Abstract:By the rolling method, adding thermal conductive materials (graphene and carbon fiber) to a tobacco sheet could improve the heat transfer performance of the sheet.The study improved the thermal conductivity of the dedicated tobacco sheet and the heat release of tobacco components, so as to effectively improve the utilization of the heated non-combustion tobacco sheet. The sheet was characterized by TG, Raman spectroscopy, FT-IR, SEM, and thermal diffusion coefficient measurement. The results showed that the heat-conducting material was effectively distributed in the tobacco sheet, and did not affect the sensory quality of the slice. In addition, compared with carbon fiber tobacco flakes, graphene tobacco flakes had better thermal stability and thermal conductivity and had better compatibility with plant fibers.Compared with the control sample, when the content of graphene was 5%, the residual of the sheet was the lowest, which was 47.74%.The thermal conductivity and thermal diffusivity of the sheet increased by 58.77% and the heating rate of non-combustion cigarettes based on this material increased by 22.32%. |
