涂布工艺是造纸法烟草薄片加工过程中的核心技术之一。通过添加流变助剂CMC、GG-50、CGG于涂料中，调整涂料性质，改善涂布工艺，分析流变助剂添加与涂布加工后薄片性质之间的关系。研究表明：，随着流变助剂添加量的增大，涂料的黏度增高，涂布后烟草薄片的松厚度、透气度和填充值降低，而抗张强度和撕裂指数提高，主流烟气中焦油、总粒相物和一氧化碳的释放量增高。涂布后薄片的SEM分析表明：，当3种流变助剂的用量均为0.1%时，薄片表面呈现较好的涂层结构，涂料均匀填充于薄片纸基内部，且涂层表面没有片状结构生成。

The coating process is one of the core technologies forin the manufacture of reconstituted tobacco. In the investigation, three rheological additives, namely CMC, GG-50 and CGG, were respectively added into the coating to adjust the coating properties and improve the coating process. Then, the relationship between the additives and the properties of the reconstituted tobacco after coating is discussed. The results show that (1) with the increase of the rheological additive dosage, the coating viscosity and the tensile strength and the tear index of the reconstituted tobacco after coating increase while the bulk, the air permeability and the filling value of the reconstituted tobacco after coating decrease; (2), simultaneously, the release amounts of tar, total particulate matter and carbon monoxide in the main smoke also rise. The SEM analysis of reconstituted tobacco shows that when all the dosages of the three rheological additives are all 0.1%, the coating structure on the reconstituted tobacco surface is better, , the coating fills in the inside of reconstituted tobacco base-paper, and there is no fragment on the coating surface.
