Imakethe ye-cyclohexanone isanda kubonisa ubuthakathaka obuthile, amanani asebenza emazingeni aphansi kakhulu kanti imboni ibhekene nezingcindezi ezithile zenzuzo.
I. Amanani Emakethe Amanje (Ekuqaleni kukaSepthemba 2025)
Idatha evela kumapulatifomu amaningi olwazi ikhombisa ukuthi amanani akamuva e-cyclohexanone abelokhu eqinile kodwa ebuthakathaka. Kusukela ngomhlaka-29 Agasti 2025, amanani e-East China ehle ngo-26.13% unyaka nonyaka, ahlala ekugcineni okuphansi kobubanzi obubonwe eminyakeni yamuva.
II. Ukuhlaziywa Kwemakethe kanye Nombono Wesikhathi Esizayo
Imakethe ye-cyclohexanone iqhubekile nokubhekana nengcindezi muva nje, ikakhulukazi ngenxa yezizathu ezilandelayo:
1.Ukusekelwa Kwezindleko Okwanele:
Intengo ye-benzene emsulwa, into eluhlaza eyinhloko ye-cyclohexanone, ibilokhu ishintshashintsha kancane kancane.
I-benzene emsulwa ibiza ngaphezu kuka-70% wezindleko zokukhiqiza i-cyclohexanone. Intengo yayo ebuthakathaka yehlisa ngqo izindleko ze-cyclohexanone, okuholela ekuntulekeni kokusekelwa okuqinile ohlangothini lwezindleko.
2.Ukusebenza Okubuthakathaka Kwesidingo:
Isidingo esiphansi se-cyclohexanone (isb. i-caprolactam, izinyibilikisi) siye sathinteka kabi yisimo sezomnotho kanye nokusetshenziswa okubuthakathaka kwe-terminal.
Ama-oda e-fiber yamakhemikhali angaphansi komhlaba abe eqaphile, lapho ukuthengwa kuqhutshwa kakhulu yisidingo esiqinile, futhi ukuthengwa okukhulu okuphakathi akuvamile.
3.Ukulahlekelwa Okwandayo Kwemboni:
Ngenxa yokucindezeleka kwezindleko kanye namanani aphansi omkhiqizo, ukulahlekelwa embonini ye-cyclohexanone kuye kwanda kakhulu. Idatha ikhombisa ukuthi ngo-Agasti 2025, amabhizinisi e-cyclohexanone asebenzisa ubuchwepheshe bokumanzisa athole ukulahlekelwa okungaba yi-RMB 660 ngethani, okumelela ukwanda kwenyanga nenyanga.
4.Ukunikezwa Okuzinzile Ngokulinganiselwe:
Nakuba ezinye izindawo zokukhiqiza ziye zashintsha, ngokuvamile, ukunikezwa kwe-cyclohexanone kusalokhu kuzinzile. Ngaphezu kwalokho, uchungechunge lwemboni ye-cyclohexanone-caprolactam oluhlanganiswe kahle luye lwathonya nomthamo wezimpahla zemakethe.
Sekukonke, kulindeleke ukuthi imakethe ye-cyclohexanone izoqhubeka nokuqina esikhathini esifushane. Ngaphansi kwezingcindezi ezimbili "zokusekelwa kwezindleko okwanele kanye nesidingo esibuthakathaka," imakethe cishe izogcina umkhuba obuthakathaka noguquguqukayo.
III. Izici Okufanele Ziqashwe
Esikhathini esizayo, izici ezilandelayo zingathinta kakhulu imakethe ye-cyclohexanone:
Izitayela zamanani kawoyela ongahluziwe emhlabeni wonke: Njengomthombo we-benzene emsulwa, ukuguquguquka kwentengo kawoyela ongahluziwe kuzodlulela ku-benzene emsulwa kanye ne-cyclohexanone.
Ukubuyiselwa kwesidingo esingezansi: Ikakhulukazi, ukuthi isidingo ezimbonini ezifana ne-caprolactam singathuthuka ngempumelelo kuzoba yisihluthulelo semakethe ye-cyclohexanone ephuma emkhubeni wayo obuthakathaka.
Izinqubomgomo ezinkulu kanye nokuguquguquka kokungenisa/ukuthumela ngaphandle: Izinqubomgomo zentela ezifanele noma izinguquko endaweni yokuhweba nazo zingathinta imizwa yemakethe kanye nesidingo sangempela.
IV. Isifinyezo
Imakethe yamanje ye-cyclohexanone ibonakala ngokulinganisela okubuthakathaka kokuhlinzekwa kwezidingo, ukusekelwa okunganele kwezindleko, kanye nokusebenza okungekuhle kwezidingo, okuholela emananini aphansi kanye nemboni ebhekene nezingcindezi zenzuzo. Kulindeleke ukuthi imakethe izogcina umkhuba wokuhlanganiswa obuthakathaka esikhathini esifushane.
Isikhathi sokuthunyelwe: Septhemba 15-2025
