红外光谱与热分析联用方法在塑料来料控制上的应用

Application of infrared spectrometry and thermal analysis method on incoming materials control of plastics

本文介绍了红外光谱(IR)、差示扫描量热法(DSC)、热失重法(TG)在常用塑料材料检测中的联合应用。结果表明,材料图谱数据库的建立以及材料特征图谱分析是塑料来料一致性控制的有效手段。

Some common plastic materials were measured and analysed by combination of IR spectrometry, differential scanning calorimetry（DSC） and thermo gravimetry （TG）. The results show that the establishment of materials spectrum databases and characteristic spectrum analysis are effective means of consistency control of plastic incoming materials.
