| 摘 要： | 本文利用原子吸收光谱对轻质碳酸钙、高岭土、滑石粉、二氧化钛等常用造纸填料的元素组成进行分析。测定了轻质碳酸钙和高岭土两种填料悬浮液不同浓度下的ξ电位。研究填料的存在对纸浆碱性过氧化氢漂白的影响。结果表明，所用填料悬浮液的ξ电位随着填料加入量的增加而绝对值增加且均为负值，纸浆中不同的填料及其用量对过氧化氢纸浆漂白效果有不同的影响。

| Abstract: | The profile of elements in light calcium carbonate, kaolin, talcum powder and titanium dioxide was analyzed by means of atomic-absorption spectrometer. The Zeta potential of the solution with different charge of fillers was measured. The influence of fillers on alkaline hydrogen peroxide bleaching of recycled fibers was studied. The results show that the negative zeta potential of filler slurry will rise as filler charge increase. Different kinds of fillers and charge have different effects on the pulp hydrogen peroxide bleaching. |
