Abstract

SE DESCRIBE UN PROCESO Y UN DISPOSITIVO PARA LA ELABORACION CONTINUA DE ESPUMA EN BLOQUES MEDIANTE ESPUMADO DE UNA MEZCLA DE POLIURETANO REACTIVA CONTENIENDO DIOXIDO DE CARBONO DISUELTO BAJO PRESION. LA PRESION DE LA MEZCLA ES DISIPADA AL PASAR A TRAVES DE UN AREA DE EVACUACION CON PERFIL DE RANURA ANULAR. SE PREVIENE EL BLOQUEO DE LA RANURA DEBIDO A MOVIMIENTOS RELATIVOS DE LA SUPERFICIE DE LIMITACION PERIFERICA DE LA RANURA.
