Heerka fulinta leben aluminium sare iyo cabbirka caadiga ah

Heerka fulinta leben aluminium sare iyo cabbirka caadiga ah


Sida leben iska celin caadi ah, leben sare oo aluminium ah magacyo badan ku leeyihiin codsiyada maalinlaha ah. Halkan waxaa ah soo koobida magacyada caadiga ah ee caanka ah ee qof walba.

Halabuurka kiimikada ee bauxite sare ee aluminiumka sare ee kiimikada ee alumina alumina sare, qaybaha ugu muhiimsan waa Al2O3 iyo SiO2. Halabuurka kiimikaad ee caadiga ah waxaa loo kala saaraa iyadoo loo eegayo ka kooban kiimikada iyo isticmaalka bauxite.

Fasalada 1 ilaa 6 waxay ku habboon yihiin nooca duralumin monohydrate; Fasalka 7 wuxuu ku habboon yahay nooca aluminium. Al2O3 waa qaybta ugu muhiimsan ee bauxite. Mar kasta oo ay ka kooban tahay, ayaa ka sii wanaagsan. Wax soo saarka hadda ee alumina warshaduhu waxay u baahan tahay in saamiga aluminium iyo silikoon uusan ka yarayn 3.0. Okssaydhyada kale waxaa loo arkaa inay yihiin wasakh. SiO2 waa wasakh waxyeello leh soo saarista aluminium ee habka alkaline. Maaddada sare ee SiO2 ee bauxite waxay yarayn doontaa waxtarka wax soo saarka ee dhalaalidda corundum brown ama soo saarista aluminium warshadaha.

TiO2 iyo Fe2O3 ee alumina bauxite sare waa labada wasakh ee ugu weyn. Waxa ku jira TiO2 waxay u janjeertaa inay kordhiso isku mar marka la kordhiyo Al2O3. Daraasaduhu waxay muujiyeen in: TiO2 in alumina bauxite sare ee sare waxay inta badan samaysaa xal adag oo leh mullite, iyo qadarka gelitaanka marxaladda galaaska waa yar yahay, taas oo aan u wanaagsanayn sintering alaabta, laakiin waxaa faa’iido leh in la hagaajiyo sifooyinka farsamada heerkulka sare ee alaabta; Bauxite, TiO2 waxay gashaa marxaladda muraayadda wax badan, taas oo kordhin doonta qadarka dareeraha dareeraha waxayna yareyn doontaa viscosity ee wajiga dareeraha, kaas oo ku habboon sintering, laakiin ma aha mid ku habboon hagaajinta heerkulka sare ee alaabta. Okssaydhka birta alkali ee K2O iyo Na2O ee alumina bauxite sare waa qulqulo aad u xoog badan, waxayna soo saaraan weji dareere ah heerkul hoose. Marka waxa ku jira uu aad u sarreeyo, waxa ay saamayn doontaa halabuurka wejiga iyo waxa ku jira clinker-ka iyo badeecada, waxaanay si xun u saamaynaysaa waxqabadka alaabta. Maaddada CaO ee alumina bauxite-ka sare ayaa guud ahaan hooseeysa, qiyaastii 0.2%. Jiritaankeedu wuxuu wax u dhimayaa waxqabadka heerkulka sare ee alaabta, iyo waxa ku jira ayaa sidoo kale xaddidan xaaladaha farsamada.
