Abstract

SE PRESENTA UN MIEMBRO DE UN MOLDE DE FUNDICION HECHO DE UNA PLURALIDAD DE PARTICULAS DE ARENA UNIDAS ENTRE SI CON UN AMALGAMADOR QUE ESTA CONCENTRADO EN LOS PUNTOS DE CONTACTO ENTRE LAS PARTICULAS DE ARENA CONTIGUAS Y QUE CONSTA ESENCIALMENTE DE GELATINAS QUE TIENE UN GRADO DE BLOOM INFERIOR A ALREDEDOR 175 GRS BLOOM. LAS PARTICULAS DE ARENA SE RECUBREN PRIMERO CON UNA SUSPENSION COLOIDAL DE GELATINA, SE ENFRIAN HASTA TEMPERATURA AMBIENTE Y SE CONDICIONAN PARA UN CONTENIDO DE AGUA PRESCRITO NECESARIO PARA EFECTUAR LA MIGRACION DE LA GELATINA A LOS PUNTOS DE CONTACTO ENTRE PARTICULAS DESPUES DEL CALENTAMIENTO DE LAS PARTICULAS RECUBIERTAS EN UN MOLDE DE CONFORMACION.
