| Abstract:To reveal the effect mechanism of the distribution of calcium carbonate (CaCO3) on the comprehensive performance of cigarette paper， this study systematically investigated the key indexes such as physical strength， air permeability， and smoldering rate of cigarette paper prepared by in-pulp adding and surface spraying CaCO3， as well as the ash deposition performance and mainstream smoke component release patterns of cigarettes. The results showed that in cigarette paper prepared by surface spraying， CaCO3 was uniformly coated on the surface of fibers and filled the interstices between them， effectively improving the air permeability uniformity and thread line clarity of the cigarette paper. Compared with cigarette paper prepared by in-pulp adding， the smoldering rate was accelerated by 8.9% to 11.1%； the ash cracking rate during cigarette combustion was reduced by 7.7% to 15.6%， the width of the charred zone was narrowed， and the ash color was uniform grayish white， the tar content in mainstream smoke was reduced by 4.6% to 6.1%， and the CO release was decreased by 4.1% to 5.7%， indicating a certain effect in reducing tar and harm. |
