Silicones cov ntaub ntawv tsis yog tsuas yog ib qho tseem ceeb ntawm cov ntaub ntawv tshiab kev lag luam ntawm lub teb chaws txoj kev lag luam tawm tswv yim, tab sis kuj yog ib qho tseem ceeb txhawb cov khoom siv rau lwm yam lag luam tawm tswv yim.

Nrog rau kev nthuav dav ntxiv ntawm daim ntawv thov teb, qhov kev thov loj loj tau ua rau silicones yog ib qho ntawm cov khoom siv tshuaj lom neeg nyiam tshaj plaws tam sim no.

Qhov feem ntau ntawm kev siv silicones hauv tsev yog nyob rau hauv kev tsim kho, hluav taws xob, hluav taws xob thiab lub zog tshiab, kev kho mob, thiab kev saib xyuas tus kheej.Ntawm lawv, kev tsim kho thaj chaw tam sim no yog lub ntsiab lus dav dav rau kev siv silicones, suav txog li 30%.

Ntxiv rau qhov kev loj hlob tsis tu ncua ntawm kev thov rau cov khoom siv silicones hauv kev lag luam ib txwm muaj, kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig kev lag luam xws li photovoltaics thiab lub zog tshiab, nrog rau kev txhim kho cov kev lag luam tawm tshiab xws li ultra-high thiab ultra-high voltage power grid siv. , cov khoom siv ntse ntse, 3D luam ntawv, thiab 5G, txhua tus muab cov ntsiab lus xav tau tshiab rau silicones.

Txheej txheem cej luam ntawm Silicones

Silicones yog ib lo lus dav dav rau silicon organic compounds, uas yog synthesized thiab hydrolyzed los ntawm hlau silicon thiab chloromethane.

Thawj kauj ruam hauv kev tsim cov silicones yog tsim cov methylchlorosilane, uas tom qab ntawd hydrolyzed kom tau monomethyltrichlorosilane, dimethyldichlorosilane, thiab trichlorosilane.Dimethyldichlorosilane yog lub ntsiab monomer ntau yam ntawm cov organic silicon, nrog nws cov khoom tseem ceeb downstream yog silicone roj hmab thiab silicone roj.

Tam sim no, lub peev xwm ntawm silicones tau hais nyob rau hauv Suav teb feem ntau yog hais txog kev tsim muaj peev xwm ntawm methylchlorosilane, thaum tam sim no cov ntaub ntawv ntau lawm yog tag nrho raws li kev tsim cov dimethylsiloxane.

Silicones kev lag luam saw

Kev lag luam silicones feem ntau muab faib ua plaub qhov txuas: silicones raw khoom, silicones monomers, silicones intermediates, thiab silicones sib sib zog nqus ua cov khoom.Muaj tsawg dua cov tuam txhab tsim khoom rau cov khoom siv raw, monomers, thiab cov khoom nruab nrab, thaum cov dej ntws sib sib zog nqus ua rau muaj ntau yam khoom thiab muaj peev xwm ntau lawm.

Silicone raw khoom

Kev tsim cov txheej txheem ntawm silicones muaj feem ntau ntawm cov khoom siv raw.Cov khoom siv silicones yog cov khoom siv silicone hmoov, uas tau npaj hauv kev lag luam los ntawm kev txo cov quartz nrog coke nyob rau hauv ib qho hluav taws xob arc rauv.

Kev tsim cov khoom siv silicone siv ntau cov khoom siv silicone thiab lub zog, thiab ua rau muaj kuab paug ib puag ncig.Yog li ntawd, kev ruaj khov thiab cov khoom zoo ntawm cov khoom siv silicone raw khoom tau dhau los ua qhov kev lav zoo rau cov khoom siv silicone.

Raws li SAGSI, xyoo 2020, lub ntiaj teb kev lag luam silicone muaj peev xwm yog 6.23 lab tons, thaum Tuam Tshoj lub peev xwm tsim tau yog 4.82 lab tons, suav txog 77.4%.

Silicones monomers thiab intermediates

Cov khoom siv hauv tsev ntawm silicones monomers thiab intermediates tso nyiaj ntau dua 50% ntawm lub ntiaj teb tag nrho, ua rau nws yog tus xa khoom loj tshaj plaws ntawm silicones monomers thiab intermediates hauv ntiaj teb.Vim yog lub xeev tsis ruaj khov ntawm silicones monomers, cov tuam txhab feem ntau ua ke cov monomers rau hauv nruab nrab xws li DMC (dimethylsiloxane) lossis D4 rau muag.

Muaj ob peb hom thiab specifications ntawm silicones monomers thiab intermediates.

Dimethyldichlorosilane yog tam sim no siv ntau tshaj plaws silicones monomer, suav txog ntau dua 90% ntawm tag nrho cov nyiaj monomer.

Kev nkag mus rau kev lag luam silicones yog siab, uas tau nce mus rau 200000 tons thiab yuav tsum muaj tsawg kawg yog 1.5 billion yuan ntawm peev peev.Lub siab nkag mus rau kev lag luam yuav txhawb nqa qhov sib txawv ntawm monomer ntau lawm muaj peev xwm concentration rau cov lag luam ua lag luam.

Tam sim no, tsuas yog ib tug me me ntawm cov tuam txhab uas muaj txaus technologies tsub zuj zuj thiab ua tiav loj-scale ntau lawm, nrog ntau tshaj 90% ntawm cov muaj peev xwm muab faib rau saum 11 tuam txhab uas muag.

Lub concentration ntawm silicones monomer muaj peev xwm tsim tau kuj muab ntau qhov chaw sib tham rau cov lag luam hauv qab.

Dichlorodimethylsilane

Hais txog kev muab khoom, ntau lub tuam txhab silicones ua lag luam hauv Suav teb muaj cov haujlwm txuas ntxiv lossis cov phiaj xwm tshiab.Lub peev xwm tsim tawm tshiab yuav yog qhov tseem ceeb hauv kev tsim tawm los ntawm 2022 txog 2023, thiab kev lag luam kev tsim khoom muaj peev xwm yuav nkag mus rau lub voj voog nrawm nrawm.

Raws li cov ntaub ntawv los ntawm Baichuan Yingfu, cov tuam txhab xws li Hesheng Silicon Industry, Yunnan Energy Investment, thiab Dongyue Silicon Materials yuav nqis peev kwv yees li ntawm 1.025 lab tons ntawm cov khoom siv silicones xyoo no.Cov tuam txhab xws li Tshiab Tshwj Xeeb Zog, Asia Silicon Kev Lag Luam, thiab Sichuan Yongxiang tseem tab tom nqis peev hauv polycrystalline silicon muaj peev xwm ntau lawm, tsav kev nce hauv kev lag luam silicones thov.

SAGSI kwv yees tias Tuam Tshoj lub peev xwm tsim tau ntawm silicones methyl monomers yuav tshaj 6 lab tons / xyoo los ntawm 2025, suav txog ntau dua 70% ntawm lub ntiaj teb no muaj peev xwm ntawm silicones methyl monomers.

Raws li C&EN, Momentive, lub tuam txhab ua lag luam silicones txawv teb chaws npaj yuav kaw nws cov khoom siv silicones hauv Waterford, New York, ua Dow tsuas yog cov chaw tsim khoom ntawm silicones upstream raw khoom hauv Tebchaws Meskas.

Lub ntiaj teb no silicones monomer muaj peev xwm raug xa mus rau Tuam Tshoj, thiab kev lag luam concentration piv yuav txuas ntxiv txhim kho yav tom ntej.

Sib sib zog nqus ua ntawm silicones

Cov khoom lag luam sib sib zog nqus silicones feem ntau muaj nyob rau hauv daim ntawv molecular ntawm RnSiX (4-n), thiab ruaj khov physicochemical zog ntawm silicon saw thiab qhov sib txawv ntawm cov pab pawg ua haujlwm tau txais cov khoom siv sib sib zog nqus silicones nrog kev siv nplua nuj.Cov khoom tseem ceeb yog silicone roj hmab thiab silicone roj, accounting rau 66% thiab 21% feem.

Tam sim no, kev lag luam sib sib zog nqus ntawm silicones tseem nyob rau theem kev loj hlob sai, nrog kev lag luam tawg.Muaj ntau tshaj 3,000 downstream sib sib zog nqus ua lag luam tsuas yog koom nrog silicone ua.
