摘要
采用动态粘弹仪研究了红麻热机械性质，结果表明，红麻经碱性亚钠预处理后，亲水能力增加，弹性模量下降，软化温度提前，由最大损耗模量推算，适宜的磨浆温度为８０～９０℃，因此，磨浆在常压下即可进行并可获得较好的浆质量。
The viscoehstic property of kenaf was studied with rheovibron. It resulted that the swelling ability increased and the elastic modulus and softening temperature(TG)de-creased after sodium sulfite pretreatment,Calculated by the maximum loss modulus,thCbetter refining temperature should be at 80℃～90℃ So the cooked kenaf can refine at at-mospheric pressure with a good pulp quality.
