Izintengo zasekhaya ze-styrene zenyuka zase zilungiswa zibuyela kumkhuba oscillating.Ngesonto eledlule, idili lendawo eliphezulu e-Jiangsu ngama-yuan angu-10,150 / ton, isivumelwano esisezingeni eliphansi esingu-9,750 yuan / ton, isiphetho esiphezulu nesiphansi sokusabalala ku-400 yuan / ton.Amanani kawoyela ongahluziwe abusa i-styrene, futhi i-benzene ehlanzekile ihlala iqinile, entengo kawoyela idonsela emuva, futhi inzuzo ecindezelwe ye-styrene, uhlangothi lwezindleko luyaqhubeka nokusekela, futhi ekupheleni kwesonto uwoyela ongahluziwe uyaphindeka ngenkathi kulandela ukukhuphuka.Isidingo esingaphansi komfula sijwayelekile, okuyisisekelo kuyaqhubeka, ubhubhane kanye nenzuzo yokukhiqiza ngaphansi kwethonya lesitshalo sasekhaya esiwela phansi iqala impofu, uhlangothi lokuhlinzeka kanye nesidingo kunzima ukukhulisa i-styrene.

Uhlangothi lokunikezela
Njengamanje, isitshalo se-styrene sasekhaya siqala ezingeni eliphansi, ngaphansi kwethonya lenzuzo yokukhiqiza, izitshalo eziningi ezingahlanganisiwe zisendaweni yokupaka ukunciphisa okungalungile, ingxenye yedivayisi edidiyelwe noma ukulungiswa, noma ukuwohloka kokupaka nokunciphisa umthwalo, kuphela. ukwenza ukukhiqizwa akuzange kwenyuke.Ngakho-ke, ukukhiqizwa kwasekhaya kwe-styrene kunzima ukucindezela amanani, okwenza futhi ukuguquguquka kokukhiqizwa kwaleli sonto kungabonakali, kuyilapho ukuncishiswa kwakamuva kwe-negative Lihua Yi kwenza ukukhiqizwa kwamasonto onke kwe-styrene kuncishiswe kancane.Ukukhiqizwa kwe-styrene yasekhaya sekukonke kuzokhuphuka esikhathini esizayo njengoba ukukhishwa kwamanye amayunithi kuqhubeka futhi.
Uhlangothi lwesidingo
Isidingo se-downstream asishintshile kakhulu esikhathini esizayo esiseduze, i-EPS ngenxa yokwehliswa okungalungile kwakamuva kwabakhiqizi abathile, isidingo se-styrene sehlile, kodwa isidingo sesitshalo se-PS kanye ne-ABS sanda, ngakho-ke, jikelele, ukuncishiswa kwesidingo esikhulu se-downstream kulinganiselwe kakhulu esikhathini esizayo esiseduze. , futhi kukhona indawo yokuthuthukisa ukufunwa ngasekupheleni kwesikhathi.Kuphela ubhubhane olukhona manje e-East China olunomthelela omkhulu ekufuneni kwe-styrene noma izinga elithile lokucindezelwa.
Njengamanje, amanani kawoyela akhuphukele phezulu, akhuphuka futhi anomkhawulo;izintengo ze-benzene ezihlanzekile ziyaqhubeka nokuqina, kodwa imakethe emfushane ephoqelelwe ingahlala isikhathi eside iyakhathaza kakhulu, ikakhulukazi uma intengo kawoyela idonsela emuva, i-benzene emsulwa noma ngokwehla;ngakho-ke, nakuba kukhona ukusekelwa kohlangothi lwezindleko, kodwa izindleko zokuthi kungenzeka ukudonsa emuva, ukusekelwa kwezindleko nakho nokwehla.Uhlangothi lokunikezela kanye nesidingo lokunakekela, uhlangothi lokunikezela, okukhiphayo kwefekthri ye-styrene kuzinzile, kanye nokwenyuka okuncane kwedolobha;kuyilapho uhlangothi lwesidingo, ubhubhane lwendawo ye-Jiangsu luqhubeka, izitshalo ze-EPS ezithintekayo zokupaka, i-PS ibangelwa izinkinga zenzuzo ezinye izitshalo zinenhloso yokupaka ukuze zinciphise umthwalo.Ngakho-ke, kuleli sonto, izintengo ze-styrene zasekhaya zilinganiselwe, futhi kungase kube nokwehla, intengo yendawo emakethe ye-Jiangsu kulindeleke ukuthi ibe phakathi kuka-9700-10000 yuan / ton.
