地上コイル用モールド樹脂リサイクル手法の検討

摘要

Because the number of the ground coils laid over the whole length of a maglev line is enormous, it seems that recycling becomes important in future. At first we crushed mold resin (Epoxy resin, SMC molding resin, RIM molding resin) of ground coils and confirmed the condition of the crush. Then, we mixed the crushed resin with concrete and performed an examination on its strength. As a result, we confirmed that the strength of SMC resin increased. As another examination, we dissolved resin by the depolymerization under ordinary pressure, and we confirmed the condition of the dissolution. As a result, we were able to dissolve epoxy resin. However, it has been known to us that in order to dissolve SMC resin and RIM resin, it is necessary to raise temperature and pressure because they are hard to melt.%地上コイルモールド樹脂リサイクル手法の一環として，現有地上コイルを破碎処理し，得られたモールド樹脂を骨材としたコンクリート供試体を作成し，評価試験を行った。また，常圧溶解法を用いたモールド樹脂の溶解試験を行った。その結果を以下にまとめる。
