離子交換樹脂的物理結(jié)構(gòu)是什么　　津達離子交換樹脂較適合用于吸附無機離子，它們的直徑較小，一般為0.3～0.6nm。這類樹脂不能吸附大分子有機物質(zhì)，因后者的尺寸較大，如蛋白質(zhì)分子直徑為5～20nm，不能進入這類樹脂的顯微孔隙中。<br />　　大孔型樹脂是在聚合反應(yīng)時加入致孔劑，形成多孔海綿狀構(gòu)造的骨架，內(nèi)部有大量性的微孔，再導(dǎo)入交換基團制成。它并存有微細(xì)孔和大網(wǎng)孔(macro-pore)，潤濕樹脂的孔徑達100～500nm，其大小和數(shù)量都可以在制造時控制?？椎赖谋砻娣e可以增大到超過1000m2/g。匯珠樹脂公司整理這不僅為離子交換提供了良好的接觸條件，縮短了離子擴散的路程，還增加了許多鏈節(jié)活性中心，通過分子間的范德華引力產(chǎn)生分子吸附作用，能夠象活性炭那樣吸附各種非離子性物質(zhì)，擴大它的功能。一些不帶交換功能團的大孔型樹脂也能夠吸附、分離多種物質(zhì)，例如化工廠廢水中的酚類物。<br />　　大孔樹脂內(nèi)部的孔隙又多又大，表面積很大，活性中心多，離子擴散速度快，離子交換速度也快很多，約比凝膠型樹脂快約十倍。使用時的作用快、效率高，所需處理時間縮短。大孔樹脂還有多種優(yōu)點：耐溶脹，不易碎裂，耐氧化，耐磨損，耐熱及耐溫度變化，以及對有機大分子物質(zhì)較易吸附和交換，因而抗污染力強，并較容易再生。<br />　　凝膠型樹脂的高分子骨架，在干燥的情況下內(nèi)部沒有毛細(xì)孔。它在吸水時潤脹，在大分子鏈節(jié)間形成很微細(xì)的孔隙，通常稱為顯微孔。<br />陰離子交換樹脂預(yù)處理時特別注意的有什么？上一篇：津達鍋爐軟化水樹脂受到污染后反洗步驟是什么？<br /><br />離子交換樹脂的原理？　　離子交換樹脂是由空間網(wǎng)狀結(jié)構(gòu)骨架(即母體)與附屬在骨架上的許多活性基團所構(gòu)成的不溶性高分子化合物。活性基團遇水電離，分成二部分：(1)固定部分，仍與骨架牢固結(jié)合，不能自由移動，構(gòu)成固定離子;(2)活動部分，能在一定空間內(nèi)自由移動，并與其周圍溶液中的其他同性離子進行交換反應(yīng)，稱為可交換離子或反離子。以強酸性陽離子交換樹脂為例，可寫成R-SO3-H+，其中R代表樹脂母體即網(wǎng)狀結(jié)構(gòu)部分，-SO3- 代表活性基團的固定離子，H+為活性基團的可交換離子。有時更簡單地寫成R-H+。離子交換通過不溶性的電解質(zhì)(樹脂)與溶液中的另一種電解質(zhì)進行化學(xué)反應(yīng)。這一反應(yīng)可以是中和反應(yīng)、中性鹽分解或復(fù)分解反應(yīng)。譬如中和反應(yīng)：<br />　　R-H+ + NaOH= RNa+H2O 利用這個反應(yīng)可以去除水的堿度。<br />津達離子交換樹脂是什么？上一篇：離子交換樹脂的性質(zhì)是什么？<br /> </p><br /> <link rel="stylesheet" type="text/css" href="/css/MessageBoard_style.css"> <script language="javascript"
