摘要
为探索影响造纸法再造烟叶CO和焦油释放量的主要因素,考察了不同涂布率与造纸法再造烟叶CO和焦油释放量的相关性,研究了烟梗与碎片比例、片基定量、外加纤维种类、填料种类以及碳酸钙用量对片基CO和焦油释放量的影响。结果表明:(1)CO释放量与涂布率呈负相关,而焦油释放量与涂布率呈正相关;(2)一定范围内,烟梗与碎片比例增加或者使用未漂白的外加纤维都会增加片基CO和焦油释放量,可能是烟梗和未漂白纤维中含有较高的木质素或者果胶;(3)增加碳酸钙用量可使单位质量片基中可燃烧的有机物质减少,降低CO和焦油释放量;(4)降低片基定量或者改善填料种类可以改变片基微观结构,降低片基CO和焦油释放量。因此,在保证产品品质和加工工艺的前提下,可综合考虑上述方法降低造纸法再造烟叶烟气中CO和焦油含量。
Correlation between coating coverage rate and CO and tar delivery in paper-making reconstituted tobacco （PRT） smoke was studied. Effects of stem to scraps ratio, grammage, fibre and filler, content of calcium carbonate on CO and tar delivery were further investigated. Results indicated that：（1）Increasing coatings coverage rate resulted in decreased CO delivery and increased tar delivery;（2） High stem to scraps ratio and unbleached fibre led to a higher CO and tar delivery, which may be due to high content of lignin and pectin in stem and unbleached fibre;（3） Adding calcium carbonate to the sheet base reduced flammable organic matter, thus resulting in lower CO and tar delivery;（4） Decreased grammage or improved filler reduced CO and tar delivery by changing microstructure of sheet base. These methods can be synthetically used to reduce CO and tar delivery in paper-making reconstituted tobacco to ensure product quality and process feasibility.
