Abstract：In order to investigate the relationship between the viscosity of cigarette ash and cigarette ash integrity,a method was established.First,flour was used as a stabilizer to prepare cigarette ash/flour mixed samples to solve the problem that cigarette ash is insoluble in water and cannot form a stable system.Then,the macroscopic viscosi-ty factor(MVI)of cigarette ash was determined using an optical microrheometer.The MVI,ash value,gray value,and ash-holding capacity of cigarette ash from different brands of cigarettes were determined,and the correlation between the cigarette ash MVI and cigarette ash integrity was analyzed.The results showed that the stability of the MVI curve could be greatly improved by using flour as a stabilizer to prepare cigarette ash/flour mixed samples,which met the requirement for distinguishing the viscosity differences of cigarette ash from different brands.The Logistic function could fit the MVI curve well,and the R2 value of the Logistic function was above 0.99.There was a significant positive correlation between the MVI of cigarette ash and the ash value and gray value of cigarette ash.As the MVI increased,the visual effect of the ash column deteriorated.Therefore,appropriately reducing the MVI of cigarette ash helps improve the cigarette ash integrity.
