摘要
通过PTA对PET产品色相的影响分析,指出PTA中杂质含量,如4-CBA、钼、铁、钴等金属离子含量对PET色相L、b值有明显影响。在实际生产中应加强控制和检验分析。
By analysis on the effects of PTA on PET product hue color, pointed out that the impurity content in PTA, such as 4-CBA, metal ion content of molybdenum, iron, cobalt has obvious effect on PET L value, b value. We should strengthen the control and detection analysis in the actual production.
