瓦楞纸板边压强度影响因素分析

目的分析瓦楞纸板边压强度与其基本物理参数之间的关系。方法通过试验测量不同弹性模量、泊松比的原纸所对应不同结构参数的瓦楞纸板的边压强度。结果当材料一定时,原纸的定量越大,厚度越厚;原纸的纵向弹性模量总是大于横向弹性模量;相同类型的原纸随着定量的增大,其纵横向弹性模量和剪切模量逐渐增大;面纸定量相同、芯纸定量不同的瓦楞纸板,其边压强度随芯纸定量增大而增大;芯纸定量相同、面纸定量不同的瓦楞纸板,其边压强度随面纸定量增大而增大;材质相同、楞形不同的瓦楞纸板,其边压强度由大到小依次为A型、C型、B型。结论瓦楞原纸物性参数、瓦楞纸板结构参数均对瓦楞纸板边压强度有决定性的影响。

Influence Factors of Edgewise Compression Strength of Corrugated Board

The work aims to analyze the relationship between the edgewise compression strength of corrugated board and its basic physical parameters. The edgewise compression strength of corrugated board with different structural parameters corresponding to the medium with different elasticity moduli and Poisson''s ratios was measured by tests. When a certain amount of materials were provided, the larger the quantity of the medium was, the thicker the paper was. The longitudinal modulus of elasticity was always larger than the transverse modulus of elasticity; with the increase in the quantity of the medium of the same type, its longitudinal and transverse moduli of elasticity and shear modulus gradually increased. For the corrugated board with the same quantity of core papers and a different quantity of surface paper, the edgewise compression strength would increase with the increase in the quantity of surface paper. For the corrugated boards of same materials and different shapes, their edgewise compression strengths from large to small were type A, type B and type C. The parameters, such as physical property of corrugated medium and the structure of corrugated board have decisive impacts on the edgewise compression strength of corrugated board.
