Abstract

The fast-growing Zara plant (a putative hybrid of Pennisetum purpureum Schumach.) is usually planted for cattle fodder. For the first time, Zara plant was evaluated for its pulping potential based on anatomical, chemical, and morphological characteristics. This plant was characterized by an acceptable amount of α-cellulose (40.32%) and lignin (18.4%), with medium fiber length (1.09 mm). Soda–anthraquinone (AQ) pulping of Zara plant was investigated. Anatomically, stems of Zara plant had porous structure, mainly composed of vascular bundles surrounded by parenchyma tissue. Consequently, they were easier to delignify and defibrate, and a pulp yield of 46.54% was obtained, with kappa number 15.45 under the conditions of 14% alkali charge for 120 min of cooking at 150 °C. Good papermaking properties were observed, the tensile index was 78.9 N.m/g at 43 °SR. The resulting pulps showed good bleachability in elemental chlorine-free (ECF) bleaching sequences (D0(EP)D1). Pulp brightness of 81.5%, with the viscosity of 16.0 mPaS, was obtained, with the consumption of 25 kg ClO2/ton of pulp.

zara厂的制浆造纸性能

快速生长的Zara植物（一种公认的紫色狼尾草的杂交种）通常被种植作为牛饲料。首次根据解剖、化学和形态特征对Zara植物的制浆潜力进行了评估。该植物的特征是可接受量的α-纤维素（40.32%）和木质素（18.4%），纤维长度中等（1.09mm）。对扎拉植物碱-蒽醌（AQ）法制浆进行了研究。在解剖学上，扎拉属植物的茎具有多孔结构，主要由薄壁组织包围的维管束组成。因此，它们更容易脱木素和纤维化，在150°C下烹饪120分钟，在14%碱量的条件下，获得了46.54%的纸浆产率，卡伯值为15.45。观察到良好的造纸性能，在43°SR下的拉伸指数为78.9 N.m/g。所得纸浆在无元素氯（ECF）漂白序列（D0（EP）D1）中显示出良好的漂白性。在消耗25kg ClO2/吨纸浆的情况下，获得了81.5%的纸浆白度，粘度为16.0mPaS。
