Metal d\u00f6k\u00fcm\u00fcne y\u00f6nelik seramik k\u00f6p\u00fck filtreler, al\u00fcminyum eriyikindeki kal\u0131nt\u0131lar\u0131 giderebilir. Al\u00fcminyum \u00fcr\u00fcnlerine y\u00f6nelik kalite gereksinimleri artt\u0131k\u00e7a, filtreleme kalitesine ili\u015fkin beklentiler de giderek y\u00fckseliyor. Kal\u0131nt\u0131lar genellikle eriyikte \u00fc\u00e7 \u015fekilde bulunur: metal oksitler; refrakter par\u00e7alar\u0131 gibi yabanc\u0131 maddeler; eriyik i\u015fleme s\u00fcrecinde eriyik i\u00e7ine kar\u0131\u015fan par\u00e7ac\u0131klar.<\/p>\n
Genel olarak, eriyik i\u00e7inde as\u0131l\u0131 bulunan par\u00e7ac\u0131klar\u0131 uzakla\u015ft\u0131rmak i\u00e7in \u00fc\u00e7 y\u00f6ntem vard\u0131r: \u00e7\u00f6kelme (par\u00e7ac\u0131klar\u0131n eriyik taban\u0131nda birikmesi); y\u00fczd\u00fcrme (kal\u0131nt\u0131lar\u0131n eriyik y\u00fczeyinde y\u00fczmesi); ve s\u00fczme (par\u00e7ac\u0131klar\u0131n g\u00f6zenekli bir ortam arac\u0131l\u0131\u011f\u0131yla eriyikten ayr\u0131lmas\u0131).<\/p>\n
Par\u00e7ac\u0131k yo\u011funlu\u011fu ve \u00e7ap\u0131 y\u00fcksek oldu\u011funda genellikle do\u011fal \u00e7\u00f6kelme meydana gelir; 90 pm\u2019den daha k\u00fc\u00e7\u00fck par\u00e7ac\u0131klar\u0131n statik \u00e7\u00f6kelmesi ise pek etkili de\u011fildir. Geleneksel gazla hidrojen giderme veya ak\u0131 i\u015fleme s\u00fcrecinde olu\u015fan kabarc\u0131klar veya erimi\u015f ak\u0131, kaps\u00fcl partik\u00fcllerinin eriyik y\u00fczeyine \u00e7\u0131kmas\u0131na neden olur. \u00c7o\u011fu durumda, bu mekanizma 30um \u00fczerindeki kaps\u00fclleri etkili bir \u015fekilde giderebilir. Filtrasyon, eriyik ak\u0131\u015f\u0131n\u0131n s\u0131k\u0131 bir \u015fekilde paketlenmi\u015f k\u00fcreler, cam elyaf kuma\u015flar, metal a\u011flar, seramik k\u00f6p\u00fck filtreler veya di\u011fer g\u00f6zenekli ortamlardan ge\u00e7erek kal\u0131nt\u0131lar\u0131 eriyikten ay\u0131rma i\u015flemini ifade eder. Seramik k\u00f6p\u00fck filtrenin avantaj\u0131, \u00e7ap\u0131 ge\u00e7i\u015f deli\u011finden \u00e7ok daha k\u00fc\u00e7\u00fck olan kal\u0131nt\u0131 par\u00e7ac\u0131klar\u0131n\u0131 da giderebilmesidir.<\/p>\n
