摘　　要：研究了复合纤维素酶对磨木浆的酶处理。研究发现,复合纤维素酶处理可以改善磨木浆的滤水性能和强度,并在一定程度上提高浆的白度。较优的酶处理条件为酶用量600ppm/g绝干浆,纸浆浓度1.0%,温度45℃,初始pH值7.0,时间60min,此时得到最佳的打浆度改善值,且浆的白度和强度指标有所提高。Research of complex cellulases treatinggroundwood pulp was carried out. It was proved that en- zymatic treatment could make drainage eapacity and strength of groundwood pulp better, and improve brightness to a certainextent. The optimum conditions were as follows, the dosage of 600ppm/g BD pulp, the concentration of 1.0%, the beginning pH value of 7.0, the temperature of 45℃, and the process time of 60min. After treatment of complex cellulases, the best promotion of drainage turn out with brightness and strength improved a little.
