Abstract

정수처리 방식에 있어서 소형화의 필요성이 증대됨에 따라 복합적인 기능을 갖는 단일구조 여과재 개발이 절실히 요구되고 있다. 본 연구에서는 단일구조를 가지는 필터개발을 위하여 활성탄과 고분자 바인더로 구성된 성형체를 압출소결방식으로 제조하여, 제조된 성형체의 밀도, 공극률 및 유량을 평가하여, 최대유량을 가지는 성형체의 최적 압출 온도를 결정하였다. 또한 성형체의 공극률 평가에 있어서 전체 공극률뿐만 아니라 관통형 기공의 공극률을 추가로 평가하여 유량과의 상관성을 평가하였다. 압출온도가 고분자 바인더의 Melting point인 133 ℃ 이상인 140~230 ℃에서 단일구조 복합 활성탄 성형체 구성이 가능하였으며, 압출온도 170 ℃가 복합성형체의 밀도가 낮고, 관통기공의 공극률이 높아, 최대유량을 가지는 복합성형체의 제조가 가능한 최적 압출온도로 확인되었다. 또한 복합성형체를 통해 흐르는_x000D_ 물의 유량은 성형체의 전체 공극률 보다 관통형기공의 공극률에 크게 의존함을 알 수 있었다.

As the need for miniaturization in water purification filter increases, the development of filter media for single filtration with multiple function was strongly required. In this study, the molded activated carbon composed of single unit was manufactured by extrusion-sintering process, and then the flow rate, density and porosity were investigated using the molded activated carbon manufactured at various extrusion temperature. We confirmed that it was possible to manufacture the single unit-molded activated carbon when the extrusion temperature was 140~230 ℃ more than 133 ℃_x000D_ being of polymer binder melting point, and the optimal extrusion temperature for the molded activated carbon with maximum flow rate was 170 ℃ since the molded activated carbon had low density and high through porosity. Also we confirmed that the flow rate through the molded activated carbon was strongly dependent upon through pore porosity compared to total porosity for the molded activated carbon.
