| 中文摘要: |
| 以碱-尿素体系溶解棉溶解浆，以2，3-环氧丙基三甲基氯化铵（EPTMAC）为醚化剂对其改性制备了阳离子纤维素（C-Cell）。采用傅里叶红外光谱仪（FT-IR）、电荷自动滴定仪（PCD）和黏度计等对C-Cell进行表征，并与阳离子瓜尔胶（C-Guar）对比，分析C-Cell与C-Guar对烟草浆料的助留助滤性能、电化学性能以及抄造后基片物理性能的影响。结果表明，两种助剂电荷量相接近，当助剂添加量为0.10%时，C-Cell在降低烟草浆料阳离子需求量、提升助留助滤性能上优于C-Guar，此外，C-Cell的添加对基片的抗张强度、松厚度等物理性能也有一定的提升。综上所述，C-Cell可作为助留助滤剂用于造纸法再造烟叶的抄造。 |
| Abstract: |
| cotton fiber was modified by 2，3-epoxypropyltrimethylammonium chloride （EPTMAC） with Alkali-Urea system as solvent to obtain a cationic cellulose （C-Cell）. C-Cell and cationic guar gum （C-Guar） was characterized by FT-IR， PCD and rotational viscosimeter. Adding those cationic auxiliaries into the tobacco pulp to produce the tobacco sheet by it. Retention and drainage performance， electrochemical characteristics of the tobacco pulp and physical properties of the tobacco sheet were tested. It was revealed that the charge quantities of those cationic auxiliaries are approximated. Compared to C-Guar， C-Cell was better than in reducing cationic demand of tobacco pulp and improving retention and filtration performance when the addition of the cationic auxiliary was 0.10%. In addition， the addition of C-Cell also improved the physical properties of the tobacco sheet， such as tensile strength and loose thickness. In summary， C-Cell can be used as retention and drainage aid for paper-making reconstituted tobacco sheet in papermaking. |
