Abstract

A research on material separation of EVA and PET mixture plastic waste using a triboelectrostatic separator has been carried out. It was found that PP was the best charging material to give the highest charge on the surface of EVA and PET mixture plastics with an opposite polarity. Therefore, a charger of pipe line type using PP material was manufactured for separation of EVA and PET mixture plastic waste. At optimum test conditions that used PP cyclone charger developed in this study, we could separate out PET with a glade of 98.7% and a recovery of 89.7%.

본 연구에서는 마찰하전형정전선별법을 적용하여 EVA(ethylene vinyl acetate)와 PET(polyethylene terephthalate) 혼합 폐플라스틱의 재활용을 위한 재질분리 연구를 수행하였다. 하전물질 선정을 위한 하전특성 연구결과, PP(polypropylene)재질이 EV4와 PET 폐플라스틱의 재질분리에 가장 효과적인 하전물질로 확인되어, PP재질의 pipe-type 하전장치를 개발하였다. 본 연구에서 개발된 하전장치를 이용한 재질분리 실험결과, 최적 실험조건에서 PET의 품위와 회수율이 각각 98.7%와 89.7%인 결과를 얻었다.
