碳酸钙目数对造纸法再造烟叶物理与烟气指标的影响.

Four kinds of film base and product were producted by adding different mesh of Calcium carbon­ate in paper-process reconstituted tobacco, whose physical and smoke indexes were tested. As the change of physical and smoke indexes of film base and product with the increase of Calcium carbonate mesh was analyzed. The results showed that physical indexes including tensile strength, burst strength, filling value and equilibrium moisture content of film base and product all presented an increasing trend except the bulk index declined. Overall, the effect of Calcium carbonate mesh on physical indexes of paper-process reconstituted tobacco was more remarkable than the film base. The smoke indexes testing results showed a higher Calcium carbonate mesh would lead to higher carbon monoxide, tar and total particulate matter in paper-process reconstituted tobacco and film base smoke, the effect of Calcium carbonate mesh on moisture, CO/tar ratio, the number of puffs and nicotine content in product smoke was smaller. In order to decrease the carbon monoxide content in product smoke, the mesh of Calcium carbonate should be smaller. The appropriate mesh was under 600 mesh. [ABSTRACT FROM AUTHOR]
