摘要
随着废纸质量变差,新闻纸用废纸脱墨浆的白度变得不稳定及白度下降,于是在新闻纸抄造中添加荧光增白剂被广泛应用。本文研究了二磺酸类荧光增白剂对废纸脱墨浆的白度增益影响,及用量增加后对造纸湿部助留、助滤、电位、纸张性能的影响。
The brightness of wastepaper deinking pulp （DIP） is becoming unstable and declining because of the worse and worse wastepaper＇s quality. Optical brightening agents （OBA） have been widely used in newsprint making. This article researched the influence of disulfonic OBA to DIP brightness increasing. This article also studied the influence to paper wet - end in retention, filtration, potential and paper properties if increasing the use of OBA.
