Styrene yog ib qho tseem ceeb ua kua tshuaj raw khoom.Nws yog monocyclic aromatic hydrocarbon nrog alkene sab saw thiab tsim conjugate system nrog benzene nplhaib.Nws yog tus tswv cuab yooj yim tshaj plaws thiab tseem ceeb tshaj plaws ntawm unsaturated aromatic hydrocarbons.Styrene yog dav siv los ua raw khoom rau zus tau tej cov hluavtaws resins thiab roj hmab.
Styrene yog ib qho tseem ceeb ntawm cov kua tshuaj raw cov ntaub ntawv, teej tug mus rau ib tug monocyclic aromatic hydrocarbon nrog alkene sab saw thiab tsim ib tug conjugated system nrog benzene nplhaib.Nws yog unsaturated aromatic hydrocarbon styrene "cov kabmob roj thee thiab txuas roj hmab thiab yas", thiab nws yog ib qho tseem ceeb ntawm cov organic raw khoom rau kev lag luam petrochemical.Cov dej ntws ncaj qha ntawm styrene yog benzene thiab ethylene, thiab cov dej ntws ntws tawm kuj tseem tawg.Cov khoom tseem ceeb uas koom nrog yog foaming polystyrene, polystyrene, ABS resin, hluavtaws roj hmab, unsaturated polyester resin thiab styrene copolymer, thiab lub davhlau ya nyob twg yog tsuas yog siv nyob rau hauv cov khoom yas thiab hluavtaws roj hmab.
2010 ntiaj teb styrene ntau lawm muaj peev xwm nthuav, sharply thaum nce li ntawm 2.78 lab tons ntawm kev tsim muaj peev xwm, kev loj hlob ntawm productivity yog ze li ntawm 10%, feem ntau yog lub ntiaj teb no tshwj xeeb tshaj yog nyob rau hauv Tuam Tshoj mus rau downstream cov khoom ntawm styrene (terminal siv nyob rau hauv tsev cov khoom, tsheb thiab lub tsev cov ntaub ntawv industries) noj, uas nyob rau hauv 2009 thiab 2010, Tuam Tshoj qhov kev thov rau styrene yog siab tshaj 15%.Tom qab xyoo 2010, qhov kev loj hlob ntawm lub ntiaj teb styrene muaj peev xwm maj mam qeeb, thiab thaum kawg ntawm 2017, lub ntiaj teb styrene ntau lawm muaj peev xwm mus txog 33.724 lab tons.
Lub ntiaj teb lub peev xwm tsim khoom styrene feem ntau yog nyob rau sab hnub tuaj Asia, North America thiab Western Europe, uas suav txog 78.9% ntawm lub ntiaj teb styrene ntau lawm.Tsis tas li ntawd, thaj av Asia-Pacific suav txog 52 feem pua ntawm lub ntiaj teb cov khoom tsim tawm styrene.
Qhov kev thov qis qis rau styrene yog qhov sib txawv, thiab cov khoom kawg yog cov khoom siv yas thiab cov roj hmab hluavtaws.
Los ntawm thoob ntiaj teb kev xav tau ntawm styrene hauv xyoo 2016, 37.8% styrene yog siv rau polystyrene, 22.1% rau foaming polystyrene, 15.9% rau ABS resin, 9.9% rau styrene butadiene roj hmab, 4.8% rau unsaturated resin, thiab lwm yam.
Nrog rau kev nce ntawm cov peev txheej tshiab hauv tsev, Tuam Tshoj tus styrene ntshuam ntim thiab kev tuaj yeem tuaj yeem tau poob qis tsis tu ncua nyob rau xyoo tas los no.
Raws li cov ntaub ntawv kev lis kev cai, nyob rau hauv 2018, Tuam Tshoj tus loj styrene ntshuam lub teb chaws yog Saudi Arabia, Nyiv, Kaus Lim Qab Teb, Singapore, thiab lwm yam. Ua ntej 2017, cov khoom loj ntawm styrene ntshuam yog South Kauslim, Saudi Arabia thiab Tebchaws Meskas, nrog rau Kaus Lim Qab Teb. qhov loj tshaj plaws ntawm imports.
Txij li thaum Lub Rau Hli 23, 2018, Ministry of Commerce ntawm Tuam Tshoj tau tshaj tawm cov dej num tiv thaiv kev lag luam xws li 3.8% mus rau 55.7% ntawm styrene tuaj ntawm Republic of Kauslim thiab Tebchaws Meskas rau lub sijhawm tsib xyoos, ua rau muaj kev txo qis hauv kev lag luam. qhov kev faib ua feem ntawm Tuam Tshoj tus imports los ntawm lub koom pheej ntawm Kauslim nyob rau hauv lub thib ob ib nrab ntawm 2018, nrog Saudi Arabia thiab Nyiv yog lub ntsiab lub teb chaws ntawm imports.
Nrog rau kev tsim cov khoom siv hauv tsev ntiav, ntau lub peev xwm tsim tawm tshiab ntawm styrene yuav muab tso rau hauv kev ua haujlwm hauv Suav teb yav tom ntej.
Thaum lub sijhawm "13th Tsib Xyoo Plan", Tuam Tshoj tau txiav txim siab txhawb kev tsim kho hauv tsev thiab kev sib koom ua lag luam petrochemical.Tam sim no, Hengli, Sheng thiab lwm kaum lab qib refining thiab petrochemical kev sib koom ua ke tau pom zoo kom nkag mus rau lub sijhawm tsim kho, thiab cov tuam txhab loj tshaj plaws thiab cov lag luam petrochemical txhawb cov khoom siv hauv qab styrene.
