OOP Bleaching of Bagasse Black Liquor Pretreated Kraft Pulp 黑液预煮KP法蔗渣浆的OOP漂白
Wood CTMP was bleached with formamidine sulphinic acid ( FAS). By the change of liquor pH and the bleaching results, the solubility and the liquor stability of FAS were studied. 本文用甲脒亚磺酸(FAS)漂白CTMP浆,通过药液pH值变化及漂白效果探讨FAS的溶解性、稳定性。
Sodium perborate ( SPB) is one of the excellent bleaching agents. But it releases active oxygen only in high temperature washing liquor. 过硼酸钠(SPB)是一种良好的漂白剂,但需在较高温度下才能释放出活性氧。
Soda-CT-1 Additive Pulping and TCF Bleaching of Bagasse with Black Liquor Pretreatment 蔗渣黑液预煮烧碱-CT-1助剂法制浆与全无氯漂白的研究
The digestion pollution load, the bleaching pollution load and the physical chemical property of black liquor have been determined. 测定了蒸煮污染负荷、漂白污染负荷和黑液物化性能。
A modality of H2O2 degradation mechanism in urea media was proposed, and the activation energies of different bleaching liquor systems were detected. The research of this paper provides a theoretical basis for urea-H2O process. 提出了H2O2在尿素介质中的分解机理模式,并测出不同漂液体系的活化能,为尿氧工艺提供了理论基础。
Studies on lignin chemistry are very important to pulp and papermaking technology, bleaching technology and spent liquor treatment, and the analysis on lignin structure can provide basic data for the application of lignin. 研究木素化学不仅可以指导制浆造纸技术,漂白技术及废水处理技术的发展,还可以为木素的综合利用提供理论依据。
