Abstract
METODO Y APARATO PERFECCIONADOS PARA FORMAR RAPIDAMENTE ESTRUCTURAS DE ESPUMA PLASTICA A PARTIR DE UNA LAMINA DE ESPUMA FLEXIBLE. DICHA LAMINA PASA INTERMITENTEMENTE A TRAVES DE UNA UNIDAD DE CALOR RADIANTE EN LA QUE SE CALIENTA RAPIDAMENTE POR AMBOS LADOS HASTA 130-250 GRADOS F PARA ABLANDAR LA ESPUMA. LA LAMINA DE ESPUMA ASI CALENTADA PARA INMEDIATAMENTE A TRAVES DE UN TROQUEL FORMADOR EN EL QUE SE DEFORMA PARCIALMENTE EN LA CAVIDAD DEL TROQUEL AL RETIRARSE EL AIRE DE DICHA CAVIDAD, TRAS LO QUE EL MACHO DEL TROQUEL DESCIENDE Y FORMA UNA ESTRUCTURA AL TIEMPO QUE ESTA SE ENFRIA RAPIDAMENTE POR DEBAJO DE SU TEMPERATURA DE DEFORMACION PLASTICA. CON ESTE APARATO Y ESTE METODO SE FORMAN RAPIDAMENTE, A 10-30 CICLOS POR MINUTO, ESTRUCTURAS DE ESPUMA CON ETILENO CUYO GROSOR ES 10-25 VECES EL GROSOR INICIAL DE LA LAMINA DE ESPUMA.
