聚丙烯酰胺（PAM）是一種線型高分子聚合物，化學式為(C3H5NO)n。在常溫下為堅硬的玻璃態固體，產品有膠液、膠乳和白色粉粒、半透明珠粒和薄片等。聚丙烯酰胺和其它絮凝劑混合使用添加的順序方法。</p> <div><img src="/d/file/hangye/2021-08-20/938995b9dc69bf111f6b25e64c4c6fa8.jpg" alt="聚丙烯酰胺" width="800" height="600" /></div> <div> 在使用復合絮凝劑的時候必須注意添加的先后順序和投加時間間隔。PAC與PAM聯合使用就是讓PAC先完成中和電荷/膠體脫穩形成細小絮體之后，進一步加大絮體體積有利于充分沉淀。</div> <div> </div> <div> 由于聚合氯化鋁PAC反應時間很短，所以加入后需要強烈的混合，PAM作用時間要長，混合注意先強后弱——先強是為了混合均勻后弱是為了避免破壞絮體。聚丙烯酰胺屬于絮凝劑，聚合氯化鋁屬于混凝劑。</div> <div> </div> <div> 一般情況下是先加混凝劑再加聚丙烯酰胺，但為了保險起見，還是建議大家通過實驗效果來確定添加的順序。加藥點、加藥量、加藥時間以及混合強度需要實驗確定，切記千萬不能把他們兩種藥劑放在一起使用，否則會影響效果，增大使用成本。</div> <div> </div> <div> 以上就是聚丙烯酰胺和其它絮凝劑混合使用添加的順序方法，希望對您有所幫助。聚丙烯酰胺（PAM）是丙烯酰胺均聚物或與其他單體共聚而得聚合物的統稱，是水溶性高分子中應用最廣泛的品種之一。如果您還有其他問題不妨來電咨詢，小編竭誠為您服務。</div> </div> </div> <div style="width:940px; text-align:right; line-height:180%;"
