Ngekota yesithathu, imikhiqizo eminingi embonini ye-acetone yaseShayina ikhombise ukuguquguquka okunyukayo.Okuhamba phambili kulo mkhuba ukusebenza okuqinile kwemakethe kawoyela ongahluziwe yamazwe ngamazwe, okuphinde kwaqhuba inkambiso eqinile yemakethe yempahla eluhlaza, ikakhulukazi ukukhula okuqhubekayo kwemakethe ye-benzene ehlanzekile.Kulesi simo, uhlangothi lwezindleko lochungechunge lwemboni ye-acetone lulawula ukukhuphuka kwentengo, kuyilapho imithombo yokungenisa i-acetone isantuleka, imboni ye-phenol ketone inamazinga aphansi okusebenza, futhi ukutholakala kwamabala kuqinile.Lezi zinto zihlangene zisekela ukusebenza okuqinile kwemakethe.Phakathi nale kota, intengo ephezulu ye-acetone emakethe ye-East China yayicishe ibe ngama-yuan angama-7600 ngethani, kanti intengo ephansi yayingamayuan angama-5250 ngethani, nomehluko wentengo wamayuan angama-2350 phakathi kwesiphetho esiphezulu nesiphansi.

Ake sibuyekeze izizathu zokuthi kungani imakethe ye-acetone yasekhaya iqhubeka nokukhuphuka ngekota yesithathu.Ekuqaleni kukaJulayi, inqubomgomo yokukhokhisa intela yokusetshenziswa kwezinye izinto zokusetshenziswa kukaphethiloli yagcina amanani ezinto ezingavuthiwe eqinile, nokusebenza kwe-benzene emsulwa nepropylene nakho kwakunamandla kakhulu.Izimakethe ezansi nomfula ze-bisphenol A ne-isopropanol nazo zihlangabezane namazinga ahlukahlukene okukhuphuka.Ngaphansi kwemvelo efudumele, imakethe yamakhemikhali yasekhaya ngokuvamile ibone ukwanda.Ngenxa yomthwalo ophansi we-650000 ton phenol ketone plant e-Jiangsu Ruiheng kanye nokutholakala okuqinile kwe-acetone, abahlinzeki abaphethe izimpahla banyuse kakhulu amanani abo.Lezi zici ziqhube ngokuhlanganyela ukukhuphuka okuqinile kwemakethe.Kodwa-ke, kusukela ngo-Agasti, isidingo esingaphansi komfula sesiqalile ukuba buthaka, futhi amabhizinisi abonise izimpawu zobuthakathaka ekukhuphuleni amanani, futhi sekunomkhuba wokuyeka inzuzo.Noma kunjalo, ngenxa yemakethe eqinile ye-benzene emsulwa, izitshalo ze-Ningbo Taihua, i-Huizhou Zhongxin, kanye ne-Bluestar Harbin phenol ketone ziyalungiswa.Isitshalo sika-Jiangsu Ruiheng sika-650000 se-phenol ketone plant sama kungazelelwe ngomhlaka-18, esibe nomthelela omuhle emuzweni wemakethe kanye nokuzimisela kwamabhizinisi ukuyeka inzuzo akunamandla.Ngaphansi kwe-interweaving yezinto ezahlukahlukene, imakethe ibonakala kakhulu ngokuguquguquka kwezikhawu.

Ngemva kokungena ngoSepthemba, imakethe yaqhubeka nokuba namandla.Ukukhuphuka okuqhubekayo kwemakethe kawoyela ongahluziwe yamazwe ngamazwe, ukuthambekela okuqinile kwendawo yonke, kanye nokukhula kwemakethe ye-benzene ehlanzekile kuholele ekwenyukeni okujwayelekile kwemikhiqizo yochungechunge lwezimboni ze-phenolic ketone.Amandla aqhubekayo emakethe ye-bisphenol A ezansi nomfula aqhubekisele phambili isidingo esihle se-acetone, futhi abahlinzeki abaphethe izimpahla bathathe leli thuba ukukhulisa amanani futhi baqhubekisela phambili ukukhula kwemakethe.Ngaphezu kwalokho, i-inventory ye-port ayiphezulu, futhi izitshalo ze-Wanhua Chemical kanye ne-Bluestar Phenol Ketone ziyalungiswa.Ukunikezwa kwezindawo kuyaqhubeka nokuqina, ngomfula ongezansi ikakhulukazi ukulandela kancane kwesidingo.Lezi zici ziqhube ngokuhlanganyela ukunyuka kwamanani emakethe.Kusukela ekupheleni kwekota yesithathu, intengo yokuvala yemakethe ye-acetone yase-East China ibingama-yuan angama-7500 ngethani, okuwukunyuka kwama-yuan angama-2275 noma ngo-43.54% uma kuqhathaniswa nokuphela kwekota edlule.

Kodwa-ke, kulindeleke ukuthi okunye ukuzuza emakethe ye-acetone eMpumalanga China kungase kuvinjwe ikota yesine.Njengamanje, inani lamachweba e-acetone liphansi, futhi ukuhlinzekwa okuphelele kuqinile kancane, namanani aqinile.Nokho, kungase kube nzima ukuthi uhlangothi lwezindleko lube nokuphusha okuqinile futhi.Ikakhulukazi ngemva kokungena engxenyeni yesine, ukukhiqizwa kwamayunithi amasha e-phenolic ketone kuzogxila, futhi ukunikezwa kuzokwanda kakhulu.Nakuba umkhawulo wenzuzo wama-phenolic ketones umuhle, ngaphandle kwamabhizinisi abhekana nokulungiswa okujwayelekile, amanye amabhizinisi azogcina ukukhiqizwa kwemithwalo ephezulu.Kodwa-ke, amayunithi amaningi amasha e-phenolic ketone afakwe amayunithi e-bisphenol A angezansi, ngakho ukuthengiswa kwangaphandle kwe-acetone ngamabhizinisi angaphansi komfula ayisebenzisayo kuncane kakhulu.Sekukonke, kulindeleke ukuthi ekuqaleni kwekota yesine, imakethe ye-acetone yasekhaya ingase iguquguquke futhi ihlanganise;Kodwa njengoba ukunikezwa kwanda, imakethe ingase ibe buthakathaka ezigabeni zakamuva.
