摘要
亲和聚丙烯酰胺(英文缩写为PAM),是丙烯酰胺单体(acrylamide,简称AM)及其衍生物在引发剂的作用下的均聚物的统称,是一种线形高分子聚合物,易溶于水,几乎不溶于苯、乙醚、脂类、丙酮等一般有机溶剂。可用做助凝剂、驻留剂、污泥脱水剂以及凝聚沉降剂等,有“百业助剂”之称。它能通过吸附污水中的悬浮的固体粒子,使粒子间架桥或通过电荷中的使粒子凝聚形成大的絮凝物,而得到分离、澄清的效果,进而提高作业效率,降低操作成本。
无色、无味、无嗅,没有腐蚀性。在常温下比较稳定,高温、冰冻时易降解,并降低絮凝效果。故其贮存与配置投加时,温度不得超过65℃,室内温度不得低于2℃。
PAM分为干粉和胶体两种,干粉为白色或灰色粉末,胶体为浅黄色,必须先溶解后才能应用,因此必须制备具有良好溶解性的PAM。
PAM结构可分为阴离子型、阳离子型,两性离子型和非离子型,粉状含固量大于90%.分子量为50万~2300万;胶体含固量(8±)%。

Abstract
Affinity polyacrylamidepolyacrylamide (abbreviation for PAM), acrylamide monomers (Acrylamide, abbreviated as AM) and its derivatives in the initiator's effect of homopolymer collectively, is a linear polymer, easily soluble in water, practically insoluble in benzene, acetone, ether, lipids, and anic solvents. Can be used as a support agent, host agent, sludge dewatering and settlement agent of cohesion, "business promoter," said. It able to by adsorption of suspended solids in wastewater, bridge between particles or by charged particles together to form big ulation, separation, clarification of the effect are, thereby improving operational efficiency and reducing operating costs. A colorless, tasteless, odorless, no corrosion. At room temperature, stable, high temperature, frozen when the degradation and reducing ulating effect. The vote in extra time of their storage and configuration, temperature must not exceed 65 ℃, indoor temperature shall be not less than 2 degrees centigrade.
PAM into powder and gel two, powder white or grey powder, colloids are light yellow, you must first dissolve before it can be applied, so preparation must have a good solubility in PAM.
PAM structure there are anionic, cationic, amphoteric ionic and non-ionic, powdery solid content is greater than 90%. molecular weight of 500,000 ~2300; colloidal solid content (8 ± )%.
Key words:: PAM; application of polyacrylamide; development of polyacrylamide
