La estructura resultante \u2014 CH\u2082=C(CH\u2083)-CH\u2082-O-(CH\u2082-CH\u2082-O)\u2099-H \u2014 conserva un doble enlace terminal reactivo que impulsa la copolimerizaci\u00f3n por radicales libres con \u00e1cido acr\u00edlico durante la s\u00edntesis de PCE. A temperatura ambiente, HPEG 2400 es un s\u00f3lido blanco o amarillo claro con un valor de croma Pt-Co \u226420, lo que indica un producto limpio y de bajo color adecuado para formulaciones de aditivos claros o ligeramente pigmentados.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">La retenci\u00f3n del doble enlace es la especificaci\u00f3n que m\u00e1s importa a los qu\u00edmicos de producci\u00f3n de aditivos. Con una retenci\u00f3n \u226594% y un grado de insaturaci\u00f3n \u22650.3916%, HPEG 2400 ofrece una reactividad consistente en el reactor de polimerizaci\u00f3n, reduciendo la variaci\u00f3n de rendimiento entre lotes en el PCE terminado y disminuyendo las p\u00e9rdidas por mon\u00f3mero no reaccionado. Un valor de hidroxilo de 23.3 \u00b1 1 mg KOH\/g confirma la qu\u00edmica del extremo de la cadena y la consistencia del peso molecular entre lotes de producci\u00f3n.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Los superplastificantes PCE producidos con HPEG 2400 logran tasas de reducci\u00f3n de agua del 30\u201335% en dise\u00f1os de mezclas de concreto, mejorando la trabajabilidad con relaciones agua-cemento m\u00e1s bajas mientras aceleran el desarrollo de resistencia a la compresi\u00f3n temprana. Los fabricantes de aditivos conf\u00edan en el PCE basado en HPEG 2400 en un amplio espectro de grados de concreto, desde el suministro est\u00e1ndar de premezclado hasta instalaciones de prefabricados donde la ganancia de resistencia temprana controla directamente las tasas de rotaci\u00f3n de moldes y el rendimiento de producci\u00f3n.<\/p>\n<p>BASTONE adquiere HPEG 2400 de dos fabricantes calificados \u2014 PetroChina Jilin Petrochemical (marca Kunlun) y Lianyungang Petrochemical (marca STL) \u2014 y lo ofrece junto con EPEG 3000 y TPEG 2400 como parte de una l\u00ednea completa de mon\u00f3meros de poli\u00e9ter de un solo proveedor.
