摘要：对尾巨桉新鲜木片、储存一定时间的保湿桉木片及风干桉木片进行了P-RCAPMP制浆性能研究。结果表明,均为H2O2用量6.0%、NaOH用量4.0%的条件下,制取加拿大游离度300mL的纸浆,储存1年的保湿桉木片和风干桉木片分别比新鲜桉木片磨浆能耗增加了3.0%和12.5%,制浆得率下降了6.8个百分点和2.9个百分点,纸浆抗张强度下降49%和30%,纸浆白度下降5.1和5.7个百分点;另外,制浆综合废水的发生量及废水的污染负荷都有不同程度的增加。
Eucalyptus urophylla × grandis woodchips stored in different conditions were pulped by using the typical P-RC APMP process. The influences of various storage conditions on its P-RC APMP pulping performance were investigated. A fix pulping conditions such as H2O2 dosage 6.0% and NaOH dosage 4.0% were applied, pulping performance varied with the changing of storage conditions of the Eucalypt chips, the results showed that, at a given Canadian Standard Freeness of 300 mL, comparing to fresh eucalyptus woodchips, 3.0% and 12.5% higher refining energies were consumed by woodchips sealed in plastic bags and kept in a cool room and air dried woodchips after one year storage, respectively, and pulp yields decreased by 6.8 and 2.9 points, pulp tensile strengths decreased by 49% and 30%, pulp brightness lost about 5.1 and 5.7 points respectively, and the pollution loads of their pulping effluent were lower than those of fresh wood chips.
