摘要
利用傅里叶变换红外光谱法对八种市售塑料袋的成分,以及它们经过不同温度条件处理后红外光谱图的改变进行了分析。通过分析得出八种市售塑料袋的主要成分均为聚乙烯,并且其主要成分在常温下不易发生变化,而在加热一段时间后某些成分会发生一定的变化。
The composition of eight saled plastic bags and their condition after treatment at different temperatures had been studied by Fourier transform infrared spectroscopy. Through analysis, the main components of eight saled plastic bags were all polyethylene, and their main components are sustained at normal temperature. However, some components had certainly changed after they were heated for a period of time.
