| 中文摘要: |
| 目的 研究阳离子淀粉（CS）和阳离子聚丙烯酰胺（CPAM）与加入烷基烯酮二聚体（AKD）乳液浆料的滤水性能及对纸模制品表观平滑度的影响。方法 向废旧单面瓦楞纸板浆料中分别加入CS与AKD， CPAM与AKD来制作平板纸模试样。结果 相比于只添加AKD的浆料， 先加入CS糊化液或CPAM后再加入AKD， 浆料的滤水时间和打浆度都有不同程度的降低， 且随着CS和CPAM用量的增加， 试样的摩擦因数先减小后增加， 即试样表面平滑度先提高后降低。结论 HSCS-02 型季铵型阳离子玉米淀粉具有较好的助滤性能， 能较好地改善纸模制品的表观平滑度， 其最佳质量分数为3%；CPAM的助滤性能和对纸模制品表观平滑度的改善作用优于CS， 其最佳质量分数为0.06%。 |
| 英文摘要: |
| To study the influence of CS and CPAM on the filtering performance of pulp mixed with AKD emulsion and the apparent smoothness of molded pulp products. CS and AKD or CPAM and AKD were added to the old corrugated cardboard pulp slurry and flat molded pulp samples were prepared. Compared to slurry supplemented with AKD emulsion only, both the drainage time and beating degree decreased to some extent after the addition of AKD following CS or CPAM addition, and with the increasing dosage of CS and CPAM, the frictional coefficient decreased at first and then increased, in other words, the apparent smoothness of the samples was first improved and then decreased. The HSCS-02 quaternary ammonium cationic corn starch led to better filtering performance of the pulp, and it also improved the apparent smoothness of the molded pulp products, with an optimal addition dosage of 3%. CPAM was a better filter aid agent than CS, and it improved the apparent smoothness of the molded pulp products to a higher degree as compared to CS, with an optimal addition dosage of 0.06%. |
