摘要:采用Wiley粉碎机对烟末进行粉碎，提取不同尺寸的烟末与烟梗、针叶木浆混合采用造纸法制备再造烟叶，研究了烟末尺寸对再造烟叶质量的影响。结果表明，与混合磨浆方式相比，当添加60~120目的烟末浆时，烟草基片的各项物理性能较好，在抗张强度几乎不变的前提下，松厚度与柔软性分别提升了6.28%、23.03%。随着烟末尺寸减少，烟草基片的抗张强度逐渐提高，透气性和浆料滤水速率先提高后降低，松厚度、柔软性、单程留着率均逐渐降低。

Abstract:The tobacco scrap was breaked by Wiley mill，the breached scrap with various sizes mix with softwood pulp fibers to make reconstituted tobacco sheet，the effect of scrap size on the physical properties of reconstituted tobacco sheet was investigated. The results showed that the reconstituted tobacco sheet had better physical properties with adding 60～120 mesh tobacco scrap pulp.Compared with the pulping processes of mixing softwood pulp and tobacco scrap， the bulk and softness of the sheet increased by 6.28% and 23.03%， respectively.While the tensile strength was almost unchanged. With the reduction of particle size of pulverized tobacco scrap， the tensile strength of reconstituted tobacco sheet gradually increased， permeability if the sheet and drainage rate of the stick increased firstly then decreased， but bulk， softness and first pass retention decreased gradually. Moreover， the results of smoking test of the reconstituted tobacco prepared by new process that the woody odor and stimulation reduced， the quality was improved obviously compared with the normal reconstituted tobacco sheet．
