淀粉酶和木聚糖酶用于铜版纸协同脱墨的研究.docxVIP

摘要 废纸的回收再利用的应用曰益广泛，而废纸在加工中一个重耍的工艺环节就 是脱墨。传统化学法脱墨已经在实际生活中得以应用，脱墨效果也很佳，但对于 生成后的纤维损害却比较大，纤维得率降低，导致纸张性能有一定的缺陷，对废 水污染也相对严重。相对于它來讲，酶法脱墨不但拥有良好的脱墨效果，脱墨后 生成的纤维得率高，造岀的纸成纸性能好，11能减轻废水污染的负荷。因此也受 到广大人们的普遍关注。 木文主要探究淀粉酶和木聚糖酶对铜版纸的脱墨效杲，对影响其脱墨效果酶 的用量、温度和反应时间等参数进行优化，进而确定淀粉酶和木聚糖酶脱墨的最 佳工艺条件。将淀粉酶和木聚糖酶进行复配，以淀粉酶为主，通过淀粉酶和木聚 糖酶配比的确定，获得比单酶脱墨效杲更好的复合酶淀粉酶/木聚糖酶。 关键词：脱墨；淀粉酶；木聚糖酶 Abstract The reuse of waste paper recycling is increasingly widespread, The paper in processing is an important aspect is the de-inking process? Traditional chemical dcinking has been applied in real life, dcinking effect is also very good, but after generation fiber damage than larger fibers yield decreased, resulting in paper properties have some flaws, is also relatively severe pollution of water . With respect to its terms, not only has a good dcinking enzymatic dcinking effect, fiber and high yield after inking generated good performance create the paper into the paper, and can reduce the wastewater pollution load? So also been widespread concern of the majority of people? Paper mainly explored amylase and xylanase on coated paper deinking effect, affecting their deinking amount of enzyme, temperature and reaction time and other parameters arc optimized, and to dctcnninc the amylase and xylanase dcinking most good conditions. The amylase and xylanase enzyme complex to amylase mainly through amylase and xylanase ratio is determined to get a better effect than single enzyme dcinking enzyme amylase / xylanase .
