Verfahren zur Wiedergewinnung von Spaenen und Fasern aus Holzwerkstoffreststuecken

DE 10144793 A UPAB: 20030619 NOVELTY - The method for recovering chips and fibers of wood materials with urethane-formaldehyde or other bonding agents amenable to hydrolysis involves loading of such materials into a disintegration vessel, initial passing of steam through the vessel, soaking of the materials with a heated impregnation solution, removal of the surplus impregnation solution, and final passing of steam through the vessel. USE - For recovery of chips and fibers of wood materials bonded by means of agents amenable to hydrolysis. ADVANTAGE - The method has a greater efficiency than known comparable procedures
