Ekuqaleni kuka-Ephreli, ngesonto elilodwa nje, intengo yemakethe ye-cyclohexanone yehle ngama-yuan angu-900/ton. Kunezizathu eziningi zalokhu kwenyuka. Imakethe ikhathazekile ngokuthi umbono wemakethe ungaqhubeka yini nokukhuphuka.

Kusukela ngoMashi 30, intengo yemakethe ye-cyclohexanone ikhuphuke kakhulu. Intengo yemakethe ye-cyclohexanone eMpumalanga China ibhekane namagagasi amathathu okunyuka kusuka ku-9,450 yuan/ton. Kusukela ekupheleni kuka-Ephreli 7, intengo yemakethe ye-cyclohexanone eMpumalanga China ikhuphuke yaya ku-10,350 yuan/ton. . Ngakho-ke ake sihlaziye ama-node esikhathi samagagasi amathathu alandelayo okunyuka kwentengo: igagasi lokuqala, uMashi 30, lakhuphuka ngama-yuan angu-200/ton. Isizathu sibangelwa kakhulu ukunikezwa okuncane kwezimpahla emakethe. Ukwehla komkhiqizo wansuku zonke kweShandong Hualu Hengsheng; Isitshalo saseChongqing Huafeng sivaliwe ngenxa yokulungiswa; Isitshalo saseShanxi Yangmei Fengxi cyclohexanone sivaliwe futhi izindaba zokugcinwa ziyaqaliswa, ukusatshalaliswa kwemakethe kuqinisiwe, ukusatshalaliswa kwefektri akuthandi ukuthengisa, futhi intengo ye-cyclohexanone emakethe yaseMpumalanga China ikhuphuke ngama-yuan angu-200/ton yaya ku-9,650 yuan/ton; igagasi lesibili, mhla lu-1 kuMbasa, ngokusho kweZhuo Chuang Information, ukuthengiswa kwe-Sinopec kwe-benzene emsulwa kukhuphuke ngo-150 yuan/ton, ukusetshenziswa kwama-yuan angu-6,500/ton, kwathi iFengxi yaqala ukukhulisa izindleko zokulungisa. I-cyclohexanone yaseMpumalanga China ikhuphuke ngo-300 yuan/ton yaya ku-9950; igagasi lesithathu, mhla lu-6 kuMbasa, intengo yokuthengiswa kwe-benzene emsulwa yeSinopec yaphakanyiswa futhi ngo-200 yuan/ton, kanye nokusetshenziswa kwama-yuan angu-6,700/ton, isimo sokuqina kwemakethe ngeke sishintshe, futhi izindleko zizosiza i-Push, intengo yemakethe ye-cyclohexanone ikhuphuke futhi, kanti intengo yemakethe ye-cyclohexanone eMpumalanga China ikhuphuke ngo-400 yuan/ton yaya ku-10,350 yuan/ton. Ngokuphathelene nenzuzo, inzuzo ye-cyclohexanone nayo ibuyile ngemuva kwentengo. Ngamafuphi, ukwenyuka kwentengo yemakethe ye-cyclohexanone ngakolunye uhlangothi kuhlobene nokusekelwa kwemakethe ye-benzene emsulwa, kanti ngakolunye uhlangothi, akuhlukaniseki nokusekelwa kwesidingo semakethe yefayibha yamakhemikhali.

Imakethe enkulu ye-cyclohexanone engezansi ye-caprolactam yayisebenza ezingeni eliphezulu, futhi yaqhubeka nokuzinza ngaphezu kwama-85%. Isidingo sezinto zokusetshenziswa sasiphezulu. Kodwa-ke, ingxenye yezimboni ezinkulu zokuthumela ngaphandle ze-cyclohexanone yavuselelwa, futhi ukuhanjiswa kokujikeleza kwemakethe kwaqiniswa.

Uma sibheka umbono wemakethe, ngokombono wezindleko, ukufika kwe-benzene emsulwa echwebeni elikhulu kusalinganiselwe. Ngokombiko wokuthumela, ichweba elikhulu lisaya endaweni yokugcina impahla. Njengoba ukwanda kokugcinwa nokulungiswa kukhule ngo-Ephreli, umthwalo wokuqala embonini kulindeleke ukuthi wehle futhi. Ohlangothini lwesidingo, umthwalo wokuqala embonini ye-styrene kulindeleke ukuthi wehle, kodwa ngemuva kokuthi i-Sinochem Quanzhou ne-China Sea Shell zifakwe ekukhiqizweni, isidingo sonke sikhulile. Ngakho-ke, i-benzene emsulwa isesesilinganisweni esiqinile, futhi kudingeka kuqashelwe umthelela wezitayela ze-styrene emakethe. Ohlangothini lokuphakelwa, ukulungiswa kwe-Huafeng kulindeleke ukuthi kuphele maduze nje, futhi ukulungiswa kwedivayisi ye-Yangmei Fengxi kulindeleke ukuthi kuthathe okungenani izinsuku ezingama-20, futhi kulindeleke ukuthi kuqale kabusha ukukhiqizwa komthwalo ogcwele ngemuva kokuphela kukaMeyi; idivayisi ye-Hualu Hengsheng ilayishiwe phansi futhi isikhathi sokutakula sizonqunywa. Ngokuphathelene nesidingo, isitshalo sesibili se-caprolactam saseShandong Haili sihlelwe ukuqala ngomhlaka-10 kuMbasa (osekelayo). Kusukela ngomhlaka-15 kuMbasa, i-caprolactam yaseCangzhou Xuyang Chemical ihlelelwe ukulungiswa kabusha izinsuku ezingaba yi-10 (osekelayo), kanti ngomhlaka-20 kuMbasa, iFujian Yongrong Technology, iNanjing Dongfang, ima ngokulandelana ukuze ilungiswe kabusha, futhi ilungiswe kabusha izinsuku eziyi-7 nezinsuku ezingama-40 ngokulandelana. Ngaphezu kwalokho, cishe ngomhlaka-20 kuMbasa, kulindeleke ukuthi iYangmei Fengxi iqale umthwalo ophansi ukuze igcwalise ukunikezwa kwemakethe. Kulindeleke ukuthi ukunikezwa okuncane kwe-cyclohexanone kuzoqhubeka okungenani kuze kube umhlaka-20 kuMbasa bese kuqala ukudamba. Ngakho-ke, ngamafuphi, i-cyclohexanone Umkhuba okhulayo wamanani emakethe uzohlala okungenani kuze kube sekupheleni kukaMbasa, futhi ulinde futhi ubone umthelela wezinguquko emakethe ye-benzene emsulwa ku-cyclohexanone.
