| 摘 要： | 不添加任何化学助剂,在不同汽爆压力下进行棉秆解纤,将解纤后的纤维热压制成无胶纤维板.分析了汽爆压力对棉秆纤维形态、化学成分以及无胶纤维板产品性能的影响.结果表明,随着汽爆压力的增大,纤维分离程度提高,纤维中游离酸、游离糖及游离醇的质量分数含量增加,试板的内结合强度增大,但静曲强度和弹性模量则减小.

| Abstract: | Cotton stalk fibers were obtained through the steam-explosion pulping process and binderless fiberboards were produced from the fibers without any chemical additives. The effect of steam-exploded pressure on fiber dimension,chemistry components,and board properties was investigated in this paper. The results showed that higher steam pressure produced finer fibers with higher sugar,acids,and higher alcohol contents. It was also observed that the internal bonding strength of the binderless fiberboard was impr... |
