El efecto filtrante de la placa filtrante AdTech depende del tama\u00f1o de los poros de la placa, del tama\u00f1o y el tipo de inclusiones (densidad, caracter\u00edsticas de humectaci\u00f3n) y de la velocidad a la que el aluminio l\u00edquido atraviesa la placa filtrante.<\/p>\n

Los filtros de espuma cer\u00e1mica se clasifican b\u00e1sicamente seg\u00fan el tama\u00f1o de los poros: 20 PPI, 30 PPI, 40 PPI, 50 PPI y 60 PPI. Cuanto mayor es el n\u00famero, m\u00e1s peque\u00f1a es la abertura. Sin embargo, en la pr\u00e1ctica, los cuatro tipos (20 PPI, 30 PPI y 40 PPI) pueden satisfacer las necesidades de los clientes.<\/p>\n

Con el desarrollo de la ciencia y la tecnolog\u00eda, la mejora de la pureza de las aleaciones met\u00e1licas para fundici\u00f3n y el aumento de los requisitos de rendimiento en la fundici\u00f3n, se ha empezado a utilizar un nuevo tipo de filtro de espuma cer\u00e1mica en la producci\u00f3n de fundici\u00f3n, lo que ha supuesto un gran avance en la filtraci\u00f3n del metal fundido.<\/p>\n

\"Eliminaci\u00f3n<\/p>\n

La alta calidad filtro de espuma cer\u00e1mica para fundici\u00f3n<\/a> desempe\u00f1a un papel muy importante en la mejora de la calidad de las piezas fundidas. Es capaz de filtrar eficazmente las inclusiones no met\u00e1licas del metal fundido, lo que reduce los poros de escoria, mejora las propiedades mec\u00e1nicas de las piezas fundidas, mejora el acabado superficial de las mismas y prolonga su vida \u00fatil.<\/p>\n

El filtro cer\u00e1mico de espuma AdTech utiliza espuma de poliuretano como soporte. Tras la hidr\u00f3lisis, se sumerge en un recubrimiento compuesto por polvo cer\u00e1mico, aglutinante, aditivo de sinterizaci\u00f3n, agente de suspensi\u00f3n, etc., y a continuaci\u00f3n se exprime para eliminar el exceso de recubrimiento y conseguir que este quede uniforme. Se aplica el recubrimiento sobre el esqueleto del soporte para formar un cuerpo verde, que posteriormente se seca y se cuece a alta temperatura.<\/p>\n

Ofrecemos filtros de espuma cer\u00e1mica en todos los tama\u00f1os habituales: 7\u2033, 9\u2033, 12\u2033, 15\u2033, 17\u2033, 20\u2033 y 23\u2033. Disponemos de toda la gama de porosidades, desde PPI 10 hasta PPI 60 (PPI = poros por pulgada). Tambi\u00e9n es posible fabricar filtros a medida.<\/p>\n

El filtro Foundry de 30 ppi y 40 ppi es el filtro de espuma cer\u00e1mica m\u00e1s utilizado en la industria de la fundici\u00f3n de aluminio. En la fundici\u00f3n de aluminio convencional se suelen emplear placas filtrantes cer\u00e1micas de 10 a 40 ppi. En la industria aeron\u00e1utica y en la fabricaci\u00f3n de materiales de aluminio de alta calidad se suelen emplear placas filtrantes cer\u00e1micas de 30 a 60 ppi.<\/p>","protected":false},"excerpt":{"rendered":"
