Kwikota yesithathu, unikezelo kunye nemfuno yemarike ye-acrylonitrile yayibuthathaka, uxinzelelo lweendleko zefektri lwalucacile, kwaye ixabiso lemarike libuyele emva kokuwa. Kulindeleke ukuba imfuno esezantsi ye-acrylonitrile inyuke kwikota yesine, kodwa amandla ayo aya kuqhubeka esanda, kwayeixabiso Acrylonitrileinokuhlala iphantsi.
Amaxabiso e-Acrylonitrile abuyele emva kokuwa kwikota yesithathu
Ikota yesithathu ye-2022 yenyuka emva kokuhla kwekota yesithathu ye-022. Kwikota yesithathu, ukubonelela kunye nemfuno ye-acrylonitrile yehla ngokuthe ngcembe, kodwa uxinzelelo lweendleko zefektri lwalubonakala. Emva kokuba ukugcinwa komenzi kunye nemisebenzi yokunciphisa umthwalo inyukile, isimo sengqondo sexabiso saphuculwa kakhulu. Emva kokwandiswa kweetoni ze-390000 ze-acrylonitrile kwisiqingatha sokuqala salo nyaka, i-downstream yandisa kuphela i-750000 yeetoni zamandla e-ABS, kwaye ukusetyenziswa kwe-acrylonitrile kwanda ngeetoni ezingaphantsi kwe-200000. Kumxholo wokubonelela ngokukhululekileyo kwishishini le-acrylonitrile, ugxininiso lwentengiselwano yemarike yehle kancinci xa kuthelekiswa nekota yesibini. Ukususela ngoSeptemba 26, ixabiso eliqhelekileyo lemarike ye-Shandong acrylonitrile kwikota yesithathu yayiyi-9443 yuan / ton, phantsi kwe-16.5% ngenyanga ngenyanga.

Icala lokubonelela: Kwisiqingatha sokuqala salo nyaka, uLihua Yijin usulunge iitoni ze-oyile ezingama-260000, kwaye umthamo omtsha kaTianchen Qixiang wawuziitoni eziyi-130000. Ukukhula kwemfuno esezantsi bekusezantsi kunokubonelela. Ukususela ngoFebruwari walo nyaka, izityalo ze-acrylonitrile ziye zaqhubeka zilahlekelwa yimali, kwaye intshiseko yabanye abavelisi iyancipha. Kwikota yesithathu, iiseti ezininzi zeeyunithi ze-acrylonitrile zalungiswa e-Jiangsu Silbang, e-Shandong Kruer, e-Jilin Petrochemical, nase-Tianchen Qixiang, kwaye imveliso yoshishino yawa ngokukhawuleza ngenyanga ngenyanga.
Icala lemfuno: Inzuzo ye-ABS iye yaba buthathaka kakhulu, yade yalahlekelwa yimali ngoJulayi, kwaye umdla wabavelisi ukuqalisa ukwakha wehlile kakhulu; Ngo-Agasti, kwakukho imozulu eninzi eshushu ehlotyeni, kwaye umthwalo wokuqala wesityalo se-acrylamide wehla kancinci; NgoSeptemba, i-Northeast Acrylic Fiber Factory yahlaziywa, kwaye ishishini laqala ukusebenza ngaphantsi kwe-30%.
Iindleko: ixabiso eliqhelekileyo lepropylene njengeyona nto ingundoqo kunye ne-synthetic ammonia yehle nge-11.8% kunye ne-25.1% ngokulandelanayo.
Amaxabiso e-Acrylonitrile anokuhlala ephantsi kwikota yesine
Icala lokubonelela: Kwikota yesine, iiseti ezininzi zeeyunithi ze-acrylonitrile zilindeleke ukuba zigcinwe kwaye zifakwe kwimveliso, kubandakanywa neetoni ze-260000 ze-Liaoning Jinfa, iitoni ze-130000 ze-Jihua (Jieyang) kunye ne-200000 yeetoni ze-CNOOC Dongfang Petrochemical. Okwangoku, izinga lomthwalo wokusebenza kwishishini le-acrylonitrile liye lahla kwinqanaba eliphantsi, kwaye kunzima ukunciphisa kakhulu umthwalo wokusebenza kwikota yesine. Ukunikezelwa kwe-Acrylonitrile kulindeleke ukuba kwandiswe.
Icala lemfuno: Umthamo we-ABS kumsinga osezantsi uyanda kakhulu, kunye nomthamo omtsha oqikelelwayo we-2.6 yezigidi zeetoni; Ukongezelela, umthamo omtsha weetoni ze-200000 ze-butadiene acrylonitrile latex kulindeleke ukuba zifakwe kwimveliso, kwaye imfuno ye-acrylonitrile kulindeleke ukuba inyuke, kodwa ukunyuka kweemfuno kungaphantsi kokunyuka kokunikezelwa, kunye nenkxaso esisiseko ilinganiselwe.
Kwicala leendleko: amaxabiso epropylene kunye ne-synthetic ammonia, izinto eziphambili zezinto ezibonakalayo, kulindeleke ukuba ziwe emva kokunyuka, kwaye amaxabiso aphakathi kwikota yesithathu ayinakuhluka kakhulu. Ifektri ye-acrylonitrile yaqhubeka ilahlekelwa yimali, kwaye iindleko zisaxhasa ixabiso le-acrylonitrile.
Okwangoku, imarike ye-acrylonitrile ijongene nengxaki yokugqithiswa kwamandla. Ngaphandle kokukhula kabini kokubonelela kunye nemfuno kwikota yesine, ukukhula kwemfuno kulindeleke ukuba kube ngaphantsi kunokubonelela. Imeko yokunikezelwa okuxekethileyo kwishishini le-acrylonitrile liyaqhubeka, kwaye uxinzelelo lweendleko lusekho. Imarike ye-acrylonitrile kwikota yesine ayiyi kuba nokulindela okucacileyo okuqinisekileyo, kwaye ixabiso linokuhlala liphantsi.
