Ngo-2023, onke amashishini e-China ye-styryl-ABS-PS-EPS ye-industry chain ingene kwinqanaba lomjikelo wokugqithiswa, ukusuka kwindawo yokujonga umthamo omtsha, i-styrene kunye ne-ABS zihamba phambili ekukhuleni konyaka nonyaka, ngokulandelanayo ngama-21. I-% kunye ne-41%, kodwa izinga lokukhula kwicala lemfuno liyacotha, nto leyo ekhokelela ekucuthekeni kwemida yenzuzo eqhubekayo kumashishini ahlukeneyo kwikhonkco loshishino. Ngokukodwa, inzuzo ye-ABS kunye ne-PS yehla kakhulu unyaka nonyaka, kunye noluhlu malunga ne-90%. Amandla oshishino lwekhonkco lweshishini ukuqhubeka nokwandisa umkhwa, kodwa icala lemfuno kunzima ukuba nenqanaba elitsha lokukhula, onke amashishini aya kujongana nemeko embi yonikezelo kunye nemfuno engafaniyo, ukwehla okukhulu kunye nokuncipha kweshishini kunye nezinye izinto ezimbi, ukusebenza kweshishini. uxinzelelo lonyuke kakhulu.

Ngo-2023, ukuveliswa kwe-styrene kunye nokusetyenziswa kwe-styrene kuqhubekile ukukhula ngemveliso emithathu esezantsi.

Ukusukela ngo-2019 ukuya ku-2023, inqanaba lokukhula elihlanganisiweyo lemveliso ye-styrene yaseTshayina laliyi-16.05%, libonisa ukunyuka okuthe gqolo unyaka nonyaka, kwaye ukusuka ngo-2020 ukuya kowama-2022, imveliso yayikwimeko yokunyuka okuphezulu, ngokunyuka okuphakathi konyaka malunga ne-1.63 yezigidi. iitoni. Ngo-2023, kunye nomjikelo omtsha wexesha lokudubula kwamandla emveliso, imveliso ye-styrene yaphinda yanda ukuya kwi-2 yezigidi zeetoni apha enyakeni. Ukuqala ngo-2021, imeko ye-styrene overcapacity yasekhaya ibonakaliswe ngokuthe ngcembe, kwaye ngokungeniswa komthamo omtsha, ukusetyenziswa kwamandla kuye kwacinezelwa ngakumbi. Ngo-2023, ngenxa yemveliso esembindini yezityalo ezisezantsi, kukho ukwanda okukhulu kwemfuno, ezinzisa ukuqala kofakelo olutsha.

Ukusukela ngo-2019 ukuya ku-2023, ukusetyenziswa kwe-styrene yaseTshayina kubonise ukonyuka komnyaka nonyaka, kunye nesantya sokukhula sonyaka se-7.89% kule minyaka mihlanu idlulileyo, kwaye ukusetyenziswa kwe-styrene kufikelele kwi-16.03 yezigidi zeetoni ngo-2023, ukonyuka kwe-13.66% xa kuthelekiswa no-2022. Ukususela ngo-2019 ukuya ku-2021, ngenxa yenzuzo ephantsi ye-styrene, ukuguquguquka kwexabiso le-styrene akuzange kube nempembelelo ebalulekileyo ekusetyenzisweni kwe-styrene. Ngo-2022, inzuzo epheleleyo yetsheyini loshishino lwe-styrene iya kunyukela phezulu, kwaye imveliso ye-styrene kunye ne-downstream iya kungena ngokuthe ngcembe kwilahleko, okukhokelela ekusetyenzisweni okuncinci kwe-styrene. Ngo-2023, nangona inzuzo yemveliso esezantsi ayilungile, kodwa phantsi koxinzelelo lokukhuphisana kwemveliso egxininisiweyo, umzi-mveliso osezantsi ukwimeko yokunyanzelisa imveliso, kwangaxeshanye, imfuno yokugcina inomsebenzi ongcono, ngokusisiseko. yetyise ukonyuswa kwemveliso esezantsi, kwaye ekugqibeleni ikhokelele ekwenyukeni okucacileyo kwemfuno ye-styrene apha enyakeni.

二.Ngo-2024, imveliso esezantsi ye-styrene "iqhubela phambili", kwaye uxinzelelo lwe-industrial chain luyehla!

Ngo-2024, ukubonelela nge-styrene kunye nemfuno kulindeleke ukuba iqhubeke nokubonisa ukukhula. Ngokutsho koqikelelo lwedatha ye-Longzhong, ngokwembono yesicwangciso esitsha sotyalo-mali lwezixhobo ze-styrene kwi-2024, iseti enye yezixhobo ezitsha ze-styrene kwisiqingatha sesibini sonyaka odlulileyo, oko kukuthi, i-600,000 yeetoni / isixhobo sonyaka we-Shandong Jingbo Petrochemical. ekuqaleni kulindeleke ukuba iqalise ukusebenza ngoMatshi ukuya ku-Epreli, kunye ne-450,000 yeetoni/ngonyaka isixhobo se-POSM se-Shenghong yokuRefining kunye ne-Chemical ecetywa ukuba iqalise ukusebenza kwisiqingatha sesibini sonyaka, iyonke ye-1.05 yezigidi zeetoni/ngonyaka. Xa kuthelekiswa no-2023, umthamo wonyaka wemveliso kulindeleke ukuba wehle nge-71.62%, kwaye ukunyuka kwe-styrene kulinganiselwe unyaka wonke. Ezantsi, utyalo-mali olulindelekileyo lwangoku, i-EPS ilindeleke ukuba ibe ne-1 yezigidi zeetoni / ngonyaka wesicwangciso esitsha somthamo wesixhobo sangaphambi kotyalo-mali, i-PS ine-1.25 yezigidi zeetoni / ngonyaka wesixhobo esitsha sesicwangciso sotyalo-mali, i-ABS inezigidi ezi-2 zeetoni / ngonyaka. yesicwangciso esitsha somthamo wesixhobo esiphambi kotyalo-mali.

Ukushwankathela: Ngo-2023, imveliso esezantsi ye-styrene ibonakala, kwaye imfuno yanda kakhulu, ezinzisa ukuqala kwezixhobo ezitsha ze-styrene. Nangona amandla emveliso ye-styrene esezantsi anyukile apha enyakeni, kodwa ukunqongophala kwemfuno elandelwayo kukhokelele ekwehleni kokusetyenziswa komthamo wemveliso, kodwa ngophuhliso lwemarike, kulindeleke ukuba amandla emveliso entsha ye-styrene kwimveliso ephantsi. I-2024 iphantsi kunokonyuka okuphambili kwezantsi, kwaye imeko yokubonelela ngokukhululeka kunye nemfuno ye-styrene ngo-2024 iya kuncitshiswa.
