摘要： 测定了3种速生黑杨枝桠材(ZY)的纤维形态和化学组分,并对其碱性过氧化氢机械浆(APMP)制浆性能进行了初步探讨。纤维形态分析结果表明,纤维平均长度0.6mm,宽度20μm,长宽比值30,壁腔比值0.4～0.6,含细小组分10%～20%,纤维粗度8～10mg(以100m计)。化学组分分析结果显示(均以质量分数计):1% NaOH抽出物22%,苯-乙醇抽出物2.0%,硝酸-乙醇纤维素44%～47%,聚戊糖24%～25%,酸不溶木质素18%～21%。速生黑杨枝桠材的壁腔比和纤维粗度较小,细小组分含量少,抽出物、木质素和聚戊糖含量相对较低,这些特点有利于制浆造纸生产及成纸性能;但其纤维粗短,长宽比值小,对成纸的物理强度显著不利。采用APMP工艺对速生黑杨枝桠材制浆,结果表明枝桠材(去皮)APMP浆的成纸强度性能明显好于枝桠材(带皮)APMP浆,但与主干材相比还有一定差距。

Abstract: Fiber morphology, chemical composition and alkaline peroxide mechanical pulp (APMP) properties of three kinds of fast-growing black poplar(Populus nigra) crotches(ZY)were studied. Results of fiber morphology analysis are as follows: average fiber length 0.6mm, fiber width 20μm, fiber length-width ratio value 30, cell wall thickness-lumina ratio 0.5-0.6, fine content 10%-20%, fiber coarseness 8-10mg (based on 100m). Results of chemical composition are as follows: 1% NaOH extractives 22%, benzene-ethanol extractives 2.0%, nitro-ethanol cellulose 44%-47%, pentosan 24%-25%, acid insoluble lignin 18%-21%. The results showed that fast-growing black poplar crotches have smaller cell wall thickness-lumina ratio and fiber coarseness, less fine content, lower extractives content, low lignin content, low pentosan content, which are favorable for paper- and pulp-making. However, physical strengths of the paper are significantly adverse because of the short fiber length and small fiber length-width ratio. APMP pulps from fast-growing black poplar crotches using APMP process are obtained. The results show that the APMP pulp strength properties of crotches without bark are superior to crotches with bark, but inferior to bodywood.

Key words: black poplar, crotches, fiber morphology, alkaline peroxide mechanical pulp
