CPA-矩阵法测定组合浆料中变性聚乙烯醇和淀粉醋酸酯

Application of Variation Flow Analysis in TQC of Production Process

本文研究了用CPA—矩阵法同时测定变性聚乙烯醇和淀粉醋酸酯的一种新方法。选择530、550、570、670、715和730nm 为测定波长。当聚乙烯醇和淀粉醋酸酯的含量分别为4～24μg/ml,17～123μg/ml 范围内,两者比值为1.5～15,由P 矩阵计算出两者含量与加入量接近吻合。所拟定的方法可用于测定组合浆料中变性聚乙烯醇和淀粉醋酸酯含量。

Variation flow analysis(VFA)is a particular method of variance-analysis applied inthe production processes.With this method,it can comprehensively appraise for processquality,indicating where the key procedure is,providing the guide for carrying out the nexttechnical step and encouraging the free proposal of views for the management of TQC.First,the author introduces the theoretical transfer hypothesis of variation flow.And then he chan-ges,under the short term conditions with a special method,the rarely known aspects inpractice,letting the new emerging out of the old and making VAF normalized in the appli-cation and generalized in TQC.
