Vim li cas tungsten carbide nqi nce?
Qhov nce hauv tungsten carbide tus nqi yog vim kev ua ke ntawm cov kev cuam tshuam ntawm cov khoom thiab thov.
Ua ntej, cov khoom siv:
1. Txo hauv Mining Qhov Ntsuas: txawm hais tias Suav nyiaj rau ntau tshaj li ib nrab ntawm lub ntiaj teb cov tungsten cov peev txheej, mining quota tau nruj ib xyoos tom qab xyoo. Thawj batch ntawm mining quotas rau 2025 tsuas yog 58,000 tons, uas tsawg dua li ob xyoos dhau los.
2. Nce cov nqi mining: lub tungsten cov ntsiab lus ntawm cov ore minesed los ntawm loj cov mines hauv Jiangxi, thiab lwm yam kev txo qis, thiab cov nqi mining yog nce ntau.
3. Cov ntaub ntawv tau muab hluav taws xob txuas ntxiv mus kom nruj: Txawm hais tias Baket Mine hauv Kazakhstan muaj cov peev txheej ntau, nws qib theem nrab tsuas yog 0.15%. Raws li 2024 daim ntawv tshaj tawm los ntawm Asmeskas Tebchaws Asmeskas GOological kev tshawb fawb, tus nqi smelting yog ho siab dua li kev lag luam nruab nrab. Nyob rau tib lub sijhawm, EU's tseem ceeb cov ntaub ntawv raw kom meej yuav tsum tau hais tias tus kheej tsis muaj peev xwm nce mus rau 70%, nrawm dua ntawm kev tsim kho ntawm cov saw hlau thoob ntiaj teb.
Thib ob, thov yog qhia resonance hla ntau lub haujlwm.
1. Kev lag luam iterological nyob rau hauv lub photovoltaic tau tsav qhov hloov ua tiav ntawm cov ntaub ntawv tsoos hlau los ntawm Tungsten Hlau thiab Pob Zeb Diamond hlau. Xyoo 2024, tus nqi nkag mus ntau tshaj li 23%, tsav tsheb nce ntxiv hauv tungsten tau ntau tshaj 25%.
2. Qhov kev thov rau tungsten carbide tawv alloys nyob rau hauv high- lub zog tsheb tsim kev lag luam thiab cov cuab yeej hluav taws xob tau loj hlob ntawm cov cuab yeej txhua xyoo ntawm ntau dua 12%.
3. Hauv daim teb ntawm cov ntaub ntawv tseem ceeb rau kev txhim kho cov khoom siv ntawm cov khoom siv siab heev, nrog tungsten cov khoom tshwj xeeb hauv lub cev underpinning nws cov tswv yim tus nqi. Nrog lub siab loj tshaj plaws ntawm 3,422 degree, thib ob tsuas yog rau cov pa roj carietlective ntawm 19.2} kub ua rau nws cov ntaub ntawv tseem ceeb rau kev txiav photovoltaic sificon wafers. Tungsten hlau nrog txoj kab uas hla ntawm 0.035 mm pab raws li cov khoom siv hauv paus ntawm cov khoom siv tseem ceeb rau sandiconductorrystal txiav tshuab.
4. Ntawm tus nqi tam sim no tsuas, Tuam Tshoj cov tungsten cov peev txheej yuav nyob ntev li 36 xyoo. Cov European Union tseem muaj kev txhawj xeeb ntau dua, teev tungsten li cov khoom tsis muaj tsawg heev.
Hauv cov ntsiab lus, qhov kev hloov pauv no nce qhov tseem ceeb qhia txog kev hloov pauv ntawm tungsten los ntawm ib qho khoom siv muaj nyob rau cov chaw muaj kev lag luam.
Hauv lub sijhawm luv luv, photovoltaic cov tuam txhab tau npaj rau lub Cuaj Hli, uas tej zaum yuav ua rau tus nqi nce. Txawm li cas los xij, poob qis cov khoom siv nyuaj heev yuav pom tias nws nyuaj rau cov nqi nce, raws li lawv cov txiaj ntsig yuav txo qis, muaj peev xwm ua rau kev yuav cov kev yuav khoom.
Hauv lub sijhawm ntev, kev txhim kho ntawm cov khoom siv hluav taws xob tshiab thiab cov tub rog kev lag luam yuav tsav ib qho ntxiv hauv Tungsten thov.
Thaum kawg, sawv hauv Tungsten tus nqi cuam tshuam txog cov teeb meem tob. Nyob rau hauv lub caij nyoog ntawm lub zog tshiab, uas tswj cov peev txheej tseem ceeb tswj tau kev pib hauv kev loj hlob. Qhov no tsis yog kev ua lag luam yooj yim, tab sis kev hloov pauv hauv ntiaj teb Industress Toj roob hauv pes.
