PA66干切片在包装后储存时表面发黄现象分析及对策

Analysis and Tactics to the Phenomenon of the Surface of PA66 Resin Slices Turning Yellow in the Process of Storing After Packing

通过改变干燥后的PA 66树脂在包装时的温度及包装袋内的氧含量进行分析试验,结果表明,包装时物料温度较高及包装袋内氧含量较高是导致干燥后的PA 66树脂在储存时产生表面发黄现象的主要原因,依据此提出了解决办法及预防措施。

Through changing the temperature of the dried PA 66 resin slices when packing and the oxygen content in the packs,we arrive at the conclusion that the higher temperature and higher content are the main reasons causing the surface of the dried slices to turning yellow in the process of storing after packing. And in the end,we put forward solutions and precautions.
