Taw qhia rau cov txheej txheem ntau lawm thiab cov ntawv thov ntawm tus thawj txhuas

Thawj txhuas kev hais txog ntshiab aluminium ncaj qha ua kom zoo los ntawm electrolytic bauxite (mas alumina, AL₂O₃), es tsis txhob siv cov txhuas ua los ntawm kev rov ua dua tshiab khawb txhuas thiab rov kho dua. Cov hauv qab no yog cov lus qhia ntxaws ntxaws rau thawj txhuas:

1. Cov txheej txheem ntau lawm

   Kev tsim cov thawj txhuas tsuas yog tso cai rau hauv chav Xus-Hérice scit, Thiab cov kauj ruam tseem ceeb yog raws li hauv qab no:

   • Bauxite Mining: rho tawm alumina los ntawm ore

   • Txheej Txheem Purification Purification: Dissolving Bauxite hauv sodium hydroxide kom tau txais cov ntshiab alumin

   • Txo Cov Hluav Taws Xob: Hauv kev siv hluav taws xob electrolytic, alumina thiab cryolite (flux) yog energized ntawm qhov kub (Txog 950 ° C) thiab decomposed rau hauv kua txhuas thiab oxygen

   • Timing: Cov kua txhuas tau los ntawm electrolysis yog txias thiab nrum rau hauv txhuas ingots (xws li txhuas bishts, Aluminium Daim Hlau, lwm yam.)

2. Nta

   • Siab huv: Lub purity ntawm thawj txhuas feem ntau ≥99.6%, nrog ob peb impurities thiab ruaj khov ua tau zoo

   • Kev ua tau zoo heev: kev ua siab loj, kev coj ua, thiab corrosion tsis kam yog qhov zoo dua li rov ua txhuas, Haum rau cov ntawv thov siab

   • Kev Siv Hluav Taws Xob Loj: Kev tsim khoom ntawm 1 tuj ntawm thawj txhuas noj txog 13,000-15,000 KWH ntawm hluav taws xob, thiab cov pa roj carbon emissions loj

3. Chaw thov

   • Thawj txhais txhuas yog siv hauv kev lag luam nrog cov khoom ua tau zoo

   • Ib tug tub rog: Cov dav hlau qauv txheem, Nkoj cov khoom siv hluav taws xob

   • Hluav taws xob hauv: High-voltage cables, Tshuaj Ntawm Nyiaj

   • Kev Ntim High-Xaus: Khoom Noj Khoom Haus-Qib Aluminium Ntawv Nyiaj, kaus poom

   • Kev Lag Luam Automotive: Lub cev yuag yuag, High-zog qhov chaw

4. Koom xim Aluminium. rov qab ua txhuas

   • Kev Sib Piv Thawj Txhuas Rov Ua Dua Aluminium

   • Cov Khoom Siv Raw Bauxite (tus nas) Nkim Aluminium Recycling

   • Purity ≥99.6% feem ntau 90-98%

   • Zog siv tsis tshua muaj siab (Kev Txhim Kho Cov Txheej Txheem Electrolysis) Tsuas 5% ntawm thawj txhuas

   • Tus nqi siab dua qis dua

   • Kev tiv thaiv ib puag ncig cov pa roj carbon emissions puas tau txo qis kev noj haus

   • Cov ntawv thov High-kawg Kev Tsim Kev Lag Luam General, Tsev cov ntaub ntawv, Txhua Yam Yuav Tsum Tau

5. Kev nyuaj ib puag ncig thiab tiam

   • Cov teeb meem carbon footcted: Ultrasonicselic Altries ntawm Fossil Zog rau Kev Siv Hluav Taws Xob rau cov hluav taws xob thiab yog cov emitter loj hauv kev lag luam hnyav

   • Ntsuab hloov pauv: Qee cov tuam txhab tig mus rau hydroPower lossis hnub ci fais fab mov (xws li “HydroCower Aluminium”), lossis txhim kho inert kev siv tshuab los txo cov roj carbon emissions

   • Kev lag luam ncig: Cov feem ntawm cov rov ua dua qub tau nce, Tab sis thawj txhuas tseem yog qhov tseem ceeb hauv qhov chaw siab kawg

Lub ntsiab

Thawj txhuas yog cov khoom siv yooj yim. Txawm hais tias tus nqi tsim khoom yog qhov siab thiab nws tsis yog ib puag ncig phooj ywg, nws cov kev ua tau zoo ua rau nws indispensable hauv cov chaw tseem ceeb. Yav tom ntej, Lub Sustainability ntawm thawj txhuas yuav maj mam txhim kho los ntawm kev ua kom zoo ntawm lub zog qauv thiab kev txhim kho ntawm cov txheej txheem rov ua dua tshiab.
