| 摘 要： | 采用NOVOZYM476纤维素酶对思茅松漂白KP浆的酶促打浆进行了研究,探讨了该酶在不同反应体系下对思茅松漂白KP浆打浆性能、纸浆物理性能和纤维形态的影响.结果表明,NOVOZYM476纤维素酶在pH值4.8和温度50C条件下,各组分酶活都达到最大值;当酶用量为0.05u/g时,能够显著提高打浆性能,降低打浆能耗,且对纸浆物理性能没有太大影响;酶处理最佳温度范围为50～60℃、最佳pH值为4.8～5.8;酶处理使纤维平均长度降低、平均宽度和平均扭结指数增加.

| Abstract: | In this paper, enzymatic refining of Simao pine bleached kraft pulp with the high performance cellulose NOVOZYM 476 was studied. The effects of this cellulase on the refining performance & physical properties of the bleached softwood kraft pulp in different application conditions were discussed. At the first, the effects of temperature and pH value on the four different enzyme activities of NOVOZYM 476 cellulose such as FPA and Cx were investigated. Then, the effect of dosage of this cellulose on enzymatic ... |
