摘要
以发烟物料中常见液体(甘油、水、甘油-水混合液)作为测试液,基于接触角法对加热卷烟纸防渗透能力进行评价,考查透气度、表面处理对加热卷烟纸防渗透能力的影响,并探究该方法作为加热卷烟纸耐脂度测试替代方法的可行性。结果表明:随着加热卷烟纸透气度的增加,3种测试液的接触角呈下降趋势,加热卷烟纸防渗透能力下降;不同测试液的接触角均随着改性淀粉涂覆量的增加而增大,且甘油的接触角大于水、甘油-水混合液(质量比1∶1)的接触角,接触角法能够区分不同防渗透能力的加热卷烟纸样品;丙二醇与Kit3测试液、丙二醇-乙醇混合液(质量比10∶4)与Kit5测试液在加热卷烟纸表面的接触角检测结果无显著差异,选择丙二醇或特定比例丙二醇-乙醇混合液作为测试液进行接触角测试,可以替代传统耐脂度测试方法定量评估加热卷烟纸的防渗透能力。
This study preliminarily investigated the evaluation method for the impermeability of heated tobacco paper(abbreviated as heated tobacco paper)based on the static contact angle of the common liquid in heated tobacco(glycerin,water,a mixture of glycerol and water),investigated the influence of air permeability and surface treatment on the impermeability of heated tobacco paper,and explored the feasible method to replace the traditional grease resistance determination of heated cigarette paper.These results showed that with the increase of the air permeability of the heated tobacco paper,the three liquid contact angles showed a decreasing trend which meant the impermeability of heated tobacco paper decreased;the contact angles of different liquid increased with the increase of SK3 coating amount,and the contact angle of glycerol was higher than that of water and glycerol water mixture(mass ratio=1∶1),which meant the method of contact angle could distinguish the heated tobacco paper with different impermeability;there was no significant difference between propylene glycol and Kit No.3,propylene glycol ethanol mixture(mass ratio=10∶4)and Kit No.5 solution in the contact angle results,and it was feasible to quantitatively evaluate the penetration resistance of heated tobacco paper by the contact angle method and replace the traditional grease resistance method with the contact angle of an appropriate test solution by choosing propylene glycol or a specific proportion of propylene glycol ethanol mixture.
