【摘要】 我国利用废旧书刊纸脱墨,存在脱墨不净,白度不够,墨点较多等问题。本文报道了对现有脱墨剂配方的筛选,加入AEO表面活性剂,并改进工艺条件:NaOH质量分数2%,Na2SiO3质量分数3%,H2O2质量分数1%,AEO-10质量分数0.2%,AEO-35质量分数0.2%,十二烷基苯磺酸钠质量分数0.4%,熟化时间65 min,熟化温度55℃。更多还原

【Abstract】 Deinking papers generally used in our country are defected in unclear,whiteness insufficient,and over-dotted.This paper reports the improvement of domestic deinking prescriptions by adding surface active agent AEO and modifying the technology conditions as follows: NaOH,2%,Na₂SiO₃,3%,H₂O₂,1%,AEO-10,0.2%,AEO-35,0.2%,LSA,0.4%.Curing time 60,minutes,Curing temperature,55℃.更多还原
