摘要
综述了聚偏氟乙烯树脂的性能、其熔体的流变特性及在熔融加工领域的广泛应用,详细介绍了剪切变稀的非牛顿流体流变行为及其影响因素。通过分子链支化、共混和共聚可改善PVDF熔体的流变性能,以满足不同性能制品的需求以及进一步拓宽熔融加工成型方法。
The paper reviewed the performance of poly （vinylidene fluoride） resin, the rheological properties and the applications in the field of melt processing. The non-Newtonian shear thinning rheological behavior and its influencing factors were introduced detailedly. By macromolecular chain branched, blends and copolymerization, the rheological properties of PVDF melt can be improved to meet the needs of the product with different properties and to broaden the melt processing methods.
