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 yechweba 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.
