采用自制搅拌球磨机对甘蔗渣进行机械活化预处理,以木薯淀粉为粘合剂,碳酸氢钠、碳酸氢铵、碳酸铵复配为发泡剂,以滑石粉为填料,制备植物纤维缓冲包装材料。 以静态压缩曲线为评价指标,分别研究了机械活化时间,甘蔗渣的粒径,粘合剂、发泡剂和填料用量等因素对缓冲包装材料性能的影响,并利用扫描电镜对缓冲包装材料进行表征分析。 研究结果表明:机械活化能有效地提高甘蔗渣与粘合剂、填料等的相容性,从而有效提高了缓冲包装材料的性能。

Bagasse was mechanically activated by a self-made stirring-type ball mill. The plant fibre-based cushion packaging material was prepared by using mechanically activated bagasse as raw material, cassava starch as adhesive, sodium bicarbonate, ammonium bicarbonate and ammonium bicarbonate compounded as foaming agents and talcum powder as filler. The effects of mechanical activation time, particle size of bagasse, and dosages of adhesive, foaming agent and filler on the performance of cushion packaging material were investigated by using static compression curve as evaluation index. The structure of cushion packaging material was also characterized by scanning electron microscopy (SEM). The results showed that mechanical activation can significantly enhance the compatibility among bagasse, adhesive and filler, which effectively improve the performance of cushion packaging material.
