Abstract

PROCEDIMIENTO DE FABRICACION DE TABLEROS DE FIBRAS DE MATERIAL LIGNOCELULOSICO. EL MATERIAL LIGNOCELULOSICO CONSISTE EN UNA MADERA BLANDA DE PINO, EUCALIPTUS, CHOPO O MEZCLA DE ELLAS, QUE SE DESMENUZA Y SE SOMETE A LA ACCION DE UN DIGESTOR; EL PRODUCTO RESULTANTE SE DESCIFRA Y SE SECA. LA MEZCLA ENCOLANTE SE PREPARA CON RESINA UREA-FORMALDEHIDO, FORMALDEHIDO LIBRE, AGUA, CLORURO O SULFATO AMONICO COMO CATALIZADOR. LA FIBRA SE IMPREGNA EN EL ENCOLANTE EN UN APARATO DONDE SE AGITA AQUELLA Y SE INTRODUCE ESTE MEDIANTE PULVERIZACION. LA FIBRA IMPREGNADA EN FRIO SE SOMETE A UN PREPRENSADO Y, POR ULTIMO, SE PRENSA EN CALIENTE EN UNA PRENSA DE PLATOS. A
