NgoJanuwari 2023, ngenxa “yokulindela okuqinile” kanye nokugcinwa nokubambezeleka kochungechunge lwamadivayisi asekhaya, ukuphela kwentengo, yize isidingo siphansi, kodwa intengo yemakethe iqinile kancane. Ngemuva koMkhosi waseNtwasahlobo, ukuphela kwentengo akukathuthuki, futhi imakethe ye-styrene yasekhaya ibuthakathaka futhi iyashintshashintsha. Ngemuva kweholide likaMeyi, imakethe ye-styrene yasekhaya yaphinde yaba buthaka ngemva kokuphazamiseka, futhi yehla ngaphansi kophawu “lwezinkulungwane ezingu-8″ maphakathi noMeyi, futhi yaqhubeka nokwehla. Imakethe ye-styrene yaseMpumalanga China kusukela ekuqaleni konyaka ingu-8400 yuan/ton, yehla yaya ku-7360 yuan/ton yamanje, ukwehla okungu-12.38%.

Kusukela ekuqaleni kuka-2023, ukuphela kwentengo ye-styrene kanye nezinto zokusetshenziswa eziluhlaza kwe-benzene emsulwa kubonise ukuthambekela "kokuqala okubanzi bese kuba mncane", umehluko wentengo omaphakathi phakathi kwe-styrene kanye ne-benzene emsulwa wawungu-1349 yuan/ton, ukwanda ngo-17.20% esikhathini esifanayo ngonyaka odlule, kanti inzuzo emaphakathi yamadivayisi angahlanganisiwe e-styrene yayicishe ibe yi--28 yuan/ton, ukwanda okuhambisanayo okungu-92.86% esikhathini esifanayo ngonyaka odlule. Nakuba intengo ye-styrene kanye ne-benzene emsulwa ngo-2023 yehle ngokuvumelanisa uma iqhathaniswa nesikhathi esifanayo ngonyaka odlule, kodwa ingxenye yonyaka uhlelo lokufaka i-styrene, ukulungiswa kwangaphandle kuvame kakhulu, isigaba semakethe savela iphethini "yokuphakelwa kanye nesidingo sokulinganisela okuqinile", futhi ohlangothini lwezinto zokusetshenziswa ze-benzene emsulwa kunesisekelo "senzuzo ephezulu", umehluko wentengo phakathi kwalezi ezimbili usesigabeni esiphezulu. Ngaphansi komjikelezo omkhulu wokukhiqiza we-styrene, ukuphikisana phakathi kokunikezwa kanye nesidingo kuyaqhubeka nokukhula, futhi inzuzo yamadivayisi angahlanganisiwe e-styrene iyaqhubeka nokulungiswa, ukuphela kwezinto zokusetshenziswa akukwazi ukunikeza i-styrene ukwesekwa okuqinile kwezindleko.

Ukuphikisana phakathi kokunikezwa kanye nesidingo kuyaqina: i-styrene ikhula ngokushesha, futhi isidingo sinqunyelwe.

Esikhathini esifushane, i-styrene kwikota yesithathu isesebangeni lokukhula okukhulu kwamandla nomkhiqizo, futhi idatha ikhombisa ukuthi ukwanda okusha kwedivayisi eseceleni kokunikezwa kuzoba kukhulu kunokwanda okusha kwedivayisi eseceleni kokufuneka. Njengamanje, umbono wezindaba ojwayelekile, i-styrene kanye nokwehla engxenyeni yesibili yonyaka, yize kuthintekile izinguquko ekukhiqizweni nasekutholeni imali engenayo, amasethi amaningi amadivayisi azobambezeleka, okuhlinzeka ngezinguquko ezinkulu zokwanda kokunikezwa nesidingo se-styrene, kodwa njengoba amadivayisi amasha efakwa ekukhiqizweni, kulindeleke ukunikezwa okwengeziwe kwe-styrene kwikota yesithathu, futhi ukunikezwa kwemakethe kanye nesidingo esizini yokushisa ephezulu ngoJulayi nango-Agasti kubuthakathaka. Imakethe yanciphisa ukwanda kwasekuqaleni futhi yalungisa isakhiwo sokunikezwa kanye nesidingo ngemuva kokuba idivayisi entsha ingene emakethe, ibekwe ukuze kugwenywe amazinga okushisa aphezulu ngaphandle kwesizini, futhi imakethe yehla. Ngo-Agasti noma kwaqala ukukhula, isizini yendabuko yokukhiqiza "igolide lesishiyagalolunye lesiliva leshumi" iyaqhubeka nokunikeza imakethe indawo yokwenyuka kwentengo, iyonke, ikota yesithathu yemakethe yasekhaya ye-styrene noma "imakethe ye-weak after strength enamandla", imakethe ye-styrene isasekelwe ezindleleni kanye nokutholakala kanye nesidingo semigqa emibili eyinhloko yomthelela.
