摘要

在这项研究中,不同类型的聚合物在消费后塑料与纯塑料进行了研究。采用x射线衍射(XRD)和x射线荧光(XRF)技术对高密度聚乙烯(HDPE1和HDPE2)、聚氯乙烯(PVC3和PVC4)、聚对苯二甲酸乙二醇酯(PET5和PET6)和聚丙烯(PP7和PP8)进行了比较。XRF显示了塑料废料中高分子材料的k线光谱。利用x射线衍射分析改变了商用聚合物的峰强度和结晶度。不属于结晶峰的强度可视为非晶态散射,并可作为分析样品衍射图样的模板。XRD分析有助于提供特征谱线,其强度随每种组成聚合物的类型而变化。结合使用XRD和XRF技术为商业塑料管理提供了非常有用和有效的结果。

Identification and Characterization of Different Types of Plastics Wastes Using X-Ray Diffraction and X-Ray Fluorescence Techniques
In this study, different types of polymers in postconsumer plastics with pure plastics have been studied. Highdensity polyethylene (HDPE1 and HDPE2), polyvinyl chloride (PVC3 and PVC4), polyethylene terephthalate (PET5 and PET6), and polypropylenes (PP7 and PP8) were compared using X-ray diffraction (XRD) and X-ray fluorescence (XRF) techniques. XRF has shown the spectral in K-lines of polymer materials present in plastics waste. The peak intensity and degree of crystallinity of commercial polymers are varied using XRD analysis. The intensity not attributable to the crystalline peaks may be regarded as the amorphous scattering and used as a template in analyzing the diffraction pattern of the samples. The XRD analysis helps to provide characteristic spectral lines whose intensities vary with the type of each constituent polymer. The combined usage of XRD and XRF techniques yielded very useful and effective results for a commercial plastic management.
