摘要:本文研究了多种CPP(流延聚丙烯)树脂在熔融状态下的压力-体积-温度(PVT)特性。利用PVT仪测定了不同CPP树脂在不同温度和压力条件下的比容变化,采用Tait方程对实验数据进行了拟合,获得了各种CPP树脂的PVT关系参数。比较了不同CPP树脂在PVT行为上的差异,分析了分子结构、结晶度等因素对PVT特性的影响规律。研究结果对CPP树脂的加工工艺优化和薄膜产品质量控制具有重要的参考价值。
Abstract: The pressure-volume-temperature (PVT) characteristics of several cast polypropylene (CPP) resins in the molten state were investigated. The specific volume changes of different CPP resins under various temperature and pressure conditions were measured using a PVT apparatus. The Tait equation was employed to fit the experimental data.
