摘　　要： 本文对不同环氧乙烷加成数的脂肪醇聚氧乙烯醚类非离子表面活性剂在废新闻纸中性脱墨中的应用进行了探讨。同时,还研究了不同非离子表面活性剂之间、非离子与阴离子表面活性剂之间的协同作用,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Y2的协同作用能取得更好的效果,且无机盐W2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。 The ONP neutral deinking performances of several kings of non-ionic surfactants fatty alco-hol polyoxyethylene ether with different EO value were investigated in this paper, Meanwhile, the synergis-tic effects of different non-ionic surfactants, the co-operation of non-ionic surfactants with anionic surfac-tants and the effects ,of different salts added into the above two systems on deinkability were also studied.The results showed that the deinking performance of A7 was good. But the synergistic effect of A7 and Y2was better. In addition, the accession of saltW2 could improve the deinking efficiency obviously, and thebrightness of the deinked pulp was 1.2%ISO higher than that of A7 and Y2.
