Abstract
A method of removing a surface material from a resin product including: coarsely crushing the resin product having a resin substrate and the surface material formed thereon by coating or adhesive bonding, introducing the coarsely crushed product into a cylinder, and transporting the coarsely crushed product in the cylinder while bringing the product into contact with heated steam and stirring the product by a rotor having a protruding bar, to peel the surface material from the product. The heat of the heated steam and the rubbing heat by the stirring reduce the bonding strength between the surface material and the resin substrate to easily peel the surface material from the product by rubbing the product with each other. Thus, the removal of the surface material formed on a surface of a resin substrate by coating or adhesive bonding can be achieved with enhanced efficiency, environment safety and processing capacity.
