摘　　要：海藻是海洋中含有丰富纤维的植物,通常应用在食品、医药等领域。浒苔是海藻的一种,在中国的黄海及渤海湾地区大量存在,但尚未得到全成分的有效利用,一定程度带来了相应海域的污染。本文主要是针对在青岛海域取样的浒苔进行酸、碱、漂白预处理后,探讨其纤维成分在添加不同比例时对阔叶浆及废纸浆造纸性能的影响。结果表明,漂白法预处理浒苔效果最佳;浒苔纤维添加比例从0到30%增加的过程中,随着添加比例的增加,与阔叶浆及废纸浆复合后纸张的抗张强度、耐破度、撕裂度等物理性能均有所改善。Seaweed is a type of fiber rich, marine plant. Usually it is used in food, medicine and related fields. Enteromorpha is a type of seaweed, which exists in the bay area of Huanghai Sea and Bohai Sea. This experiment was mainly to pretreat Enteromorpha collected from Qingdao sea area, and to study the effects on paper properties by adding various proportions of Enteromorpha fibers into pulp. The results indicated that bleaching pretreatment of Enteromorpha was the best method among the acidic, alkaline and bleaching ones. When the pretreated algae fibers were added up to 30%, almost of the tensile strength, high bursting strength, tear strength and other physical properties of bleached hardwood paper and recycled paper showed rising trend.
