统计过程控制在包装溶剂残留量分析与监控中的应用

Research on Statistical Process Control for Solvent Residual Quantity of Packaging Materials

从质量管理的发展、我国包装企业质量管理现状及其实施统计过程控制的必要性出发,分析了-统计过程控制的意义及其控制的核心工具——控制图。在此基础上,利用均值-极差(X-R)控制图对复合过程中包装溶剂残留量进行了分析与监控。该项工作可以使现场人员及时发现相应的过程波动及缓慢变异,从而发现自身过程质量控制的不足之处。此外,该方法还为品质管理人员评定半成品、成品质量提供了客观依据。

The meaning of statistical process control and the control core tool-control charts are analyzed from theaspects of quality management development, the quality management in China＇s packaging industry and the necessity of applying statistical process control in packaging enterprises. On the basis of it, X-R control chart is used to analyze and monitor the packaging solvent residual quantity during the compound process. The on-site personnels can find the deficiencies in their own process quality control through detecting the correlative process fluctuation and the slow variation. In addition, SPC provides objective basis for quality management personnels to assess the quality of semi-products or products.
