Espuma filtrante de 30 ppi<\/h2>\n

El PPI indica el n\u00famero de pulgadas por pulgada. Cuanto mayor sea el valor de PPI de la placa filtrante, mayor ser\u00e1 el n\u00famero de orificios por pulgada, m\u00e1s peque\u00f1os ser\u00e1n los orificios y mejor ser\u00e1 el efecto de filtraci\u00f3n.<\/strong>
\nSi el orificio es demasiado peque\u00f1o, la aleaci\u00f3n de aluminio no superar\u00e1 el l\u00edmite de fluidez, por lo que debes elegir el modelo adecuado.<\/strong><\/p>\n

\"Espuma<\/p>\n

Espuma filtrante de 30 ppi (filtro de espuma cer\u00e1mica<\/a>) se forma mediante sinterizaci\u00f3n a alta temperatura, lo que da lugar a poros abiertos interconectados entre su superficie exterior y su interior.<\/h3>\n

Cuando el fluido atraviesa el canal microporoso, la materia en suspensi\u00f3n, las part\u00edculas coloidales y la materia org\u00e1nica macromolecular quedan retenidas en la superficie del producto, y el fluido, al atravesar el canal microporoso, genera diversos efectos f\u00edsicos y qu\u00edmicos que permiten purificar y filtrar el fluido.<\/strong><\/p>\n

La espuma de 30 ppi es importante para la calidad del aluminio fundido, lo que influye en gran medida en las propiedades de procesamiento posteriores y en la calidad del producto final.<\/h3>\n

Por lo tanto, todos los pa\u00edses del mundo conceden gran importancia a la purificaci\u00f3n del aluminio fundido.<\/strong>
\nHay muchas causas que provocan la contaminaci\u00f3n por aluminio.<\/strong>
\nDurante el proceso de fundici\u00f3n, el aluminio queda expuesto a la atm\u00f3sfera del horno en estado fundido o semifundido, lo que lo hace propenso a la oxidaci\u00f3n, reacciona f\u00e1cilmente con el vapor de agua para absorber hidr\u00f3geno y forma con facilidad diversos tipos de escoria no met\u00e1lica (as\u00ed como part\u00edculas intermet\u00e1licas gruesas, etc.).<\/strong>
\nPor otra parte, parte del material de desecho de la carga de composici\u00f3n arrastra algunas impurezas que no son de aluminio durante la circulaci\u00f3n.<\/strong>
\nDado que los residuos proceden tanto de los residuos de producci\u00f3n como de los generados en los distintos procesos de la f\u00e1brica, as\u00ed como de los residuos procedentes del exterior de la f\u00e1brica, su origen es variado, su composici\u00f3n es compleja y su calidad tambi\u00e9n es deficiente.<\/strong><\/p>\n

Estas impurezas tienden a provocar la formaci\u00f3n de burbujas e inclusiones en la plancha, lo que afecta gravemente a la pureza del metal fundido y, por consiguiente, repercute negativamente en las propiedades de procesamiento, las propiedades mec\u00e1nicas, la resistencia a la corrosi\u00f3n y la calidad est\u00e9tica del producto.<\/strong><\/p>\n

Espuma filtrante de 30 ppi (filtro de espuma cer\u00e1mica<\/a>) presenta una excelente resistencia al choque t\u00e9rmico, una gran resistencia mec\u00e1nica, una elevada porosidad y una gran superficie espec\u00edfica.<\/h3>\n

Permite filtrar y adsorber el menor n\u00famero posible de impurezas del metal fundido.<\/strong>
\nGracias a su exclusivo efecto rectificador, se evita que se produzca un flujo laminar suave y r\u00e1pido y se impide la entrada de burbujas, lo que lo hace adecuado para los distintos requisitos de refractariedad y velocidad de colada en la industria de la fundici\u00f3n.<\/strong>
\nLa espuma de 30 ppi mejora significativamente la calidad de las piezas fundidas y facilita el corte, lo que reduce el desgaste de las herramientas y los costes de fabricaci\u00f3n.<\/strong><\/p>\n
