胶黏物控制剂在涂布白面牛卡纸生产中的应用

Stickies control agent used in production of coated white-face craft cardboard

以废纸制浆生产线的两个工艺环节(长纤热分散出口、短纤多盘入口)为试验点,添加两种胶黏物控制剂Bandsurf 160(本文简称A)和Bandisp 119(本文简称B)配合进行控制研究。添加胶黏物控制剂后,检测并分析了底层网下白水浓度、保留率、电导率、阳离子需求量。统计了添加胶黏物控制剂前后两个时间段内,断纸次数及断纸时间、成纸单位面积内胶黏物和杂质点个数等数据。综合纸机生产情况和成本分析可见,当胶黏物控制剂A和B的最佳投入量为1.1kg/t绝干浆和0.6kg/t绝干浆时,对底层浆料中的黏性物质起到了良好的控制效果。

Adding two kinds of stickies control agents Bandsurf 160（herein referred to as A） and Bandisp 119（herein referred to as B） in both aspects of the process of waste paper pulp production line（long fiber heat dispersion outlet, short fiber multi-plate entrance） for a experimental research. After adding stickies control agents, detecting and analyzing the concentration of white water, retention rate, conductivity, cationic demand under the bottom wire. Statistics was made on the frequency and timing of breaks when adding stickies control agents before and after, the number of stickies and impurities in per unit area of paper. Analysis on production and cost shows that, when the optimum inputs of A and B is 1.1 kg/t and 0.6 kg/t oven dry pulp, the underlying in the slurry viscosity material has played a very good control effect.
