摘要
就旧报纸脱墨碎浆工艺影响脱墨浆白度的主要因素做了研究和介绍。高碱度和添加过氧化氢是现行碎浆工段的特点 ,笔者就其优劣性做了分析 ,并报道了针对现行脱墨过程中存在的碱性泛黄
Some factors that strongly affect the deinked pulp (DIP) brightness in the old newspaper(ONP) pulping process are studied. Some unoptimized operation in current ONP deinking technology such as high alkalinity and addition of peroxide are discussed .The latest research results in the aspects discussed are introduced.
