为进一步研究卷烟纸在降焦减害中的作用,制备了不同参数卷烟纸并制成卷烟,考察卷烟纸碳酸钙形态、粒径和质量分数,以及助燃剂酸根类型、助留剂质量分数、罗纹形式、罗纹深度和压纹方式8种参数对卷烟主流烟气有害成分及危害性指数(H)的影响.结果表明:①8种卷烟纸设计参数的变化对主流烟气7种有害成分释放量及H值均产生不同程度影响.②采用大粒径或液态碳酸钙或提高碳酸钙质量分数有利于降低HCN、巴豆醛和H值.③采用柠檬酸和酒石酸的卷烟纸,H值较低;卷烟纸助留剂质量分数对有害成分和H值无显著影响.④采用无罗纹卷烟纸有助于降低HCN、氨和苯酚的释放量及H值;在反压卷烟纸条件下,采用浅罗纹卷烟纸有助于降低苯酚和巴豆醛的释放量及H值;在深罗纹条件下,采用正压卷烟纸,有助于降低B[a]P和苯酚的释放量及H值.“,”To study the effects of cigarette paper on reducing tar and harmful components in mainstream cigarette smoke, the cigarette paper samples with different parameters were prepared and used in cigarette manufacturing. The influences of eight cigarette paper parameters, including morphology, particle size, and content of calcium carbonate, acid radical type in combustion promoter, retention aid content, and the pattern, depth and pressing mode of marks on the harmful components in mainstream smoke and the hazard index (H) of cigarette were measured. The results showed that: 1)The variation of the eight paper design parameters influenced the H value and the levels of seven harmful components in mainstream smoke to different extents. 2)Adopting a large size or liquid calcium carbonate or increasing calcium carbonate content were beneficial to reducing the levels of hydrogen cyanide and crotonaldehyde and the H value. 3)The H value with cigarette paper containing citric acid or tartaric acid was lower, and the retention aid content in cigarette paper had no significant effects on the harmful components and the H value. 4)Plain cigarette paper reduced the releases of hydrogen cyanide, ammonia and phenol and the H value. When the paper marks were pressed on the paper back, shallow marks decreased the releases of phenol and crotonaldehyde and the H value. When deep marks were made, the mode of pressing marks on the paper front reduced the relases of B[a]P and phenol and the H value.
