Placa filtrante de espuma cer\u00e1mica porosa de al\u00famina<\/strong><\/p>\n

Alumina Porous Ceramic Foam Filter Plate is a new type of porous ceramic material with a porosity of 80%-90% and a three-dimensional network skeleton structure and through-holes.
\nPresenta numerosas ventajas, como unas propiedades qu\u00edmicas estables, una elevada resistencia mec\u00e1nica, resistencia a altas temperaturas, buena resistencia al choque t\u00e9rmico y una gran superficie espec\u00edfica.<\/p>\n

El m\u00e9todo de impregnaci\u00f3n con espuma org\u00e1nica es, en la actualidad, el proceso m\u00e1s habitual para la preparaci\u00f3n de cer\u00e1micas porosas, ya que permite obtener una cer\u00e1mica porosa con una distribuci\u00f3n uniforme de los poros, una alta porosidad y una estructura reticular tridimensional.<\/p>\n

Alumina Porous Ceramic Foam Filter Plate uses a foam impregnation process to prepare high porosity, high strength alumina porous ceramics.
\nLos resultados de la microscop\u00eda electr\u00f3nica de barrido (SEM) muestran que el m\u00e9todo de pretratamiento de la espuma y la temperatura de cocci\u00f3n influyen en las propiedades de la cer\u00e1mica porosa.
\nSe utiliza espuma de poliuretano como esqueleto de moldeo y se lleva a cabo el proceso de pretratamiento, que consiste en el remojo en alcohol y el lavado con agua.
\nLa cer\u00e1mica porosa de al\u00famina finalmente obtenida presenta una elevada porosidad, una distribuci\u00f3n uniforme de los poros, una buena conectividad entre ellos y un di\u00e1metro de poro de entre 0,3 y 1 mm.
\nLa temperatura \u00f3ptima de cocci\u00f3n de la cer\u00e1mica es de 1600 \u00b0C; a dicha temperatura, la porosidad de la cer\u00e1mica se mantiene por encima de 67% y la resistencia a la flexi\u00f3n es de 5,6 MPa.<\/p>\n

Advantages for Alumina Porous Ceramic Foam Filter Plate<\/strong>
\nEl filtro, que se basa en el principio de adsorci\u00f3n, es capaz de eliminar eficazmente las inclusiones de gran tama\u00f1o presentes en el aluminio fundido, as\u00ed como de adsorber eficazmente las inclusiones m\u00e1s peque\u00f1as.
\nNo se desprenden fragmentos rotos, lo que reduce de forma eficaz la contaminaci\u00f3n del aluminio fundido.
\nResistencia superior al choque t\u00e9rmico; mejora la capacidad de resistencia a la erosi\u00f3n del metal fundido.
\nProducci\u00f3n con caudal autom\u00e1tico, 3 procedimientos de calibraci\u00f3n, tama\u00f1o preciso, se ajusta perfectamente al recipiente del filtro.
\nMejorar el aspecto y las prestaciones de la superficie, y purificar el aluminio fundido.<\/p>\n

\"Placa
\nInstallation and function of foam ceramic filter plates<\/strong>
\nLa eficacia de filtraci\u00f3n del filtro de espuma cer\u00e1mica<\/a> plate is closely related to its proper installation and use. At the same time, it is not possible to ignore the conventional and necessary measures taken to reduce the occurrence of inclusions in the process operations such as smelting, furnace treatment, and casting, because the filtration process is employed.
\nTambi\u00e9n es necesario evitar la recontaminaci\u00f3n del aluminio l\u00edquido limpio tras la filtraci\u00f3n.<\/p>\n

Alumina Porous Ceramic Foam Filter Plate is installed and used. In general, the following aspects need to be noted:<\/strong>
\n1. Utiliza la placa filtrante correctamente:
\nEl tama\u00f1o de la placa filtrante y el n\u00famero de orificios deben seleccionarse teniendo en cuenta el rango de caudal del tipo de fundici\u00f3n concreto, el nivel m\u00e1ximo del metal l\u00edquido durante la filtraci\u00f3n, el volumen total de filtraci\u00f3n y el grado de limpieza del aluminio l\u00edquido original.
\n2. No se puede pasar por alto el tratamiento de filtraci\u00f3n previo a la fusi\u00f3n:
\nComo la escoria habitual de los hornos de fundici\u00f3n y de mantenimiento de aluminio fundido, los hornos de limpieza y los hornos de refinado. En concreto, sigue siendo necesario un dispositivo de desgasificaci\u00f3n en l\u00ednea, ya que no solo reduce el contenido de hidr\u00f3geno de la masa fundida, sino que tambi\u00e9n elimina parte de las inclusiones no met\u00e1licas.
\n3. La placa filtrante debe ser compatible con el bloque refractario cuadrado:
\nAmbos est\u00e1n dise\u00f1ados para sellar, con el fin de evitar que el metal fluya hacia la caja de fundici\u00f3n a trav\u00e9s del hueco sin ser filtrado, y tambi\u00e9n para evitar que la placa filtrante de espuma no flote en el ba\u00f1o de aluminio debido a su peso excesivamente ligero.
\n4. Precalentar antes de usar:
\nPrecalentar para eliminar la humedad y facilitar la filtraci\u00f3n transitoria inicial. El precalentamiento puede realizarse mediante calefacci\u00f3n el\u00e9ctrica o de gas. En circunstancias normales, tarda unos 15 minutos.
\n5. Durante la filtraci\u00f3n normal, no es necesario a\u00f1adir escoria para evitar los golpes y las vibraciones en la placa filtrante. Al mismo tiempo, el canal de vertido debe llenarse con agua de aluminio para evitar preocupaciones excesivas relacionadas con el agua de aluminio.
\n6. Tras la colada, vac\u00ede el metal de la celda de flujo y de la placa filtrante. Existe un vibrador, de fabricaci\u00f3n extranjera, que se coloca sobre la placa filtrante y se agita durante un minuto para eliminar aproximadamente 75% del metal l\u00edquido restante de la placa filtrante.
\n7. Por \u00faltimo, limpia el per\u00edmetro y retira la placa filtrante una vez que se haya solidificado.<\/p>\n
