重组烟叶型雪茄烟纸持灰性能的研究

为了改善重组烟叶型雪茄烟纸的持灰性能,在重组烟叶型雪茄烟纸中添加具有改善重组烟叶燃烧性能和持灰性能的填料(CaCO₃、TiO₂和MgO),同时设计了以灰分颜色和阴燃速率为主要影响因素、透气度为次要影响因素的持灰能力评价标准。实验利用烟梗制取的机械浆为主要原料（加入少量木浆和麻浆）,同时添加一定量的填料(CaCO₃、TiO₂和MgO),制备了重组烟叶基片,经烟草萃取液涂布后制备重组烟叶型雪茄烟纸。通过检测雪茄烟纸的阴燃速率、透气度等指标和持灰性能发现，当TiO₂和CaCO₃的用量分别为8%和12%时,阴燃速率为129.4 s/150 mm,透气度为107.7 cm³/(min·cm²),持灰得分为88分,灰分颜色较白,持灰性能得到明显提升。

Study on the Ash Integration of Burning Cigar Wrapping Paper of Reconstituted Tobacco

In order to improve the ash integration of burning cigar wrapping paper, the fillers (CaCO₃, TiO₂ and MgO) were added into the cigar wrapping paper of reconstituted tobacco, which can improve combustion performance and ash integration of reconstituted tobacco. Meanwhile, the ash integration evaluation criterion was designed based on ash color and static combustibility rate as the primary influence factors, and air permeability as the secondary influence factor. The mechanical pulp (MP) from tobacco stem was used as the main raw material, a few amount of ligneous fibers and a certain amount of fillers (CaCO₃, TiO₂ and MgO) were added to make cigar wrapping paper of reconstituted tobacco on which tobacco extracted liquid was coated, and its relevant static combustibility rate, the air permeability and ash integration were tested. The experimental results showed that when the content of TiO₂ and CaCO₃ was 8% and 12% respectively, the ash color was whiter, static combustibility rate was 129.4 s/150 mm, the air permeability was 107.7 cm³/(min·cm²), and the score of ash integration was 88 points, ash integration improved significantly.
