摘　　要：加热不燃烧型烟草薄片是一种新型烟草薄片,其制备方法主要包括稠浆法、辊压法、造纸法。为保证烟草薄片的良好成形及耐加工性,需添加一定量的木浆纤维。本研究探究了木浆纤维在稠浆法加热不燃烧型烟草薄片中的应用,考察了木浆纤维打浆度和添加量对稠浆性能和烟草薄片物理性能的影响。研究表明,增加木浆纤维打浆度有利于降低稠浆黏度,木浆纤维的打浆度为49°SR时,烟草薄片的力学性能相对较好;木浆纤维添加量在2%~5%时,烟草薄片力学强度随着木浆添加量的增加而增加,抗张指数最高可达3.62 N·m/g。Heat-not-burn reconstituted tobacco sheet is a new type of reconstituted tobacco sheet,and its preparation methods mainly include slurry processed,roll pressing and papermaking.A certain amount of wood pulp fiber should be added to ensure that the reconstituted tobacco sheet has good forming and processing resistance.In this study,the application of wood pulp fibers with different refining degrees in the preparation of heat-not-burn reconstituted tobacco sheet by slurry processed method was studied,and the effects of wood pulp fibers on the slurry properties and physical properties of reconstituted tobacco sheet were investigated.The results showed that increasing the refining degree of wood pulp fibers was beneficial to the decrease of thick pulp’s viscosity.When the refining degree of wood pulp fibers was 49°SR,the strength properties of heat-not-burn reconstituted tobacco sheet were relatively better.The strength properties of wood pulp increased with the increase of wood pulp content from 2%to 5%,and the highest tensile index reached 3.62 N·m/g.
