激光预打孔接装纸透气度与孔面积数学模型的建立

摘要

The relations between permeability and pore radius of laser perforated tipping paper in tobacco were build. Setting different rows andnumbers of pores of tipping paper to respectively test the permeability and pore area,and analyze the relationship between permeability and pore area of laser perforated tipping paper,then a mathematical model was established. Results showed that,the permeability and pore area of laser perforated tipping paper were highly correlated,the better regression equation between the pore area(S,μm2/cm)and permeability(A ,cm3/min,150
