摘　　要：本文以ONP/OMG混合废纸为脱墨对象,研究了17种表面活性剂及其复配物的中性脱墨性能。结果表明,AEO-7、AEO-20和平平加A-20不仅在单独脱墨时表现出良好的脱墨性能,而且还具有与其他表面活性剂的良好的配伍性,很适合用作中性脱墨剂的组分,以它们为主要组分的THJ系列中性脱墨剂具有良好的脱墨效果,如用中性脱墨剂THJ-4,可以使脱墨浆白度提高9.4%ISO,而浮损率只为10.4%。Under the neutral condition, the deinkability of 17 kinds of surfactants and their mixtures to ONP/OMG mixed waste paper was studied. The results showed that the AEO -7, AEO -20 and peregal A -20 were suitable for the component of neutral deinking agent, not only because of the good deinkability when used by oneself, but also the good compatibility with other surfactants. THJ series neutral deinking agents which took them as the main component had good deinking effect. For example ,by neutral deinking agent THJ -4, the brightness of deinking pulp could be enhanced 9.4% ISO ,as the loss rate of fiber in flotation process was only 10.4%.
