1. Dab tsi yog Hlau Silicon?
Hlau silicon, tseem muaj kev lag luam silicon, yog cov khoom ntawm smicon, yog cov khoom ntawm smatting silicon dioxide thiab carbonaceous txo tus neeg sawv cev hauv lub tshuab raj cua arc. Lub ntsiab tivthaiv ntawm silicon feem ntau yog siab dua 98.5% thiab qis dua 99.99%, thiab cov khoom siv tsis zoo yog hlau, tshuaj ntsuab, piv txwv, thiab lwm yam.
Hauv Suav teb, hlau silicon feem ntau muab faib ua cov qib sib txawv xws li 553, 441, 321, 1101, thiab lwm yam.
2. Thov ntawm hlau silicon
Cov kev siv hauv nqes hauv cov hlau uas muag ntawm cov hlau silicon feem ntau silicon, polysilicon thiab aluminium alloys. Xyoo 2020, Tuam Tshoj txoj kev noj tag nrho yog hais txog 1.6 lab tons, thiab kev sib piv siv tau yog raws li hauv qab no:
Silica gel muaj cov siab ntawm cov hlau silicon thiab yuav tsum muaj cov qauv tshuaj lom neeg, ua raws cov qauv tshuaj 553, feem ntau siv cov qauv tshuaj 553, feem ntau siv cov qauv tshuaj 553 #
Txawm li cas los xij, nyob rau hauv xyoo tsis ntev los no, qhov kev thov rau polysilicon hauv cov khoom cua hauv organic tau nce, thiab nws cov kev faib tau loj dua thiab loj dua. Qhov kev thov rau aluminium alloys tsis tau tsuas yog tsis nce, tab sis tau poob qis. Qhov no tseem yog ib qho tseem ceeb uas ua rau cov silicon ntau lawm tau muaj peev xwm ua kom muaj siab, tab sis muaj qhov tsis txaus ntseeg tsawg, thiab muaj qhov tsis txaus ntseeg ntawm cov hlau high-fricon silicon hauv kev ua lag luam.
3. Ntau yam xwm txheej hauv 2021
Raws li kev txheeb cais, txij lub Ib Hlis mus txog Lub Xya Hli 2021, Tuam Tshoj cov Silicon Cov Hluav Taws Xob Hlau Tshaj 466,000 Tons, ib xyoos-nyob rau xyoo ntawm 41%. Vim tias tus nqi qis ntawm cov hlau silicon hauv Suav teb nyob rau hauv ob peb xyoos dhau los, txuas nrog cov kev tiv thaiv ib puag ncig muaj cov kev ua haujlwm siab muaj cov nqi ua haujlwm tsawg lossis raug kaw ncaj qha.
Xyoo 2021, vim muaj kev lag luam txaus, tus nqi khiav haujlwm ntawm cov hlau silicon yuav siab dua. Lub zog hluav taws xob tsis txaus, thiab tus nqi khiav haujlwm ntawm cov hlau silicon yog qhov qis dua hauv cov xyoo dhau los. Kev Xav Tau-Sab Silicon thiab Polysilicon yog nyob rau hauv so lub xyoo no, nrog tus nqi siab, thiab muaj kev xav tau ntau rau cov hlau silicon. Cov yam ntxwv tshwj xeeb tau ua rau kom muaj kev tsis txaus siab tsis txaus ntawm hlau silicon.
Plaub, txoj kev hloov yav tom ntej ntawm cov hlau silicon
Raws li cov khoom siv thiab xav tau qhov teeb meem txheeb xyuas saum toj no, yav tom ntej qauv ntawm hlau silicor feem ntau yog nyob ntawm kev daws ntawm cov kev daws teeb meem yav dhau los.
Ua ntej tshaj plaws, rau zombie ntau lawm, tus nqi nyob siab siab, thiab ib co ib co zombie ntau lawm yuav rov ua ntau lawm, tab sis nws yuav siv sijhawm ib ntus.
Thib ob, lub zog fais fab tam sim no hauv qee qhov chaw tseem tab tom mus. Vim tias tsis muaj zog siv hluav taws xob, qee cov chaw ua haujlwm silicon tau ceeb toom txog kev txiav hwj chim. Tam sim no, tseem muaj cov khoom lag luam silicon hluav taws xob uas tau raug kaw, thiab nws tsis yooj yim rau rov qab hauv lub sijhawm luv luv.
Thib peb, yog tias tus nqi hauv tsev tseem ceeb, kev xa tawm yuav tsum qis dua. Tuam Tshoj cov silicon hlau feem ntau yog xa tawm rau cov tebchaws Esxias, txawm hais tias nws tsis tshua tau xa mus rau European thiab Asmeskas lub teb chaws. Txawm li cas los xij, Europeaner Silicon cov khoom lag luam tau nce vim tsis ntev los no siab lub siab thoob ntiaj teb. Ob peb xyoos dhau los, vim Tuam Tshoj tus nqi ua nqi hauv tsev, Tuam Tshoj ntau lawm tau ntau lawm, thiab lub ntim khoom lag luam loj. Tab sis thaum tus nqi muaj siab, lwm thaj chaw yuav nce ntau ntau lawm, thiab kev xa tawm yuav tsawg dua.
Tsis tas li, nyob rau hauv cov nqe lus ntawm cov dej ntws tawm, yuav muaj ntau silicon thiab polysilicon ntau lawm nyob rau hauv ib nrab xyoo ntawm lub xyoo. Nyob rau hauv cov nqe lus ntawm polysilicon, npaj tau ntau lub peev xwm ntawm lub xyoo no yog kwv yees li ntawm lub xyoo no yog kwv yees li ntawm cov hlau silicon yog xav tias yuav muaj txog 500,000 tons. Txawm li cas los xij, qhov kawg cov khoom lag luam cov khoom lag luam yuav tsis haus lub peev xwm tshiab, yog li kev ua haujlwm tag nrho ntawm qhov peev xwm tshiab yuav txo qis. Feem ntau, qhov tsis txaus ntawm cov silicon hlau yuav tsum tau txuas ntxiv thaum lub xyoo, tab sis cov kis yuav tsis muaj tshwj xeeb. Txawm li cas los xij, hauv ib nrab xyoo ntawm lub xyoo, silicon thiab polysilicon cov tuam txhab tsis cuam tshuam nrog cov hlau silicon yuav ntsib cov kev cov nyom.
