造纸法烟草基片外加植物纤维的优化

Optimization on adding wood fiber in reconstituted tobacco sheet by papermaking process

选取不同制浆方式的浆种和不同种类的植物纤维进行实验,考察其对造纸法烟草基片物理性能的影响,选取效果较好的外加纤维进行复配,确定外加纤维种类并对其添加量进行优化。实验结果发现:采用木素含量低的阔叶木漂白硫酸盐浆、针叶木漂白硫酸盐浆、#1木浆、#2木浆、漂白龙须草浆对改善烟草基片的物理性能和降低烟草薄片的有害物质比较有效;实验最终确定添加20%漂白硫酸盐木浆(针叶木漂白硫酸盐浆∶阔叶木漂白硫酸盐浆=1∶1),在改善烟草基片物理性能的同时显著降低了烟草薄片中的有害物质。

Pulps by different pulping process and plant fibers of different kinds were used to study the impacts on the physical properties of paper-process reconstituted tobacco. Then the kind of additional wood fiber and its adding proportion were optimized with confirmed wood pulps. The results show that it is effective to improve physical properties and lower combustion of hazardous substances of the tobacco sheet by adding pulps with lower content of lignin such as BSKP. BHKP, pulp 1, pulp 2 and the bleached binata pulp. The optimal experiment scheme was aohieved with 20% ofBKP （ BSKP ： BHKP=1 ： 1） added, which can effectively improve physical properties and lower combustion of hazardous substances of the tobacco sheet.
