一种烟草材料复合滤棒的设计

目的]分析烟草纸质滤棒和醋纤滤棒对焦油的过滤效率，并结合两者设计出一种新型的复合嘴棒，以期达到卷烟产品降焦的目的。方法]通过对成品卷烟样品、无醋纤卷烟样品和烟草纸质滤棒卷烟样品主流烟气中的焦油含量的检测，分析出2种材料对焦油的过滤效率，同时根据过滤效率和目标焦油量，设计制备出烟草材料结合醋纤复合滤棒的卷烟样品，并对其主流烟气常规6项指标进行了检测。结果]试验表明，烟草纸质滤棒对焦油的过滤效率要高于醋纤滤棒，两者的过滤效率分别为2．42％／mm和2．00％／mm，设计出的2种二元复合嘴棒卷烟样品单支焦油量，能够按照预期分别下降至11．02和10．07mg／支。结论]研究设计出的二元复合滤棒卷烟样品，有效降低了烟支主流烟气中的焦油量。

The Design of a Composite Filter Rod Used by Tobacco Material

Objective ] The filter efficiency of tobacco paper filter stick and acetate filter rod on tar was analyzed. A new type composite filter rod was designed, so as to reduce tar in ilue-cured tobacco. Method] Through detecting on tar content in mainstream smoke of tobacco sam- ple, with-out acetate tobacco sample and tobacco paper filter stick, the filter efficiency of two materials on tar were analyzed. According to fil- ter efficiency and target tar content, a tobacco sample combined with acetate composite filter stick was prepared, six indexes of mainstream smoke were determined. Result] The results showed that the filter efficiency of tobacco paper filter stick is higher than acetate filter rod, the filter efficiency are 2.42%/mm and 2.00%/mm respectively. Conclusion] The binary composite filter rod can effectively reduce tar in to- bacco mainstream smoke.
