| 摘 要： | 本研究选用三种电荷密度相同而分子量不同的聚二甲基二烯丙基氯化铵(PDADMAC),考察了其作为固着剂控制碱性过氧化氢漂白机械浆(APMP)中溶解物与胶体物(DCS)时的湿部化学行为。结果表明:分子量越大的PDADMAC越容易与浆料中悬浮细小物质(包括胶体物质)作用,使浆料的特性发生更大的变化;相反分子量越小的PDADMAC越容易与溶解物质作用,降低白水的COD含量。

| Abstract: | Fixing agent is used to control the accumulation of dissolved and colloidal substances(DCS) in white water closed system.But it is obscure how charge density and molecular weight of a fixing agent affects its application.In this study three kinds of polydimethyldiallylammonium chloride(PDADMAC) with same charge density but different molecular weights were used as fixing agent to control the dissolved and colloidal substances in an alkaline peroxide mechanical pulp(APMP).The results showed that PDADMAC with ... |
