EDGE STABILIZED WOOD COMPOSITE PANEL

摘要

EDGE STABILIZED WOOD COMPOSITE PANEL A composite wood panel of improved edge swell characteristics is provided by applying stabilizing additive to the exposed surface of a layup of wood particles wafers from which the panel is to be formed by consolidation as the layup is being produced. The additive is applied only in selected areas one adjacent each side edge of the layup so that the resultant product has in effect stabilizing additive through the thickness of the resultant panel at each side edge. Preferably the additive will be applied as stripes at spaced depths through the layup and these stripes will extend inwardly from each side edge a distance sufficient to stabilize the panel against edge swelling. The preferred additive is an isocyanate type resin adhesive.
