Engxenyeni yokuqala yonyaka, imakethe ye-acetone yasekhaya yaphakama kuqala bese yehla. Ngekota yokuqala, ukungeniswa kwe-acetone kwamanye amazwe bekuyindlala, ukugcinwa kwemishini kugxilile, futhi amanani emakethe ayeqinile. Kodwa kusukela ngoMeyi, izinto ezithengiswayo ngokuvamile zehlile, futhi izimakethe ezingezansi nezisekupheleni bezibuthakathaka. Kusukela ngomhla zingama-27 kuJuni, imakethe ye-acetone yaseMpumalanga ye-China ivalwe ngo-5150 yuan/ton, ukwehla okungu-250 yuan/ton noma u-4.63% uma kuqhathaniswa nokuphela konyaka odlule.
Kusukela ekuqaleni kukaJanuwari kuze kube sekupheleni kuka-April: Kube nokwehla okukhulu kwezimpahla ezingeniswa kwamanye amazwe, okuholele emananini aqinile ezimakethe ezimpahleni.
Ekuqaleni kukaJanuwari, i-inventory yechweba yanda, isidingo esingaphansi komfula sasivilapha, nomfutho wemakethe wehla. Kodwa lapho imakethe yaseMpumalanga China yehlela ku-4550 yuan/ton, inzuzo yaqina ngenxa yokulahlekelwa okukhulu kwabanikazi. Ngaphezu kwalokho, i-Mitsui Phenol Ketone Plant yehlile, futhi umuzwa wemakethe uye waphindeka omunye ngemva komunye. Ngesikhathi seholide loMkhosi waseNtwasahlobo, imakethe yangaphandle yayiqinile, futhi izinto ezingavuthiwe ezimbili zenza isiqalo esihle emakethe. Imakethe ye-acetone iyakhula ngokukhuphuka kweketango lezimboni. Ngokushoda kwempahla engenisiwe ukuze kugcinwe i-Saudi phenolic ketone plant, isitshalo esisha se-phenolic ketone se-Shenghong Refining and Chemical sisesesigabeni sokulungisa iphutha. Izintengo zekusasa ziqinile, futhi imakethe iyaqhubeka nokuwohloka. Ngaphezu kwalokho, kukhona ukushoda kwezimpahla ezitholakala emakethe yaseNyakatho neChina, futhi uLihuayi ukhuphule kakhulu intengo yefekthri ukuze aqhubekisele phambili imakethe yase-East China.
Ekuqaleni kukaMashi, inani le-acetone eJiangyin lehla laya ezingeni lamathani ayi-18000. Kodwa-ke, ngesikhathi sokunakekelwa kwemboni ka-Ruiheng's 650000 ton phenol ketone plant, ukunikezwa kwendawo emakethe kwahlala kuqinile, futhi abanikazi bempahla babenezinhloso zamanani aphezulu, okuphoqe izinkampani ezansi nomfula ukuthi zilandele kancane. Ekuqaleni kukaMashi, uwoyela ongahluziwe wamazwe ngamazwe waqhubeka ukwehla, ukwesekwa kwezindleko kwehla, futhi isimo somnotho sezimboni saba buthaka. Ngaphezu kwalokho, imboni yasekhaya ye-phenolic ketone isiqalile ukukhuphuka, okuholela ekwandeni kokuhlinzekwa kwasekhaya. Kodwa-ke, izimboni eziningi ezansi nomfula ziye zalahlekelwa ukukhiqizwa, okuye kwanciphisa umdlandla wokuthengwa kwezinto ezingavuthiwe, kwakhinyabeza ukuthunyelwa kwabathengisi, futhi kwaholela emuzweni wokunikeza inzuzo, okubangele ukwehla kancane kwezimakethe.
Kodwa-ke, kusukela ngo-Ephreli, imakethe iphinde yaqina. Ukuvalwa nokunakekelwa kwe-Huizhou Zhongxin Phenol Ketone Plant kanye nokugcinwa kwesethi ye-Phenol Ketones e-Shandong kuqinise ukuzethemba kwabaphethe futhi kwathola imibiko ephakeme yokuhlola. Ngemva koSuku Lokushanela Amathuna, babuya. Ngenxa yokudonsa kanzima eNyakatho ye-China, abanye abathengisi bathenge izimpahla ezivela e-East China, okuphinde kwavusa isasasa kubathengisi.
Kusukela ekupheleni kuka-April kuya ekupheleni kukaJuni: Isidingo sokuqala esiphansi sicindezela ukwehla okuqhubekayo kwezimakethe ezingezansi
Kusukela ngoMeyi, nakuba amayunithi amaningi e-phenol ketone asalungiswa futhi ingcindezi yokuhlinzeka ayiphezulu, nesidingo esiphansi somfula siba nzima ukulandela, ukufunwa kuye kwaba buthaka kakhulu. Amabhizinisi e-isopropanol ase-acetone aseqale ukusebenza ephansi kakhulu, futhi imakethe ye-MMA ibe buthakathaka kusukela ekuqineni kuye ebuthakathakeni. Imakethe ye-bisphenol A engezansi nayo ayiphezulu, futhi isidingo se-acetone siphansi. Ngaphansi kwezingqinamba zesidingo esibuthakathaka, amabhizinisi kancane kancane asuke enzuzweni yokuqala aya ekuphoqweni ukuthi athumele futhi alinde ezansi nomfula ukuze athenge amanani aphansi. Ngaphezu kwalokho, imakethe yezimpahla ezingavuthiwe ezimbili iyaqhubeka nokwehla, nokwesekwa kwezindleko kuncipha kanye nemakethe iqhubeka nokwehla.
Ngasekupheleni kukaNhlangulana, kube nokugcwaliswa kabusha kwezimpahla ezivela kwamanye amazwe kwakamuva kanye nokwenyuka kwempahla ethekwini; Inzuzo yefekthri ye-phenol ketone iye yaba ngcono, futhi izinga lokusebenza kulindeleke ukuthi lenyuke ngoJulayi; Mayelana nesidingo, ifektri idinga ukulandelela ngokugcwele. Nakuba abadayisi abaphakathi bebambe iqhaza, ukuzimisela kwabo kokusungula akuphezulu, futhi ukugcwalisa kabusha okusebenzayo akuphezulu. Kulindeleke ukuthi imakethe izolungisa kancane ezinsukwini ezimbalwa ezizayo ekupheleni kwenyanga, kodwa ukuguquguquka kwemakethe akubalulekile.
Ukubikezelwa kwemakethe ye-acetone engxenyeni yesibili yonyaka
Engxenyeni yesibili ka-2023, imakethe ye-acetone ingase ibe nokuguquguquka okubuthakathaka kanye nokwehla kokuguquguquka kwesikhungo samanani. Izitshalo eziningi ze-phenolic ketone e-China ngokuyisisekelo zibekwe endaweni eyodwa ukuze zigcinwe engxenyeni yokuqala yonyaka, kuyilapho izinhlelo zokunakekela ziyindlala engxenyeni yesibili, okuholela ekusebenzeni okuzinzile kwezitshalo. Ngaphezu kwalokho, i-Hengli Petrochemical, i-Qingdao Bay, i-Huizhou Zhongxin Phase II, kanye ne-Longjiang Chemical bahlela ukusebenzisa amasethi amaningi amayunithi e-phenolic ketone, futhi ukwanda kokuhlinzeka kuwumkhuba ongenakugwenywa. Nakuba imishini ethile emisha ifakwe i-bisphenol A engezansi, isekhona i-acetone eningi, futhi ingxenye yesithathu ngokuvamile iyisizini ephansi yesidingo setheminali, esithambekele ekwehleni kodwa okunzima ukukhuphuka.
