摘要
利用NS 51003漆酶对美国旧瓦楞纸箱(AOCC)浆进行生物酶处理,研究了漆酶处理的酶促反应条件对AOCC浆强度性能的影响。研究结果表明,漆酶处理的最佳酶促反应条件为:漆酶用量16 U/g浆;浆浓5%;pH值7;反应温度:室温;反应时间1 h;并通空气。在此条件下采用漆酶处理AOCC纸浆,其湿抗张指数和湿环压指数均有明显的提高。
The American Old Corrugated Containers(AOCC)was treated with laccase NS 51003. The optimum conditions of laccase treatment were studied. It was found that the optimum conditions for laccase treatment were : the charge of laccase 16μ/g pulp, pH 7, room temperature, pulp consistency 5% and reaction time 1h. The results also showed that wet ring crush compression strength (RCT) and wet tensile strength of AOCC treated with laccase increased significantly compared to control handsheet.
