Proceso de fabricaci\u00f3n de filtros de espuma cer\u00e1mica<\/a>. Actualmente existen dos m\u00e9todos principales para determinar la porosidad.<\/p>\nUna consiste en calcular el volumen del orificio de la placa filtrante seg\u00fan la ley de Arqu\u00edmedes, es decir, inyectar agua en el vaso de precipitados mediante el tubo de rebose hasta que el agua empiece a salir por dicho tubo, y la muestra se analizar\u00e1 cuando el agua ya no salga. Todas las muestras se introducen con cuidado en el agua; a continuaci\u00f3n, el agua sale por el tubo de rebose y se mide el volumen de agua en esta parte. El volumen del agua que rebosa se resta del volumen f\u00edsico de la placa filtrante, lo que da como resultado el volumen total de los orificios de la placa filtrante.<\/p>\n
Otro m\u00e9todo consiste en determinar por separado la densidad real y la densidad aparente de la muestra de ensayo y, a continuaci\u00f3n, calcular la porosidad de la muestra seg\u00fan la siguiente f\u00f3rmula.<\/p>\n
Estos dos m\u00e9todos tienen sus propias ventajas e inconvenientes. El m\u00e9todo de funcionamiento es sencillo y pr\u00e1ctico, y la velocidad de detecci\u00f3n es r\u00e1pida, pero su punto d\u00e9bil fundamental se debe a las caracter\u00edsticas de absorci\u00f3n de agua del propio material de la placa filtrante, lo que hace que el volumen de agua descargado sea inferior al volumen real. Esto hace que los datos medidos sean demasiado bajos.<\/p>\n
Aunque el proceso de ensayo del segundo m\u00e9todo es m\u00e1s complicado, durante el mismo se descarta la influencia de la absorci\u00f3n de agua del material de la placa filtrante y los datos obtenidos son relativamente precisos.<\/p>\n

<\/p>\n
En esta norma se establece que el \u00edndice de porosidad es superior a 84%. La uniformidad de los poros se utiliza para describir la diferencia entre el n\u00famero real de poros por cada 25,4 mm de longitud en la placa filtrante y el n\u00famero de poros te\u00f3ricamente requerido.<\/p>\n
Cuanto m\u00e1s peque\u00f1o sea el espacio, mejor ser\u00e1 la calidad del producto; si el espacio es demasiado grande, la capacidad del filtro de placa para retener impurezas se ver\u00e1 reducida o la velocidad de filtraci\u00f3n del hierro fundido disminuir\u00e1, lo que no satisfar\u00e1 los requisitos de producci\u00f3n espec\u00edficos del usuario.<\/p>\n
La uniformidad del tama\u00f1o de los poros depende principalmente de la espuma utilizada en la fabricaci\u00f3n del placa filtrante de espuma cer\u00e1mica<\/a>. La uniformidad de los poros de la espuma es buena, al igual que la de la placa filtrante, por lo que la elecci\u00f3n de la espuma es extremadamente importante.<\/p>","protected":false},"excerpt":{"rendered":"Porosity is the percentage of the total volume of cavities in the ceramic foam filter plate product relative to the total volume of the filter…<\/p>","protected":false},"author":1,"featured_media":11451,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[233],"tags":[12971,12970],"class_list":["post-11450","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","tag-ceramic-filter-manufacturing","tag-ceramic-foam-filter-porosity"],"yoast_head":"\n
