纸制品中聚乙烯膜定量的不确定度评定

Evaluation of Uncertainty for Quantification of PE Film in Paper Products

依据标准要求,对纸制品中聚乙烯膜定量进行了检测,同时根据方法建立数学模型,分析测量不确定度来源,计算了标准确定度和扩展不确定度,为建立有效的质量控制方法提供了依据。

According to the demands of the standard, the quantification of the polyethylene （PE） film in paper products was tested. A mathematical model was established based on the measuring method.The uncertainty sources were analyzed, and the standard uncertainty and expanded uncertainty were calculated, which provide the basis for the effective quality control method.
