核磁谱仪测定PP粉料等规指数的主要影响因素

摘要

利用MQC-23核磁共振波谱仪测定PP均聚粉料等规指数的过程,通过一系列试验,将试验数据结果与企业标准Q/SY FH(JL)5413-2014溶剂萃取法测试数据结果进行对比,找出影响测试结果准确性的主要因素.%MQC-23 NMR spectrometer was used to detect the isotactic index of PP homopolymer powder. Compared with classic methods, several influence factors were found and its effect was evaluated.
