Abstract

본 연구는 내열용기의 원료 성분조성비와 입도 조건이 열충격 저항성에 미치는 영향을 고찰하였다. 내열용기 제조를 위한 원료성분으로 천연의 저급점토(이하 점토로 표기), 천연의 저급규사(이하 사질로 표기) 그리고 활석 성분을 선택하였다. 내열용기 제조를 위하여 3성분계 삼각좌표를 도식하였으며 실험결과, 우수한 열충격 저항성을 갖는 점토, 사질 및 활석 성분의 배합비는 0.42, 0.33 및 0.25의 무게비로 나타났다. 또한 입도 조건에 따른 열충격 저항성에 미치는 영향을 고찰한 결과, 70 mesh 미만의 입도 조건이 100 mesh 미만의 입도 조건에 비해 우수한 열충격 저항성을 나타내었다. 그러나 70 mesh 미만의 입도로 내열용기를 제조하는 경우, 염분이 소지내로 침투되어 배출되므로서 용기로서의 기능성을 상실하게 된다. 그러므로 용기로서의 기능성과 우수한 열충격 저항성을 동시에 고려한다면 100 mesh 미만의 입도 조건에서 점토, 사질, 및 활석 성분의 조성비는 0.42, 0.33 및 0.25의 조건이 본 실험조건에서 최적 조건임을 제시하였다.

This study was investigated effects of the thermal shock resistivity according to the variation of raw material composition ratios and particle sizes in the heat-resistant container. The raw material components were selected by the natural low-grade clay(NLC), the natural low-grade silica sand(NLS) and Talc. Triangular diagram on these three components was constructed for selection of the optimum chemical composition ratios in the heat-resistant containers. As a result of the study, the optimum blending ratio was the condition of NLS(0.42) : NLC(0.33) : Talc(0.25). And as a result of the thermal shock resistivity according to the condition of particle sizes of raw materials, the thermal shock resistivity was increased at the range of particle size under the 70 mesh than the 100 mesh. But the case of manufacturing heat-resistant container in the condition of particle sizes under 70 mesh, salt crystals in the container are permeated into the inner wall and exhausted out the outer wall. Therefore, the container can not maintain the function as a container. Considering the function as a container and the excellent thermal shock resistivity, the optimum condition for the development of the heat-resistant container was the range of particle_x000D_ sizes under 100 mesh and the blending ratio of NLS(0.42) : NLC(0.33) : Talc(0.25) in this experimental condition.
