Abstract

SE PRESENTAN METODOS Y UN APARATO PARA PRODUCIR ESPUMAS DE CELDA CERRADA DE ALTA CALIDAD PARA SU USO EN APLICACIONES TALES COMO REVESTIMIENTOS, SELLAMIENTOS, RELLENOS DE UNION Y JUNTAS. EN UNA PRIMERA REALIZACION SE UTILIZA UN DISPOSITIVOS MEZCLADOR ESTATICO DE PASO SIMPLE, EN LINEA (10) QUE CONTIENE UN NUMERO MUY GRANDE DE ELEMENTOS MEZCLADORES INDIVIDUALES (12) PARA DISPERSAR HOMOGENEAMENTE UN GAS A TRAVES DE UN MATERIAL POLIMERICO LIQUIDO DE ALTA VISCOSIDAD TAL COMO UN MATERIAL BASADO EN PLASTISOL, SILICONA, BUTILO O URETANO. EN UNA SEGUNDA REALIZACION SE UTILIZA TANTO UNA MEZCLADORA DINAMICA (3A) COMO UNA MEZCLADORA ESTATICA DE PASO SIMPLE (3B) EN SERIE PARA CERRAR LA ESPUMA DE CELDA CERRADA.
