摘　　要：基于磨石机械浆的植物纤维模塑餐具热压成型分为 3个阶段 ,第一阶段合模压力挤出约 75 %水分 ,第二阶段湿坯纤维细胞壁和毛细管中的水分被蒸发 ,在第三阶段当湿坯温度接近模具温度 (1 60～ 1 80℃ )时纤维被塑化。实际生产过程中热压参数调整主要在第二阶段。本文根据热传导原理导出圆筒形植物纤维模塑餐具的热压温度时间方程 ,分析了热压参数间的关系 ,并给出应用示例。There are 3 phases in hot\|press forming for plant fiber tableware made by stone mechanic pulp. First, the model presses almost 75% water, second, the water among plant fiber cells is dried, and in the 3th phase the fiber is hardened when the wet raw material is heated near the temperature (160～180℃) of the model. During the practical production, the adjustment of hot\|press parameters is mainly in the second period. This paper deduces the hot\|press time\|equation of plant fiber tableware which is tube\|shaped based on heat transfer theory, analyses the relationship between parameters, and gives an application example.
