摘　　要：考察了商品淀粉酶对废纸箱二次纤维磨浆的促进作用。结果表明磨浆可显著提高废纸箱二次纤维的机械强度。淀粉酶用量为1%时二次纤维的环压指数和抗张指数分别比空白样提高18.3%和15.6%。淀粉酶预处理和磨浆的一个重要作用是去除二次纤维的微小纤维和杂质。The promoting effects of commercial amylase on refining of secondary fiber from old carton were investigated.The results show that the refining can obviously increases the mechanical strength of the secondary fibers. By adding 1%of amylase in refining process the ring crush index and tensile index of the refined secondary fibers are increased by 18.3%and 15.6%,respectively,compared with those of controlled sample.One of the important roles of the amylase played in pretreatment and refining is to remove fines and impurities from the second fibers.
