Kev txiav txim siab ntawm tus nqi yog los ntawm kev sib txheeb ntawm cov khoom thiab kev xav tau. Lwm xyoo, kev ua lag luam yuav muaj ntau qhov kev cia siab zoo rau ntawm qhov xav tau, tab sis yuav muaj qee qhov sib txawv ntawm sab khoom siv. Lub ntsiab yog vim li cas qhov kev sib tw tseem ceeb ntawm cov khoom siv silicon cov tuam txhab los ntawm kev tswj hwm tus nqi. Txhua tus nqi nkhaus sib txawv, uas ua rau cov nqi sib txawv thiab qhov muaj peev xwm ntau lawm. Muaj qhov sib txawv ntawm cov nqi hauv kev ua haujlwm, yog li tsab xov xwm no yuav pib nrog qhov kev siv tus nqi sib txawv ntawm cov tuam txhab ua cov khoom siv silicon, suav cov khoom siv silicon cov nqi chaw rau xyoo tom ntej, thiab ua qhov kev tshawb xyuas tus nqi.
Nqi yog qhov kev sib tw tseem ceeb ntawm cov tuam txhab silicon
Cov ntaub ntawv silicone yog homogenized cov khoom lag luam, thiab kev sib tw ntawm cov lag luam yog cov tswj hwm tus nqi. Tus nqi ntawm cov khoom siv silicon ua rau 33%, 32% thiab 17% ntawm tus nqi hluav taws xob, silicon hmoov thiab txo nqi feem. Nyob rau hauv cov nqe lus ntawm chav tsev, nyob rau lub sijhawm tam sim no, cov tuam txhab ua khoom siv silicon muaj qhov ua tiav lawv cov kev xa mus ua haujlwm hauv thaj chaw qis qis, thiab muaj qhov sib txawv me me ntawm cov nqi hluav taws xob yuav khoom; txhua cov tshuaj kua roj silicon yog txiav tawm, thiab cov nqi yuav khoom tsis txawv ntau. Qhov tseeb ua rau muaj nuj nqi sib txawv ntawm ntau lub tuam txhab yog qhov sib txawv ntawm cov khoom siv ntau lawm, uas yog qhov tseem ceeb hauv kev siv fais fab rau ib tuj, seb nws tuaj yeem ua dhau-ntau lawm diluted thiab txo nqi. Los ntawm qhov pom ntawm kev tsim khoom, cov khoom siv silicon npaj thev naus laus zis tau paub tab lawm. Feem ntau cov tuam txhab txais yuav kev txhim kho Siemens txheej txheem rau ntau lawm. Cov txheej txheem tsim khoom yog ib txwm zoo ib yam. Peb ntseeg tias lub hauv paus ntsiab lus cuam tshuam rau kev ua haujlwm ntau lawm yog kev tswj ntawm cov txheej txheem ntws.
Lub chaw nqus dej ntawm silicon nyob rau lwm xyoo qhov twg?
Tus nqi ntawm cov khoom siv silicon yog nyob ntawm cov khoom siv thiab thov qauv thiab kev lag luam tus nqi nkhaus. Peb kwv yees hais tias yuav muaj kev thov txog 450,000 tons ntawm monocrystalline cov ntaub ntawv hauv 21 xyoos. Los ntawm qhov pom ntawm kev muab khoom, peb kwv yees tias lub ntiaj teb monocrystalline ntau lawm muaj peev xwm hauv 21 xyoo yog kwv yees li 477.6 lab. Cov peev txheej tsim muaj peev xwm yog them nyiaj tshaj, thiab tus nqi ntawm cov khoom siv silicon muaj qab nthab. Txawm li cas los xij, vim tias qhov sib txawv ntawm cov nqi tsim tawm ntawm ntau lub tuam txhab, cov peev txheej tsim muaj peev txheej yuav tsis qhib. Peb ntaus nqi ntawm lub tuam txhab nqi qis los ntawm siab. Qhov peev xwm ntau lawm sib xws rau qhov kev thov 450,000 tons ntawm monocrystalline cov ntaub ntawv poob ze rau hauv lub peev xwm ntawm Wacker hauv lub teb chaws Yelemees, thiab tus nqi tsim khoom ntawm WACKER yog 7.5 Kwv yees li 10,000 yuan / ton, xav txog tus nqi se ntxiv, nws ntseeg tau tias tus nqi nyob rau hauv 21 xyoos yuav yog 80-85 yuan / ton (suav sau nrog).
Kev Tsom Xam Qhov Tseeb
Cov ntaub ntawv Silicon muaj qee yam khoom siv roj, thiab kev hloov pauv tus nqi tau cuam tshuam ntau dua rau qhov txiaj ntsig. Yog li, peb tau ntsuas qhov txiaj ntsig ntawm cov khoom siv silicon cov tuam txhab ntawm cov nqi sib txawv. Coj Tongwei ua piv txwv, kwv yees tias xyoo tom ntej' s silicon khoom muag ntim khoom yog 95,000 tons, yog tias cov khoom siv silicon cov khoom lag luam nyob ruaj khov ntawm 85,000 / tuj, qhov sib txuam txhua xyoo cov nyiaj tau los ntawm kev lag luam khoom lag luam silicon yog 2.53 billion yuan. Yog tias tus nqi nce mus txog 100,000 / tuj, ib feem ntawm qhov peev nyiaj txhua xyoo ntawm cov khoom lag luam silicon coj ua lag luam yog 3.609 billion yuan. Nyob rau tib lub sijhawm, peb kwv yees hais tias tus nqi ntawm cov ntaub ntawv silicon yuav nce mus txog 85,000 yuan / tuj, thiab cov nyiaj khwv tau los kawg ntawm cov kev lag luam hauv nqes dej yog suav txog 19%, uas tseem nyob hauv ib qho kev txiav txim siab tau. Peb ntseeg hais tias qhov nyiaj qis tshaj plaws txais nyiaj tau txais los ntawm kev nqes dej kev lag luam yog 15%, thiab tus nqi se nrog cov nqi ntawm cov khoom siv silicon yog xam ua 111,000 yuan / tuj.
