Ngowama-2023, onke amashishini kwishishini laseTshayina i-styryl-ABS-PS-EPS angene kwinqanaba lomjikelo wokunikezelwa ngokugqithisileyo, ngokwembono yamandla amatsha, i-styrene kunye ne-ABS ziphambili ekukhuleni konyaka nonyaka, ngokulandelelana ngama-21% kunye nama-41%, kodwa izinga lokukhula kwemfuno licotha, okubangela ukuncipha okuqhubekayo kwemida yenzuzo yamashishini ahlukeneyo kwishishini. Ngokukodwa, inzuzo ye-ABS kunye ne-PS yehla kakhulu unyaka nonyaka, malunga ne-90%. Amandla eshishini leshishini le-Industrial chain ukuqhubeka nokwandisa umkhwa, kodwa icala lemfuno kunzima ukuba nenqanaba elitsha lokukhula, onke amashishini aya kujongana nemeko embi yokungalingani kokunikezelwa kunye nemfuno, ukwehla okukhulu kunye nokunyuka kwemveliso kunye nezinye izinto ezimbi, uxinzelelo lokusebenza kweshishini lunyuke kakhulu.

Ngowama-2023, imveliso ye-styrene kunye nokusetyenziswa kwe-styrene kuqhubekile nokukhula ngemveliso emithathu esezantsi.

Ukususela ngo-2019 ukuya ku-2023, izinga lokukhula kwemveliso ye-styrene yaseTshayina yayiyi-16.05%, nto leyo ebonisa ukunyuka okuqhubekekayo unyaka nonyaka, kwaye ukususela ngo-2020-2022, imveliso yayikwimeko yokwanda okuphezulu, ngokomyinge wokwanda konyaka malunga neetoni eziyi-1.63 yezigidi. Ngo-2023, ngexesha lokuqhuma kwamandla emveliso, imveliso ye-styrene yanda kwakhona yaya kuthi ga kwiitoni ezingaphezu kwezigidi ezi-2 ngonyaka. Ukususela ngo-2021, imeko yomthamo we-styrene yasekhaya iye yabonakala kancinci kancinci, kwaye ngokungeniswa kwamandla amatsha, ukusetyenziswa kwamandla kuye kwancitshiswa ngakumbi. Ngo-2023, ngenxa yemveliso ephakathi yezityalo ezisezantsi, kukho ukwanda okukhulu kwemfuno, nto leyo ezinzisa ukuqala kokufakelwa okutsha.

Ukususela ngo-2019 ukuya ku-2023, ukusetyenziswa kwe-styrene eTshayina kubonise umkhwa okhulayo unyaka nonyaka, kunye nesantya sokukhula esidibeneyo sonyaka se-7.89% kwiminyaka emihlanu edlulileyo, kwaye ukusetyenziswa kwe-styrene kufikelele kwi-16.03 yezigidi zeetoni ngo-2023, ukunyuka kwe-13.66% xa kuthelekiswa no-2022. Ukususela ngo-2019 ukuya ku-2021, ngenxa yenzuzo entle ye-styrene esezantsi, ukuguquguquka kwamaxabiso e-styrene akuzange kube nefuthe elikhulu ekusetyenzisweni kwe-styrene. Ngo-2022, inzuzo iyonke yecandelo leshishini le-styrene iya kunyuka iye phezulu, kwaye i-styrene kunye neemveliso ezisezantsi ziya kungena kancinci kancinci kwiilahleko, nto leyo ekhokelela ekusetyenzisweni kwe-styrene okuncinci. Ngowama-2023, nokuba inzuzo yemveliso esezantsi ayikalungi, kodwa phantsi koxinzelelo lokhuphiswano lwemveliso eqokelelweyo, umzi-mveliso osezantsi ukwimeko yokugxininisa kwimveliso, kwangaxeshanye, imfuno yesiphelo nayo isebenza ngcono, ngokusisiseko yehlisa ukunyuka kwemveliso iyonke esezantsi, kwaye ekugqibeleni ikhokelele ekwandeni okucacileyo kwemfuno ye-styrene phakathi konyaka.

Ngowama-2024, imveliso ye-styrene esezantsi "iyanda", kwaye uxinzelelo lweshishini lemizi-mveliso luyehla!

Ngowama-2024, ukunikezelwa kwe-styrene kunye nemfuno kulindeleke ukuba kuqhubeke nokubonisa ukukhula. Ngokutsho koqikelelo lwedatha yaseLongzhong, ngokwembono yesicwangciso esitsha sotyalo-mali sezixhobo ze-styrene ngo-2024, iseti enye yezixhobo ezintsha ze-styrene kwisiqingatha sesibini sonyaka ophelileyo, oko kukuthi, isixhobo se-600,000 yeetoni ngonyaka seShandong Jingbo Petrochemical ekulindeleke ukuba siqale ukusebenza ngoMatshi ukuya ku-Epreli, kunye nesixhobo se-POSM se-Shenghong Refining and Chemical seetoni ezingama-450,000 ngonyaka esicetywayo ukuba siqale ukusebenza kwisiqingatha sesibini sonyaka, sisonke seetoni ezili-1.05 yezigidi ngonyaka. Xa kuthelekiswa nowama-2023, amandla emveliso yonyaka kulindeleke ukuba ehle nge-71.62%, kwaye ukunyuka kwe-styrene kunqunyelwe unyaka wonke. Ngaphantsi komlambo, utyalo-mali olulindelekileyo lwangoku, kulindeleke ukuba i-EPS ibe ne-1 yezigidi zeetoni ngonyaka zesicwangciso sangaphambi kokutyala imali esitsha sesixhobo, i-PS ine-1.25 yezigidi zeetoni ngonyaka zesicwangciso sangaphambi kokutyala imali esitsha sesixhobo, i-ABS ine-2 yezigidi zeetoni ngonyaka zesicwangciso sangaphambi kokutyala imali esitsha sesixhobo.

Ukushwankathela: Ngo-2023, imveliso ye-styrene esezantsi iyavela, kwaye imfuno iyanda kakhulu, nto leyo ezinzisa ukuqaliswa kwezixhobo ezintsha ze-styrene. Nangona amandla okuvelisa i-styrene asezantsi enyuka phakathi nonyaka, kodwa ukungabikho kwemfuno yokugcina yokulandelela kukhokelele ekwehleni kokusetyenziswa kwamandla emveliso, kodwa ngophuhliso lwemarike, kulindeleke ukuba amandla okuvelisa i-styrene entsha ngo-2024 angaphantsi kunokwanda okuphambili kwe-downstream, kwaye imeko yokunikezelwa okukhululekileyo kunye nemfuno ye-styrene ngo-2024 iya kuncipha.
