Kwikota yesithathu, iningi lemikhiqizo eChina e-Acetone embonini yaseChina ikhombisa ukuthambekela okuqhubekayo okuqhubekayo. Amandla amakhulu okushayela alo mkhuba ukusebenza okuqinile kwemakethe yamafutha aphesheya engaphandle, okuye kwaqhubekela phambili okuqinile kwemakethe yezinto ezibonakalayo ezikhuphukayo, ikakhulukazi ukwanda okuphambili okuqhubekayo emakethe ye-benzene emsulwa. Kulesi simo, uhlangothi lwezindleko ze-Acetone Ikati luphawula ukwenyuka kwamanani, ngenkathi imithombo yokungenisa e-Acetone isasenqabile, imboni ye-Phenol Ketone inezilinganiso eziphansi zokusebenza, futhi ukulethwa kwendawo kuqinile. Lezi zinto ndawonye zisekela ukusebenza okuqinile kwemakethe. Ngalesi sikhathi ngalelikota, intengo ephezulu ye-Acetone eMakethe yase-East China yayicishe ibe ngu-7600 yuan ngethani eliphansi, ngenkathi umehluko wentengo ngethani elingu-2350 phakathi kokuphela okuphezulu nokuphansi.

Ake sibukeze izizathu zokuthi kungani imakethe ye-acetone yasekhaya iqhubeka ikhuphuka kwikota yesithathu. Ekuqaleni kukaJulayi, inqubomgomo yokukhokhisa intela yokusebenzisa kwezinto ezithile zophethiloli igcizelele izintengo zezinto ezisetshenziswayo eziqinile, futhi ukusebenza kwe-benzene emsulwa kanye ne-propylene nakho bekuqinile kakhulu. Izimakethe ezaphansi ze-bisphenol a ne-isopropanol nazo zithole amazinga ahlukahlukene okukhuphuka. Ngaphansi kwendawo efudumele efudumele, imakethe yamakhemikhali yasekhaya ngokuvamile ibone ukwanda. Ngenxa yomthwalo ophansi wesitshalo sethani le-650000 Phenol Ketone eJiangsu Ruiheng kanye nokuhlinzekwa nge-acetone, abahlinzeki babambe izimpahla bakhuphuke kakhulu amanani abo. Lezi zinto ziye zaqhutshwa ngokuhlangene ukukhuphuka okuqinile kwemakethe. Kodwa-ke, kusukela ngo-Agasti, ukufunwa phansi kwehla kwenyuka buthaka, futhi amabhizinisi akhombise izimpawu zobuthakathaka ekuqhubeni amanani entengo, futhi kube nomkhuba wokuyeka inzuzo. Noma kunjalo, ngenxa yemakethe eqinile ye-Benzezene emsulwa, i-Ningbo Taihua, Huizhou Zhongxin, kanye ne-Bluestar Harbin Phenol Ketone izitshalo zigcinwa. I-Jiangsu Ruiheng ka-650000 Ton Penol Ketone isitsha ngokungazelelwe ngomhlaka 18, okuye kwaba nomthelela omuhle ezimweni zemakethe kanye nokuzimisela kwamabhizinisi 'ukuyeka inzuzo akunamandla. Ngaphansi kokuhlangana kwezinto ezahlukahlukene, imakethe ibonakala ikakhulukazi ngokushintshashintsha kwesikhashana.

Ngemuva kokungena ngoSepthemba, imakethe yaqhubeka nokunamandla. Ukukhuphuka okuqhubekayo kwemakethe yamafutha e-International Crude, umkhuba onamandla wemvelo ephelele, futhi ukukhula kwezinto ezibonakalayo ezihlaselayo ze-benzene ezihlanzekile ziholele ekunyuseni okujwayelekile kwemikhiqizo ye-phenolic yetone imboni embonini. Amandla aqhubekayo we-BISTSTream Bisphenol imakethe ehoxile isidingo esihle se-acetone, futhi abahlinzeki baphethe izimpahla zokwandisa amanani futhi baqhubekele phambili emakethe. Ngaphezu kwalokho, ukusungulwa kwechweba akulona ophakeme, futhi izitshalo zamakhemikhali ze-wanhua kanye ne-bluestar phenol ketone zigcinwa. Ukuhlinzekwa kwe-Spot kuyaqhubeka ukuqina, nge-Downstream ikakhulukazi kulandela ukufunwa. Lezi zinto ziqhutshwe ngokuhlangene ukuqhubeka kwaqhubeka ngamanani emakethe. Ngokusekupheleni kwekota yesithathu, inani lokuvala le-East China Acetone Market lalingama-7500 yuan ngethani ngalinye, ukukhuphuka kwama-2275 yuan noma ama-43.54% kuqhathaniswa nokuphela kwekota edlule.

Kodwa-ke, kulindeleke ukuthi futhi ukuzuza emakethe ye-acetone e-East China kungaphazanyiswa kwikota yesine. Njengamanje, uhlu lwamachweba we-acetone luphansi, futhi ukunikezwa okuphelele kuqinile kancane, ngamanani angenamkhawulo. Kodwa-ke, kungaba nzima ngakolunye uhlangothi lwezindleko ukuze ube ne-push eqinile futhi. Ikakhulu ngemuva kokufaka ikota yesine, ukukhiqizwa kwamayunithi amasha we-phenolic katone kuzogxila, futhi ukuhlinzekwa kuzokhuphuka kakhulu. Yize uMbuso Wenzuzo wama-Phenolic Ketones ulungile, ngaphandle kwamabhizinisi abhekene nokunakekelwa okujwayelekile, amanye amabhizinisi azogcina ukukhiqizwa kwemithwalo ephezulu. Kodwa-ke, amayunithi amaningi amasha we-phenolic yetone afakwe i-bisstream bisphenol amayunithi, ngakho-ke ukuthengiswa kwangaphandle kwe-acetone ngamabhizinisi aphansi asetshenziswa kuncane. Sekukonke, kulindeleke ukuthi ekuqaleni kwekota yesine, imakethe yasekhaya yasekhaya ingahle iguquke futhi ihlanganise; Kepha njengoba ukulethwa kukhuphuka, imakethe ingaphenduka ibuthakathaka ngezigaba zakamuva.
