摘　　要：本文在分析了造纸法再造烟叶浆料的纤维形态及筛分情况的基础上,研究了瓜尔胶及其衍生物对造纸法再造烟叶浆料的助留助滤性能。结果表明瓜尔胶及其衍生物能够改善浆料的助留助滤性能,实验室自制的阳离子羟丙基瓜尔胶的助留助滤性能较好,当其用量为0.08%时,浆料中总细小组分首程留着率较未添加时提高了44.0%,浆料的打浆度由43°SR下降到21°SR。同时研究了瓜尔胶及其衍生物对造纸法再造烟叶基片物理性能的影响,结果表明在添加量适当时,阳离子羟丙基瓜尔胶和阳离子瓜尔胶-丙烯酰胺接枝共聚物能够在不影响基片匀度的情况下提高基片的抗张强度和松厚度。Fiber morphology and screening situation were observed and analysed in this paper. Retention and drain- age performance of adding guar gum and its derivatives on reconstituted-tobacco slurry was researched and a conclu- sion that guar gum and its derivatives improve the retention and drainage performance of the slurry was got. We also analysed the effect of guar gum and its derivatives on physical properties of papermaking reconstituted-tobacco sheet and found that guar gum and its derivatives could improve the sheet＇ s tensile strength and bulk.
