Abstract

Un proceso para la producción de materiales lignocelulósicos de una sola capa o múltiples capas que consisten en una capa núcleo (CL) y, opcionalmente, otras capas (OL), en donde el tiempo de gelificación a 60ºC (GT₆₀) de la mezcla de los componentes A, B, C y, opcionalmente, D, E y F que se usa para la producción de la mezcla para la capa núcleo es de 10 a 450 segundos, y en donde se mantienen condiciones especificas en la etapa (IV).A process for the production of single or multi-layer lignocellulosic materials consisting of a core layer (CL) and, optionally, other layers (OL), wherein the gel time at 60ºC (GT₆₀) of the mixture of the components A, B, C and, optionally, D, E and F that is used for the production of the mixture for the core layer is from 10 to 450 seconds, and in which specific conditions are maintained in step (IV).
