Abstract
이를 위해 본 발명에 따른 탄성칩은 EPDM과 제강슬래그를 포함하고, 상기 제강슬래그는 아토마이징된 볼 형태이며, 상기 탄성칩의 전체 중량대비 6.08±0.15중량%을 차지한다.
따라서, 제강슬래그를 탄성칩의 부자재로 활용하여 자원의 활용도를 높이고 탄성칩의 생산 단가를 낮출 수 있으며 탄성칩의 설치 또는 사용면으로부터 중금속 등의 유해성분의 용출에 대한 염려를 덜 수 있다.
뿐만 아니라, 여과재로서의 역할을 담당하는 아토마이징된 볼형의 제강슬래그 즉, PS볼을 통해 본 발명에 따른 탄성칩이 포설된 지역의 유해물질의 흡착 또는 유기물을 제거하여 환경정화까지 기대할 수 있다.
