摘　　要：分析了影响塑料密度测量准确性的几种因素。从制样、取样、测量等方面进行了详细分析,探讨了注塑工艺条件及塑料含水率对塑料密度的影响,取样时尽量选取样品中部,测量时不可忽视悬丝质量等细节的影响,指出了提高密度测量准确度的正确操作方法。只有严格控制制样及测量中的各个环节,才可以保证塑料密度测量的准确性。Several factors influencing measuring accuracy of the density of plastics were analyzed. The aspects such as sample preparation, sampling, measuring were analyzed in detail. The impact of plastic injection molding process conditions and moisture content of plastics on density of plastics was discussed. Try to select the central of sampling, and the impact of cremaster quality etc. during measurement can not be ignored. The correct operation method to increase accuracy of density measurement was pointed. Only strict control each link of sample preparation and measurement, we can ensure measuring accuracy of the density of plastics.
