Abstract
In this treatment method of a coated wire, a coated wire, which is a metal wire coated with a resin, is subjected to low-temperature heating in a non-combustion atmosphere in coexistence with an alkali to embrittle the coating resin, the embrittled coating resin is crushed, and the coating resin and the metal wire are separated.
Claims4
A treatment method of a coated wire, the method comprising:
- subjecting a coated wire, in which a metal wire is coated with a resin including plasticizers, to low-temperature heating in a non-combustion atmosphere in coexistence with an alkali to embrittle the coating resin,
- crushing the embrittled coating resin, and
- separating the coating resin and the metal wire, wherein
- a temperature of the low-temperature heating is 180° C. to 270° C., and
- in subjecting the coated wire to the low-temperature heating in the non-combustion atmosphere in coexistence with the alkali, the plasticizers are decomposed by the alkali.
