摘要
近几年来,高得率浆的生产与应用技术逐渐受到人们的重视,并得到大力发展。但是,高得率浆的光致返黄现象成为限制其在高附加值纸种中应用的一个主要因素。本文主要论述高得率浆光致返黄的机理和提高高得率浆光学稳定性的途径,探讨了荧光增白剂的增白机理以及对高得率浆光致返黄的抑制作用。
In recent years, great development have been obtained on production and application technologies of high yield pulps （HYPs） . However, HYP＇s light-induced brightness reversion has become one of the major drawbacks to lim- it its application in value-added paper grades. In this paper, the mechanisms on light-induced brightness reversion and some approaches to inhibit HYP＇s yellowing have been summarized. Also, the brightening mechanism of fluorescent whitening agent and its application against the brightness reversion of HYPs are discussed.
