Abstract

EL TUBO DE PLASTICO MUESTRA UNA CAPA DE PARED EXTERNA (1) UNA CAPA INTERMEDIA (2) Y UNA CAPA DE PARED INTERIOR (3). LA CAPA DE PARED EXTERNA (1) Y LA CAPA DE PARED INTERIOR (3) CONTIENEN POLIPROPILENO O POLIETILENO. LA CAPA INTERMEDIA (2) CONTIENE DOS FASES. UNA FASE ES POLIETILENO Y LA OTRA FASE POLIPROPILENO REVALORIZADO Y ROBUSTECIDO CON FIBRAS MOLIDAS LONGITUDINALES DE VIDRIO. LA FASE DE POLIETILENO DE LA CAPA INTERMEDIA PERMITE LA UNION ENTRE LA CAPA INTERMEDIA (2) Y LA CAPA EXTERNA DE PARED (1) O BIEN CON LA CAPA DE PARED INTERIOR (3). POR LA SELECCION PROPORCIONADA DE LA FASE DE POLIPROPILENO ENRIQUECIDA CON EL ENDURECIMIENTO DE FIBRAS DE VIDRIO. SE PUEDEN DETERMINAR PROPIEDADES DEL TUBO DE VARIAS CAPAS COMO SU ELASTICIDAD. DE ESTA FORMA SE PUEDE REUTILIZAR MATERIAL DE DESECHO Y PUEDE UTILIZARSE EL TUBO DE PLASTICO DE VARIAS CAPAS POR DETERMINAR AUN LAS PROPIEDADES TECNICAS.
