전기로에서 용융한 폐유리면의 광학적 특성

다국어 초록 (Multilingual Abstract)

Glass wool scrap(GWS) were discarded from its manufacturing, car scrapping and waste insulation materials. The melting characteristics of GWS were investigated for the possibilities of recycling the wastes. GWS were mixed with raw materials of glass wool in the electric furnace with various addition amounts. In 15 wt.% GWS added specimen reveals Fe2+/Fe3+ ratio increasing to about 5 times than the normal, and the spectral transmittance near the 1050 nm was abruptly decreased as 10 wt.% added specimen. And the Chromaticity coordinates of L(lightness) was decreased, - a(green color) was increased, and -b(blue color) was increased. It means that the Fe2+/Fe3+ ratio was increased. It was thought that the residual resin burning in GWS surface caused melting atmosphere change and made the reduction of Fe3+ to Fe2+ in molten glass.The suitable addition amount for recycling GWS with its raw material should be restricted under 5 wt.%. It is because that in the melting process, the green coloring of Fe2+ ion makes heat radiation and heat transfer through the molten glass difficult.
