Abstract:
Reconstituted tobacco paper-base, with different dosage of citric acid potassium were characterized by thermogravimetry (TG), derivative thermogravimetry (DTG) and differential scanning calorimetry (DSC) thermal analysis technology. The result showed potassium dosage increased from 0.5% to 2.5%. The initial weight loss temperature of reconstituted tobacco paper-baseas and reconstituted tobacco paper-base temperature with maximum weight loss decreased gradually, when potassium dosage was 2.5%,. The above two temperatures of reconstituted tobacco paper-base respectively decreased from 290.1 ℃, 346.3 ℃to 262.4 ℃, 328.2 ℃, respectively. At the same time, the curves of DSC showed that addition of suitable amount of potassium caused partial release of the quantity of heat of the reconstituted tobacco paper-base and reduce the burning temperature.
