| 摘 要： | 对慈竹单段漂白和多段组合漂白性能进行了系统研究,提出了慈竹化机浆漂白至71%以上白度的工艺。研究结果表明,H2O2总用量10%,慈竹化机浆经单段H2O2漂白,白度只能达到64.7%~65.0%;两段H2O2漂白具有较高的漂白效率,漂白浆白度达到66.6%~67.1%;总漂剂用量为12%的三段组合漂白,结束段分别使用H2O2、FAS和Na2S2O4不同漂白方式,FAS漂白效率最优,白度达到72.9%;其次是H2O2漂白,白度为71.9%;以FAS为结束段的漂白,与本色慈竹化机浆相比,抗张指数、耐破指数和撕裂指数分别提高200%~300%、250%~300%和250%~270%。采用碱性Na2SO3化学预浸渍,两段H2O2漂白加一段FAS漂白的三段组合漂白,慈竹化机浆可漂白至71%以上的白度。

| Abstract: | Bleaching of chemimechanical pulps from a bamboo species Neosinocalamus affinis(Rendle) Keng f to a higher brightness by single-and multi-stage processes was discussed in this paper.By using 10% H2O2,the bamboo pulps were only able to bleach to a brightness of 64.7%~ 65.0% ISO in single stage process.Bleaching efficiency was improved by using two-or three-stage process.The brightness of 66.6%~67.1% ISO was obtained by two-stage bleaching at 10% H2O2 charge in total.Bleaching properties of the bamboo high yi... |
