초록

폐 LCD유리를 대상으로 발포유리제조용의 원료로 적용가능성 여부를 타진하기 위해서 폐 LCD유리의 물리화학적 특성을 조사하였다. 이를 위해서 폐 LCD유리의 화학적 성분분석, 시차열분석, 고온에서 점도 조사를 통한 유변학적 검토, 열팽창계수 등을 조사하였으며, 아울러 괴상 형태와 구상 형태의 발포체 제조 실험도 시도하였다. 모든 검토 결과 폐 LCD유리는 발포유리의 제조 원료로서 충분히 사용 가능하며, 발포화 공정은 폐 LCD유리의 효과적인 재활용방안이 될 수 있음을 보여주었다.

Physical and chemical properties of waste LCD glass were investigated to test the feasibility of feed materials for the production of foamed glass. For this study, chemical analysis, thermal analysis, rheological consideration with the viscosity change under high temperature and thermal expansion coefficient were carried out and the trial production of foamed glass as; in spherical and block type also attempted. All results showed waste LCD glass would be a good feed material for the production of foamed glass and foaming technology of LCD glass would be an effective recycling alternative.
