Silicon hlau tus nqi tuaj yeem zoo siab rau ib hnub thiab sib txawv me ntsis tom ntej, txawm tias tsis muaj "cov xov xwm loj." Tias yog vim li cas cov hlau silicon yog tus nqi- cov khoom lag luam rhiab heev nrog cov saw hlau xa khoom uas cuam tshuam sai rau cov kev hloov pauv ntawm cov nqi tsim khoom, kev thauj mus los, thiab luv luv - lub sijhawm yuav khoom. Hauv kev lag luam xa tawm, kev hloov pauv me me hauv kev xav lossis kev xa khoom tuaj yeem tshwm sim hauv cov lus hais ntev ua ntej lawv xav tias "ua yeeb yam" ntawm daim duab.
Kom nkag siab tias yog vim li cas tus nqi txav mus ntau zaus, nws pab pib los ntawm qhov chaw siv niaj hnub no. Ntawm Huangpu Chaw nres nkoj, kev lag luam xa tawm tam sim no nyob ruaj khov thoob plaws cov qib loj, thiab cov kab hauv qab no cuam tshuam txog qib ua haujlwm tshiab (FOB, se suav nrog):
| Qib | Tus nqi (USD / ton) | Hloov | Lus hais |

Yog li vim li cas cov lej no hloov ntau zaus?
Ib qho laj thawj loj yogtus nqi tsim khoom, tshwj xeeb tshaj yog lub zog. Silicon hlau yog tsim nyob rau hauv hluav taws xob rauv, thiab hluav taws xob yog tus nqi tseem ceeb. Thaum cov nqi hluav taws xob, khoom siv, lossis txoj cai hloov pauv hauv cheeb tsam tsim, cov lus hais feem ntau kho sai. Lwm tus nqi tsav tsheb yog cov khoom siv raw (xws li quartz thiab carbon reductants). Txawm tias tus nqi me me hloov pauv tuaj yeem thawb tus neeg xa khoom kom nruj kev muab lossis hloov kho ntau yam.
Ib qho laj thawj thib ob yogmuab lub sijhawm. Kev tu lub cub tawg, cov qauv tsim khoom raws caij nyoog, thiab lub sijhawm xa khoom tuaj yeem cuam tshuam cov khoom siv ntau npaum li cas rau ze rau - lub sijhawm xa tawm. Thaum qhov chaw muaj nruj, cov nqi tuaj yeem ruaj khov; Thaum cov khoom siv tau yooj yim thiab cov khoom muag txav mus, cov lus hais tuaj yeem muag me ntsis kom cov khoom ntws ntws.
Thib peb, tus nqi teb raukev sib dhos, tsis yog tag nrho kev thov. Yog tias kev nug thiab kev txiav txim tuaj txog hauv pawg hauv ib lub sijhawm luv luv, cov neeg muag khoom feem ntau tuav cov qib firmer. Yog tias kev nug qeeb, kev sib tham yuav yooj yim dua - txawm tias thaum kawg - cov neeg siv tsis tau hloov pauv ntau.
Thaum kawg,qib qauvteeb meem. Siab dua - qib purity nyiam2202muaj kev nkag siab ntau dua rau cov kev xav tau tshwj xeeb thiab cov khoom muaj, yog li lawv feem ntau nqa tus nqi zoo dua thiab tuaj yeem txav txawv ntawm nruab nrab - qib qib.
Hais txog peb cov khoom:
Peb muab cov qib silicon hlau nrog rau421, 2202, 3303, 441, thiab 553, nrog rau kev xa tawm -npaj ntim thiab COA kev txhawb nqa. Yog tias koj qhia qib, qhov nyiam, qhov ntau, thiab qhov chaw nres nkoj, peb tuaj yeem lees paub qhov tseeb FOB qib thiab lub sijhawm ua haujlwm tau raws li qhov chaw nres nkoj tam sim no.
