Abstract

LA INVENCION SE REFIERE A UNA CONDUCCION DE LIQUIDO DE ENFRIAMIENTO CON MOLDEO DE SOPLADO A PARTIR DE MULTIPLES CAPAS DE POLIMERO CON ALTA RESISTENCIA A PRESION DE REVENTADO E HIDROLISIS PARA MOTORES, EN PARTICULAR MOTORES DE VEHICULO. SE HA DETERMINADO, QUE LAS CONDUCCIONES ESTRATIFICADAS DE ESTE TIPO DISPONEN DE FORMA SORPRENDENTE DE UNA APLICACION ADECUADA CON UNA COMBINACION DE CAPAS ACTIVAS DE FORMA DIFERENTE CON DISTINTO ESPESOR A PARTIR DE POLIMEROS APROPIADOS, POR EJEMPLO CON UNA CAPA INERTE PARA EL MEDIO DE ENFRIAMIENTO, CON UNA CAPA INTERNA NO HINCHABLE Y UNA CAPA EXTERIOR RIGIDA, PORTADORA, RESISTENTE DE FORMA ESPECIAL A PRESION DE REVENTADO, SIENDO APROPIADAS DE FORMA ESPECIAL. ESTAS CAPAS DEBEN SER TOLERABLES UNA CON OTRA O ESTAR UNIDAS A TRAVES DE UNA CAPA INTERMEDIA TOLERABLE CON AMBAS CAPAS. LAS CONDUCCIONES DE ACUERDO CON LA INVENCION DE ESTE TIPO HAN SIDO MOLDEADAS MEDIANTE SOPLADO CON PREFERENCIA DESPUES DE COEXTRUSION DE SUS CAPAS A PARTIR DE POLIMEROS DIFERENTES Y DESPUES DE LA INCLUSION DE MATERIALES EN BRUTO DE MANGUERA FLEXIBLE O DE TUBO EN UNA FORMA CUALQUIERA, SEGUN UNA MANIPULACION CONOCIDA DE TUBERIA FLEXIBLE 3-D, DE FORMA CONOCIDA.
