Txij li cov khaub ncaws dai rau hauv cov khw ntxuav khaub ncaws qhuav ntawm txoj kev mus rau cov khoom siv raug ntxuav hauv cov chaw kho tsheb, perchloroethylene, ua cov tshuaj chlorinated hydrocarbon ua haujlwm tau zoo, tau pab cov lag luam kev lag luam tau zoo rau yuav luag ib puas xyoo. Txawm li cas los xij, nrog rau kev cai lij choj ib puag ncig thoob ntiaj teb thiab kev txhim kho kev lag luam sai dua, cov tshuaj no hu ua "King of Dry Cleaning" tam sim no sawv ntawm txoj kev hloov pauv. Txawm hais tias nws cov ntawv thov ib txwm muaj kev cov nyom, cov qib siab ntxiv xws li perchloroethylene qib hluav taws xob tab tom qhib qhov chaw loj hlob tshiab.
1. Txheej txheem cej luam ntawm cov khoom: Perchloroethylene yog dab tsi?
Perchloroethylene, tseem hu ua tetrachloroethylene, yog ib qho organic compound nrog cov mis molecular C₂Cl₄ thiab CAS No. 127-18-4. Nyob rau hauv qhov kub thiab txias ib txwm muaj, nws yog ib qho kua tsis muaj xim, pob tshab, ntws dawb nrog ib qho ntxhiab tsw zoo li ether thiab tsis kub hnyiab.
Cov Khoom Siv Lub Cev thiab Tshuaj

Perchloroethylene muaj peev xwm yaj tau zoo heev thiab ruaj khov tshuaj lom neeg siab. Nws tuaj yeem yaj ntau yam tshuaj xws li roj hmab, resin, rog, roj thiab tar; feem ntau cov resins hluavtaws yaj tau lossis o tuaj yeem hauv perchloroethylene. Perchloroethylene ntshiab tseem ruaj khov txawm tias thaum cua sov txog 500 ℃ tsis muaj cua, dej noo thiab cov tshuaj catalysts. Txawm li cas los xij, nws tuaj yeem raug oxidized hauv qab ultraviolet hluav taws xob los ua trichloroacetyl chloride thiab me ntsis phosgene, yog li me ntsis stabilizer feem ntau yog ntxiv rau cov khoom lag luam qib.
Perchloroethylene muaj ntau yam kev siv. Nws feem ntau yog siv ua cov organic solvent, dry cleaning agent thiab metal degreasing solvent. Nws kuj tseem ua haujlwm ua tshuaj anthelmintic, tshuaj extraction rog, tshuaj tua hluav taws thiab pa luam yeeb, thiab siv rau hauv kev tsim cov trichloroethylene thiab fluorine-muaj organic compounds.
2. Cov Kev Hloov Tshiab Tshiab: Kev Hloov Kho Txoj Cai thiab Kev Lag Luam Tshiab
2.1 Kev Lag Luam Thoob Ntiaj Teb: Kev Kho Kom Zoo Dua Thaum Muaj Kev Loj Hlob Ruaj Khoov
Raws li cov ntaub ntawv tshiab kawg los ntawm cov koom haum tshawb fawb kev ua lag luam, kev lag luam perchloroethylene thoob ntiaj teb loj hlob txog li USD 1.93 billion hauv xyoo 2025 thiab kwv yees tias yuav ncav cuag USD 2.53 billion los ntawm xyoo 2034, nrog rau kev loj hlob txhua xyoo (CAGR) ntawm 3.06% txij li xyoo 2026 txog 2034.
Kev ua lag luam perchloroethylene tab tom hloov pauv ntau yam. Ua ib qho tshuaj chlorinated uas siv dav dav, nws muaj nqis heev rau nws lub peev xwm yaj roj thiab tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam textile thiab automotive. Txawm li cas los xij, vim muaj kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv los ntawm nws cov pa phem volatile organic compound (VOC), kev ua lag luam tab tom ntsib kev tshuaj xyuas nruj dua.
2.2 Kev Nyuaj Siab Ib puag ncig: Los ntawm Kev Pheej Hmoo Kev Noj Qab Haus Huv mus rau Cov Cai Tswjfwm Nruj Dua
Cov teeb meem kev noj qab haus huv ntawm perchloroethylene tau rub kom muaj kev saib xyuas ntau ntxiv. Faib los ntawm Lub Koom Haum Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kab Mob Cancer (IARC) ua ib qhoPawg 2A carcinogen (tej zaum carcinogen rau tib neeg), perchloroethylene tau suav nrog hauv Suav tebDaim Ntawv Teev Cov Tshuaj Lom thiab Cov Tshuaj Phem Rau Dej (Pawg Thawj)thaum Lub Xya Hli 2019.
Cov kev cai lij choj thiab kev cai lij choj thoob ntiaj teb uas nruj zuj zus tab tom yuam cov chaw tsim khoom kom tsim cov kev xaiv uas muaj kev nyab xeeb dua thiab tsav kev lag luam mus rau kev txhim kho kom ruaj khov. Piv txwv li, cov tshuaj hydrocarbon solvents thiab cov txheej txheem hloov cov pa roj carbon dioxide tau maj mam txhawb nqa hauv kev lag luam ntxuav qhuav, ua rau kev thov perchloroethylene tsawg zuj zus hauv cov teb downstream ib txwm muaj. Kev nyiam nce ntxiv ntawm cov kev daws teeb meem ntxuav ib puag ncig tau cuam tshuam ncaj qha rau kev thov ua lag luam, vim tias kev tsom mus rau kev ruaj khov ntawm cov neeg siv khoom thiab cov lag luam ua rau kev tshawb fawb thiab kev txhim kho ntawm lwm cov tshuaj yaj.
3. Cov Qauv Kev Lag Luam: Kev Hloov Pauv Siab thiab Txoj Kev Txhim Kho Ntsuab
3.1 Cov Qauv Kev Xav Tau Sib Txawv: Kev Ntsws Ib Txwm Muaj vs Kev Nthuav Dav Siab
Kev lag luam perchloroethylene qhia tau tias muaj kev sib txawv ntawm cov qauv. Ntawm ib sab tes, cuam tshuam los ntawm cov khoom hloov pauv hauv kev lag luam ntxuav qhuav, qhov kev thov rau cov khoom siv perchloroethylene ib txwm muaj nyob rau hauv kev nyuaj siab, nrog rau kev kwv yees txhua xyoo ntawm kwv yees li 2.1% hauv xyoo tom ntej. Ntawm qhov tod tes, tsav los ntawm kev thov nce siab hauv kev tsim khoom semiconductor, kev lag luam perchloroethylene hluav taws xob qib tab tom nthuav dav ntawm CAGR ntawm kwv yees li 12.5%.
Piv txwv li, piv txwv li, Tuam Tshoj, feem ntawm kev ua lag luam ntawm cov khoom siv hluav taws xob perchloroethylene uas muaj cov khoom huv siab tau nce ntxiv los ntawm tsawg dua 5% mus rau 22%. Qee lub tuam txhab tsim khoom hauv tebchaws muaj peev xwm tsim cov khoom siv hluav taws xob 5N (99.999%), nkag mus rau hauv cov khoom siv semiconductor tau zoo. Feem ntawm kev ua lag luam ntawm cov khoom siv hauv tebchaws hauv 12-nti wafer fabs tau txog 39% hauv xyoo 2023.
Txoj kev hloov pauv no zoo ib yam li kev lag luam butyl acetate hauv xyoo tas los no: ob qho tib si ntsib kev nyuaj siab ntawm ib puag ncig, ob qho tib si nrhiav kev txhim kho qib siab thiab tshwj xeeb, thiab daws qhov kev thov qeeb hauv kev lag luam ib txwm muaj los ntawm kev nce tus nqi ntxiv ntawm cov khoom.
3.2 Kev Lag Luam Ib Ncigs: Kev Rov Siv Dua Los Ua Tus Tsav Tsheb Loj Hlob Tshiab
Vim muaj cov cai thiab cov kev cai ib puag ncig, tus qauv kev lag luam ncig rau perchloroethylene tau dhau los ua neeg laus zuj zus. Hauv Suav teb, cov khoom siv rov ua dua tshiab tau txog 31,000 tons hauv xyoo 2023 nrog rau tus nqi rov ua dua tshiab ntawm 58.3%. Tus nqi nkag mus ntawm cov khoom siv rov ua dua tshiab hauv kev ntxuav qhuav, khoom siv hluav taws xob thiab tshuaj lag luam yog 76.4% thiab 35% feem.
Los ntawm xyoo 2026, lub peev xwm rov ua dua tshiab ntawm perchloroethylene yuav nce mus txog 58,000 tons, suav txog 38% ntawm tag nrho cov khoom xa tuaj. Perchloroethylene rov ua dua tshiab tuaj yeem tswj tau qhov huv siab tshaj 99.8% thiab tuaj yeem hloov cov ntaub ntawv tshiab hauv ntau qhov xwm txheej siv, ua kom cov nqi tsim khoom zoo thiab txo cov teeb meem ib puag ncig.
3.3 Kev Hloov Pauv Ntsuab: Kev Tsim Kho Tshiab Txog Kev Siv Tshuab Ua Tus Thawj Coj Yav Tom Ntej
Vim muaj kev txwv ntawm ib puag ncig, cov chaw tsim khoom perchloroethylene tab tom nce kev nqis peev R&D los tsim cov kev daws teeb meem uas zoo rau ib puag ncig uas ua tau raws li cov qauv kev ua tau zoo thiab cov kev cai lij choj. Kev tsim khoom ntse thiab cov thev naus laus zis ntsuab xws li electrocatalytic chlorination yuav dhau los ua cov lus qhia tseem ceeb.
Ua raws li lub hom phiaj dual-carbon, kev lag luam perchloroethylene yuav tsum ua tiav lub hom phiaj theem ntawmTsis muaj kev loj hlob ntawm lub peev xwm tsim khoom tshiab thiab kev them tag nrho ntawm kev thov tshiab los ntawm cov khoom siv rov ua dua tshiabua ntej xyoo 2030. Kev ua lag luam yuav ua raws li qhov sib txawv ntawm kev loj hlob: tswj kev siv nyiaj ib txwm ruaj khov thaum tshawb nrhiav cov kev xaiv tshiab thiab ruaj khov uas hloov kho rau cov neeg siv khoom nyiam thiab cov cai tswjfwm.
Txij li thaum pib xyoo 2026, kev lag luam perchloroethylene hauv Suav teb tau tsim kom muaj kev sib tw ntau yam uas muaj cov tuam txhab loj loj uas muaj cov tshuaj chlor-alkali thiab cov chaw tsim tshuaj zoo. Kev lag luam CR5 (qhov sib piv ntawm tsib lub tuam txhab saum toj kawg nkaus) ncav cuag 68.5%. Cov nyiaj tau los tau sib txawv ntau dua: cov tuam txhab uas muaj peev xwm ua kom huv si, cov txheej txheem rov ua dua tshiab kaw thiab kev tswj hwm digital tuaj yeem tswj tau cov nyiaj tau los ntau dua 30%, thaum lub peev xwm qis yuav poob rau hauv kev poob.

Xaus lus
Txij li cov khw muag khoom qhuav mus rau cov chaw tsim khoom semiconductor, perchloroethylene nyob hauv txoj haujlwm tseem ceeb hauv kev lag luam niaj hnub no vim nws qhov kev ua tau zoo heev. Nyob rau hauv kev tsav tsheb ib puag ncig thoob ntiaj teb, kev lag luam perchloroethylene sawv ntawm qhov tig tseem ceeb. Cov tuam txhab uas ua tus thawj coj hauv kev rhuav tshem cov teeb meem kev ua kom huv si, tsim cov kab ke rov ua dua tshiab, thiab txais yuav kev tsim kho tshiab ntsuab yuav ntes tau cov cib fim zoo hauv kev hloov pauv kev lag luam tom ntej. Yav tom ntej ntawm perchloroethylene nyob ntawm seb kev lag luam ua li cas thiaj li sib npaug zoo ntawm kev ua tau zoo thiab lub luag haujlwm ib puag ncig - qhov kev sib tw uas tag nrho cov tshuaj lom neeg zoo ntsib.
