Economic nqi ntawm Titanium Recycling
Tsav los ntawm ob qho tib si thoob ntiaj teb cov peev txheej tsis txaus thiab lub hom phiaj "dual carbon", titanium recycling yog dhia los ntawm thaj chaw ntawm kev lag luam khoom seem mus rau qhov kev sib txuas zoo txhawb nqa siab -kev tsim khoom. Raws li cov hlau tau teev tseg raws li "cov ntsiab lus tseem ceeb ntawm cov ntxhia" los ntawm ntau lub teb chaws, titanium recycling tsis tsuas yog cuam tshuam cov peev txheej rov ua dua tshiab tab sis tseem cuam tshuam ncaj qha rau cov saw hlau ruaj ntseg hauv aerospace, lub zog tshiab, thiab kev kho mob. Nws cov txiaj ntsig kev lag luam tau raug tso tawm sai sai los ntawm kev siv thev naus laus zis thiab kev taw qhia txoj cai, ua rau nws yog ib qho ntawm - loj hlob sub- cov haujlwm hauv kev lag luam hlau rov ua dua tshiab.
Tus nqi ntawm titanium recycling feem ntau yog tshwm sim nyob rau hauv tus nqi siab thiab lub zog noj ntawm nws thawj extraction. Piv txwv li, kev tsim cov sponge titanium xav tau 15,000 kWh ntawm hluav taws xob ib tuj, ua rau nws cov nqi ntau dua 10 npaug ntawm cov hlau zoo tib yam. Tsis tas li ntawd, 75% ntawm lub ntiaj teb titanium ore reserves yog concentrated nyob rau hauv Australia thiab South Africa, thiab Tuam Tshoj, raws li lub ntiaj teb no cov neeg siv khoom loj tshaj plaws, tau ntev cia siab rau txawv teb chaws ntau tshaj 80%. Tawm tsam qhov teeb meem no, rov ua dua ib tuj ntawm titanium alloy tuaj yeem txuag tau 60% ntawm kev siv hluav taws xob thiab txo cov pa roj carbon emissions los ntawm 90%, nrog rau cov khoom siv raw cov nqi tsuas yog 35% ntawm cov thawj titanium. Noj Airbus 'Tianjin cog ua piv txwv, los ntawm kev rov ua dua cov khoom siv dav hlau, nws txuag tau tshaj 20 lab yuan ib xyoos ib zaug hauv cov khoom siv raw, thaum tib lub sijhawm txo cov pa roj carbon monoxide sib npaug rau cog 12,000 tsob ntoo. Qhov no raug kaw- voj qauv ntawm "peev txheej- khoom- cov khoom siv rov ua dua tshiab" yog hloov kho tus nqi faib khoom ntawm lub ntiaj teb titanium kev lag luam saw.
Kev siv thev naus laus zis yog qhov tseem ceeb tsav tsheb rau kev tso tawm tus nqi lag luam ntawm titanium rov ua dua tshiab. Hauv cov txheej txheem ib txwm muaj, tus nqi rov qab ntawm titanium- muaj cov dej khib nyiab tau ntev dua qis dua 65% vim yog daim ntawv nyuaj ntawm titanium ions, tsis tshua muaj siab, thiab cuam tshuam los ntawm impurities. Txawm li cas los xij, kev taw qhia ntawm ion txauv resin thev naus laus zis tau nce lub peev xwm ntawm titanium adsorption mus rau 200 mg / g, tsib zaug ntawm cov tshuaj los nag, thaum txo cov nqi khiav hauj lwm los ntawm 60%. Piv txwv li, tus tsim khoom loj titanium dioxide, tom qab siv cov thev naus laus zis no, rov ua dua 800 tons ntawm titanium hlau txhua xyoo, ncaj qha nce nyiaj tau los ntawm 30 lab yuan thiab txo cov sludge ntim los ntawm 90%. Nyob rau hauv siab -kawg teb, lub tshuab nqus tsev melting thiab sorting tshuab tuaj yeem ua rau kom purity ntawm titanium pov tseg rau 99.99%, ua tau raws li qhov yuav tsum tau muaj ntawm aerospace- qib titanium alloys; 3D luam ntawv hmoov metallurgy txheej txheem ua kom cov khoom siv titanium rov ua kom tiav kev ua tau zoo piv rau cov ntaub ntawv nkauj xwb, thaum txo cov nqi los ntawm 40%. Cov kev siv thev naus laus zis no tau ua kom rov ua dua titanium kom dhia los ntawm "qis-kawg cov khoom lag luam" mus rau "siab-kawg cov khoom siv." Cov xwm txheej xws li SpaceX's Starship foob pob hluav taws siv 20% rov ua dua titanium alloy thiab Tesla's 4680 roj teeb casing siv cov titanium rov ua kom pom qhov ua tau zoo ntawm cov khoom siv titanium.
Qhov kev txhawb siab dual ntawm txoj cai thiab kev lag luam rog tau nthuav dav ntxiv rau kev lag luam los ntawm titanium recycling. EU's Circular Economy Action Plan xav kom 90% rov ua dua tus nqi rau cov hlau ua lag luam los ntawm 2030, US Inflation Reduction Act muab $ 300 se credit rau ib tuj rau cov tuam txhab uas siv titanium rov ua dua, thiab Tuam Tshoj 14th Tsib -Year Plan qhia meej meej rau kev tsim cov khoom siv hlau. Tsav los ntawm txoj cai faib nyiaj, lub ntiaj teb titanium recycling tus nqi nce 12 feem pua cov ntsiab lus rau 41% hauv 2024 piv rau 2019, nrog rau kev lag luam aerospace ntau dua 65%. Nyob rau sab kev lag luam, lub ntiaj teb titanium recycling kev lag luam tau kwv yees kom ncav cuag 13.55 billion yuan hauv kev muag khoom los ntawm 2031, nrog kev loj hlob txhua xyoo ntawm 9.1% los ntawm 2025 txog 2031, deb tshaj qhov kev loj hlob ntawm thawj titanium lag luam. Qhov kev loj hlob no tsis yog los ntawm cov txiaj ntsig zoo xwb tab sis kuj los ntawm kev nkag mus ntawm cov titanium rov ua dua rau hauv siab -kawg sectors- cov khoom siv orthopedic ua los ntawm cov titanium rov ua dua hauv kev kho mob muaj 5-8 npaug ntau dua tus nqi ntxiv, thiab qhov xav tau tawg rau lithium titanate cov roj teeb mining tau ua rau cov khoom siv hluav taws xob tshiab.
Los ntawm cov peev txheej ruaj ntseg mus rau kev txhim kho kev lag luam, kev lag luam tus nqi ntawm titanium recycling transcends yooj yim cov nqi txuag. Thaum lub ntiaj teb vies rau lithium, cobalt, thiab npib tsib xee, titanium recycling technology yog ntsiag to reshaping lub industrial toj roob hauv pes. Tuam Tshoj imports hluav taws xob-qib titanium los ntawm Nyiv ib xyoos ib zaug ntawm tus nqi siab tshaj 3 lab yuan ib ton, thiab cov titanium no tuaj yeem tsim los ntawm titanium-muaj cov khib nyiab tau los ntawm cov tuam txhab Nyij Pooj los ntawm Tuam Tshoj. Qhov tsis txaus ntseeg no "rov qab ntws ntawm cov peev txheej" yog yuam kom Tuam Tshoj ua kom nrawm dua hauv kev siv thev naus laus zis. Nrog rau kev siv thev naus laus zis xws li ion pauv resins thiab lub tshuab nqus tsev, thiab kev txhawb nqa ntawm "recycling-regeneration-remanufacturing" kaw-loop qauv, titanium recycling yuav tsum dhau los ua qhov txuas tseem ceeb txuas kev ruaj ntseg, carbon neutrality lub hom phiaj, thiab kev lag luam siab {{10} yuav txuas ntxiv mus rau hauv lub ntiaj teb no industrial transformation.
