Abstract

The invention relates to a high-gloss black decorative glass prepared from sludge incineration ash by an all-electric melting method. The high-gloss black decorative glass comprises the following raw material components in percentage by mass: 75-79% of fly ash, 5-7% of calcium carbonate, 9-10% of sodium carbonate, 5-6% of potassium alkali, 1-1.4% of boric acid, 0.03-0.04% of porous carbon, 0.06-0.08% of semi-coke powder, 0.16-0.22% of cobaltosic oxide, 0.1-0.2% of cerium dioxide, 0.04-0.06% of neodymium oxide, 0.5-0.7% of waste zircon brick powder and 0.03-0.05% of yttrium oxide. The dedusting ash is electrostatic dedusting ash collected by incineration of filtered sludge in a municipal sewage treatment plant, and belongs to hazardous waste; the porous carbon is rich in a hierarchical pore structure of sub-nano pores (0.5-1.0 nm). According to the method, a closed-loop production mode that waste is used for treating waste is constructed, high-added-value decorative materials are produced while energy consumption is reduced, and environmental protection investment is converted into economic benefits.
