알루미늄 주조과정에서 배출되는 입자상물질의 물리·화학적 특성

Abstract

PM (Particulate Matters) was collected from a bag filter dust collector at an aluminum foundries, and its physicochemical properties were investigated using particle size analyzer and scanning electron microscopy with energy dispersive X-ray spectrometer (SEM/EDS). The median volume diameter of the particles passing through the pretreatment dust collector of the cyclone was approximately 10 ㎛. The cyclone pretreatment dust collector was shown to significantly reduce the throughput of large particles with a particle size of 100 ㎛ or more. The chemical composition of the particles showed a high Al content, and trace amounts of Mg, Si, and Zn were detected.
