摘要

通过控制进料比例和碱化醚化次数，制备了不同取代度的羧甲基纤维素（CMC）。通过盐酸溶液的降解制备了不同分子量的CMC。采用正交试验方法，研究了CMC的添加量、分子量和DS对烟叶拉伸强度的影响。还研究了CMC对烟片热性能和气溶胶释放的影响。结果表明，CMC的添加量和分子量对烟叶的拉伸强度有明显影响。CMC的DS对烟叶的拉伸强度没有显著影响。CMC的加入在一定程度上提高了烟片的热稳定性，并对气溶胶中尼古丁的含量产生了一定的影响。

Controllable Synthesis of Carboxymethyl Cellulose and Its Application in Tobacco Sheets

Carboxymethyl cellulose (CMC) with different degree of substitution (DS) was prepared by controlling feed ratio and times of alkalization and etherification. CMC with different molecular weight was prepared by degradation of hydrochloric acid solution. Orthogonal experiments were designed to study the effects of addition amount, molecular weight and DS of CMC on the tensile strength of tobacco sheets. The effects of CMC on the thermal properties and aerosol release of tobacco sheets were also studied. The results showed that the addition amount and the molecular weight of CMC had obvious effect on the tensile strength of tobacco sheets. The DS of CMC had no significant effect on the tensile strength of tobacco sheets. The addition of CMC improved the thermal stability of tobacco sheets to a certain extent, and had certain influence on the content of nicotine in aerosol.
