換樹(shù)脂</p><p>　　4、化學(xué)穩定性</p><p>　?、倌退釅A性能一般無(wú)機離子交換劑是不耐酸堿的，只能在pH一6～7條件下使用。有機合成強酸、強堿性樹(shù)脂可在pH一1～14中使用。弱酸陽(yáng)樹(shù)脂可在pH≥4時(shí)使用，弱堿陰樹(shù)脂應在pH≤9時(shí)使用。一般樹(shù)脂的抗酸性?xún)?yōu)于抗堿性。無(wú)論是陽(yáng)樹(shù)脂還是陰樹(shù)脂，當在堿的濃度超過(guò)1mol/L時(shí)，都會(huì )發(fā)生分解。</p><p>　?、诳寡趸阅?各種氧化劑如氯、次氯酸、雙氧水、氧、臭氧等會(huì )對樹(shù)脂有不同程度的破壞作用，在使用前需要除去。不同類(lèi)型的樹(shù)脂，受到損壞的程度不同。就其抗氧化的能力來(lái)講，交聯(lián)度高的樹(shù)脂優(yōu)于交聯(lián)度低的樹(shù)脂；聚苯乙烯類(lèi)樹(shù)脂優(yōu)于酚醛類(lèi)樹(shù)脂；鈉型樹(shù)脂優(yōu)于氫型樹(shù)脂;氫型樹(shù)脂優(yōu)于氫氧型樹(shù)脂。大孔樹(shù)脂優(yōu)于凝膠樹(shù)脂。</p><p></p><p>離子交換樹(shù)脂</p><p>　　<span>③</span>樹(shù)脂的交聯(lián)度樹(shù)脂的骨架是靠交聯(lián)劑連接在一起的。交聯(lián)度是指交聯(lián)劑所占有的份數，一般用交聯(lián)劑占單體質(zhì)量百分數來(lái)表示；例如，聚苯乙烯樹(shù)脂用二乙烯苯作交聯(lián)劑，其用量占單體總料量的8時(shí)，則這種樹(shù)脂的交聯(lián)度為8。交聯(lián)度直接影響樹(shù)脂的性能。交聯(lián)度越高，樹(shù)脂的機械強度就越大，對離子的選擇性越強，但離子的交換速率就越慢。這是因為交聯(lián)度高，表明樹(shù)脂的結構緊密，孔隙率低，同時(shí)樹(shù)脂在水中溶脹率也低，因而水中的離子在樹(shù)脂內擴散速度小，影響了離子間的交換能力。</p>
