中文摘要：
本实验主要从脱墨浆的浮选自度、残余油墨、胶黏物和纤维流失等方面分析了改性膨润土脱墨剂对ONP的脱墨效果，并采用皂类型脱墨剂、表面活性剂复配型脱墨剂与之对比，实验结果显示，改性膨润土脱墨剂对ONP的浮选白度增值为8．70％ISO、残余油墨降值（ERIC值）为610．00mg／kg、胶黏物降值为241个／kg、纤维流失为0．64％，在三种脱墨剂中有一定的优势。
英文摘要：
This paper discussed the effect of clay-type deinking agent on the brightness, residual ink, stickies and fiber loss of ONP, and it also compared it with soap-type deinking agent and surfactant mixed deinking agent. The results showed that after treatment by clay-type deinking agent, the brightness of ONP increased by 8.7% ISO, re- sidual ink value（ ERIC value） reduced 610mg/kg, the number of stickles decreased 241 per kilogram and fiber loss of ONP was 0.64%. Clay-type deinking agent has best deinking performance among three deinking agents.
