Q1: Dab tsi yog cov khoom tseem ceeb ntawm lub cev ntawm txhuas?
Aluminium yog ib lub teeb yuag nrog cov ntom ntom txog ib feem peb uas cov hlau. Nws muaj cov thermal thiab hluav taws xob zoo heev, ua rau nws muaj txiaj ntsig hauv kev sib pauv cua sov thiab xaim. Cov hlau yog malylable heev, tso cai rau nws kom muab rau hauv cov ntawv puab nyias lossis muab tso rau hauv cov duab nyuaj. Tsis tas li ntawd, txhuas tsis yog sib nqus thiab tiv thaiv kev ua kom xeb vim nws cov olide oxide txheej. Cov khoom no ua rau nws zoo tagnrho rau kev ntim, tsim kho, thiab hluav taws xob.

Q2: Vim li cas cov siv txhuas hauv cov khoom noj ntim khoom?
Aluminium ntawv nyiaj yog qhov tsis zoo rau lub teeb, oxygen, thiab noo noo, khaws cia khoom noj tshiab. Nws tsis muaj tshuaj lom thiab tsis hnov ​​qab tsam cov zaub mov feem ntau, ua kom muaj kev nyab xeeb. Tus Hlau Nyaj Zeem Rauv txo cov nqi tsheb thauj mus los, thaum nws rov ua dua tshiab txhawb kev ruaj khov. Los ntawm cov kaus poom tshuaj rau chocolate wrappers, txhuas ntim yog ubiquitous. Nws lub peev xwm los tiv thaiv siab thiab qis zaus kuj ua rau nws haum rau kev siv lub freezer-rau-cub.

Q3: Yuav ua li cas ua txhuas piv rau lwm yam hlau ua lub zog?
Ntshiab txhuas yog cov mos tab sis tau txais lub zog thaum txuam nrog cov ntsiab xws li tooj liab lossis magnesium. Thaum tsis muaj zog li hlau, nws lub zog-rau-hnyav piv yog qhov tshwj xeeb, tau txais txiaj ntsig aerospace thiab kev lag luam tsheb. Aluminium alloys tuaj yeem phim qee cov hlau hauv lub sijhawm thaum muaj ntau dua ntais. Txawm li cas los xij, nws yog tsawg dua hnav-resistant dua titanium lossis tawv tawv hlau. Cov engineers feem ntau xaiv txhuas rau cov ntawv thov uas hnyav txuag tawm qhov xav tau kev tawv heev.

Q4: Cov txiaj ntsig ib puag ncig ntawm Aluminium rov ua dua tshiab li cas?
Rov qab ua dua cov txhuas txuag mus txog 95% ntawm lub zog uas yuav tsum muaj rau kev tsim cov khoom lag luam. Cov hlau tuaj yeem rov qab ua dua tsis tau yam tsis tas yuav poob zoo, txo cov chaw pov tseg. Ub rov qab ib qho ntawm txhuas tiv thaiv 9 tons ntawm co-emissions. Cov kaus poom haus yog cov khoom siv uas tau rov ua dua nyob thoob ntiaj teb, nrog tus nqi siab dua. Qhov no kaw-voj system ua rau aluminium ib daim ntawv dai daim ntawv rau puag ncig kev lag luam kev lag luam.

Q5: Cov tshuaj tua kab mob li cas los ntawm bauxite ore?
Bauxite yog ua kom zoo rau hauv Alumina (Aluminium oxide) los ntawm cov txheej txheem Bayer, uas siv sodium hydroxide. Alumina yog tom qab ntawd smelted ntawm Hall-hérice cov txheej txheem, qhov twg electrolysis cais ntshiab txhuas. Lub zog no lub zog-cov txheej txheem tseev kom muaj hluav taws xob tseem ceeb, feem ntau muaj los ntawm hydropoPower. Kev nrhav lub hom phiaj los txo cov pa roj carbon monissions hauv kev tsim cov txheej txheem. Kev ua dua tshiab thiab lwm txoj kev rho tawm tau raug tshawb fawb txhawm rau txhim kho kev ruaj khov.
