The Study of Phase Compound and the Degree of Crystallinity of Recycled LDPE by X-ray Diffractometer and Optical Microscope
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 2
Abstract
In this paper we study the phase compound of semi crystalline structures of recycled LDPE (Low Density Polyethylene) by Optical Microscopy and X-ray Diffraction techniques. Measurements of optical microscopy were made using the technique of polarized light microscopy in transmission mode (POM). The micrographs taken for all recycled LDPE samples indicate the presence of additives. XRD method is non destructive nature with in-depth crystallographic analysis and for this reason XRD techniques are used in this paper to study the phase compound and to calculate the degree of crystallinity of pure and recycled LDPE. By diffractgrams analyses were identified rutile’s and calcite’s peak, as additives added in the recycled LDPE. It was analyzed the influence of additives on the degree of crystallinity.
