El etileno de grado polimerizaci\u00f3n sirve como materia prima principal, el 1-buteno como comon\u00f3mero y el hidr\u00f3geno como regulador del peso molecular. El producto terminado cumple con la norma de ejecuci\u00f3n Q\/SY 1494-2 y se env\u00eda como pellets de color natural, libres de part\u00edculas negras y materia extra\u00f1a.<\/p>\n<p>Las especificaciones de limpieza de pellets para DFDA-7042 se mantienen en \u226410 part\u00edculas coloreadas por kilogramo y \u22641 pellet rayado o pelo de \u00e1ngulo por kilogramo. En una l\u00ednea de pel\u00edcula soplada, las inclusiones coloreadas y el pelo de \u00e1ngel se traducen directamente en defectos de gel y rayas superficiales, defectos que requieren detener la l\u00ednea para su limpieza. Controlar la calidad de los pellets a nivel de partes por kilogramo no es una formalidad de producci\u00f3n; es lo que mantiene intacto el tiempo de actividad de un convertidor de pel\u00edcula.<\/p>\n<p>La arquitectura de comon\u00f3mero de 1-buteno en DFDA-7042 coloca ramificaciones de cadena corta a lo largo de la columna vertebral de polietileno, interrumpiendo la cristalinidad de manera controlada. El resultado es una resina que equilibra la tenacidad de la pel\u00edcula con el comportamiento de flujo de fusi\u00f3n requerido para una formaci\u00f3n estable de burbujas en configuraciones de pel\u00edcula soplada de una sola capa y multicapa.<\/p>\n<p>BASTONE obtiene DFDA-7042 de la red de producci\u00f3n de PetroChina y, como distribuidor de productos de los tres principales productores petroqu\u00edmicos de China, puede extender ese abastecimiento a m\u00faltiples or\u00edgenes de suministro cuando los compradores necesitan continuidad de grado durante el mantenimiento programado o cambios en la asignaci\u00f3n de producci\u00f3n. Cada env\u00edo lleva un Certificado de An\u00e1lisis vinculado a un lote de producci\u00f3n espec\u00edfico, brindando a los equipos de adquisici\u00f3n un rastro documental al que pueden hacer referencia si la calidad de la pel\u00edcula se desv\u00eda en etapas posteriores.<\/p>","protected":false},"excerpt":{"rendered":"<p>DFDA-7042 es una resina de polietileno lineal de baja densidad fabricada por PetroChina Lanzhou Petrochemical Company utilizando el proceso de lecho fluidizado en fase gaseosa UCC con 1-buteno como comon\u00f3mero.<\/p>\n<p>Optimizado para extrusi\u00f3n de pel\u00edcula soplada, DFDA-7042 se destina a la producci\u00f3n de pel\u00edcula para empaques y pel\u00edcula agr\u00edcola donde el rendimiento mec\u00e1nico consistente y la limpieza del pellet no son negociables.
