| description | The present invention addresses a problem with conventional techniques for recycling electrical equipment that have a hardened epoxy resin and electroconductive material where a catalyst is degraded to an extent that it can no longer be reused when water is present in a dissolving system. Moisture, when present in the dissolving system for treating electrical equipment including electroconductive material of aluminum, may react with aluminum to produce an aluminate compound which is transformed into aluminum oxide (alumina) under heating, which, in turn, may cause abnormal temperature rise to melt aluminum. This may be accompanied by formation of hydrogen which can cause danger of explosion. The present invention manages moisture content in a dissolving system by drying an object to be treated with a catalyst and a solvent prior to the dissolving treatment. |
