常见混纺产品快速定量测试方法的研究

Study on Fast Quantitative Test Method for Familiar Blended Product

混纺产品中各组分的定量测试一般采用化学溶解法,试样在溶前和溶后都需烘至恒重,标准烘干时间需8～9h,严重影响样品的测试周期。文章研究了利用卤素水分测定仪对混纺样品进行快速定量测试的实验过程,并分析了结果。研究表明:对样品进行溶前和溶后的恒重干燥,只需10～20min,可以大大缩短测试时间,结果与标准法比较无显著差异。

The quantitative test for the components in blended product usually adopts the chemical dissolution method： the sample needs drying to be constant weight before and after the dissolution for about 8-9h, which has a strong impact on the test cycle. The experimental process of fast quantitative test for blended sample using halogen water-determination meter was studied and the results were analyzed. It shows that the drying time for the constant weight is greatly shorten to be only 10-20min, and the results were not evidently different with the standard method.
