| 摘 要： | 本文研究了单组分非离子、不同非离子表面活性剂之间和非离子与阴离子表面活性剂之间的协同作用对废新闻纸中性脱墨的影响;以及无机盐对复配体系脱墨效果的影响.结果表明,单一组分A7对废新闻纸的脱墨和纤维性能的改善有良好的效果.A7和烷基硫酸盐的协同作用能取得更好的效果,且无机盐碳酸氢钠的加入可以更加明显地提高脱墨效率,脱墨浆的白度提高1.2%ISO.

| Abstract: | The ONP neutral deinking performances of non-ionic surfactants fatty alcohol polyoxyethylene ether, the synergistic effects of different non -ionic surfactants, and the combination of non-ionic surfactants with anionic surfactants were investigated in this paper. Meanwhile, the effects of different salts added into the above systems on deinkability were also studied. The results showed that the deinking performance of A7 was good. But the synergistic effect of A7 and alkyl sulfate was better. In addition, the accession of salt NaHCO_3 could improve the deinking efficiency obviously, and the brightness of the deinked pulp was 1.2% ISO higher than that of A7 and alkyl sulfate. |
