\u00c7\u00f6z\u00fcnm\u00fc\u015f hidrojen, erimi\u015f al\u00fcminyumdan gaz-s\u0131v\u0131 aray\u00fcz\u00fcne do\u011fru hareket eder. Ard\u0131ndan inert gaz kabarc\u0131klar\u0131na ge\u00e7er ve y\u00fczeye do\u011fru y\u00fckselir.<\/p>\n

Kabarc\u0131klar eriyik i\u00e7inde ilerlerken, kalma s\u00fcreleri ve mevcut y\u00fczey alanlar\u0131 hidrojenin uzakla\u015ft\u0131r\u0131lmas\u0131n\u0131 etkiler. Etkili gaz-s\u0131v\u0131 temas alan\u0131 ne kadar b\u00fcy\u00fckse, hidrojenin al\u00fcminyumdan gaz faz\u0131na ge\u00e7me olas\u0131l\u0131\u011f\u0131 da o kadar artar.<\/p>\n

Flotasyon gaz giderme i\u015fleminde hangi gaz kullan\u0131l\u0131r?<\/h2>\n

Al\u00fcminyum eriyi\u011finin gazdan ar\u0131nd\u0131r\u0131lmas\u0131nda en yayg\u0131n olarak kullan\u0131lan gazlar azot ve argondur.<\/p>\n

Gaz\u0131n hidrojenle kimyasal olarak reaksiyona girmesi gerekmez. Bunun yerine, \u00e7\u00f6z\u00fcnm\u00fc\u015f hidrojenin i\u00e7ine ge\u00e7ebilece\u011fi bir gaz faz\u0131 sa\u011flar.<\/p>\n

\u0130nce Kabarc\u0131klar Neden \u00d6nemlidir?<\/h2>\n

\u0130nce, iyi da\u011f\u0131lm\u0131\u015f kabarc\u0131klar, ayn\u0131 gaz hacmi i\u00e7in b\u00fcy\u00fck kabarc\u0131klara k\u0131yasla daha geni\u015f bir toplam gaz-s\u0131v\u0131 aray\u00fczey alan\u0131 sa\u011flar.<\/p>\n

Bu, hidrojen k\u00fctle transferinin iyile\u015ftirilmesine yard\u0131mc\u0131 olur.<\/p>\n

Ancak, kabarc\u0131k boyutu yaln\u0131zca gaz bas\u0131nc\u0131yla belirlenmez. A\u015fa\u011f\u0131daki fakt\u00f6rlerden de etkilenir:<\/p>\n

Bu nedenle, \u00e7al\u0131\u015fma noktas\u0131 s\u00f6z konusu gaz giderme sistemine g\u00f6re optimize edilmelidir.<\/p>\n

      S\u0131cakl\u0131k \u00e7ok d\u00fc\u015f\u00fck olursa, erimi\u015f al\u00fcminyumun viskozitesi artar ve bu durum eriyik ak\u0131\u015f\u0131n\u0131 ve kabarc\u0131klar\u0131n da\u011f\u0131lmas\u0131n\u0131 etkileyebilir.<\/p>\n
