Filtros de espuma cer\u00e1mica<\/a> Tienen la misma forma inherente que la espuma de poli\u00e9ster de c\u00e9lula abierta en la que se basan. Son muy eficientes, presentan una estructura de c\u00e9lula abierta y similar a una red, tienen una porosidad muy elevada \u2014m\u00e1s del 90%\u2014 y una superficie espec\u00edfica muy grande para retener inclusiones. El filtro de espuma cer\u00e1mica se fabrica impregnando el medio de espuma b\u00e1sico con una suspensi\u00f3n cer\u00e1mica y someti\u00e9ndolo a una cocci\u00f3n a muy alta temperatura. En este proceso, el medio de espuma b\u00e1sico se descompone, pero la estructura esquel\u00e9tica cer\u00e1mica permanece intacta. En estos filtros, el metal fundido recorre un trayecto tortuoso para eliminar inclusiones muy peque\u00f1as, que son atra\u00eddas y adsorbidas por la superficie de los poros cer\u00e1micos internos.<\/p>\n![\"Filtro](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/10\/Ceramic-Foam-Filter-for-Metal-Casting.jpg\")
<\/p>\n
Los filtros de espuma cer\u00e1mica se utilizan para filtrar metales fundidos, como el aluminio, el hierro fundido, el cobre, el acero y sus aleaciones. Estos metales en estado fundido incluyen materiales met\u00e1licos y no met\u00e1licos. Ante el aumento de la demanda de productos de aluminio de alta calidad, la filtraci\u00f3n con CFF ha demostrado ser un m\u00e9todo \u00f3ptimo para mejorar la calidad del metal. Los filtros de espuma cer\u00e1mica ofrecen un m\u00e9todo sencillo, fiable y rentable para eliminar las inclusiones. La filtraci\u00f3n con CFF es un complemento al tratamiento del metal dentro del horno, como la fundici\u00f3n y la desgasificaci\u00f3n o la filtraci\u00f3n en l\u00ednea.<\/p>\n
El filtro de espuma cer\u00e1mica cuenta con una junta en los bordes que ayuda a fijarlo en la caja del filtro y garantiza que ning\u00fan metal pase sin ser filtrado. Hay diferentes tipos de juntas disponibles: juntas de fibra y juntas expandibles. Adem\u00e1s, puedes elegir filtros de espuma cer\u00e1mica sin junta.<\/p>","protected":false},"excerpt":{"rendered":"
