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。
The effects of penetrating agent on the properties of eucalyptus woodchips chemi-mechanical pulping were studied.The results showed that the performances of different type of penetrants were quite different in the eucalyptus woodchips chemimechanical pulping properties.Among these,sodium diethylhexyl sulfosuccinate penetrant exhibited the best performance on improving the impregnation of eucalyptus woodchips.With the dosage of penetrant of 0.4%,the chemical liquor absorption amount and Na OH absorption rate of wood chips respectively increased by 7.34 % and 9.97 % respectively,if they were compared with the blank groups.At the Canadian standard freeness（CSF） level of 300 m L,with the addition of 0.4 % sodium diethylhexyl sulfosuccinate at the impregnation stage,the refining energy consumption and shives content in pulp were reduced by over 9 % and 46 %,respectively,if they were compared to the control pulp sample.And the tensile strength,burst strength and tear strength were increased by 11.4 %,14.3 % and 15.6 %,respectively,without losing brightness.
