Ngo-2023, ukusebenza kwenzuzo iyonke embonini ye-butadiene eyinhloko engezansi kwenyuka kwabe sekwehla, kanti inzuzo yochungechunge lwezimboni yathuthela kancane kancane e-upstream ngemva kukaSepthemba. Ngokusho kwemikhiqizo eyinhloko yemikhiqizo engenhla nephansi kanye nedatha yentengo yemakethe eyinhloko emele, inzuzo yemboni ye-ABS yaqhubeka nokubuyela emuva ngemva kuka-Agasti, futhi ububanzi baqhubeka nokujula. Inzuzo yemboni yerabha yokwenziwa yaqeda isimo senzuzo ephezulu kusukela ngoJuni, futhi yehlela esimweni esiphansi ngoNovemba.

Ithintwe yingcindezi eqhubekayo yenzuzo engezansi, izinga lokusetshenziswa kwamandla ezimbonini ezinkulu ezingezansi ze-butadiene liye lehla kancane kancane. Izinga lokusetshenziswa kwamandla erabha ye-butadiene ngoNovemba lilinganiselwa ku-68.23%, lehle ngamaphesenti angu-7.82 kusukela ngenyanga edlule. Izinga lokusetshenziswa kwamandla embonini ye-SBS ku-43.86%, lehle ngamaphesenti angu-12.97; Izinga lokusetshenziswa kwamandla embonini ye-ABS lalingu-74.90%, lehle ngamaphesenti angu-4.80 kusukela ngenyanga edlule, ngenkathi kugcinwa umkhuba wokwehla kusukela ngo-Agasti.

Ngenxa yengcindezi enzuzweni eyinhloko ye-butadiene, kanye nokwehla kancane kancane kwesilinganiso sokusetshenziswa kwamandla embonini, ukusetshenziswa kwe-butadiene yezinto zokusetshenziswa embonini engezansi kwehlile. NgoNovemba, ukusetshenziswa kwe-butadiene embonini eyinhloko engezansi kulinganiselwa ku-298,700 amathani, kwehle ngo-8.29% kusukela ngenyanga edlule.

Kusukela ngoNovemba, imakethe ye-butadiene spot yaseShayina ibilokhu iqhubeka nokwenyuka okuqhubekayo izinyanga ezinhlanu, ithintwe yisidingo sokugcina kanye nezindaba zayo eziyisisekelo, ukuthambekela kwemakethe yezimboni ezinkulu ezingaphansi komfula kuye kwasebenza kancane kancane ngaphansi kwengcindezi, ukwehluka kwemikhuba engenhla nangezansi komfula, ukusabalala kwentengo kunciphile, kuthinta inzuzo engezansi komfula, ukwakhiwa kanye nokunye ukuthambekela okuwela phansi. NgoDisemba, ngakolunye uhlangothi, isimo esidingekayo sokuthi isimo samanje sesidingo esibuthakathaka singaguqulwa yini asilutho ngaphandle kokuthi "sinikeze inzalo kwabaphansi komfula" ukuze kukhuthazwe isidingo. Ngakolunye uhlangothi, ingabe uhlangothi lokuhlinzekwa kwemakethe ye-butadiene lungaqhubeka nesimo esiqinile esigabeni sokuqala? Ukwanda komkhiqizo okuthintwe ukuqala kabusha kwedivayisi yokulungisa kusenesikhathi kanye nokwanda kwezimpahla ezingeniswayo okubangelwa yintengo ephansi yamadiski angaphandle kufanele kuqashelwe njalo.
