Refrakter d\u00f6k\u00fclebilir malzemelerdeki ultra ince tozun ana i\u015flevi, doldurma \u00f6zelliklerini geli\u015ftirmek ve yap\u0131 \u00f6zelliklerini iyile\u015ftirmektir. Ayr\u0131ca d\u00f6k\u00fclebilir malzemenin ak\u0131\u015f performans\u0131 artt\u0131k\u00e7a k\u00fctle yo\u011funlu\u011fu da artacakt\u0131r.<\/p>\n

Refrakter d\u00f6k\u00fclebilir malzemelere ultra ince toz eklendikten sonra g\u00f6r\u00fcn\u00fcr g\u00f6zeneklilik azal\u0131rken mukavemet \u00f6nemli \u00f6l\u00e7\u00fcde artar. Di\u011fer y\u00fcksek s\u0131cakl\u0131k \u00f6zellikleri de buna g\u00f6re geli\u015ftirilecektir. Ultra ince tozun rol\u00fc katk\u0131lardan ayr\u0131lamaz. Yaln\u0131zca do\u011fru t\u00fcrde ultra ince toz ve katk\u0131lar\u0131 se\u00e7ip do\u011fru miktar\u0131 kullanarak maksimum rol oynayabilirler.<\/p>\n

Ultra ince tozun etki mekanizmas\u0131 karma\u015f\u0131kt\u0131r \u00e7\u00fcnk\u00fc farkl\u0131 ultra ince toz \u00e7e\u015fitleri farkl\u0131 etki mekanizmalar\u0131na sahiptir. Ancak ultra ince toz miktar\u0131 %7’yi ge\u00e7emez. E\u011fer %7’yi ge\u00e7erse bo\u015fluklar\u0131 doldurmaya fazlas\u0131yla yetecek. Geriye kalan ultra ince toz, b\u00fcy\u00fck miktarda su gerektirecek ve yo\u011fun olmayacak ancak g\u00f6zeneklerde herhangi bir de\u011fi\u015fiklik olmayacakt\u0131r. Dozaj %5’in alt\u0131nda kontrol edilirse d\u00f6k\u00fclebilirdeki bo\u015fluklar doldurulacak, su t\u00fcketimi fazla olacak, hacim yo\u011funlu\u011fu k\u00fc\u00e7\u00fck olacak ve g\u00f6r\u00fcn\u00fcr g\u00f6zenekler y\u00fcksek olacakt\u0131r. Bu nedenle en iyi kullan\u0131m aral\u0131\u011f\u0131 %5-7 aras\u0131d\u0131r.<\/p>\n

Asl\u0131nda ultra ince tozun i\u015flevi doldurmakt\u0131r. Geleneksel refrakter d\u00f6k\u00fclebilir malzemelerin k\u00fctle yo\u011funlu\u011fu nispeten b\u00fcy\u00fckt\u00fcr ve bir\u00e7ok g\u00f6zenek fazla su ile doldurulacakt\u0131r. Suyu \u00e7\u0131kar\u0131ld\u0131ktan sonra g\u00f6zenekler kalacakt\u0131r. Ultra ince toz eklendi\u011finde g\u00f6zenekler ultra ince tozla doldurulacakt\u0131r. Doldurma, \u00e7ok az miktarda mikro g\u00f6zeneklerin su ile doldurulmas\u0131d\u0131r. Bu sayede refrakter d\u00f6k\u00fclebilir malzeme kar\u0131\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda su miktar\u0131 azalt\u0131lm\u0131\u015f olur. Kal\u0131plama ve kal\u0131ptan \u00e7\u0131karma i\u015fleminden sonra su bo\u015falt\u0131lacak ve kalan g\u00f6zenekler \u00e7ok daha az olacakt\u0131r. Ba\u015fka bir deyi\u015fle, ultra ince tozun eklenmesi, eklenen su miktar\u0131n\u0131 azaltacak, d\u00f6k\u00fclebilir malzemenin y\u0131\u011f\u0131n yo\u011funlu\u011funu art\u0131racak ve g\u00f6zeneklili\u011fi azaltacakt\u0131r.<\/p>\n

K\u0131sacas\u0131 refrakter d\u00f6k\u00fclebilir malzemelerde ultra ince tozun doldurma etkisi silika tozundan daha iyidir ve dozaj\u0131 da daha azd\u0131r. a-Al2O3 ultra ince tozunun par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m aktivitesi Sio2<\/a>‘ninkinden daha iyidir, \u00e7\u00fcnk\u00fc 1 \u03bcm’den k\u00fc\u00e7\u00fck ultra ince tozun oran\u0131 %96,5’i olu\u015ftururken aktif Sio2 yaln\u0131zca %69’dur.
