摘　　要：根据表面活性剂特性对9种类型表面活性剂进行了遴选,选出其中7种并进行单一表面活性剂的脱墨试验,优选出效果较好的5种复配。对优选复配配方3进行了工艺条件正交实验,制定出最佳工艺条件是A3B2C1D3,即浆浓为9%、脱墨剂用量为0.8%,脱墨温度为50℃,脱墨时间为50 min,脱墨后新闻纸浆料白度高达56.1%。According to the characteristics of the 9 types of surfactants, 7 kinds of them were selected for deinking test. 5 kinds of them with good effect were selected to compound. The optimized compounded formulation 3 was pickup for orthogonal experiment with different technical conditions. The optimized technical conditions was found to be A3B2C1D3, which is concentration 9%, deinking agent 0.8%, deinking temperature 50 ℃, and deinking time 50mins. After deinking, the whiteness of the newspaper pulp reaches as high as 56.1%.
