Design Analysis of HnB Heated Tobacco Core Material with Circumferential Heating Type
In view of the lack of understanding of the core mechanism of the design and development of heated tobacco core materials in China,circumferentially heated tobacco core products represented by BAT Glo series are selected as the research objects,by testing and analyzing indicators such as microstructure,conventional physical indicators,conventional chemical indicators,and aerosol emissions.The results show that Glo tobacco core materials are produced using the traditional papermaking process of reconstituted tobacco;The circumference of the cigarette is 1.655 mm,the weight of the cut tobacco is 0.251 g/piece,the filling density is 0.272 g/cm3,and the average content of hot water soluble substances is 40.41% ;The total sugar and reducing sugar contents of the core material are relatively low,the total alkaloid content is moderate,and the average ash content is 8.60% .Glycerol and propylene glycol are the main smoke generating agents for Glo tobacco core material,with an average total amount of 10.25% ;The temperature at which the four main thermal weight loss fronts of the tobacco core material appear is around 55,160,295 and 434 ℃,respectively.The harmful components in traditional cigarettes such as benzopyrene,phenol,crotonaldehyde,and NNK are detected in the Glo tobacco core material,but the content is much lower than that in traditional cigarettes.
