粉碎处理提高竹溶解浆的反应性能
Improving the reactivity of bamboo dissolving pulp by grinding
摘要
Abstract
The study was aimed at improving the reactivity of bamboo dissolving pulp by grinding treatment.The effect of grinding time on reactivity was investigated by analyzing the Fock reactivity, degree of beating and degree of polymerization.Pulp quality was further characterized by fiber morphology, crystal structure and appearance.The results showed that the Fock reactivity reached 80.2% and increased by 17.4% after 6 min of grinding treatment;degree of polymerization decreased from 529 to 515 and only declined by 2.6%.The grinding treatment induced the formation of fuzzy fiber and increased the cross section of fiber by cutting and dispersing, which led to add the fines content and specific surface area and increase the beating degree, decreasing fiber length, and the crystallinity of cellulose at the same time.The accessible surface area of bamboo pulp was increased, which led to the enhancement of reactivity since keeping the polymerization degree at high level.关键词
