Ngo-2023, zonke izimboni eketangeni lemboni ye-styryl-ABS-PS-EPS yaseShayina zingene esigabeni somjikelezo wokunikezwa ngokweqile, ngokombono wamandla amasha, i-styrene ne-ABS zihamba phambili ekukhuleni konyaka nonyaka, ngokulandelana ngo-21% no-41%, kodwa izinga lokukhula kohlangothi lwesidingo lihamba kancane, okuholela ekuncipheni okuqhubekayo kwenzuzo yezimboni ezahlukahlukene eketangeni lemboni. Ikakhulukazi, inzuzo ye-ABS ne-PS yehla kakhulu unyaka nonyaka, ngobubanzi obungaba ngu-90%. Amandla emboni yeketangeni lezimboni ukuqhubeka nokwandisa lo mkhuba, kodwa uhlangothi lwesidingo kunzima ukuba nephuzu elisha lokukhula, zonke izimboni zizobhekana nesimo esibi sokungalingani kokuhlinzekwa kanye nesidingo, ukwehla okukhulu kanye nokukhula kwemboni nezinye izici ezimbi, ingcindezi yokusebenza kwemboni yanda kakhulu.

Ngo-2023, ukukhiqizwa kwe-styrene nokusetshenziswa kwe-styrene kwaqhubeka nokukhula ngokukhiqiza okuthathu okuseceleni komfula.

Kusukela ngo-2019 kuya ku-2023, izinga lokukhula kwe-compound lokukhiqizwa kwe-styrene yaseShayina lalingu-16.05%, okubonisa ukukhula okuqhubekayo unyaka nonyaka, kanti kusukela ngo-2020-2022, ukukhiqizwa kwakusesimeni sokwanda okuphezulu, kanye nokwanda okumaphakathi konyaka okungaba ngamathani ayizigidi eziyi-1.63. Ngo-2023, ngesikhathi sokuqhuma kwamandla okukhiqiza, ukukhiqizwa kwe-styrene kwaphinde kwanda kwafinyelela ngaphezu kwamathani ayizigidi ezimbili phakathi nonyaka. Kusukela ngo-2021, isimo sokwanda kwamandla e-styrene yasekhaya siye sabonakala kancane kancane, futhi ngokwethulwa kwamandla amasha, ukusetshenziswa kwamandla kuye kwacindezelwa kakhulu. Ngo-2023, ngenxa yokukhiqizwa okuphakathi kwezitshalo ezingezansi, kukhona ukwanda okukhulu kwesidingo, okuqinisa ukuqala kokufakwa okusha.

Kusukela ngo-2019 kuya ku-2023, ukusetshenziswa kwe-styrene eShayina kubonise ukuthambekela okwandayo unyaka nonyaka, ngesilinganiso sokukhula esihlanganisiwe sonyaka esingu-7.89% eminyakeni emihlanu edlule, kanti ukusetshenziswa kwe-styrene kufinyelele kumathani ayizigidi ezingu-16.03 ngo-2023, ukwanda ngo-13.66% uma kuqhathaniswa no-2022. Kusukela ngo-2019 kuya ku-2021, ngenxa yenzuzo enhle ye-styrene engezansi, ukuguquguquka kwentengo ye-styrene akuzange kube nomthelela omkhulu ekusetshenzisweni kwe-styrene. Ngo-2022, inzuzo iyonke yochungechunge lwemboni ye-styrene izoshintsha iye phezulu, futhi i-styrene kanye nemikhiqizo engezansi izolahlekelwa kancane kancane, okuholela ekusetshenzisweni kwe-styrene okulinganiselwe okuqhubekayo. Ngo-2023, noma ngabe inzuzo yokukhiqiza engezansi isengakabi yinhle, kodwa ngaphansi kwengcindezi yokuncintisana yokukhiqiza okugxilile, ifektri engezansi isesimweni sokugcizelela ekukhiqizeni, ngesikhathi esifanayo, isidingo sokugcina naso sisebenza kangcono, ngokuyisisekelo sigaya ukwanda komkhiqizo ophelele ongezansi, futhi ekugcineni kuholele ekwandeni okusobala kwesidingo se-styrene phakathi nonyaka.

Ngo-2024, ukukhiqizwa kwe-styrene okuphansi “kuya phambili”, futhi ingcindezi yochungechunge lwezimboni iyehla!

Ngo-2024, ukunikezwa kanye nesidingo se-styrene kulindeleke ukuthi kuqhubeke nokubonisa ukukhula. Ngokusho kwezilinganiso zedatha yeLongzhong, ngokombono wohlelo olusha lokutshalwa kwezimali lwemishini ye-styrene ngo-2024, isethi eyodwa yemishini emisha ye-styrene engxenyeni yesibili yonyaka odlule, okungukuthi, idivayisi yamathani angu-600,000 ngonyaka ye-Shandong Jingbo Petrochemical okulindeleke ukuthi iqale ukusebenza ngoMashi kuya ku-Ephreli, kanye nedivayisi ye-POSM yamathani angu-450,000 ngonyaka ye-Shenghong Refining and Chemical okulindeleke ukuthi iqale ukusebenza engxenyeni yesibili yonyaka, isamba samathani ayizigidi ezingu-1.05 ngonyaka. Uma kuqhathaniswa no-2023, amandla okukhiqiza wonyaka kulindeleke ukuthi ehle ngo-71.62%, kanti ukwanda kwe-styrene kunqunyelwe unyaka wonke. Ngaphansi, utshalomali olulindelekile lwamanje, i-EPS kulindeleke ukuthi ibe namathani ayisigidi esingu-1 ngonyaka wohlelo lwangaphambi kokutshalwa kwezimali lwamadivayisi amasha, i-PS inohlelo lwangaphambi kokutshalwa kwezimali lwamadivayisi amasha oluyizigidi ezingu-1.25 ngonyaka, i-ABS inohlelo lwangaphambi kokutshalwa kwezimali lwamadivayisi amasha oluyizigidi ezingu-2 ngonyaka.

Ngamafuphi: Ngo-2023, ukukhiqizwa kwe-styrene okuphansi kuyavela, futhi isidingo sanda kakhulu, okuqinisa ukuqala kwemishini emisha ye-styrene. Nakuba amandla amakhulu okukhiqiza i-styrene aphansi anda phakathi nonyaka, kodwa ukuntuleka kwesidingo sokugcina sokulandelela kwaholela ekwehleni kokusetshenziswa kwamandla omkhiqizo, kodwa ngokuthuthuka kwemakethe, kulindeleke ukuthi amandla amasha okukhiqiza i-styrene ngo-2024 aphansi kunokwanda okukhulu okuphansi, futhi isimo sokuhlinzekwa okukhululekile kanye nesidingo se-styrene ngo-2024 sizoncishiswa.
