絮凝劑上料泵主(zhu)要是帶有正(zheng)（負(fu))電(dian)性(xing)的(de)(de)基(ji)團(tuan)(tuan)和水中(zhong)(zhong)(zhong)(zhong)帶有負(fu)(正(zheng)）電(dian)性(xing)的(de)(de)難于分離的(de)(de)一些粒(li)(li)子(zi)或者顆(ke)粒(li)(li)相(xiang)互靠(kao)近，降低其電(dian)勢，使其處于不(bu)穩定狀(zhuang)態，并利用(yong)(yong)其聚(ju)合性(xing)質使得(de)這些顆(ke)粒(li)(li)集中(zhong)(zhong)(zhong)(zhong)，并通(tong)(tong)過(guo)物理或者化學(xue)方法分離出來。絮(xu)凝(ning)(ning)：將溶(rong)(rong)液中(zhong)(zhong)(zhong)(zhong)不(bu)需要的(de)(de)成(cheng)分通(tong)(tong)過(guo)絮(xu)狀(zhuang)凝(ning)(ning)集方式去(qu)除的(de)(de)過(guo)程(cheng)(cheng)。在(zai)此(ci)過(guo)程(cheng)(cheng)中(zhong)(zhong)(zhong)(zhong)用(yong)(yong)到的(de)(de)助(zhu)劑(ji)稱為絮(xu)凝(ning)(ning)劑(ji)。絮(xu)凝(ning)(ning)劑(ji)品種較多，共同特點(dian)是能(neng)夠將溶(rong)(rong)液中(zhong)(zhong)(zhong)(zhong)的(de)(de)懸浮微粒(li)(li)聚(ju)集聯結形(xing)成(cheng)粗(cu)大的(de)(de)絮(xu)狀(zhuang)團(tuan)(tuan)粒(li)(li)或團(tuan)(tuan)塊(kuai)。
