EFFECT OF X-RAY IRRADIATION ON THE PHYSICAL PROPERTIES OF POLYVINYL CHLORIDE
Main Article Content
Abstract
In this investigation, the MBR-1618R-BE (Hitachi, Japan) machine is used to generate X-rays. Low energy X-rays vary with energies 0.5 kGy, 1.0 kGy, 5 kGy, and 10 kGy radiation level, and time is 7.83 minutes, 15.75 minutes, 78.73 minutes, and 157.46 minutes respectively. This research investigates the effect of X-ray irradiation doses on the physico-chemical properties of PVC. PVC samples before and after irradiation are transferred in liquid form by using microwave digestion Mars 6 and then X-ray Powder Diffraction (XRD) to determine the structural morphological characteristics of PVC samples. XRD results show that the change of PVC polymer structure depends significantly on a radiation dose. At the diffraction peaks of angles 17.670 and 26.170, the count at the peak region decreases sharply at a low projection dose at 0.5 kGy and 1 kGy, and in this region, the structural change according to the projection dose takes the form of a linear superlative function. With higher energy from 1 kGy to 10 kGy, the effect on the PVC structure changes gradually. The study results show that the application of radiation in PVC destruction can be applied to reduce the decomposition time. It also results in less waste disposal to the environment.
