摘　　要： 探讨了添加碳酸钙对再造烟叶片基物理性能、渗透性能、微观结构和烟气指标的影响。结果表明,碳酸钙用量从10%增加到50%,再造烟叶片基的抗张指数、撕裂指数逐渐下降,再造烟叶片基的松厚度和透气度略微上升。再造烟叶片基的渗透性能分析表明,碳酸钙在再造烟叶片基表面有利于产生更加多的孔隙,有利于液体从再造烟叶片基表面渗透到内部,再造烟叶片基的渗透性能和吸液性能得到改善。加填50%碳酸钙后,再造烟叶片基的焦油释放量、CO释放量和总粒相物量分别下降了24.29%,10.75%和23.25%。 Calcium carbonate was added in the base-sheet of paper-making process reconstituted tobacco, its effects on the physical properties, permeability, microstructure of base-sheet and cigarette smoke index were studied. The results showed that： 1） When the adding rate of calcium carbonate increased from 10% to 50%, the tensile index and tear index of base-sheet decreased gradually, while its bulk thickness and air permeability increased slightly. 2） The analysis of permeability of base-sheet indicated that calcium carbonate was beneficial to the formation of porous structure in the surface of base-sheet and liquid＇ s permeating from the surface into the inside of base-sheet, which was helpful to improving the permeability and liquid adsorption performance of base-sheet. 3） At calcium carbonate addition rate of 50%, the deliveries of tar, CO and TPM in mainstream smoke of cigarette manufactured of the base-sheet decreased by 24.29%, 10.75% and 23.25%, respectively.
