Patent WO-9713629-A1 (WO)
Title: Fabrication de structures a partir de balles de riz
Inventor: LEWELLIN RICHARD LAURANCE
IPC: B27N3/00
Filed: 1996-10-04
Abstract: Cette invention concerne un procédé de fabrication de structures à partir de balles de riz non traité complet que l'on mélange à un liant thermodurcissable. On donne au mélange une forme correspondant à la forme généralement souhaitée de la structure à fabriquer en utilisant par exemple un moule ou une matrice. On élève la température à travers la forme façonnée jusqu'à ce qu'un paramètre indicateur du démarrage, ou associé au démarrage, du durcissement du liant atteigne un niveau préétabli ou soit observé. On laisse se poursuivre le durcissement du liant au-delà de ce stade, de préférence dans des conditions de processus différentes, jusqu'à ce que le liant ait presque complètement durci. On peut, pour élever la température de l'élément, appliquer un champ haute fréquence de manière à provoquer un chauffage par pertes diélectriques à l'intérieur du mélange jusqu'à ce qu'il soit possible de voir la condensation s'échapper de la structure, l'application du champ haute fréquence pouvant alors être arrêtée. Un autre procédé de chauffage qui convient à une structure poreuse consiste à créer un différentiel de pression à travers la masse et à introduire un fluide chauffé de façon à ce que ce fluide chauffé traverse la masse poreuse. On peut, afin d'obtenir une structure poreuse plus dense, comprimer la masse poreuse qui vient d'être chauffée jusqu'à ce que le durcissement du liant se produise et permette l'obtention d'une forme stable ayant la densité accrue souhaitée.
