1、用作水處理助凝劑，陰離子或陽(yáng)離子聚丙烯酰胺通常搭配無(wú)機(jī)絮凝劑聚合氯化鋁等產(chǎn)品被用作凈水助凝劑，可加速絮凝，快速沉淀，達(dá)到污水凈化和除雜的效果。一般是用在沉淀池、氣浮池、芬頓工藝。
2、污泥脫水劑，陽(yáng)離子聚丙烯酰胺可用作污泥脫水劑，主要作用是去除污泥中的水分，降低污泥的含水量，然后通過(guò)帶式壓濾機(jī)、板框壓濾機(jī)、離心壓濾機(jī)、疊螺機(jī)等污泥壓榨設(shè)備進(jìn)行污泥脫水。像建筑泥漿、洗沙行業(yè)也有是用陰離子來(lái)進(jìn)行污泥脫水的，像部分河道清淤的項(xiàng)目也是選用陰離子聚丙烯酰胺的。
3、農(nóng)用土壤疏松劑，保濕劑。灌溉可以防止土壤板結(jié)，改良土壤，防止水土流失。
4、粘著劑，因?yàn)榫郾０返娜芤河幸欢ǖ恼扯龋谝恍┬袠I(yè)可以作為粘合劑使用。嬰兒尿布中的吸水材料等等。
1, used as a water treatment aid coagulant, anionic or cationic polyacrylamide usually with inorganic flocculant polyaluminum chloride and other products are used as water purification aid coagulant, can accelerate flocculation, rapid precipitation, to achieve the effect of sewage purification and impurity removal. Generally used in sedimentation tank, air flotation tank, Fenton process.
2, sludge dehydrating agent, cationic polyacrylamide can be used as sludge dehydrating agent, the main role is to remove the water in the sludge, reduce the water content of the sludge, and then through the belt filter press, plate and frame filter press, centrifugal filter press, pile screw machine and other sludge pressing equipment for sludge dehydration. Like construction mud and sand washing industry, anion is also used to dehydrate sludge, and anionic polyacrylamide is also selected for some river silting projects.
3, agricultural soil loosening agent, humectant. Irrigation can prevent soil compaction, improve the soil, and prevent soil erosion.
4, adhesive, because the polyacrylamide solution has a certain viscosity, it can be used as an adhesive in some industries. Absorbent material in baby diapers and so on.
