摘　　要：在书写纸生产中添加聚乙烯胺,可用短纤木浆(LBKP)和杨木化机浆(APMP)替代8%的长纤木浆(NBKP),并减少助留剂用量和磨浆电耗,显著提高保留率而不影响成纸强度,吨纸综合生产成本降低20元。Addition about 3.5 kg·t-1 of PVAm to producing writing paper, we can use LBKP pulp and APMP pulp to replace NBKP pulp by 8 percent, reducing the amount of the retention aid and refining energy, considerably increase the first pass retention meanwhile does not affect the paper strength, the total operation cost saving by 20 yuan per ton.

关 键 词：聚乙烯胺 浆料配比 保留率 成纸强度 生产成本
