非离子型聚丙烯酰胺絮凝剂的制备及其絮凝性能
Preparation of Nonionic Polyacrylamide Flocculant and Its Flocculation Capability
摘要
Abstract
Nonionic polyacrylamide (PAM-APAP) flocculant with good flowability was prepared by inverse emulsion polymerization using acrylamide(AM) and AE200 type polymerizable alkylpheol polyether (APAP)as monomers.The factors affecting the polymerization were studied.The optimum preparation conditions are as follows:total monomer mass fraction 35％,m(AM) ∶ m(APAP)=9.0 ∶ 1.0,mixed emulsifier Tween 80+Span 80 dosage 7％ of the total mass of oil and water,m(Span80) ∶ m(Tween80)=7.0 ∶ 1.5,V50 dosage 1.5‰ of the total monomer mass,reaction temperature 50℃.Comparing with other flocculants,PAM-APAP has better flocculation effect with less dosage.When the PAM-APAP dosage is 100 mg/L,the removal rates of turbidity and oil from polymer flooding wastewater are 87.9％ and 89.5％ respectively,in addition,the floc is not viscous.关键词
