Xyoo 2025, kev lag luam styrene tau pom tias muaj kev hloov pauv "thawj zaug poob qis ces mam li rov zoo" thaum muaj kev sib cuam tshuam ntawm kev tso tawm peev xwm ntau thiab kev sib txawv ntawm kev thov khoom. Thaum kev nyuaj siab ntawm sab kev muab khoom tau txo qis me ntsis, cov cim qhia tias kev lag luam poob qis tau pom tseeb dua. Txawm li cas los xij, qhov kev tsis sib haum xeeb ntawm cov khoom muaj ntau thiab kev sib txawv ntawm kev thov khoom tseem tsis tau daws, ua rau tsis muaj chaw rau kev rov qab los ntawm tus nqi.
Qhov kev poob siab ntawm sab kev muab khoom yog qhov tseem ceeb uas cuam tshuam rau kev ua lag luam hauv thawj ib nrab ntawm lub xyoo. Xyoo 2025, lub peev xwm tsim khoom styrene hauv tsev tshiab tau pib ua haujlwm ntau, nrog rau lub peev xwm tshiab ntxiv txhua xyoo tshaj 2 lab tons. Cov haujlwm loj hauv kev ua kom huv thiab kev sib koom ua ke tshuaj xws li Liaoning Baolai thiab Zhejiang Petrochemical tau pab txhawb rau qhov nce ntxiv loj, tsav tsheb kom muaj peev xwm loj hlob ntawm 18% txhua xyoo. Kev tso tawm lub peev xwm ntau, ua ke nrog lub caij tsis muaj kev thov hauv thawj peb lub hlis, ua rau kev tsis sib npaug ntawm kev muab khoom thiab kev thov hauv kev ua lag luam hnyav dua. Cov nqi styrene pheej poob qis los ntawm 8,200 yuan ib ton thaum pib ntawm lub xyoo, ntaus tus nqi qis tshaj plaws txhua xyoo ntawm 6,800 yuan ib ton thaum kawg ntawm lub Kaum Hli, sawv cev rau 17% poob qis los ntawm thaum pib ntawm lub xyoo.
Tom qab nruab nrab lub Kaum Ib Hlis, kev ua lag luam tau rov qab los ua ntu zus, nrog rau tus nqi nce mus txog li 7,200 yuan ib tuj, nce li ntawm 6%, cim qhov pib tshwm sim ntawm cov yam ntxwv qis tshaj plaws. Qhov rov qab los yog tsav los ntawm ob qho tseem ceeb. Ua ntej, sab khoom siv tau cog lus: peb pawg ntawm cov nroj tsuag nrog tag nrho cov peev xwm txhua xyoo ntawm 1.2 lab tons hauv Shandong, Jiangsu thiab lwm thaj chaw tau ncua kev ua haujlwm ib ntus vim yog kev saib xyuas cov khoom siv lossis kev poob nyiaj, rub tus nqi ua haujlwm txhua lub lim tiam los ntawm 85% mus rau 78%. Qhov thib ob, sab nqi tau muab kev txhawb nqa: tsav los ntawm kev rov qab los ntawm tus nqi roj thoob ntiaj teb thiab kev poob qis ntawm cov khoom muag hauv chaw nres nkoj, tus nqi ntawm cov khoom noj khoom haus benzene tau nce 5.2%, thawb tus nqi tsim khoom ntawm styrene. Txawm li cas los xij, cov khoom muag ntau tseem yog qhov tseem ceeb. Thaum kawg ntawm lub Kaum Ib Hlis, cov khoom muag styrene ntawm East China chaw nres nkoj tau txog 164,200 tons, siab dua 23% piv rau lub sijhawm tib yam xyoo tas los. Cov hnub hloov pauv khoom muag tau nyob ntawm 12 hnub, ntau dua qhov ntau ntawm 8 hnub, txwv tsis pub tus nqi nce ntxiv.
Tus qauv kev thov sib txawv tau ua rau kev ua lag luam nyuaj zuj zus, ua rau muaj "kev ua tau zoo ob theem" thoob plaws cov lag luam tseem ceeb. Kev lag luam ABS (Acrylonitrile-Butadiene-Styrene) tau tshwm sim ua qhov tseem ceeb tshaj plaws: tau txais txiaj ntsig los ntawm kev xa khoom ntawm cov tsheb fais fab tshiab thiab cov khoom siv hauv tsev ntse, nws qhov kev thov txhua xyoo tau nce 27.5% xyoo-rau-xyoo. Cov tuam txhab tsim khoom ABS hauv tsev loj tau tswj hwm tus nqi ua haujlwm ntau dua 90%, ua rau muaj kev thov khoom siv styrene ruaj khov. Hauv qhov sib txawv, PS (Polystyrene) thiab EPS (Expandable Polystyrene) kev lag luam raug kev txom nyem qeeb qeeb, rub los ntawm qhov tsis muaj zog ntev hauv kev ua lag luam vaj tsev. EPS feem ntau yog siv rau hauv cov ntaub ntawv rwb thaiv tsev phab ntsa sab nraud; qhov kev poob qis 15% xyoo-rau-xyoo hauv kev tsim kho vaj tsev tshiab pib ua rau cov neeg tsim khoom EPS ua haujlwm tsawg dua 50% peev xwm. Lub caij no, cov neeg tsim khoom PS pom lawv tus nqi ua haujlwm nyob ib puag ncig 60%, qis dua qib ntawm tib lub sijhawm xyoo tas los, vim yog kev loj hlob qeeb ntawm kev xa khoom ntawm cov lag luam teeb pom kev zoo xws li ntim khoom thiab cov khoom ua si.
Tam sim no, kev ua lag luam styrene nyob rau hauv theem sib npaug uas muaj tus cwj pwm los ntawm "kev cog lus ntawm kev muab khoom muab qhov sib txawv ntawm pem teb thiab kev thov uas txwv tsis pub muaj peev xwm nce siab". Txawm hais tias cov yam ntxwv qis tshaj plaws tau tshwm sim, lub zog rau kev thim rov qab tseem tos kev tshem tawm cov khoom muag thiab kev rov qab los ntawm kev thov tag nrho. Hauv lub sijhawm luv luv, txwv los ntawm kev txwv kev thauj mus los rau lub caij ntuj no ntawm cov khoom siv tshuaj thiab kev rov pib dua ntawm qee lub Hoobkas txij nkawm, kev ua lag luam yuav hloov pauv mus rau sab. Hauv nruab nrab mus rau lub sijhawm ntev, yuav tsum tau them sai sai rau qhov cuam tshuam ntawm cov cai tswjfwm vaj tse so rau PS thiab EPS kev thov, nrog rau kev nthuav dav ntawm kev thov ntawm ABS hauv kev lag luam tsim khoom siab. Cov yam ntxwv no yuav ua ke txiav txim siab qhov siab ntawm tus nqi styrene rov qab los.
