NgoJanuwari 2023, ngenxa “yokulindelwe okuqinile” nokugcinwa nokubambezeleka kochungechunge lwemishini yasekhaya, indawo iyaphela, nakuba isidingo singesihle, kodwa intengo yemakethe iqinile kancane. Ngemuva koMkhosi Wasentwasahlobo, ukuphela kwendawo akukathuthuki, futhi imakethe ye-styrene yasekhaya ibuthakathaka futhi iyaguquguquka. Ngemuva kweholide likaMeyi Day, imakethe yasekhaya ye-styrene iba buthakathaka futhi ngemva kwesimo esinzima, futhi yehla ngaphansi “kophawu lwezinkulungwane eziyisi-8” phakathi noMeyi, futhi yaqhubeka nokwehla. Imakethe ye-styrene yaseMpumalanga yeChina kusukela ekuqaleni konyaka ingu-8400 yuan/ton, yehle yafika ku-7360 yuan/ton yamanje, yehle ngo-12.38%.

Kusukela ekuqaleni kuka-2023, isiphetho se-styrene kanye nempahla eluhlaza yokusatshalaliswa kwentengo ye-benzene emsulwa kubonise inkambiso “yokuqala ebanzi bese ibe mncane”, umehluko wentengo omaphakathi phakathi kwe-styrene ne-benzene emsulwa ubungu-1349 yuan/ton, okuwukunyuka ngo-17.20% esikhathini esikhathini esifanayo ngonyaka odlule, futhi inzuzo evamile yamadivayisi angahlanganisiwe e-styrene yayicishe ibe -28 yuan/ton, ukukhuphuka okuvumelanayo kwe-92.86% esikhathini esifanayo ngonyaka odlule. Nakuba intengo ye-styrene ne-benzene ehlanzekile ngo-2023 yehla ngokuhambisanayo uma iqhathaniswa nesikhathi esifanayo ngonyaka odlule, kodwa ingxenye yonyaka uhlelo lokufakwa kwe-styrene, ukunakekelwa kwangaphandle kuvame kakhulu, isigaba semakethe sibonakale "sokunikezwayo nokufuna ibhalansi eqinile", futhi ohlangothini lwempahla eluhlaza ye-benzene ehlanzekile iyindawo "yenzuzo ephezulu", umehluko wentengo phakathi kwakho kokubili usezingeni eliphezulu. Ngaphansi komjikelezo omkhulu wokukhiqiza we-styrene, ukungqubuzana phakathi kokunikezwa nokufunwa kuyaqhubeka kwanda, futhi inzuzo yamadivayisi angahlanganisiwe e-styrene iyaqhubeka nokulungisa, ukuphela kwezinto ezibonakalayo akukwazi ukunikeza ukusekelwa kwezindleko eziqinile ze-styrene.

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

Esikhathini esifushane, i-styrene kwikota yesithathu isesebangeni lokwanda okukhulu komthamo nokuphumayo, futhi idatha ibonisa ukuthi ukukhuphuka okusha kwedivayisi yohlangothi lokunikezela kuzoba kukhulu kunokwenyuka okusha kwedivayisi eseceleni kwesidingo. Njengamanje, umbono wezindaba ovamile, i-styrene kanye nokwehla komfula engxenyeni yesibili yonyaka, nakuba kuthinteke izinguquko ekukhiqizeni nasekutholeni ukuthengiswa, amasethi amaningi wamadivayisi azobambezeleka, anikeze okuguquguqukayo okukhulu kokwanda kokunikezwa kwe-styrene kanye nesidingo, kodwa njengoba amathuluzi amasha afakwa ekukhiqizweni, kulindeleke ukutholakala okungeziwe kwe-styrene engxenyeni yesithathu, futhi ukunikezwa kwemakethe kanye nesidingo enkathini yokushisa ephezulu ngoJulayi no-Agasti kubuthakathaka. Imakethe igaye ukwenyuka kwangaphambi kwesikhathi futhi yahlela ukunikezwa nesakhiwo sokufunwa ngemuva kokuthi idivayisi entsha ingene emakethe, ibekwe phezulu ukuze igweme izinga lokushisa eliphezulu ngaphandle kwesizini, futhi imakethe yawa. Ngo-Agasti noma kwaqala ukukhula, "igolide eliyisishagalolunye isiliva eliyishumi" inkathi yokukhiqiza ephezulu yokukhiqiza iyaqhubeka nokunikeza imakethe indawo yokwenyuka kwamanani, sekukonke, ingxenye yesithathu yemakethe ye-styrene yasekhaya noma "isimo esibuthakathaka ngemuva kokuthambekela okuqinile", imakethe ye-styrene isasekelwe ezindlekweni nasekunikezeni kanye nesidingo semigqa emibili eyinhloko yomthelela.
