多層材料の構成成分を分離する方法
Document Type and Number:
Japanese Patent JP4832620
Kind Code:
B2
Abstract:
Process for separating the constituents of a multilayer material including at least one layer of a base plastic (A) and a layer of a plastic (B) which are separated by a layer of adhesive plastic (C), in which: (1) the material is heated to a temperature T1 between the crystallization temperature of the plastic B (Tc) and Tc-20 DEG C., (2) the material is next shredded by being subjected to shearing, at approximately the same temperature, so as to produce delamination and thus to convert the material into particles of small dimensions of two types, some (X) consisting essentially of base plastic (A) and others (Y) consisting essentially of plastic B and of adhesive plastic (C), and (3) the particles X and Y are subsequently separated by electrostatic separation.
