碳酸钙颗粒形态及对PVC制品性能影响的研究

Research on the particle morphology of calcium carbonate and its influences on the properties of PVC products

通过SEM比较了不同厂家的碳酸钙颗粒形态的差异,并通过沉降体积和吸油量来表征其差异,进一步分析了轻质碳酸钙沉降体积对PVC试样力学性能的影响。

Differences in the particle morphology of calcium carbonate produced by different enterprises were compared through SEM,and the differenccs were characterized by settling volume and oil absorption.Influences of settling volumn of light calcium carbonate on the mechanical prop- erties of PVC sampleswere analyzed further.
