Tus nqi qis tshaj yogRMB54, 000/Ton! Silicon nqi poob dua
Lub lim tiam no, qhov sib pauv hloov pauv rau N-hom silicon cov ntaub ntawv yog nyob nruab nrab ntawm RMB 65,000-70,000/ton, nrog tus nqi nruab nrab ntawm RMB 68,000/ton, nqis { {6}}.29% piv rau lub lim tiam dhau los. Kev sib pauv hloov pauv rau cov ntaub ntawv ntom ntom monocrystalline yog nruab nrab ntawm RMB 57,000-62,{10}}/ton, nrog tus nqi nruab nrab ntawm RMB 59,500/ton, nqis 1.16% piv rau lub lim tiam dhau los. Tus nqi ntawm N-hom silicon cov ntaub ntawv tseem nyob ruaj khov, thaum tus nqi ntawm P-hom silicon cov ntaub ntawv muaj kev poob qis me ntsis. Tsis tas li ntawd, qhov sib txawv ntawm tus nqi siab thiab qis P-hom silicon cov ntaub ntawv tau nthuav dav, nrog rau tus nqi ntawm cov ntaub ntawv P-hom tsis zoo txuas ntxiv mus txog qhov qis tshiab.
Feem ntau cov tuam txhab tau ua tiav lawv cov xaj rau lub Kaum Ob Hlis lub lim tiam no, nrog 3 lub tuam txhab ua lag luam hauv cov ntaub ntawv n-hom thiab 6 tuam txhab lag luam ua cov khoom siv p-type. Txawm li cas los xij, qhov kev hloov pauv feem ntau me me. Tam sim no, downstream thov rau cov ntaub ntawv n-hom yog qhov zoo, nrog rau cov tuam txhab nquag yaum kom txiav txim txawm tias tus nqi siab thiab nrog lub sijhawm ntev. Cov khoom ntawm n-hom silicon cov ntaub ntawv yog nruj, thiab cov ntws mus rau hauv kev ua lag luam kwv yees tsuas yog nyob ib ncig ntawm 60, 000 tons, nrog rau cov nqi tseem muaj zog. Lub caij no, qhov kev thov rau cov khoom siv p-hom downstream yog qhov nyuaj rau kev tswj hwm vim muaj teeb meem hauv kev them nqi tsim khoom. Tsis tas li ntawd, qhov tsis ruaj tsis khov ntawm cov khoom lag luam silicon tshiab thaum lub sij hawm nce toj cov txheej txheem yuav ua rau muaj ntau tshaj li cov khoom siv p-type. Nyob rau hauv lub sij hawm luv luv, tus nqi poob ntawm p-type cov ntaub ntawv yuav txuas ntxiv mus nyem cov nqi tsim khoom, nrog qee cov kab qub qub raug cuam tshuam cov nqi, ua rau kev kaw lossis kev kho dua tshiab, thiab cov peev txheej tshiab yuav tsum ceev faj. Nws cia siab tias kev lag luam xav tau yuav nkag mus rau qhov kev poob qis hauv thawj peb lub hlis twg ntawm xyoo tom ntej, nrog rau kev poob qis ntawm cov nqi maj mam cuam tshuam rau kev lag luam khoom lag luam, thiab np-hom silicon cov khoom siv tus nqi sib txawv yuav tsum txuas ntxiv mus.
Raws li lub lim tiam no, muaj tag nrho ntawm 17 domestic polysilicon ntau lawm tuam txhab nyob rau hauv Suav teb. Txawm li cas los xij, ib qho ntawm lawv tau tso tseg kev tsim khoom rau kev hloov kho tshiab, uas tau muaj qee yam cuam tshuam rau kev tsim khoom. Vim huab cua huab cua tsis ntev los no, qee lub lag luam nyob hauv Xinjiang thiab Inner Mongolia tau cuam tshuam los ntawm kev thauj mus los tsis zoo, tab sis kev tsim khoom tseem tsis tau cuam tshuam. Raws li cov ntaub ntawv kev lis kev cai, nyob rau lub Kaum Ib Hlis, cov khoom ntim ntawm polysilicon yog 3202.5 tons, qhov txo qis ntawm 3.65% piv rau lub hli dhau los thiab ib xyoo-rau-xyoo txo ntawm 65.94%. Yog li ntawd, nws xav tias cov khoom siv ntawm polysilicon yuav tswj tau qhov kev nce zuj zus nyob rau lub Kaum Ob Hlis, nrog rau n-hom polysilicon tus nqi stabilizing thaum p-type polysilicon tus nqi tau poob qis me ntsis.
