Daga Kayan Danye Zuwa Microfoda: Tsarin Samarwa Mai Tsauri
Mutane da yawa suna ɗauka cewa ana yin micropowder ne kawai ta hanyar niƙa manyan farin ƙwayoyin alumina da aka haɗa, amma gaskiyar magana ta fi rikitarwa.
1. Zaɓin Kayan Danye da Maganin Kafin A Yi Amfani da Su
Farin foda mai inganci mai hade da alumina yana farawa da foda mai inganci na masana'antu, tare da tsarkin Al₂O₃ sama da 99.5%. Ƙananan kayan tsarki na iya shafar tauri, fari, da kwanciyar hankali na sinadarai. Kafin narkewa, ana tace foda danye kuma a rarraba shi a cikin iska don cire ƙananan barbashi masu kauri da kuma tabbatar da girman barbashi iri ɗaya don narkewa mai inganci.
2. Narkewa da kuma ƙera wutar lantarki ta murhu
Sannan ana narkar da foda alumina da aka riga aka yi wa magani a cikin tanda mai matakai uku a zafin 2050-2150°C na tsawon awanni 4-6. A wannan yanayin zafi mai tsanani, alumina tana narkewa gaba ɗaya zuwa ruwa, yayin da ƙazanta ke rabuwa ta kuma kwanta saboda bambancin yawanta.
Kula da zafin jiki yana da matuƙar muhimmanci a wannan matakin. Ana saka na'urorin lantarki a cikin zurfin wurin da aka narke don tabbatar da dumama iri ɗaya. A lokacin sanyaya, ana sanyaya cikin sauri a yanayin zafi mai yawa, sannan a rage sanyaya a ƙananan yanayin zafi, wanda ke ba da damar samar da lu'ulu'u masu ƙarfi na α-Al₂O₃. Da zarar sun huce, kayan zai taurare ya zama lumps masu yawa, fararen alumina da aka haɗa da tauri da ƙarfi mai kyau.
3. Rarrabawa, Niƙawa, da Daidaito
Da farko ana murƙushe tubalan alumina da aka haɗa da na'urorin murƙushe muƙamuƙi, sannan a rage su kaɗan ta hanyar injin niƙa mai juyawa, sannan a ƙarshe a sarrafa su zuwa foda mai sikelin micron ta amfani da injin niƙa mai juyawa.
