摘　　要：在实验室研究了抄纸用水循环使用对AKD施胶效果的影响。结果表明,实验室抄纸用水每次循环使用后其电导率、浊度、COD和阴离子度等都有不同程度的增加;实验室循环使用6次的抄纸用水的电导率和CODCr约为循环使用8个月工厂用水的1/30;随抄纸用水COD和电导率的增加,AKD施胶效果迅速降低,且COD对AKD施胶效果的影响比电导率的影响显著;通过添加高电荷密度聚胺复合物可大幅提高AKD的施胶效果,聚胺复合物的作用之一是提高微细纤维等微粒的留着和降低抄纸用水的阴离子度。Effect of recycling papermaking water on AKD sizing was investigated by the method of laboratory simulation.The results showed that each cycle of laboratory papermaking water resulted in increases in conductivity,turbidity,COD and anionic degree to different extents.The amount of COD and conductivity of water recycled for 6 times in laboratory were one-thirtieth of the water recycled for 8 months in a mill.AKD sizing efficiency decreased rapidly with increases of COD and conductivity in the water,and the negative effect of COD was more significant than that of the conductivity.AKD sizing efficiency was improved significantly by adding polyamine complex with high charge density.The role of the polyamine complex is to improve retention of the fines and other particles,and reduce anionic degree in the water.
