Ekuqaleni kuka-Epreli, kwiveki nje enye, ixabiso lemarike le-cyclohexanone linyuke ngama-900 yuan/ton. Zininzi izizathu zoku kunyuka oku. Ingaba umbono wemarike ungaqhubeka nokunyuka kuyaxhalabisa na.

Ukususela nge-30 kaMatshi, ixabiso lemarike le-cyclohexanone liphinde landa kakhulu. Ixabiso lemarike le-cyclohexanone eMpuma China liye lafumana ukunyuka okuthathu ukusuka kwi-9,450 yuan/ton. Ukusukela ekupheleni kwe-7 ka-Epreli, ixabiso lemarike le-cyclohexanone eMpuma China liye landa laya kwi-10,350 yuan/ton. . Ngoko makhe sihlalutye amaxesha ee-waves ezintathu ezilandelayo zokunyuka kwamaxabiso: igagasi lokuqala, nge-30 kaMatshi, linyuse i-200 yuan/ton. Isizathu sibangelwa kukunqongophala kokunikezelwa kweempahla kwimarike. Ukuncipha kwemveliso yemihla ngemihla yeShandong Hualu Hengsheng; Isityalo saseChongqing Huafeng sivaliwe ngenxa yokulungiswa; Isityalo saseShanxi Yangmei Fengxi cyclohexanone sivaliwe kwaye iindaba zokugcinwa ziyaqaliswa, ukuhanjiswa kwemarike kuqinisiwe, ukunikezelwa kwefektri akuthandi ukuthengiswa, kwaye ixabiso le-cyclohexanone kwimarike yaseMpuma China linyuke nge-200 yuan/Ton ukuya kwi-9,650 yuan/ton; Igagasi lesibini, nge-1 ka-Epreli, ngokutsho kweZhuo Chuang Information, amaxabiso adweliswe yiSinopec ethengiswa nge-benzene ecocekileyo anyuke nge-150 yuan / ton, ukuphunyezwa kwe-6,500 yuan / ton, kwaye iFengxi yaqala ukonyusa iindleko zokugcina. I-cyclohexanone yaseMpuma China inyuke nge-300 yuan / ton ukuya kwi-9950; igagasi lesithathu, nge-6 ka-Epreli, ixabiso lokuthengiswa kwe-benzene ecocekileyo yeSinopec linyuswe kwakhona nge-200 yuan / ton, kwaye ukuphunyezwa kwe-6,700 yuan / ton, imeko yokuqina kwemarike ayizukutshintsha, kwaye iindleko ziya kunceda iPush, ixabiso lemarike ye-cyclohexanone linyukile kwakhona, kwaye ixabiso lemarike ye-cyclohexanone eMpuma China linyuke nge-400 yuan / ton ukuya kwi-10,350 yuan / ton. Ngokuphathelele inzuzo, umda wenzuzo ye-cyclohexanone nawo ubuye wabuya emva kwexabiso. Ngamafutshane, ukunyuka kwamaxabiso emarike ye-cyclohexanone kwelinye icala kunxulumene nenkxaso yemarike ye-benzene ecocekileyo, kwaye kwelinye icala, ayinakwahlulwa kwinkxaso yemfuno yemarike yefayibha yamakhemikhali.

Imarike ephambili ye-caprolactam ye-cyclohexanone yayisebenza kwinqanaba eliphezulu, kwaye yaqhubeka izinzile ngaphezulu kwe-85%. Imfuno yezinto ezikrwada yayiphezulu. Nangona kunjalo, isiqingatha seefektri eziphambili zokuthumela ngaphandle ze-cyclohexanone zahlaziywa, kwaye ukuhanjiswa kokujikeleza kwemarike kwaqiniswa.

Xa sijonga imbonakalo yemarike, ngokwembono yeendleko, ukufika kwe-benzene ecocekileyo kwizibuko eliphambili kusalinganiselwe. Ngokwengxelo yokuthunyelwa kwempahla, izibuko eliphambili lisaya kwindawo yokugcina impahla. Njengoko kusanda ukulungiswa nokugcinwa ngo-Epreli, kulindeleke ukuba umthwalo wokuqala weshishini ubuye wehle. Kwicala lemfuno, umthwalo wokuqala weshishini le-styrene kulindeleke ukuba wehle, kodwa emva kokuba iSinochem Quanzhou kunye neChina Sea Shell zifakwe kwimveliso, imfuno iyonke inyukile. Ke ngoko, i-benzene ecocekileyo isekwimeko entle, kwaye kufuneka kuqwalaselwe impembelelo yeendlela ze-styrene kwimarike. Kwicala lokubonelela, ukugcinwa kweHuafeng kulindeleke ukuba kuphele kungekudala, kwaye ukugcinwa kwesixhobo saseYangmei Fengxi kulindeleke ukuba kuthathe ubuncinane iintsuku ezingama-20, kwaye kulindeleke ukuba siqalise kwakhona imveliso yomthwalo opheleleyo emva kokuphela kukaMeyi; isixhobo saseHualu Hengsheng silayishiwe kwaye ixesha lokubuyisela liza kumiselwa. Ngokuphathelele imfuno, isityalo sesibini se-caprolactam saseShandong Haili sicwangciselwe ukuqala nge-10 ka-Epreli (exhasayo). Ukususela nge-15 ka-Epreli, i-caprolactam yaseCangzhou Xuyang Chemical icwangciselwe ukuhlaziywa kangangeentsuku ezili-10 (exhasayo), kwaye nge-20 ka-Epreli, iFujian Yongrong Technology, iNanjing Dongfang, yema ngokulandelelana ukuze ilungiswe, kwaye ilungiswe iintsuku ezisi-7 kunye neentsuku ezingama-40 ngokulandelelanayo. Ukongeza, malunga ne-20 ka-Epreli, uYangmei Fengxi kulindeleke ukuba aqalise umthwalo ophantsi ukuze azalise ukunikezelwa kwemarike. Kulindeleke ukuba ukunikezelwa okuncinci kwe-cyclohexanone kuqhubeke ubuncinane kude kube yi-20 ka-Epreli kwaye kuqale ukuthomalalisa. Ke ngoko, ngesishwankathelo, i-cyclohexanone Ukunyuka kwamaxabiso emarike kuya kuhlala ubuncinane kude kube sekupheleni kuka-Epreli, kwaye ulinde kwaye ubone impembelelo yotshintsho kwimarike ye-benzene ecocekileyo kwi-cyclohexanone.
