materiales cer\u00e1micos espumados<\/a> surgi\u00f3 en la d\u00e9cada de 1970 y es un material poroso con propiedades de resistencia a altas temperaturas.
\nEl tama\u00f1o de sus poros oscila entre los nan\u00f3metros y los micr\u00f3metros. Presenta un cuerpo cer\u00e1mico poroso de alta porosidad con una estructura de rejilla espacial tridimensional. La porosidad se sit\u00faa entre el 20% y el 95%. Su aspecto es similar al de la espuma templada o la porcelana. Esponja: la temperatura de uso va desde la temperatura ambiente hasta los 1600 \u2103.
\nDesde que Estados Unidos invent\u00f3, en 1978, el uso de suspensiones cer\u00e1micas como la al\u00famina y el caol\u00edn para desarrollar con \u00e9xito cer\u00e1micas de espuma destinadas a la fundici\u00f3n y la filtraci\u00f3n de aleaciones de aluminio, Gran Breta\u00f1a, Jap\u00f3n, Alemania, Suiza y otros pa\u00edses han competido en este campo de investigaci\u00f3n.
\nEl proceso de fabricaci\u00f3n de los filtros Asian Foundry Filter es cada vez m\u00e1s avanzado, y los equipos t\u00e9cnicos est\u00e1n cada vez m\u00e1s mecanizados y automatizados. En funci\u00f3n de los distintos fines de aplicaci\u00f3n, se han desarrollado diversos materiales para filtros cer\u00e1micos de espuma adecuados para diferentes fines.
\nComo el A1203, el ZrO\u2082, el SiC, el nitruro de silicio, el boruro y otras cer\u00e1micas espumadas para altas temperaturas; adem\u00e1s, en algunos casos se a\u00f1aden determinados minerales, como la mullita, el Dong Qingshi, las cenizas volantes o las cenizas de carb\u00f3n, entre otros. Estos productos se han serializado y normalizado, dando lugar a una nueva industria.<\/p>\n![\"Filtro](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2020\/07\/Asian-Foundry-Filter.jpg\")

China es uno de los principales productores de productos de aluminio, y su producci\u00f3n siempre ha sido la mayor del mundo, aunque se trata principalmente de productos de gama baja. Ante la continua expansi\u00f3n de la demanda del mercado, los productos de aluminio deben orientarse hacia la gama alta. El uso de placas filtrantes de cer\u00e1mica celular puede mejorar la calidad de los productos de aluminio y elevar su categor\u00eda para satisfacer los requisitos del mercado de gama alta. Por lo tanto, la demanda de placas filtrantes...<\/p>\n
Cabe destacar especialmente que es necesario evitar la contaminaci\u00f3n secundaria del metal fundido que pueda producirse durante el proceso de solidificaci\u00f3n y conformado una vez que el aluminio fundido sale de la caja de filtrado.
\nEn este proceso, utilice aluminio antiadherente de alta resistencia y larga duraci\u00f3n, as\u00ed como una cubeta de sinterizaci\u00f3n de cer\u00e1mica de s\u00edlice fundida con buen aislamiento t\u00e9rmico, una caja frontal, una placa de distribuci\u00f3n y una tapa t\u00e9rmica, y realice una deshumidificaci\u00f3n y limpieza oportunas para eliminar posibles fuentes de contaminaci\u00f3n.<\/p>\n
Los filtros Asian Foundry constituyen la \u00faltima etapa del proceso de purificaci\u00f3n del aluminio fundido. Son imprescindibles para garantizar la limpieza del aluminio fundido.<\/p>","protected":false},"excerpt":{"rendered":"
