홈페이지논문 초록 (Abstract)
Due to the increase in fine dust caused by deepening air pollution, interest in the adverse effects of fine dust has increased. In this study, experiments were carried out to evaluate the properties of the fine dust adsorption-type matrix by applying the photocatalyst adsorption mechanism to the matrix. ZrO2 was used as the photocatalyst. As a test item for evaluating the properties of ZrO2 fine dust adsorption cured product, unit weight, water absorption, flowability, thermal conductivity, strength, and fine dust (PM10, PM2.5) adsorption experiments were conducted. In this study, photocatalyst ZrO2 was used as a material for the adsorption of fine dust. Experimental results of fabrication of fine dust adsorption-type matrix using photocatalyst ZrO2 are as follows. As a result of the increase of the substitution rate of ZrO2, the density and the absorption rate tended to decrease and the absorption rate increased. The fluidity test showed a tendency to decrease as the substitution rate of ZrO2 increased. As a result of the thermal conductivity measurement, as the substitution rate of ZrO2 increased, it decreased due to the increase of the porosity. As a result of fine dust measurement, as the substitution rate of ZrO2 increased, the concentration tended to decrease due to the catalytic action. Compared with previous experiments using TiO2, it was confirmed that the overall performance, such as strength and economics, was significantly reduced. There is a need for a solution.
