摘要: 为了探究烟灰黏度与卷烟包灰性能之间的关系,建立了利用光学微流变仪测定烟灰宏观黏度因子(MVI)的方法,对不同牌号卷烟烟灰MVI、包灰值、灰度值和持灰能力进行了测定,并通过相关性分析研究烟灰MVI与卷烟包灰性能之间的关系。结果表明:以面粉为稳定剂制备烟灰/面粉混合试样,可以大幅提升MVI曲线的稳定性,满足区分不同牌号卷烟烟灰黏度差异性的要求;Logistic函数能够较好地拟合MVI曲线,其R2达到0.99以上;烟灰MVI与卷烟包灰值、灰度值之间呈显著正相关关系,即随着MVI的增大,灰柱的视觉效果变差。因此,适当降低烟灰MVI,有利于改善卷烟的包灰性能。Abstract: In order to investigate the relationship between the viscosity of cigarette ash and the ash integrity of cigarette, a method was established to determine the macroscopic viscosity factor (MVI) of cigarette ash by using optical microrheometer. The MVI and ash value, gray value and ash holding capacity of different brands of cigarettes were determined, andthe relationship between cigarette ash MVI and ash integrity of cigarette was studied through correlation analysis The results show that the stability of MVI curve can be greatly improved by using flour as the stabilizer to prepare the mixed sample of soot/flour, which meets the requirement of distinguishing the viscosity difference of different brands of cigarette ash. The Logistic function can fit the MVI curve well, and its determination coefficient is above 0.99. The MVI of cigarette ash was positively correlated with ash value and gray value of cigarette pack, and the visual effect of ash column became worse with the increase of MVI. Therefore, appropriate reduction of soot MVI is beneficial to improve the ash integrity of cigarette.
