摘　　要：本文介绍了碱法蔗渣制浆废液与丙烯酸、甲基丙烯酸甲酯、丙烯酰胺、一种有机络合剂等直接反应，制备改性碱法制浆废液的方法，研究了该改性制浆废液在膨润土浆和聚合物泥浆中的降粘性能，探讨了降粘机理。结果表明，该改性制浆废液在聚合物泥浆中的降粘能力大大超过ＦＣＬＳ，在膨润土浆中的降粘能力在加量超过约１８０ｍｇ／ｌ后略高于ＦＣＬＳ。A modified alkaline pulp black liquor (MAPBL) is prepared through reaction of a black liquor concentrate containing 23% lignin directly with acrylic acid, methyl methacrylate, acrylamide, an organic complexing agent, Fe 2(SO 4) 3 and other reagents and its viscosity reducing property in mud is investigated. MAPBL reduces apparent viscosity (AV) of polymer mud in much more extent than FCLS does and the viscosifying effect of the polymer in mud disapears when MAPBL concentration is >600mg/l. At use levels 180—1000 mg/l MAPBL reduces AV of clay mud slightly more than FCLS does and MAPBL <180 mg/l viscosifies the clay mud. The experimental results are discussed and reasoned.
