폐자동차(廢自動車) Tail Lamp의 재활용(再活用)을 위한 재질분리(材質分離) 기술개발(技術開發) = The Development of Material Separation Technique for Recycling of Waste Car Tail Lamp

국문 초록 (Abstract)

본 연구에서는 폐자동차의 재활용 향상을 위하여 전량 소각 및 매립에 의해 처리되고 있는 폐자동차 tail lamp를 해체공정에서 회수하고, 마찰하전형정전선별법을 적용하여 재질분리 연구를 수행하였다. 하전특성 연구결과 PMMA재질이 폐자동차 tail lamp의 재질분리에 효과적인 하전물질로 확인되어, PMMA재질을 사용한 cyclone 하전장치를 개발하였다. 본 연구에서 개발된 cyclone 하전장치를 이용한 마찰하전형정전선별 실험결과, 최적 실험조건에서 폐자동차 tail lamp로부터 PMMA 재질의 품위와 회수율이 각각 99.0%와 90.2%인 결과를 얻어, 폐자동차 tail lamp를 재활용 할 수 있는 재질분리 기술을 확립하였다.

다국어 초록 (Multilingual Abstract)

In this study, waste car tau lamps that usually gets incinerated or buried has been recovered during the dispose process in order to increase the recycling rate of waste cars and the material separation research was performed by applying triboelectrostatic separation method. After a series of charging characteristic test, PMMA materials was confirmed of being an effective charging material for waste car tail lamp material separation, a cyclone charger using PMMA material for continuous process was developed. In optimum test conditions using triboelectrostatic separator developed in this study, high quality PMMA material with recovery rate of 99.0% and 90.2% was achieved from the waste car tail lamp. Therefore, a material separation technology that can recycle tail lamps of waste cars has been established.
