PARTICLE AGGLOMERATION PROCESS FOR WOOD AND CORK INDUSTRIAL SECTORS

摘要

This invention relates to a particle agglomeration process of wood and co rk which uses an agglomerating system consisting of a pre-polymer of hydroxy l terminated polybutadiene (HTPB), a di-isocyanate and possibly a catalyst i n order to obtain agglomerations of cork and/or wood particles with new char acteristics and with new particle compositions. These products are used in t he particle agglomeration industry in the wood sector (wood particles boards ), specifically in the panels and veneers sub-sector and in the cork agglome ration industry sub-sector. This process enables the industrial reprocessing of residues and sub-products of sectors of wood and cork and at the same pl ays its part towards solving environmental problems by creating a viable and profitable alternative to storage and/or burning and/or depositing in the g round, in particular for what is referred to as cork powder and 'terras' and some wood residues, in particular fibre and polishing dust.
