摘要
在草浆酶改性过程中,在一定的酶处理条件下,酶处理强度中的酶用量是影响草浆滤水性能的关键因素.当草浆酶改性的酶用量是以CMC酶活力作为添加基准时,其纸浆滤水性能的改善与酶用量线性相关程度最高.纤维素酶酶系使草浆改性的最佳酶处理强度为:每克纸浆酶用量为4U、酶处理时间0.5h.适当的酶处理,在保持纸浆原强度的情况下,纸浆的滤水性能得到了明显改善.
Bleached wheat straw pulp was treated with cellulase systems under the optimized conditions. The results showed that the optimum treatment intensity of the pulp with cellulase systems is enzyme dosage 4 U/g and treatment time 0.5 h. The enzyme dosage is the key factor on the improvement of drainage property of the pulp. The improvement of pulp drainability is mainly related to endoglucanase dosage (CMC'ase)in the cellulase systems. At the treated intensity of enzymatic modification, the enzyme treatment had no substantial effect on the strength properties of the pulp.
