摘 要: 溶解浆是一种高纯度的化学浆,是黏胶纤维的主要生产原料。文章介绍了溶解浆的制备方法,包括预水解硫酸盐法、酸性亚硫酸盐法、有机溶剂法以及直接处理化学浆法,评价了不同制备方法所得溶解浆的性质,分析了溶解浆制备和生产过程中面临的关键技术问题,提出了解决方案,并对溶解浆厂实现生物质精炼模式的前景进行了展望。 Dissolving pulp is the most important raw material for viscose production in the textile field. This paper summarized the manufac ture processes of dissolving pulp, e. g, prehydrolysis kraft pulping, sulfite pulping, solvent pulping and chemical treatment of paper grade pulp. The properties of dissolving pulps from each method were discussed and evaluated. Besides, the key technologies related to dissolving pulp manufacture were addressed; some solutions were also suggested. Finally the authors forecasted the promising future of dissolving pulp manufacture based on the biorefinery mode.
