Vim li cas aluminium ntawv ci tsis 100% ntshiab?
Aluminium ntawv ci tsis yog 100% ntshiab rau ntau yam ntsig txog nws cov txheej txheem tsim, nqi, thiab cov khoom xav tau ntawm cov khoom kawg:
Kev tsim khoom:
Thaum lub sij hawm tsim cov ntawv txhuas, cov khoom me me ntawm lwm cov ntsiab lus, xws li hlau thiab silicon, feem ntau tau qhia. Cov impurities no tuaj yeem yog los ntawm cov khoom siv raw siv los yog cov khoom tsim khoom.
Txhim kho cov khoom:
Ntxiv me me ntawm lwm cov ntsiab lus tuaj yeem txhim kho cov khoom ntawm aluminium ntawv ci. Piv txwv li:
Lub zog: Lub xub ntiag ntawm kab kawm tuaj yeem ua rau muaj zog thiab ua haujlwm ntev ntawm cov ntawv ci.
Yooj yim: Qee cov impurities tuaj yeem txhim kho qhov yooj thiab formability ntawm cov ntawv ci, ua kom yooj yim rau kev siv wrapping thiab lwm yam kev siv.
Nqi:
Ua 100% ntshiab aluminium yuav kim dua thiab yuav tsis ua rau muaj kev txhim kho loj hauv kev ua haujlwm ntawm cov ntawv ci. Cov me me impurities feem ntau tam sim no tsis cuam tshuam rau cov ntawv ci kev ua tau zoo rau kev siv feem ntau, yog li kev tswj hwm qib qis purity me ntsis yog qhov zoo dua.
Tswv yim:
Hauv kev siv cov tswv yim, qhov me me ntawm impurities tam sim no nyob rau hauv aluminium ntawv ci tsis cuam tshuam rau nws txoj haujlwm ua noj, ntim khoom, lossis rwb thaiv tsev. Yog li ntawd, cov txiaj ntsig tsis zoo ntawm kev siv 100% ntshiab txhuas tsis ua pov thawj rau cov nqi ntxiv thiab qhov nyuaj koom nrog hauv kev tsim nws.
Zuag qhia tag nrho, aluminium ntawv ci yog tsim los nrog cov qib siab purity (feem ntau nyob ib ncig ntawm 99% txhuas), uas muab kev pom zoo ntawm tus nqi, kev ua tau zoo, thiab kev ua tau zoo rau nws txoj kev siv.
aluminium tuaj qhov twg?
Bauxite Mining
Qhov chaw: Bauxite ore muaj nyob rau hauv ntau nyob rau hauv cheeb tsam kub thiab subtropical. Cov neeg tsim khoom loj muaj xws li Australia, Guinea, Brazil, Jamaica, thiab Is Nrias teb.
Kev rho tawm: Bauxite feem ntau pom nyob ze ntawm qhov chaw thiab muab rho tawm los ntawm kev qhib qhov mining. Tom qab ntawd cov ore raug thauj mus rau cov chaw ua haujlwm.
Refining: Txoj Kev Bayer
Crushing thiab sib tsoo: Bauxite ore yog crushed thiab hauv av rau hauv cov hmoov zoo.
Dissolving: Cov hmoov bauxite yog tov nrog kub, concentrated tov ntawm sodium hydroxide (NaOH). Qhov no dissolves cov txhuas oxide (Al₂O₃) nyob rau hauv bauxite, tawm hauv qab impurities xws li hlau oxides thiab silica.
Kev qhia meej: Cov sib tov raug tso cai los daws, thiab cov impurities (hu ua cov av nkos liab) raug tshem tawm. Cov tshuaj ntxiv muaj cov tshuaj yaj yeeb yaj kiab.
Dej nag: Cov tshuaj yog txias, thiab txhuas hydroxide (Al (OH) ₃) precipitates tawm.
Calcination: Cov txhuas hydroxide yog rhuab rau hauv cov cub tawg los yog lub txaj fluidized calciners kom tshem tawm cov dej, tsim cov alumina anhydrous (Al₂O₃).
Alloying thiab Casting
Kev huv huv: Lub molten aluminium feem ntau ua kom zoo dua kom tshem tawm impurities.
Alloying: Txhuas tuaj yeem sib xyaw nrog lwm cov khoom xws li tooj liab, magnesium, silicon, thiab zinc los tsim ntau yam txhuas alloys nrog cov khoom tshwj xeeb.
