Establishment of Mathematical Model for the Permeability and Pore Area of Laser Perforated Tipping Paper

研究建立卷烟激光预打孔接装纸透气度和打孔孔径关系。设置不同打孔排数、孔数的激光预打孔接装纸,分别测试其透气度和孔面积,分析透气度和孔面积的关联性,建立数学模型。结果表明,激光预打孔接装纸透气度和孔面积高度相关,单位长度孔面积(S,μm2/cm)和透气度(A,cm3/min,150<A≤800)的较优回归方程为S=547.3A+37 813.6(r=0.985,P<0.000 1),利用所建数学模型计算打孔孔径,与实测值的偏差均小于1%。

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<A≤800) per unit length was S=547.3 A+37 813.6(r=0.985,P<0.0001).Calculating pore radius with the model,the deviations between measured value and calculated value were less than 1%.
