摘　　要：超临界氨法对二次纤维的制浆实验表明:氨在185～190℃的超临界状态下,能溶解二次纤维中的木素和油溶性物质,达到制浆的目的。该法可以提高纸浆的打浆度,以及增强纸张的抗张强度和撕裂度,其成纸的物理性能达到工业及文化生活用纸要求。制浆废液可作为含氮和钾的有机肥来使用,或根据去氨的程度应用于化工原料行业。The pulping experiment of secondary fiber through supercritical ammonia method showed that ammonia at supercritieal state of 185-190 ℃ was able to dissolve lignin and oil soluble substance in the secondary fiber to complete pulping process. The degree of beating, tensile strength and tearing strength were increased. The property of paper could satisfy the demand of industrial and cuhural paper. The pulping waste could be used as nitrogen and potash fertilizer or chemical material according to thedegree of eliminating ammonia.
