采用 SEM 和 EDS 技术研究了生物质缓冲包装制品的微观组织结构。 实验结果表明:采用模压发泡工艺的生物质缓冲包装制品内部形成了泡孔结构,其形状不仅与成分配伍有关,而且和成型工艺也有密切关系,当稻草纤维含量为 10% 且成型温度为 225 ℃时,制品回弹性能达到最高值 89% ;植物纤维在制品内部形成具有良好性能的网状立体结构,该结构与制品中植物纤维、淀粉的含量无关;制品表面的白色颗粒团、横条状、黑色区域等 3 种典型形态,主要成分分别为填料、植物纤维和淀粉。

The micro structures of biomass cushion packaging products were studied using SEM and EDS technology. The experimental results showed that bubble structure is formed in biomass cushion packaging products when using molded foam molding process; the shape of the bubble structure is not only relevant to component matching, but also to molding process; when the content of straw fiber is 10% and the molding temperature is 225 ℃ , the products' rebounding rate is 89% ; plant fiber forms three-dimensional mesh structure in the products, which is irrelevant to the content of plant fiber and starch; Three typical forms exist in the surface of production, such as white particles, horizontal strip, group black areas, which have the main components of infilling, plant fiber, and starch respectively.
