Used aluminum beverage cans (UBC) are able to be recycled into can body material (JIS3004) by remelting. However, in these remelting processes, such problems attributed to `paints' occur as unfavorable molten metal composition (primarily titanium) and lowering of molten metal yield. Consequently, for promoting recycling of aluminum UBC, removal of these `paints' is essential. So far, the paints have been removed by thermal method etc. Previous paper reported the development of a swell-peeling method in which paints are chemically removed, ensuring the good possibility of promoting recycling of aluminum UBC. This paper reports the details of swell-peeling mechanism.
