摘要
烯基琥珀酸酐(ASA)和烷基烯酮二聚体(AKD)是造纸中常用的2种反应型中/碱性施胶剂。相比AKD,ASA具有反应活性高等诸多优点,但其反应性施胶机理至今仍然存在着争议。该文就近年来有关ASA乳化及其施胶理论的发展情况进行了介绍。
Alkenyl succinic anhydride（ASA） and alkyl ketene dimer（AKD） are both reactive sizing agents which are generally used under neutral or slightly alkaline papermaking conditions. Compared with AKD, ASA has many advantages such as its high reactivity. However, the cellulose-reactive mechanism of ASA sizing is still controversial. The development of ASA emulsification technique and its sizing mechanism in recent years are introduced in this paper.
