摘　　要：研究了新型表面活性剂十二烷基糖苷在浮选脱墨工艺中的应用。对碎浆转数、碎浆温度、碎浆浓度等因素对脱墨效果的影响进行了分析。最终,确定废新闻纸浮选法脱墨比较适宜的工艺条件为:碎浆时,氢氧化钠:1.5%、硅酸钠:3%、过氧化氢:2%、表面活性剂:0.4%、EDTA:0.2%、碎浆转数50000转、碎浆浓度:4%、温度:60℃;浮选时,浮选浓度:0.5%、表面活性剂:0.4%、浮选时间:15min、洗涤采用80目铜网洗涤一次、洗涤浓度:0.5%,其中表面活性剂为十二烷基糖苷、十二烷基苯磺酸钠按1:1复配得到。In this paper,the new surfactant twelve APG（ alkyl polyglucoside） was applied in flotation deinking process. The effects of pulping speed,pulping temperature,pulp consistency and other factors on the deinking effect were analyzed. It was found that the suitable technological conditions of flotation deinking of waste newspaper were： in the process of pulping,sodium hydroxide 1. 5%,sodium silicate 3%,hydrogen peroxide 2%,surfactant0. 4%,EDTA 0. 2%,pulping revolution 50000 r,pulping consistency 4%,temperature 60℃; in the process of flotation： pulping consistency 0. 5%,surfactant 0. 4%,flotation time 15 min,washing one time with 80 mesh of copper net,washing consistency 0. 5%,and the surfactant was obtained by mixing 1： 1 twelve APG： SDBS（ sodium dodecyl benzene sulfonate）.
