Production manner of the particle board and the ligneous type board which utilizes the regenerative element from the fiberboards.

摘要

PROBLEM TO BE SOLVED: To provide a recycle technique which recovers/regenerates the elements of woody material pieces or woody material fibers from a large amount of particle boards and fiberboards generated as waste building materials and make the elements available for the manufacture of new boards and highly contributes toward environmental integrity and is useful for resource conservation.;SOLUTION: The method for regenerating the elements from the particle boards and fiberboard hydrolyzes an adhesive in the particle boards and fiberboards obtained by applying an adhesive and setting up the woody material pieces or the woody fibers as the elements by hot-pressing and separates/splits the mutual bond of the elements. In addition, the method restores the hot pressure-deformed elements to their original shape. Also the boards manufactured of the regenerated elements is provided.;COPYRIGHT: (C)2004,JPO
