Kusukela ngo-2023, intengo yemakethe ye-styrene ibisebenza ngaphansi kwesilinganiso seminyaka eyi-10.Kusukela ngoMeyi, liye lehla kakhulu esilinganisweni seminyaka eyi-10.Isizathu esikhulu ukuthi ingcindezi ye-benzene emsulwa kusukela ekunikezeni amandla okukhulisa izindleko kuye ekwandiseni uhlangothi lwezindleko yenze buthaka intengo ye-styrene.Sekukonke, intengo ye-styrene ingase iqhubeke ithembele ekuqondisweni kwezindleko, futhi ukuvinjelwa kokunikezwa kanye nesidingo ekudlulisweni kwezindleko kungase kube nzima ukuthuthukisa.
Kusukela ngo-2023, izintengo ze-styrene bezilokhu zisebenza ngaphansi kwesilinganiso esinyakazayo seminyaka eyi-10.Ngakolunye uhlangothi, ukukhishwa okusheshisiwe kokukhiqizwa kwe-styrene entsha kuholele ekwehleni okuqhubekayo kobudlelwane bawo bokuhlinzeka nokufunwa;Ngakolunye uhlangothi, kusukela i-Zhongyuan Oil yangena esiteshini esibheke phansi ngo-2022, izinzile futhi yashintshashintsha, akukho mkhuba okhuphukayo.Ngalesi sikhathi, i-benzene ehlanzekile ekhuphuka nomfula ithembele ebudlelwaneni bokunikezwayo obuhle kanye nesidingo ukuze kusekelwe intengo ye-styrene.Kodwa-ke, ngoMeyi, njengoba ubudlelwano bokunikezwa nokufunwa kwe-benzene ehlanzekile buba buthaka kancane kancane, amanani e-styrene

futhi wabhekana nengcindezi ephansi.
 
Izindleko: Kunzima ukuthi uwoyela ongahluziwe ubonise ukuthambekela okuhlangene, kodwa ukunikezwa nokufunwa kwe-benzene emsulwa kungase kube buthakathaka noma kuqhubeke nokuba nengcindezi.
Njengomkhiqizo wamandla, uwoyela ongahluziwe uzoqhubeka nokuguquguquka emakethe ezinyangeni ezintathu ezizayo ngenxa yokwenyuka kwezinga lenzalo enkulu kanye nokuncishiswa kokukhiqizwa.Ngeke kube khona ukungqubuzana okujwayelekile, futhi intengo kawoyela izoqhubeka nokuguquguquka phakathi kwebanga.Uwoyela ongahluziwe wase-US ugxile ku-$65- $85 emgqonyeni ngamunye.Njengamanje, kunezimo ezintathu eziyinhloko ezilawula ukuthambekela kwamanani kawoyela, okuwukuthi ukuqiniswa kwezimali kweFederal Reserve, ukulungiswa kokukhiqizwa kwe-OPEC+, kanye nezinguquko eziseceleni emnothweni omkhulu womhlaba wonke nowaseShayina.Kudingeka ukunaka umthelela wezinguquko ezingalindelekile kumanani kawoyela kulezi zimo ezintathu ezinkulu.
Kusukela ngoMashi walo nyaka, i-benzene emsulwa ithembele kakhulu ekuhlinzekweni nasekufuneni (nesidingo esihle sokuxutshwa kukawoyela e-Europe naseMelika, kanye nemishini yokulungisa eyengeziwe e-Asia, okukhuphula inani le-benzene emakethe yangaphandle; ukunikezwa kwasekhaya kuyefana izinzile, kodwa ngokukhishwa okusheshisiwe kokukhiqizwa okusha komfula, isidingo sinyukile).Ngesikhathi senqubo yokwenyuka kwentengo kawoyela kanye nokwehliswa kwentengo kawoyela, kwaba khona ukukhuphuka okuqinile kwe-styrene, kuyilapho phakathi nenqubo yokwehla kwentengo kawoyela kanye nokwehliswa kokudluliselwa, kube nokusekela okucacile kwentengo ye-styrene.Kusukela emehlukweni wentengo phakathi kwe-benzene emsulwa ne-styrene kuMfanekiso 3, kuyabonakala ukuthi kusukela maphakathi no-March kuze kube sekupheleni kuka-April, i-benzene ehlanzekile incike kakhulu ekuhlinzekweni nasekufuneni, futhi umehluko wentengo nge-styrene uqhubeke uncipha, wehla wafinyelela phakathi kuka-1080. yuan/ton ekupheleni kuka-Ephreli.
Kodwa-ke, ngoMeyi, umthelela we-benzene ehlanzekile ku-styrene waba ntekenteke kakhulu, ikakhulukazi ngenxa yokwanda kancane kancane kwenani lamayunithi okulungisa i-benzene ahlanzekile, ubuningi bezinkontileka zempahla eluhlaza, kanye nokwengezwa kohwebo lwasekhaya ethangini lase-East China. ipulazi, okulindeleke ukuthi linyuse i-inventory.Khonamanjalo, isidingo sokuxutshwa kukawoyela e-Europe naseMelika asizange sikhule, okuhambisana nokukhululwa kwawo.Kodwa-ke, ngokubuya kokulungiswa okukhulu ezitshalweni ze-benzene ezihlanzekile zase-Asia, ukunikezwa kuye kwanda ngokulandelana, futhi amanani angaphandle angaphansi kwengcindezi ethile.
Ubudlelwano bokuhlinzeka nokufunwa: Ubunzima bokudluliselwa kwezindleko kanye namandla okuvimbela
Nakuba kukhona okuguquguqukayo ohlangothini lokuhlinzeka nesidingo, umthelela wezindleko ezintengweni ze-styrene usushintshile ukusuka ekukhuphuleni ukuya ekufakeni ingcindezi, kodwa ubudlelwano bokunikezela nesidingo bungase bube nzima ukubushintsha kakhulu.
Okokuqala, mayelana nokuhlinzekwa, kusukela maphakathi no-May, isibalo semishini yokulungisa i-styrene senyukile, kanti izinkampani eziyi-8 seziqala ukulungisa cishe amathani ayizigidi ezi-3.2 amandla okukhiqiza imishini.NgoJuni, ukukhiqizwa kwe-styrene kulindeleke ukuthi kwehle ngamathani angu-110000 kuya kumathani ayizigidi ezingu-1.24 uma kuqhathaniswa noMeyi, ukwehla ngo-8.15% uma kuqhathaniswa nenyanga edlule.

Okwesibili, ngokwesidingo, ukukhiqizwa kwe-styrene okuningi okuzansi komfula ngo-June kusenkathini engekho yesizini, futhi isidingo se-styrene singase sehle.Ngokusho kwedatha kusuka ku-2021 kuya ku-2022, isidingo se-styrene ezindaweni eziyisikhombisa ezansi nomfula we-styrene sehlile, ngokuncipha okungaphezu kuka-11% ngo-2022. Kodwa-ke, kuseduze noshintsho ekukhiqizeni ngo-2022, futhi kunokuvumelana nezimo phakathi izinhlangothi zokuhlinzeka kanye nesidingo.

Sekukonke, ukuhlinzekwa kanye nesidingo se-styrene kwehle ngo-June, kodwa ngokulungiswa okuguquguqukayo kohlangothi lokuhlinzeka kanye nesidingo, kungase kube nzima ukuthi ubudlelwano bokuhlinzeka nokufunwa kwe-styrene bushintshe kakhulu, okwenza kube nzima ukushayela intengo ye-styrene unilaterally. .Intengo ye-styrene ingase iqhubeke nokuncika kuzinkombandlela zokushintsha zohlangothi lwezindleko.
