废新闻纸脂肪酶脱墨方法的研究

摘要

Obvious deinking effect was observed when using the lipase liquid to treat old newsprint.Compared with conventional chemical method,brightness of deinked pulp with lipase was increased by 2.45 percentage point,and the durt removal was higher,with dirt count decrease of 123.9 mm2/m2,and total fiber yield was improved by 6.69 percentage point.%利用脂肪酶液对废新闻纸进行脱墨,效果明显。与常规化学法相比,脱墨浆ISO白度提高了2.45百分点,尘埃度的降低也明显优于常规化学法,达123.9 mm2/m2,纤维的总得率提高了6.69百分点。
