摘　　要：为了降低烟气中的有害物质,减少在抽吸过程中香烟对人体的危害,选用3种水溶性高分子材料,采用浸渍与冷冻干燥技术对加热非燃烧型香烟过滤嘴棒进行了改性.在二醋酸纤维丝束过滤嘴棒上负载了不同质量浓度的海藻酸钠(SA)、聚乙烯醇(PVA)和聚乙二醇(PEG),通过对改性过滤嘴棒进行扫描电子显微镜测试,以及对抽吸阻力、CO含量、烟碱含量、总粒相物含量和焦油截留率进行测定,定量评价了过滤嘴棒的改性效果.结果表明:经PEG-2改性后的过滤嘴棒,在未显著增加抽吸阻力的同时,烟气中焦油含量降低了18.3%,总粒相物含量降低了15.62%.To reduce the harmful substances in cigarette,three kinds of water-soluble polymers were selected to modify the filter rods of heat-not-burn tobaccos by dipping and freeze-drying technology.The three polymers of sodium alginate(SA),polyvinyl alcohol(PVA)and polyethylene glycol(PEG)with different contents were loaded onto the filter rods.The modification effects of the composite filters were evaluated through SEM,suction resistance,CO content,nicotine content,total particulate matter content and tar rejection rate.The results show that the filter rods modified by PEG-2 has the best comprehensive performance with little increased suction resistance.The tar content in the flue gas of PEG-2 modified filter rods is reduced by 18.3%,and the total particulate matter content is decreased by 15.62%.
