| 摘 要： | 选用4种分子质量相同而电荷密度不同的聚二甲基二烯丙基氯化铵(PDADMAC),考察了这4种PDADMAC作为固着剂控制碱性过氧化氢漂白机械浆(APMP)中溶解与胶体物质(DCS)时的湿部化学行为。结果表明,电荷密度越高的PDADMAC不仅更容易和浆料中的DCS作用,而且更容易被纤维吸附,同时其去除白水中的悬浮固体物质、DCS、以及COD的效果越好。

| Abstract: | Fixing agent is used to control the accumulation of dissolved and colloidal substances(DCS) in closed white water system,but how the charge density and molecular weight of a fixing agent affect its application efficiency is not clear in literature.As one of the two parallel studies,this study used four PDADMACs with same molecular weight but different charge densities as fixing agent to control the DCS in an alkaline peroxide bleached mechanical pulp(APMP).The results showed that PDADMAC with higher charge ... |
