摘　　要：在生产含有机械浆或废纸浆的纸张过程中,浆料中含有的大量溶解物和胶体物质(Dissolved and colloidal substances,简称DCS)被带入纸机抄造系统。随着白水系统封闭循环程度增加引起DCS的积累,给纸张抄造和纸张质量带来各种负面影响。因此,为了消除或减轻DCS所引起的不良影响,必须采取措施去除或控制系统中的DCS。本文主要论述了采用化学方法控制DCS的最新研究进展,重点介绍了固着剂的使用,包括各种固着剂的作用效果、固着机理、影响因素和对纸张质量的影响。In the production of paper from mechanical pulp or recycled pulp, a large amount of dissolved and colloidal substances （DCS） are carried over into the papermaking system. The accumulation of DCS during the papermaking operations due to the closure of process water systems gives various detrimental impacts on the papermaking process and the resulting paper products. Thus it is indispensible to remove or control the DCS in order to overcome or alleviate their negative influences. This review mainly discusses recent advances in control of DCS by chemical methods, and the application of fixatives is emphasized, including their functional effectiveness, mechanism, influencing factors, and influences on paper products.
