ペレット状の熱可塑性高分子材料の乾燥挙動解析

抄録

In this study, a rational study on the energy consumption of pre-drying process of the polymer pellets was carried out. Polyamide with pellet shape was used as the test material, and the weight change at different drying temperature was measured by a moisture analyzer. The diffusion coefficient of moisture considering the effect of temperature and moisture fraction within a pellet was derived from the obtained results, and a model for the simulation of drying process was built. Electric energy consumption for the drying process that was predicted by this model showed that there was an appropriate drying temperature that minimizes the energy consumption to achieve a prescribed drying condition.
