Ngo-2023, ukusebenza kwengeniso yeshishini eliphambili le-butadiene esezantsi kwenyuka emva koko kwawa, kwaye inzuzo yekhonkco yeshishini ngokuthe ngcembe idluliselwe kumantla emva kukaSeptemba. Ngokweemveliso eziqhelekileyo zemveliso ephezulu kunye nezantsi kunye nommeli oyintloko wedatha yexabiso lemarike, inzuzo yoshishino lwe-ABS yaqhubeka ijika emva kuka-Agasti, kwaye uluhlu lwaqhubeka lunzulu. Inzuzo yoshishino lwerabha yokwenziwa yagqiba urhulumente onenzuzo ephezulu ukususela ngoJuni, kwaye yawela kwindawo ephantsi ngoNovemba.

Ukuchatshazelwa luxinzelelo oluqhubekayo kwinzuzo esezantsi, izinga lokusetyenziswa kwamandla kumashishini aphambili e-butadiene ezantsi liye lehla kancinci. Izinga lokusetyenziswa kwamandla erubha ye-butadiene ngoNovemba liqikelelwe kwi-68.23%, phantsi kweepesenti ze-7.82 zeepesenti ukusuka kwinyanga edlulileyo. izinga lokusetyenziswa kwamandla kwishishini le-SBS kwi-43.86%, phantsi kwe-12.97 yepesenti yeepesenti; Izinga lokusetyenziswa kwamandla kwishishini le-ABS lalingama-74.90%, phantsi kwe-4.80 yepesenti yamanqaku ukusuka kwinyanga edlulileyo, ngelixa igcina indlela ehlayo ukususela ngo-Agasti.

Ngenxa yoxinzelelo kwiinzuzo eziphambili ezisezantsi zebutadiene, kunye nokuhla kancinci kwinqanaba lokusetyenziswa kwamandla kwishishini, ukusetyenziswa kwe-butadiene ekrwada kwishishini elisezantsi kwehlile. NgoNovemba, ukusetyenziswa kwe-butadiene kwishishini eliphambili elisezantsi liqikelelwa kwiitoni ze-298,700, phantsi kwe-8.29% ukusuka kwinyanga edlulileyo.

Ukusukela ngoNovemba, imarike yendawo ye-butadiene yaseTshayina igcine imeko eqhubekayo yokunyuka kangangeenyanga ezintlanu, ichatshazelwa yimfuno yokugcina kunye neendaba zayo ezisisiseko, imeko yentengiso yamashishini asezantsi aqhuba kancinci kancinci phantsi koxinzelelo, ulwahlulo oluphezulu kunye nolusezantsi lomlambo, ukusasazeka kwexabiso. emxinwa, echaphazela ingeniso esezantsi, ulwakhiwo kunye nezinye iindlela zokuhla. NgoDisemba, ngakolunye uhlangothi, imeko efunekayo ukuba imeko yangoku yemfuno ebuthathaka ingatshintshwa ayikho into "yokunika inzala kwi-downstream" ukukhuthaza imfuno. Ngakolunye uhlangothi, ngaba icandelo lokubonelela ngemarike ye-butadiene liqhubeka nemeko eqinile kwinqanaba lokuqala? Ukonyuka kwemveliso okuchatshazelwa kuqalwa ngokutsha kwesixhobo sogcino kwangethuba kunye nokunyuka kwempahla ethunyelwa kumazwe angaphandle okubangelwa lixabiso eliphantsi leediski zangaphandle zifanelwe ingqwalasela eqhubekayo.
