摘　　要：探究了水力碎浆过程中材料质量分数、搅拌时间、搅拌速率和温度等因素对纸纤维分离率的影响,并在碎浆体系中引入了表面活性剂、无机盐和无机碱3类活性介质.结果表明,添加活性介质后,纸纤维分离率提高了7.31%~38.80%,长纤维比例提高了11%.其中,表面活性剂十二烷基苯磺酸钠的使用效果最好.This study investigates the effects of material mass fraction,stirring time,stirring rate and temperature on the separation rate of paper fibers in the process of hydraulic pulping.Additionally,three types of active media of surfactants,inorganic salts,and inorganic bases were introduced into the pulping system.The results showed that after adding active media,the separation rate of paper fibers increased by 7.31%~38.80%and the proportion of long fibers increased by 11%.Among them,the surfactant sodium dodecyl benzene sulfonate exhibited the best application effect.
