Ngowama-2025, ishishini le-styrene libonise umkhwa "wokwehla kokuqala emva koko ukubuyiselwa kwimeko yesiqhelo" phakathi kokudibana phakathi kokukhululwa komthamo oqinileyo kunye nokwahluka kwemfuno yesakhiwo. Njengoko uxinzelelo lwecala lokubonelela ngempahla luyehla kancinci, imiqondiso yokwehla kwemarike yaya icaca ngakumbi. Nangona kunjalo, ukungqubana kwesakhiwo phakathi kwezinto eziphezulu kunye nokwahluka kwemfuno kwahlala kungasombululwanga, nto leyo eyathintela indawo yokubuyela kwamaxabiso.
Uxinzelelo lomthamo kwicala lobonelelo yayiyeyona nto iphambili eyayinzima kwimarike kwisiqingatha sokuqala sonyaka. Ngo-2025, amandla amatsha emveliso ye-styrene yasekhaya aqala ukusebenza ngendlela edibeneyo, kunye namandla amatsha ongezelelweyo ngonyaka adlula iitoni ezi-2 zezigidi. Iiprojekthi ezinkulu zokucoca kunye nokudibanisa iikhemikhali ezifana neLiaoning Baolai kunye neZhejiang Petrochemical zibe negalelo ekwandeni okukhulu, ziqhuba ukukhula komthamo wonyaka we-18%. Ukukhululwa komthamo odibeneyo, kunye nemfuno yesiqhelo yexesha lokungabikho kwexesha kwikota yokuqala, kwenze ukuba ukungalingani kwemfuno yokubonelela ngemveliso kwimarike kube mandundu. Amaxabiso e-styrene aqhubeka ehla ukusuka kwi-8,200 yuan ngetoni ekuqaleni konyaka, efikelela kwi-6,800 yuan ngetoni ekupheleni kuka-Okthobha, emele ukwehla kwe-17% ukusuka ekuqaleni konyaka.
Emva kwesiqingatha sikaNovemba, imakethi iqhube i-rebound ephindwe kancinane, amaxabiso enyuka aya kwi-7,200 yuan ngetoni, ukunyuka okumalunga ne-6%, okubonisa ukuvela kokuqala kweempawu zokwehla. Ukwehla kwe-rebound kuqhutywe zizinto ezimbini eziphambili. Okokuqala, icala lokubonelela linciphile: iiseti ezintathu zezityalo ezinomthamo wonyaka we-1.2 yezigidi zeetoni eShandong, eJiangsu nakwezinye iindawo ziye zamisa imisebenzi okwethutyana ngenxa yokugcinwa kwezixhobo okanye ilahleko yenzuzo, nto leyo ehlisa izinga lokusebenza leveki ukusuka kwi-85% ukuya kwi-78%. Okwesibini, icala leendleko linike inkxaso: liqhutywa kukwehla kwexabiso leoyile yamazwe ngamazwe kunye nokwehla kweendawo zokugcina iimpahla, ixabiso le-benzene yokutya linyuke nge-5.2%, linyusa iindleko zemveliso ye-styrene. Nangona kunjalo, iindawo zokugcina iimpahla eziphezulu zahlala zingumqobo ophambili. Ekupheleni kukaNovemba, iindawo zokugcina iimpahla ze-styrene kumazibuko aseMpuma China zifikelele kwi-164,200 yeetoni, i-23% ephezulu kunexesha elifanayo kunyaka ophelileyo. Iintsuku zokutshintsha kwezinto ezikhoyo zahlala kwiintsuku ezili-12, zidlula kakhulu uluhlu olufanelekileyo lweentsuku ezi-8, zinciphisa ukunyuka kwamaxabiso okungakumbi.
Ipateni yemfuno eyahlukileyo iqinise ubunzima bemarike, nto leyo ekhokelele "ekusebenzeni okunemigangatho emibini" kumacandelo aphambili asezantsi. Ishishini le-ABS (Acrylonitrile-Butadiene-Styrene) livele njengelona libalaseleyo: lixhamla ekuthunyelweni kwamanye amazwe okwandayo kwezithuthi zamandla ezintsha kunye nezixhobo zasekhaya ezikrelekrele, imfuno yalo yonyaka inyuke nge-27.5% unyaka nonyaka. Abavelisi abakhulu be-ABS basekhaya bagcine izinga lokusebenza elingaphezulu kwe-90%, bevelisa imfuno yokuthengwa okuqhubekayo kwe-styrene. Ngokwahlukileyo koko, amashishini e-PS (Polystyrene) kunye ne-EPS (Expandable Polystyrene) athwaxwa yimfuno ecothayo, ethotywa bubuthathaka obuhlala ixesha elide kwimarike yezindlu. I-EPS isetyenziswa kakhulu kwizixhobo zokukhusela udonga lwangaphandle; ukwehla kwe-15% ngonyaka ekuqaleni kokwakhiwa kwezindlu ezintsha kubangele ukuba abavelisi be-EPS basebenze ngaphantsi kwe-50%. Okwangoku, abavelisi be-PS babone izinga labo lokusebenza lijikeleze malunga ne-60%, ngaphantsi kakhulu kwinqanaba lexesha elifanayo kunyaka ophelileyo, ngenxa yokukhula okucothayo kokuthunyelwa kwamanye amazwe kwamashishini okukhanya afana nokupakisha kunye nezinto zokudlala.
Okwangoku, imakethi ye-styrene ikwinqanaba elilinganayo elibonakaliswa "kukuncipha kokunikezelwa okubonelela ngokwahluka komgangatho kunye neemfuno ezithintela amandla okukhuphuka". Nangona iimpawu zokwehla ziye zavela, amandla okubuyela umva asalinde ukususwa kwempahla okusebenzayo kunye nokubuyiselwa kwemfuno epheleleyo. Ngexesha elifutshane, elithintelwe yimiqathango yokuthutha yasebusika kwiimveliso zeekhemikhali kunye nokuqaliswa kwakhona kwezinye izityalo zokugcina, imakethi kulindeleke ukuba itshintshe ngandlela thile. Ngexesha eliphakathi ukuya kwelide, kufuneka kunikwe ingqalelo kwimpembelelo ekhulayo yemigaqo-nkqubo yezindlu ezikhululekileyo kwimfuno ye-PS kunye ne-EPS, kunye nokwandiswa kwemfuno ye-ABS kwicandelo lokuvelisa elikumgangatho ophezulu. Ezi zinto ziya kumisela kunye ukuphakama kokubuya kwexabiso le-styrene.
