K\u00f6p\u00fck Seramik Filtreleme Mekanizmas\u0131<\/h2>\n

1. Ataletli filtreleme ve tutma, s\u00fcrt\u00fcnme, \u00e7\u00f6kme ve di\u011fer mekanik filtreleme y\u00f6ntemleri sayesinde, filtreleme verimlili\u011fi, filenin g\u00f6z aral\u0131\u011f\u0131yla do\u011fru orant\u0131l\u0131d\u0131r. seramik k\u00f6p\u00fck filtre<\/a>.

2. Erimi\u015f maddenin i\u00e7ine partik\u00fcllerin birikmesi ve \u0131zgara destek duvarlar\u0131n\u0131n d\u00fczensiz yap\u0131s\u0131 sayesinde, heterojen partik\u00fcllerin tutma kabiliyeti art\u0131r\u0131lm\u0131\u015ft\u0131r.<\/p>\n

3. \u0130skele y\u00fczeyindeki bo\u015fluktan kaynaklanan p\u00fcr\u00fczl\u00fc y\u00fczey, s\u0131v\u0131 al\u00fcminyum ak\u0131\u015f\u0131 ile seramik kat\u0131 y\u00fczey aras\u0131ndaki aray\u00fcz\u00fc art\u0131r\u0131r; bu da s\u0131v\u0131 al\u00fcminyum ak\u0131\u015f\u0131ndaki par\u00e7ac\u0131klar\u0131n ak\u0131\u015f y\u00f6n\u00fcn\u00fc daha d\u00fczensiz hale getirir ve bu durum, kat\u0131 par\u00e7ac\u0131klar\u0131n yakalanmas\u0131na ve birikmesine elveri\u015flidir.<\/p>\n

4. \u0130skele y\u00fczeyindeki mikro \u00e7atlaklar ve i\u011fne delikleri nedeniyle, Al\u2082O\u2083 gibi par\u00e7ac\u0131klara g\u00fc\u00e7l\u00fc bir afiniteye sahip flor\u00fcr eriyikleri \u00f6nceden biriktirilmi\u015ftir; bu durum, tam bir filtre keki tabakas\u0131 etkisini ve g\u00fc\u00e7l\u00fc kimyasal adsorpsiyon kuvvetini desteklemi\u015f ve tutulan heterofaz par\u00e7ac\u0131klar\u0131n\u0131 yakalama yetene\u011fini art\u0131rm\u0131\u015ft\u0131r.<\/p>\n

5. Ayr\u0131ca, erime s\u00fcrecindeki s\u0131cakl\u0131k alan\u0131n\u0131n etkisi ve metal eriyik yap\u0131s\u0131n\u0131n iletim s\u00fcreci nedeniyle, ala\u015f\u0131m \u00e7\u00f6z\u00fcnen maddelerinin konsantrasyonunda taban fark\u0131 olu\u015fmal\u0131d\u0131r. Metal eriyik yeniden da\u011f\u0131t\u0131l\u0131r, b\u00fct\u00fcnle\u015fir, yeniden da\u011f\u0131t\u0131l\u0131r ve b\u00fct\u00fcnle\u015fir; bu da iyi bir ala\u015f\u0131mlama s\u00fcrecidir. Baz\u0131 y\u00fcksek erime noktal\u0131 metal fazlar ve bile\u015fikler yeniden gruplan\u0131r ve b\u00fcy\u00fcr; ince heterofaz ise filtreleme ve yakalama i\u015flemleri i\u00e7in faydal\u0131d\u0131r. Bu durum, filtreleme \u00f6ncesi ve sonras\u0131 H, Al\u2082O\u2083, Fe ve Ti fazlar\u0131n\u0131n konsantrasyonundaki de\u011fi\u015fimle de a\u00e7\u0131klanabilir. \u00d6zellikle, \u00e7ift a\u015famal\u0131 filtreleme veya g\u00f6zenek gradyanl\u0131 kal\u0131n plaka filtrelemesinde bu durum daha belirgindir. Bu nedenle, ayn\u0131 \u00f6n ko\u015fullar alt\u0131nda, yeni k\u00f6p\u00fck seramik filtre plakas\u0131, al\u00fcminyum eriyik i\u00e7indeki safs\u0131zl\u0131k faz\u0131n\u0131 y\u00fcksek oranda giderir ve filtreleme \u00f6ncesi ve sonras\u0131 statik bas\u0131n\u00e7 fark\u0131ndaki de\u011fi\u015fim zamanla daha belirgin hale gelir. Filtreleme \u00f6ncesi ve sonras\u0131 al\u00fcminyum eriyik i\u00e7indeki H i\u00e7eri\u011findeki fark da belirgindir. Elbette, k\u00f6p\u00fck seramik deliklerin se\u00e7imi ne kadar k\u00fc\u00e7\u00fck olursa, erimi\u015f al\u00fcminyumun safl\u0131\u011f\u0131 o kadar y\u00fcksek olur.<\/p>\n
