摘要
通过对聚丙烯产品黄色指数测定中样品量、色差仪预热时间和标准板校正时间对测定结果影响因素的讨论,确定了黄色指数测定实验最佳实验条件。
The affecting factors that are caused by the quantity of the sample, the warm - up time duration of the chromatic instrument and the correction time duration of the standard board in the yellow index measurement of polypropylene products are discussed. As a result, the best experimental conditions for the yellow index are confirmed.
