研究了几种生物酶和纤维素结合域(cellulose-binding domains)对旧箱纸板纸浆及其成纸性能的影响,探讨了酶用量和反应时间对酶处理效果的影响,同时衡量了酶对不同长度纤维的作用。结果表明,实验所用的生物酶均能改善浆料滤水性能;大多数情况下,滤水性能的提高以牺牲成纸强度为代价,但是使用纤维素结合域处理浆料可使浆料滤水性能和成纸强度性能同时得到提高。 The effects of several enzymes and cellulose-binding domains on the properties of pulp and paper of old cardboard boxes were investigated. The effects of enzyme dosage and reaction time on the enzyme treatment were also studied. The role of fiber length. The results showed that all the enzymes used in the experiment can improve the water filtration performance of the slurry. In most cases, the improvement of the filtration performance is at the expense of the strength of the paper. However, Performance and paper strength at the same time improve performance.
