| 摘 要： | 探讨了在弱碱性条件下聚乙烯胺(PVAm)对CaCO3加填的芦苇浆和废纸浆的助留助滤效果．实验结果表明：PVAm在两种浆中都有非常显著的助滤．助留效果，且在芦苇浆中的助滤效果大于废纸浆．PVAm在芦苇浆中对纤维的助留效果不如废纸浆，但对CaCO3的助留效果高于废纸浆．

| Abstract: | Effects of Polyvinylamines(PVAm) on drainage and retention of the reed chemical pulp and the waste pulp were investigated under the neutral papermaking condition. The results showed that the addition of PVAms improved greatly drainage and retention of the two slurries containing CaCO 3.The drainage effects of PVAms in the reed chemical pulp was larger than those in the waste pulp. Though PVAm exhibited worse retention effects of the fiber in the bleached chemical reed pulp, the retention effects of calcium carbonate in the bleached chemical reed pulp was better than those in the waste pulp. |
