纤维模塑包装材料力学性能指标体系的构建

目的通过介绍纸浆模塑材料现有的分类,定义一种新的造型类纤维模塑包装材料,并构建其力学性能指标体系。方法分析造型类纤维模塑包装材料需要满足的特性要求和主要用途,参照纸包装材料、缓冲包装材料及整体包装材料性能的测试标准探讨造型类纤维模塑包装材料需要检测的力学性能指标。结果从强度、刚度、弹性、可塑性、柔韧性等方面对造型类纤维模塑包装材料的性能指标进行归纳分类,建立含5项二级指标,14项三级指标的力学性能指标体系。结论构建的力学性能指标体系不仅为今后模塑包装制品的结构设计提供基础依据,同时也为国内外统一模塑包装材料的测试方法和性能评价标准提供一定的参考价值。

Construction of Mechanical Performance Index System of Fiber Molded Packaging Materials

Through the introduction of existing classification of molded pulp materials, a new kind of molded pulp packaging materials was defined, whose name was modeling fiber molded packaging material. And the index system of the mechanical properties was constructed. The characteristic requirements and the main purpose of the material to be met were analyzed, and the index system of modeling molded packaging materials was discussed. Due to lack of molded pulp packaging unified test method at home and abroad, it referred to the performance test standards of paper materials, cushioning packaging materials and overall packaging materials. It concluded the performance index of modeling molded packaging materials from the strength, stiffness, elasticity, plasticity and flexibility, in order to establish the mechanical performance index system containing 5 secondary indexes and 14 tertiary indexes. It provided the basis for the structure design of the molded packaging products in the future, and also provided certain reference value for the molded packaging materials which lack unified test method and performance evaluation standard at home and abroad.
