Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA PRODUCIR CUERPOS HUECOS DE PLASTICO, ESPUMOSOS, HECHOS DE POLIETILENO O POLIPROPILENO, EN UN PROCEDIMIENTO DE MOLDEO POR SOPLADO Y EXTRUSION, QUE UTILIZA UN EXTRUSOR DE TORNILLO SIN FIN Y UNA HERRAMIENTA DE SOPLADO. EL MATERIAL PLASTICO SE ESPUMA POR MEDIO DE UN AGENTE QUIMICO DE EXPANSION Y UN PRE-MOLDE TUBULAR COMPUESTO POR ESTE MATERIAL PLASTICO ESPUMADO SE SOPLA EN LA HERRAMIENTA DE SOPLADO. EL PROCEDIMIENTO SE CARACTERIZA POR EL HECHO DE QUE LA HERRAMIENTA DE SOPLADO TIENE UNA TEMPERATURA SUPERFICIAL DE AL MENOS 35 C, PORQUE EL AGENTE DE EXPANSION QUE SUFRE DESCOMPOSICION ENDOTERMICA CON EFECTO DE NUCLEACION SE USA EN FORMA DE UN LOTE MAESTRO A BASE DE HDPE, PORQUE EL LOTE TIENE UN TAMAÑO MEDIO DE PARTICULAS DE APROXIMADAMENTE 1 MM, Y PORQUE EL PRE-MOLDE TUBULAR SE SOPLA A UNA PRESION DE 0,5 A 2,0 BARES, O PORQUE EL PRE-MOLDE TUBULAR SE SOPLA DE ACUERDO CON UN PROCEDIMIENTO DE SOPLADO CONOCIDO COMO PROCEDIMIENTO DE SOPLADO A INTERVALOS, EN EL QUE SE PROPORCIONA UNA PRESION DE SOPLADO DE 3 A 10 BARES, Y PREFERENTEMENTE DE 8 A 10 BARES, EN UN PRIMER INTERVALO DE TIEMPO, Y SE PROPORCIONA UNA PRESION DE SOPLADO DE 0,5 A 1,0 BARES EN UN SEGUNDO INTERVALO DE TIEMPO.
