加入半纤维素以改善不同纸浆的物理和机械性能,是一种绿色工艺
作者(年代):Essam.N。广告,,A.M.A.Nada A.M.El-Masry防止废物产生的最有效方法之一是尽可能确保制造产品所涉及的所有材料都应纳入最终产品[1]。在这项工作中,我们使用了新的趋势 -绿色Chemistry -我们从农业废物和可再生原料如甘蔗渣和棉秆中分离出半纤维素,以防止污染,使用较少的有害化学品,节省溶剂和助剂。这项工作的目的是研究半纤维素和不同的填料添加剂在多大程度上可以通过改善纸张和粘胶纸浆的机械和物理性能。半纤维素是用水溶液碱提取的。从综纤维素和酸水解液(预水解液)中提取的半纤维素。从甘蔗渣中提取粘胶级纸浆;经预水解和NaOH制浆制备去皮和去皮棉秆。采用绿色工艺和经典漂白剂对甘蔗渣、脱皮棉秆粘胶浆进行漂白,并对其机械物理性能进行了研究。甘蔗渣浆脱色时漂白剂用量小于棉秆浆。这是由于棉秆浆中木质素含量较高所致。 The addition of hemicellulose, during the beating process, to both viscose and paper grade pulps improved the physical and mechanical properties of produced paper sheets, where the breaking length increases from 2490 to 3050 m, Burst factor increases from7.6 to13.6 and Tear factor also increase 15.7 to 35.1 in viscose grade pulp (Low Hemicellulose content). We study the effect of adding different fillers such as Oxidized starch, polymer (polymin SK) and CaCO3 to bleached bagasse paper grade pulp and the Physicomechanical properties of paper sheets will studied.
