Emva koMthendeleko we-Spring, uxinzelelo lwe-phenol ketone ilahleko yoshishino lwehla, kwaye yade yajika inzuzo phakathi nasekupheleni kukaFebruwari.Nangona kunjalo, ngo-Matshi, ixabiso le-phenol ketone libuyiselwe kancinci, ngelixa ixabiso liqhubekile, kwaye imboni yawela ebomvu kwakhona.Emva kwemini, ukunikezelwa kwe-phenol ketone kuzinzile kwaye kuncinci, nangona imboni izimisele ukuxhasa ixabiso elinamandla, kodwa imfuno ayikwanelanga okanye ukunciphisa ukunyuka kweemarike, imeko yokulahlekelwa kweshishini kunzima ukuyitshintsha.
Ukuqalisa kwakhona isixhobo kubetha imarike
Umhlalutyi we-Jin Lianchuang u-Bian Chenhui wazisa, ngaphambi kweholide yoMnyhadala weNtwasahlobo, i-phenol ketone yasekhaya kunye neemarike ze-phenol bezidikidiki, zavalwa ngokuthe ngcembe.Kamva, ngenxa yempembelelo yezinto ezinje ngexabiso elincinci lokongezelela kwiikontraka zokungenisa elizweni kunye nokwanda kophando lwemarike kubathengisi abathumela ngaphandle, imarike ngokuthe ngcembe yaphinda yachacha, kwaye ixabiso le-phenol lenyuka ukusuka ngaphezulu kwe-7000 yuan (ixabiso letoni, elifanayo ngezantsi. ) phambi koMthendeleko waseNtwasahlobo ukuya ngaphezulu kwe-8000 yeyuan, emva koko yawela malunga ne-7950 yuan.Ixabiso le-acetone ukusuka kwi-5000 ye-yuan lityhale ukuya kuma-6150 yuan.
Ngaphambili, ukuzaliswa kwempahla ye-phenol evela kumazwe angaphandle e-China ngoFebruwari kwakunganelanga, kwaye ukuzaliswa kwempahla egciniweyo e-Jiangyin yayiyimpahla yasekhaya, eyayinempembelelo encinci ekuboneleleni kwendawo kwimarike.Ukongeza, ukuqwalasela ukulindela umsebenzi wokuthunyelwa kwamanye amazwe, uxinzelelo lokuthunyelwa kwecala lokubonelela aluninzi, olunyusa uvakalelo.Nangona kunjalo, ukuchasana phakathi kokubonelela kunye nemfuno kwimarike akuzange kuncitshiswe ngokufanelekileyo, kwaye ukunyuka kwemarike ye-phenolic ketone akwanelanga kakhulu.
Okwangoku, iYangzhou Shiyou 320,000 yeetoni / isixhobo sonyaka sephenolone siphinde saqala ukubuyisela;Ukucokisa i-Shenghong kunomsebenzi ongalunganga, kwaye izinga lokusebenza linyuswe kufutshane ne-84%.Njengoko ixabiso le-phenolone liguquguquka kwizinga eliphezulu, indawo yabavelisi yaqhubeka iyancipha, kwaye ekupheleni kukaFebruwari, yajika ilahleko kwinzuzo, eyayisondele kwi-yuan eyi-150.Okwangoku, njengoko ixabiso liwile, kunye nezinto ezikrwada ziphezulu, ilahleko yeemveliso zephenolone iphantse ibe ngama-yuan angama-300 ngetoni nganye.
Ngokwembono yemarike, izibonelelo eziziswa ngokufakela indawo yokupaka kunye nokugcinwa ngokuthe ngcembe ziphela.Isixhobo se-Jiangsu Ruiheng Phenol siza kuqaliswa kwakhona siya kuba nefuthe kwintengiso.Imarike ye-phenolone inokuqhubeka nokusebenza uxinzelelo kwaye iguqule ilahleko ibe nzima.
Ixabiso lempahla ekrwada liphezulu
Ukusuka kwimbono yemathiriyeli ekrwada ephezulu, ixabiso le-benzene ecocekileyo liqhubekile nokunyuka.Okwangoku, ixabiso lokuthengiselana kwendawo yi-250-350 yuan xa kuthelekiswa nokuphela kukaFebruwari, enye yezinto ezibalulekileyo ezibangela ilahleko kwishishini le-phenolone.
UZhang Wei, umhlalutyi weLongzhong Information, wazisa ukuba oku kunyuka kubangelwa ikakhulu kukuncipha kwempahla evela ngaphandle.Uluhlu lwe-benzene olusulungekileyo lwase-East China Port okwangoku lumalunga neetoni ezingama-265,000, ukuhla nge-1.3% ngenyanga-ngenyanga.Kutshanje, ixesha lokuthumela ngenqanawa ukuya eHong Kong lehlile xa lithelekiswa nenqanaba lokuqala.Ukongeza, ixabiso elidwelisiweyo leyunithi ephambili liphakanyisiwe, uluhlu lweempahla lweShandong luphantsi, kwaye abanye abadlali beshishini bathenga ngokunyanisekileyo ukubonelela.
Ngokwembono yemarike, i-oyile ekrwada yamva nje iyaguquguquka, kwaye i-benzene yangaphandle yediski iyaqhubeka nokuvala, kodwa ixabiso le-colomorne esezantsi liphezulu emva kokuwa, elibekwe ngaphezulu ngexabiso le-benzene ecocekileyo yeSinopec.
Emva kokungena ngoMatshi, enye into ekrwada yaphuma kwimilo "V", kodwa inkxaso yenkxaso esisiseko yayilinganiselwe, kwaye indawo yokunyuka kweemarike yayingenkulu.Izinto ezixhasa ukuphindaphindwa kweemarike kukupaka ikakhulu kwisixhobo se-Liaoning blonde.Ukugqithiswa kwesixhobo sepropine dehydrogenation (PDH) sincitshisiwe, kwaye umthamo wangaphandle osebenzayo we-acryline unciphile.Ukongezelela, inzuzo ye-chlorol oxide (PO) iphuculwe kakhulu, ezinye iinkampani ze-chlorol zendabuko ziye zanda umthwalo, kwaye isixhobo se-Jishen PO sinesicwangciso sokuvuselela.Isiphumo esibanzi sezi zinto sikhulise umdlandla wokuthengwa kwempahla ngokukhawuleza.
UJilin Petrochemical Salesman He Junsong wazisa ukuba njengoko ixabiso le-acrylic liqhubeka nokunyuka, i-downstream ayinayo injongo yokuqhubeka nokuxosha phezulu, kwaye ukuthengiswa kweemarike kuphelile.Nangona kunjalo, ngokuqwalasela ukunciphisa i-acrylic elandelayo imithombo engenayo kunye nobukho bamanqaku amatsha afunwayo, iingozi ze-downlink ze-acrylonitris azinkulu, kwaye imarike kulindeleke ukuba iguqule uluhlu oluncinci.
Imfuno ebuthathaka yenza kancinci ukuyiphakamisa
Imakethi engundoqo yebisphenol A iwile ngokubuthathaka.Emva kokubuya enyakeni, imfuno yesiphelo ayikho kakuhle njengoko bekulindelekile.Izothuso ezisezantsi zomsinga, ukusetyenziswa kwe-bisphenol A kancinci, kwaye kucinezela ingqondo yeshishini.
U-Wang Chunming, umphathi jikelele we-Shandong Ruiyang Chemical Co., Ltd., wathi njengoko ixabiso le-bisphenol A lehla liphantsi, kwakukho inani elincinci lee-odolo ezincinci kwiimarike ezibuzayo, kodwa injongo yokuhambisa idiski yayiphantsi, kwaye imarike yemarike yayingonelanga.Umyinge wokusebenza kwezinye izixhobo ze-bisphenol A wehle kancinci, kodwa unikezelo lweemarike zendawo lusanele ngokwaneleyo.Ukongeza, isixhobo esitsha se-Guangxi Huayi bisphenol A sifakwe ngempumelelo kwimveliso, amandla okuvelisa asekhaya ayanda, nto leyo ekhulisa ingqondo elumkileyo kunye nengenanto yoshishino.
Ngokwembono yemarike, imfuno ye-bisphenol A ayinkulu, kwaye imakethi isekwe ikakhulu kukuthengwa okuncinci okufunekayo.Ukongezelela, phantsi koxinzelelo lwelahleko, izinga lokusebenza kwe-bisphenol A lingancitshiswa ngakumbi.Ngelo xesha, ukuthengwa kwezinto ezithengiswayo kunzima ukuxhasa ukunyuka okuphezulu kwemarike ye-phenolone.
