    摘要： The present invention relates to a polypropylene nanocomposite comprising (a) about 1 wt % to about 40 wt % of an acid- or acid anhydride-modified polypropylene; (b) about 0.1 wt % to about 50 wt % of an organically modified layered silicate; and (c) about 30 wt % to about 90 wt % of a nonpolar polypropylene, wherein the acid- or anhydride-modified polypropylene has a molecular weight that is lower than that of the nonpolar polypropylene, and wherein the polypropylene nanocomposite has a linear thermal expansion coefficient ranging from about 4×10−5/° C. to about 9×10−5/° C. The density and linear thermal expansion coefficient of these nanocomposites are, respectively, 10% to 20% and 20% to 40% less than conventional polypropylene composites and can be used to form durable molded products with superior dimensional stability, good tensile strength, good moldability, and high thermal resistance.

    摘要： An induction melting furnace having an asymmetrical sloping bottom. The melting furnace includes: an induction coil member provided on the melting furnace so as to melt waste contained in the furnace by vitrification; a bottom unit provided in a lower part of the melting furnace, the bottom unit asymmetrically sloping downward in a direction toward a glass discharge port that is formed through the bottom unit; and a cooling member integrated with the bottom unit. Due to the asymmetrical sloping bottom of the furnace, waste in the furnace can be completely melted and can be easily discharged to the outside and, accordingly, the time and cost required to treat the waste are reduced and this improves work efficiency when treating the waste. Further, due to the insulation material, the melting furnace can be protected from electric damage that may be caused by electric arc.
