摘要
为研究烟草薄片中碳酸钙留着性能的影响因素,本研究采用CO_(2)处理的离子色谱法测定不同工艺制备的基片中碳酸钙含量,进而分析得到碳酸钙添加比例、纤维打浆度、配浆工艺等对碳酸钙留着以及基片物理性能的作用规律。结果表明,随着碳酸钙添加比例由5%增加到20%,其留着率降幅达58.7%。同时,相比不添加碳酸钙,基片松厚度上升7.3%,而抗张指数下降13.1%。随着烟草浆中烟末浆添加比例由10%增加到90%,碳酸钙留着率下降23.1%;随着烟草浆打浆度由23°SR提升到71°SR,碳酸钙留着率增加了54.9%。随着外加纤维添加比例由0增加到20%,碳酸钙留着率提高29.5%;随着外加纤维打浆度由26°SR增加到76°SR,碳酸钙留着率先上升后下降。随着瓜尔胶添加比例由0增加到0.3%,碳酸钙留着率上升236.1%,同时基片松厚度和抗张指数分别下降5.7%和28.1%。此外,随着基片定量由48.7 g/m^(2)增加到84.4 g/m^(2),碳酸钙留着率先上后下降,基片松厚度下降36.8%,抗张指数上升46.6%。
To investigate the influencing factors on the retention performance of calcium carbonate in reconstituted tobacco sheets,this study employed CO_(2)-treated ion chromatography to measure the calcium carbonate content in base sheets produced via different papermaking processes.Subsequently,the study analyzed the effects of calcium carbonate addition ratio,fiber beating degree,pulp blending process,and other factors on calcium carbonate retention and the physical properties of the base sheets.The results showed that as the calcium carbonate addition ratio increased from 5%to 20%,its retention rate dropped by 58.7%.Meanwhile,compared to base sheets without calcium carbonate addition,the bulk rose by 7.3%,while the tensile index declined by 13.1%.As the proportion of tobacco fine pulp in the tobacco pulp blend rose from 10%to 90%,the calcium carbonate retention rate decreased by 23.1%.When the beating degree of the tobacco pulp increased from 23°SR to 71°SR,the calcium carbonate retention rate rose by 54.9%.As the addition ratio of external fibers increased from 0 to 20%,the calcium carbonate retention rate improved by 29.5%;when the beating degree of external fibers increased from 26°SR to 76°SR,the calcium carbonate retention rate first increased and then decreased.As the guar gum addition ratio increased from 0 to 0.3%,the calcium carbonate retention rate surged by 236.1%,while the bulk and tensile index of the base sheets decreased by 5.7%and 28.1%,respectively.Additionally,as the basis weight of the base sheets increased from 48.7 g/m^(2)to 84.4 g/m^(2),the calcium carbonate retention rate first rose and then declined,the bulk dropped by 36.8%,and the tensile index increased by 46.6%.
