摘 要: 在实验室第一阶段研究的基础上,对以连二亚硫酸钠为添加剂的旧报纸低碱度脱墨碎浆新工艺做了进一步的深入研究,并在工厂生产线上做了中试。试验结果表明,连二亚硫酸钠低碱度脱墨碎浆工艺的制浆成本低于过氧化氢脱墨碎浆工艺,在二者使用量相同的情况下,Na2S2O4脱墨碎浆工艺脱墨浆的白度更高。 Some more studies on the new deinking technology with hydrosulphite at low alkalinity was continued based on the authors' first stage work. The new technology has been tested in a small mill. Some latest research results were reported.
