利用阳离子分散松香胶进行中性施胶,选用了在中性PH值范围中保持较高正电荷密度的聚合氯化铝作留着剂,选用了白度高、粒度小的碳酸钙作填料,改变了传统的酸性施胶,克服了夏季施胶的困难,保证了成纸施胶度的稳定,提高了纸张的平滑度、挺度等物理指标,同时降低了施胶成本,取得了良好的经济效益。
The use of cationic dispersed rosin glue for neutral sizing, the choice of neutral pH value in the higher positive charge density of PAC as a retention agent, the choice of high brightness, small particle size of calcium carbonate as a filler, It changes the traditional acidity sizing and overcomes the difficulty of sizing in the summer. It ensures the stability of the sizing degree of the paper, improves the physical indexes such as the smoothness and stiffness of the paper, reduces the sizing cost and achieves a good Economic benefits.
