<\/p>\nTemizleyici ak\u0131, al\u00fcminyum ala\u015f\u0131m \u00e7\u00f6zeltisinin daha saf hale getirilmesi ve mekanik \u00f6zelliklerinin iyile\u015ftirilmesi amac\u0131yla gaz giderme ve kirlilik giderme i\u015flevini yerine getirebilir.<\/p>\n
Rafine edici maddenin eklenmesi s\u0131ras\u0131nda dikkate al\u0131nmas\u0131 gereken bir\u00e7ok \u00f6nlem vard\u0131r. A\u015fa\u011f\u0131da, bu maddenin kullan\u0131m\u0131na ili\u015fkin somut bir y\u00f6ntem a\u00e7\u0131klanmaktad\u0131r.<\/p>\n
Al\u00fcminyum \u00fcr\u00fcnlerin eritilmesi s\u0131ras\u0131nda uygun miktarda ar\u0131tma ak\u0131\u015fkan\u0131n\u0131n eklenmesi, s\u0131v\u0131 al\u00fcminyumda bulunan hidrojeni ve y\u00fczen oksitlenmi\u015f c\u00fcrufu etkili bir \u015fekilde giderilebilir.<\/p>\n
Temizleyici ak\u0131, y\u00fcksek s\u0131cakl\u0131kta kolayca ayr\u0131\u015f\u0131r; \u00f6zellikle ortaya \u00e7\u0131kan gaz kimyasal reaksiyona girmeye meyillidir ve c\u00fcruf kal\u0131nt\u0131s\u0131n\u0131n g\u00fc\u00e7l\u00fc adsorpsiyon kabiliyeti, hidrojenin eriyikten \u00e7\u0131kmas\u0131na olanak sa\u011flayabilir; bu nedenle c\u00fcrufun uzakla\u015ft\u0131r\u0131lmas\u0131 \u00fczerinde belirgin bir etki yaratabilir.<\/p>\n
Bu ar\u0131tma maddesi, saf al\u00fcminyum eritme konusunda y\u00fcksek standartlara sahip i\u015fletmeler i\u00e7in iyi bir tercihtir ve m\u00fc\u015fterilerimiz ile i\u015f ortaklar\u0131m\u0131z taraf\u0131ndan oybirli\u011fiyle takdir edilmi\u015f ve kabul g\u00f6rm\u00fc\u015ft\u00fcr.<\/p>\n
Ar\u0131tma maddesinin kullan\u0131m y\u00f6ntemi nispeten basittir; kullanmadan \u00f6nce bu maddeyle ilgili daha fazla bilgi edinebilirsiniz.<\/p>\n

Ayr\u0131ca, kullan\u0131m s\u00fcrecinde bir p\u00fcsk\u00fcrt\u00fcc\u00fc kullan\u0131labilir; p\u00fcsk\u00fcrtme i\u015flemi i\u00e7in ise inert gaz kullan\u0131lmas\u0131 daha uygun olacakt\u0131r. Miktar, s\u0131v\u0131 al\u00fcminyum k\u00fctlesinin yakla\u015f\u0131k 0,3%\u2019si kadard\u0131r. Al\u00fcminyum eriyiklerinin safl\u0131\u011f\u0131 nispeten y\u00fcksekse, al\u00fcminyum ar\u0131tma s\u0131ras\u0131nda erimi\u015f al\u00fcminyumun p\u00fcsk\u00fcrt\u00fclmesi y\u00f6ntemi, s\u0131v\u0131 al\u00fcminyumla daha geni\u015f bir temas alan\u0131 sa\u011flar.

Rafine etme ajan\u0131 \u00e7al\u0131\u015f\u0131rken, operat\u00f6r barometre ve toz besleme cihaz\u0131 arac\u0131l\u0131\u011f\u0131yla rafine etme ak\u0131\u015f\u0131n\u0131 rahat\u00e7a kontrol etmeli ve b\u00f6ylece al\u00fcminyum eriyiklerinin haddelenme derecesini denetlemelidir; bu da ikincil kirlili\u011fi azaltabilir.<\/p>\n
Eklenecek ar\u0131tma maddesinin miktar\u0131 0,10-0,20%'dir ve m\u00fc\u015fteri, kullan\u0131m s\u0131ras\u0131ndaki fiili duruma g\u00f6re se\u00e7im yapmal\u0131d\u0131r.<\/p>\n
Ar\u0131tma maddesi eklendikten sonra, ar\u0131tma maddesinin i\u015flevini tam olarak yerine getirebilmesi i\u00e7in iyice kar\u0131\u015ft\u0131r\u0131lmas\u0131 gerekir. Spek\u00fcl ve d\u00f6k\u00fcm miktar\u0131 duruma g\u00f6re belirlenmelidir. Genellikle d\u00f6k\u00fcm \u00f6nceden yap\u0131l\u0131r ve kalan k\u0131s\u0131m d\u00f6k\u00fclmemelidir.<\/p>\n
Ar\u0131tma maddesi, \u00e7e\u015fitli metal elementler i\u00e7erir ve bu da al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n eritilmesinde \u00f6nemli bir rol oynar. Eklendi\u011finde, al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n \u00f6zelliklerini de\u011fi\u015ftirebilir ve kullan\u0131m alanlar\u0131n\u0131 geni\u015fletebilir; bu nedenle ar\u0131tma maddesi, al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n eritilmesinde gereklidir.<\/p>","protected":false},"excerpt":{"rendered":"
