Amanani entengo e-Styrene ayevukile abese elungiswa emuva emcabangweni we-oscillating. Ngesonto eledlule, isivumelwano esiphakeme kakhulu eJiangsu ngo-10,150 yuan / ithoni, isivumelwano esiphansi se-9,750 yuan / ithoni, ukuphela okuphezulu nokuphansi kokusakazwa ngo-400 yuan / toni. Amanani entengo kawoyela we-crude abusa i-styrene, futhi i-benzene emsulwa ihlala iqinile, ku-streneback yentengo kawoyela, futhi icindezele inzuzo ye-styrene, icala lezindleko liyaqhubeka nokusekela, futhi ekugcineni kwezindleko uwoyela uwoyela ngenkathi elandela ukukhuphuka. Isidingo esiphansi, izisekelo ziyaqhubeka, izixhasi kanye nenzuzo yokukhiqiza kanye nenzuzo yokukhiqiza ngaphansi kwethonya lesitshalo se-Domed TownTream iqala ukulimala, ukulethwa kanye nesidingo uhlangothi kunzima ukukhuphula i-styrene.

Uhlangothi lokuhlinzekwa
Njengamanje, isitshalo sasekhaya sasekhaya siqala ezingeni eliphansi, ngaphansi kwethonya lenzuzo yokukhiqiza, izitshalo eziningi ezihlanganiswe zikupaka ukunciphisa okungekuhle, okuyingxenye yedivayisi ehlanganisiwe noma ukulungiswa, noma ukwehliswa komthwalo, kuphela ukwenza umkhiqizo ungakhuphuki. Ngakho-ke, ukukhiqizwa kwasekhaya kweStyrene kunzima ukucindezela amanani entengo, futhi okwenza ukuthi ukukhiqizwa kwaleli sonto kungabonakali, kuyilapho ukwehliswa kwakamuva kwe-lihua yi e-stysene kuncishiswe kancane. Ukukhiqizwa kwe-Styrene ephelele kuzokwanda esikhathini esizayo njengoba umphumela wamayunithi athile aqala kabusha.
Isidingo Side
Isidingo esiphansi se-Downstream asikashintshi okuningi esikhathini esizayo esiseduze, ngenxa yokuncishiswa okungalungile kwakamuva kwabakhiqizi, ukufunwa kwe-Styrene kuncishiswe ukuncishiswa kwesicelo esiseduze, futhi kunegumbi elithile lokuthuthukisa ukufunwa kwesikhathi. Ubhubhane lwamanje kuphela e-East China lunomthelela omkhulu ekufunweni kwe-styrene noma ngezinga elithile lokucindezela.
Njengamanje, amanani entengo kawoyela akhunjulwa ezingeni eliphakeme, ekhuphuka futhi lilinganiselwe; Amanani ama-Benzene ahlanzekile ayaqhubeka nokuqina, kepha imakethe efushane ephoqelekile ingahlala isikhathi eside ukukhathazeka kakhulu, ikakhulukazi uma intengo kawoyela ibuyela emuva, i-benzene emsulwa noma ngokuwohloka; Ngakho-ke, yize kukhona ukwesekwa kohlangothi lwezindleko, kepha izindleko zokuthi kungenzeka kube yinto yokudonsa, ukusekelwa kwezindleko nakho ngokuncipha. Ukuhlinzekwa kanye nokufunwa ohlangothini ukuze kugcinwe, uhlangothi oluhlinzekwayo, ukuphuma kwefekthri ye-Styrene kuzinzile, kanye nokwanda okuncane kwedolobha; Ngenkathi uhlangothi olufunwayo, ubhubhane lwendawo yeJiangsu luyaqhubeka, izitshalo ze-eps ngazinye ezithintwe ukupaka, i-PS kungenxa yezinkinga zenzuzo Ezinye izitshalo ezinenhloso yokupaka umthwalo. Ngakho-ke, kuleli sonto, amanani entengo ezifuywayo alinganiselwe, futhi kungahle kube nokwehla, intengo yamabala eMakethe yeJiangsu kulindeleke ukuthi ibe phakathi kuka-9700-10000 yuan / Ton.
