【摘要】：研究了不同渗透剂对桉木化学机械法制浆性能的影响,结果表明:不同类型的渗透剂对桉木浸渍性能的影响差异较大,其中磺化琥珀酸二辛酯钠盐类渗透剂S4对桉木浸渍性能改善程度最高,渗透剂用量为0.4%时,可以使木片的吸液量和Na OH吸收率分别比对照样提高7.34%和9.97%。渗透剂对桉木化学机械浆的性能影响如下:浸渍段添加0.4%渗透剂S4,制取加拿大游离度(CSF)为300 m L的纸浆,可以使磨浆电耗降低10%以上,浆中的细小组分减少9个百分点以上,纤维束减少46%;纸浆的抗张强度、耐破强度及撕裂强度均有不同程度的提高,可分别提高11.4%、14.3%和15.6%,但对纸浆的白度无明显影响。
[Abstract]:The effects of different osmotic agents on the properties of eucalyptus pulping by chemical and mechanical method were studied. The results showed that the influence of different kinds of osmotic agents on the impregnation performance of eucalyptus wood was quite different. The dioctyl sulfosuccinate sodium salt osmotic agent S4 improved the impregnation performance of eucalyptus by 7.34% and 9.97% respectively when the amount of osmotic agent was 0.4. The effect of permeating agent on the properties of eucalyptus chemical-mechanical pulp is as follows: when 0.4% osmotic agent S4 is added in the impregnation section, the pulp with Canadian free degree CSF (300ml) can reduce the power consumption of the pulp by more than 10% and the fine components of the pulp by more than 9 percentage points. The tensile strength, breaking strength and tear strength of the pulp were increased to some extent, which could be increased by 11.4% and 15.6%, respectively, but there was no obvious effect on the brightness of the pulp.
