<h1>陽離子聚丙烯酰胺和陰離子聚丙烯酰胺主要區(qū)別</h1> <div id="vrjfxfb" class="time">點擊次數(shù)：1117 更新時間：2019-05-06</div> <div id="5fftpjx" class="news_wz"><p>陽離子聚丙烯酰胺和陰離子聚丙烯酰胺主要區(qū)別</p><p> 一、外觀上：</p><p> 從外觀上看，幾乎沒有區(qū)別，都是樣是白色顆?；蚍勰畹奈矬w，要區(qū)別它們只能通過小實驗才能分別出來！</p><p> 二、用途區(qū)別：</p><p> 陽離子聚丙烯酰胺（CPAM)是線型高分子化合物，由于它具有多種活潑的基團，可與許多物質(zhì)親和、吸附形成氫鍵。主要是絮凝帶負電荷的膠體，具有除濁、脫色、吸附、粘合等功能，適用于染色、造紙、食品、建筑、冶金、選礦、煤粉、油田、水產(chǎn)加工與發(fā)酵等行業(yè)有機膠體含量較高的廢水處理，特別適用于城市污水、城市污泥、造紙污泥及其它工業(yè)污泥的脫水處理。</p><p> 陽離子聚丙烯酰胺用途：</p><p> 污泥脫水：</p><p> 根據(jù)污性質(zhì)可選用本產(chǎn)品的相應牌號,可有效在污泥進入壓濾之前進行重力污泥脫水。</p><p> 脫水時,產(chǎn)生絮團大,不粘濾布,在壓濾時不流散,用量少,脫水效率高,泥餅含水率在80%以下. 污水和有機廢水的處理:本產(chǎn)品在酸性或堿性介質(zhì)中均呈現(xiàn)陽電性,這樣對污水中懸浮顆粒帶陰電荷的污水進行絮凝沉淀,澄清是極為有效的,如酒精廠廢水,啤酒廠廢水,味精廠廢水,制糖廠廢水,肉食品廠廢水,飲料廠廢水,紡織印染廠的廢水等,用陽離子聚丙烯酰胺要比用陰離子聚丙烯酰胺,非離子聚丙烯酰胺或無機鹽效果要高數(shù)倍或數(shù)十倍,因為這類廢水普遍帶有陰電荷. </p><p> 自來水廠水處理絮凝劑：</p><p> 該產(chǎn)品具有用量少,效果好,成本低等特點,告別是和無機絮凝劑復配使用效果更好.</p><p> 油田化學品：</p><p> 如粘土防膨劑,油田酸化用稠化劑品等. </p><p> 造紙助劑：</p><p> 陽離子PAM紙張增強劑是一種含氨基甲酰基的水溶性陽離子聚合物,具有增強、助留、助濾等功能，可有效地提高紙的強度。同時該產(chǎn)品也是一種分散劑。</p><p> 陰離子聚丙烯酰胺（APAM）是水溶性的高分子聚合物，主要用于各種工業(yè)廢水的絮凝沉降，沉淀澄清處理，如鋼鐵廠廢水，電鍍廠廢水，冶金廢水，洗煤廢水等污水處理、污泥脫水等。還可用于飲用水澄清和凈化處理。由于其分子鏈中含有一定數(shù)量的極性基團，它能通過吸附水中懸浮的固體粒子，使粒子間架橋或通過電荷中和使粒子凝聚形成大的絮凝物，故可加速懸浮液中粒子的沉降，有非常明顯的加快溶液澄清，促進過濾等效果。</p><p> 陰離子聚丙烯酰胺用途：</p><p> 工業(yè)廢水處理：</p><p> 對于懸浮顆粒，較出、濃度高、粒子帶陽電荷，水的PH值為中性或堿性的污水，鋼鐵廠廢水，電鍍廠廢水，冶金廢水，洗煤廢水等污水處理，效果hao</p><p> 飲用水處理：</p><p> 我國很多自來水廠的水源來自江河，泥沙及礦物質(zhì)含量高，比較渾濁，雖經(jīng)過沉淀過濾，仍不能達到要求，需要投加絮凝劑，投加量是無機絮凝劑的1/50，但效果是無機絮凝劑的幾倍，對于有機物污染嚴重的江河水可采用無機絮凝劑和我公司的陽離子聚丙烯酰胺配合使用效果更好。</p><p> 淀粉廠及酒精廠的流失淀粉酒糟的回收：</p><p> 現(xiàn)在很多淀粉廠的廢水內(nèi)含淀粉很多，現(xiàn)投加陰離子聚丙烯酰胺，使淀粉微粒絮凝沉淀，然后將沉淀物經(jīng)壓濾機壓濾變成餅狀，可作飼料，酒精廠的酒精也可采用陰離子聚丙烯酰胺脫水，壓濾進行回收。</p><p> 三、分子量區(qū)別： </p><p> 陽離子聚丙烯酰胺的分子量一般為500萬至1200萬。</p><p> 陰離子聚丙烯酰胺的分子量一般為800萬-2000。！</p></div> <div id="53lrrlt" class="ye">上一篇：<a href="/Article-543144.html">在石油工業(yè)中聚丙烯酰胺污泥脫水的應用</a> 下一篇：<a href="/Article-539297.html">土壤改良劑聚丙烯酰胺在土壤中的重要作用</a></div> </div>
