ABSTRACT SOx, NOx, COx, volatile organic compounds (VOCs), and Hg vapor directly and indirectly harm the atmospheric environment and human health by contributing to the formation of photochemical smog, acid rain, and haze and posing risks of potential toxicity (, carcinogenicity). Therefore, effectively controlling and reducing the pollution caused by these chemicals is critical, and to ...
A planetary ball mill (DECOPBMV) was used to treat the fly ash. During dry milling, 10 g of fly ash and 40 g of ball were added into a 250 mL barrel of a planetary ball mill. During wet milling, in addition to the fly ash and ball, 10 mL of deionized water was added to the 250 mL barrel.
Ball mill treatment was used to reduce the size of the fly ash particles while also modifying their surface topography. The comparisons of untreated and ball mill treated fly ash filled rubber compounds and rubber compounds containing different fillers were accomplished subsequently. The results revealed that the partial addition of up to 10 ...
