摘要
探讨碱性木聚糖酶用于中小径竹KP浆漂白预处理的最佳工艺条件及碱性木聚糖酶预处理对中小径竹KP浆ECF漂白的影响。结果表明,碱性木聚糖酶Unikfect100处理浆的最佳工艺为浆浓度4%,pH值9.0,温度65℃,时间20min,酶用量15.0×10-7mol·s-1g-1浆;对ECF漂白的影响为O-X-D1-EOP-D2漂序的漂白效果优于O-D/C-EOP-D2,在白度相近的情况下,纸浆的粘度及物理强度较高。
The pretreatment condition and the influence of elemental chlorine free （ECF） bleaching of xylanase to bamboo kraft pulp（KP） has been carried out. The results indicate that the best pretreatment condition of enzyme Unikfect 100 is： the consistency is 4%, pH 9.0, temperature 65℃, time 20 min, enzyme dosage 15.0 ～ 10^-7 mol · s^-1 g^-1 thick liquid. The influence of ECF bleaching is that the effect of O - X - D1 - Eop - D2 is better than O - D/C - Eop - D2. At the similar brightness, the former pulp has higher viscosity and intensity.
