Novozymes N476、PulpzymeHC及复合酶用于漂白针叶木浆打浆前预处理,对纸浆的白度、打浆性能及成纸性能进行了研究。结果表明:漂白针叶木浆酶预处理对打浆性能及成纸性能有重要影响,复合酶较适合于漂白针叶木浆酶预处理,Novozymes N476在浆的酶预处理中起主要作用,PulpzymeHC起辅助作用。酶预处理有助于提高纸浆白度,PulpzymeHC提高浆白度效果较Novozymes N476和复合酶更为显著。
Novozymes N476, PulpzymeHC and complex enzymes were used to bleach softwood pulp pre-pulp pretreatment. The whiteness, beating properties and paper properties of pulp were studied. The results showed that pretreatment of bleached softwood pulp had an important influence on the beating performance and the properties of the paper. The composite enzyme was more suitable for the pretreatment of bleached softwood pulp. Novozymes N476 played a major role in the enzymatic pretreatment of pulp. PulpzymeHCHC effect. Enzymatic pretreatment can help to improve the whiteness of pulp. PulpzymeHC is more effective than Novozymes N476 and complex enzyme in improving the whiteness of pulp.
