通过实验测试,研究了不同结构多层瓦楞纸板托盘的抗弯强度、抗压强度及缓冲性能。结果表明,多层瓦楞纸板楞向平行且为纵向层合时,其抗弯强度最大,最大抗弯强度与纸板层数之间满足线性关系;单层瓦楞纸板的垂直抗压强度大于平行抗压强度且大于平面抗压强度,随着瓦楞纸板层数的增加,其垂直抗压强度及平行抗压强度增加,平面抗压强度减小;多层瓦楞纸板脚墩的垂直方向承载能力较强,缓冲性能较差,采用多层瓦楞纸板与EVA 泡沫组合型式可提高其缓冲性能,当脚墩中EVA 材料厚度占脚墩总厚度的3/5,瓦楞纸板厚度占脚墩总厚度的2/5 时,脚墩的缓冲效率与抗压强度达到最优。
This paper studies the carrying capacity and cushioning performance of multi- layer corrugated pallets with different structures to improve their cushioning performance. The bending resistance, compressive strength and cushioning performance of different structures of multi-layer corrugated pallets were analyzed by means of bending test, pressure test and compression test. The results show that multi- layer corrugated fiberboards have the maximum bending resistance when the corrugation is in parallel direction and the fiberboards are in longitudinal lamination, which is consistent with the linear relation between the maximum bending resistance and layer numbers. Vertical compressive strength of multi-layer corrugated fiberboards was greater than parallel compressive strength, which was greater than plane compressive strength, and vertical compressive strength and parallel compressive strength increased with the increase of layers, but plane compressive strength decreased. Vertical carrying capacity of foot piers was high, but their cushioning performance was unsatisfactory. Multi- layer corrugated fiberboards and EVA foam were combined to improve the cushioning performance. When the EVA foam accounted for 3/5 and the multi-layer corrugated fiberboard accounted for 2/5 of the total thickness of a foot pier, the cushioning efficiency and compressive strength of feet piers reached optimal. This paper may provide references for production of multi-layer corrugated pallets.
