影响几种树脂粒料产品黄色指数测定因素的研究

Study of Factors Influencing Yellow Color Index Measure for Several Kinds of Resin Aggregates Products

通过对聚乙烯、聚丙烯树脂粒料产品黄色指数测定中色差仪预热时间、标准板校正时间间隔、样品量、样品杯杯盖和平均值测量时测量次数等因素对测定结果影响的讨论,确定了黄色指数测定实验的最佳实验条件,并且得到比较好的重复性和再现性。

Through discussing the color meter warm up time, standard board calibration interval, sample weight, specimen cup cup lid in the measure process of yellow index measure of polyethylene and polypropylene resin aggregates and the influence of measure times etc.the best experimental conditions of the yellow index determination were determined, and the good repeatability and reproducibility can be got.
