| Abstract:In order to further investigate the influential factors and intrinsic mechanism of adhesion phenomenon of heated tobacco product（HTP） in depth， this study analyzed the effects of sheet type （drying process， slurry process， and rolling process）， sheet moisture content， and sheet filling density on the pulling force of the cigarettes. The results showed that the sheet type had the greatest impact on the pulling force of the cigarettes. The average pulling force of HTPs prepared with drying process， slurry process， and rolling process were 9.61， 1.73， and 1.98 N， respectively. HTPs prepared with sheets made by the rolling process were the most difficult to pull out， and the degree of adhesion phenomenon was positively correlated with their 2~10 nm mesoporous content of the sheets. The higher filling density or moisture content of the sheets in the cigarettes， the greater the pulling force and the more difficult it was to pull out. The secondary coke formation of tar produced from reconstituted tobacco sheets during the heating process was one of the primary cause of adhesion phenomenon. There existed a positive correlation between the severity of adhesion phenomenon and the sheet carbonization of heated. |
