摘要
从材料的发色机理及颜色与分子结构的关系角度对白色PVC－U门窗异型材的粉色现象进行了论述，进而就PVC材料发色结构的形成机理和PVC稳定体系的稳定机理进行了探讨分析，提出了解决PVC异型材粉色现象的途径和方案，并进行了试验验证。
Pinking pnenomenon about white PVC-U door and windowprofiles are discussed from the standpoint of relationship between colouring mechanism,colour and molecular structure of the materials,analysis is made then of foring mechanism of PVC coluring structure and stabilizing mechanism of PVC stabilizing system,way and alternative for solution of PVC profiles pinking are presented and stests were made for verification.
