不同梗叶比例对造纸法再造烟叶片基的影响
|
摘要
为了研究不同梗叶比例对造纸法再造烟叶的影响,分别从物理性能、化学成分、烟气成分、热性能及微观结构等方面,对不同梗叶配比下制备的再造烟叶片基进行全面系统地比较。结果表明:(1)随着梗叶比的增大,再造烟叶片基的抗张强度、透气度、松厚度及灰分均呈上升趋势;(2)再造烟叶片基随着梗类占比的上升,总氮及总植物碱含量下降,主要是由于氮元素和总植物碱主要来自于叶类物质,而梗类物质中含量较少;(3)不同梗叶比例下的再造烟叶热性能相近,相比于叶类,梗类含有较多的半纤维素;(4)随着梗类含量的逐渐上升,再造烟叶中长纤维含量占比提高,长、短纤维交接形成的孔隙结构增多,整个再造烟叶的结构向立体化方向发展。
In order to study the influence of different ratio of stem to leave on papermaking reconstituted tobacco, the physical properties, chemical composition, smoke composition, thermal properties and microstructure of reconstituted tobacco has been compared respectively. The results indicated that:(1) the tensile strength, air permeability, bulk and ash content of the reconstituted tobacco were all increased with the increase of stem ratio;(2) with the increase of stem proportion, the content of nitrogen and total alkaloid decreased, which indicated that nitrogen and total alkaloid mainly came from scarps, while stems contains little;(3) the thermal performance of reconstituted tobacco with different raw materials is similar, and stems had more hemicellulose than scraps;(4) as the proportion of stems rose, the content of long fiber increased, and pore structure created by long and short fiber interlaced form increased, the structure of the whole reconstituted tobacco turned to be three-dimensional.
