| 摘 要： | 本文采用Ｈ２Ｏ２单段、Ｈ２Ｏ２两段、次氯酸盐与Ｈ２Ｏ２加酸处理三段漂程对红麻皮低温烧碱－ＡＱ浆的漂白工艺进行了研究。结果表明：采用Ｐ单段漂，用３％的漂剂可使漂至５６．６％；总漂剂用量不变，控制Ｐ－Ｐ两段漂中Ｐ１和Ｐ２的比例，在Ｐ１：Ｐ２〈１的情况下，可获得６０．２％的白度；ＨＡＰ漂程，可用较少的漂剂获得白度８２．４％以上的漂白浆，且白度稳定性好，浆张物理强度较高。

| Abstract: | The bleachability of low temperature SODA-AQ pulp from kenaf bast with one-stage hydrogen peroxide (P), two-stage hydrogen peroxide (P-P) and HAP three kinds of sequences was studied. The results showed: The pulp can bebleached to 56. 6% brightness by using single stage bleaching of the peroxide connsumption about 3%. Through controlling the proportion of P1 and P2 in P-P sequence undercondition of P1:P2<1, a 60. 2% brightness can be reached. With HAP sequence, a brightness over 82. 4% was easy to abtain, and less bleaching chemicals required, better brightness stability and higher pulp physical strength. |
