El etileno de grado polimerizaci\u00f3n sirve como mon\u00f3mero base, el hexeno-1 act\u00faa como comon\u00f3mero, y un sistema catal\u00edtico a base de titanio impulsa el crecimiento de la cadena. Desde el reactor, el material pasa por desgasificaci\u00f3n, granulaci\u00f3n y envasado antes de salir de la planta como pellets de color natural que contienen cero part\u00edculas negras y ninguna contaminaci\u00f3n extra\u00f1a.<\/p>\n<p>La arquitectura molecular es bimodal: dos picos distintos en la distribuci\u00f3n de la longitud de la cadena se integran en una sola matriz de resina. La fracci\u00f3n de alto peso molecular proporciona las propiedades mec\u00e1nicas a largo plazo que exigen las especificaciones de tuber\u00edas a presi\u00f3n: resistencia al agrietamiento por tensi\u00f3n ambiental, resistencia al crecimiento lento de grietas y resistencia a la compresi\u00f3n sostenida. La fracci\u00f3n de bajo peso molecular permite una movilidad adecuada del fundido durante la extrusi\u00f3n sin sacrificar el rendimiento estructural de la pared de la tuber\u00eda terminada. La estructura bimodal es la diferencia t\u00e9cnica definitoria entre un grado de tuber\u00eda PE100 y el HDPE de uso general.<\/p>\n<p>Un \u00edndice de fluidez de 0.29 g\/10 min con una carga de 5.0 kg sit\u00faa esta resina en el rango de alto peso molecular adecuado para la extrusi\u00f3n de tuber\u00edas a presi\u00f3n de gran di\u00e1metro. En la pr\u00e1ctica, un bajo MFR significa una mayor viscosidad del fundido durante el procesamiento, lo que ayuda a mantener la consistencia dimensional en tramos largos de tuber\u00eda de pared gruesa. La densidad de 949.8 kg\/m\u00b3 confirma el grado de cristalinidad esperado en un compuesto de HDPE con clasificaci\u00f3n de presi\u00f3n.<\/p>\n<p>Los datos de las pruebas mec\u00e1nicas reflejan el equilibrio entre rigidez y capacidad de deformaci\u00f3n que exige el servicio de tuber\u00edas enterradas. Con una resistencia a la tracci\u00f3n en el l\u00edmite el\u00e1stico de 22.9 MPa y un alargamiento a la rotura de 704%, el material puede soportar una deformaci\u00f3n significativa antes de fracturarse, un comportamiento que importa cuando la tuber\u00eda enterrada se encuentra con movimiento del suelo, levantamiento por heladas o flexi\u00f3n durante la instalaci\u00f3n. La resistencia al impacto Charpy de 32.8 kJ\/m\u00b2 indica que la resina soporta impactos repentinos sin fallo fr\u00e1gil, lo cual es relevante tanto para la manipulaci\u00f3n en campo en climas fr\u00edos como para el servicio a largo plazo bajo carga c\u00edclica.<\/p>","protected":false},"excerpt":{"rendered":"<p>TUB121N3000 es una resina de polietileno de alta densidad bimodal fabricada por PetroChina Dushanzi Petrochemical Company utilizando el proceso de suspensi\u00f3n a baja presi\u00f3n Innovene S.
