Ngemva koMkhosi waseNtwasahlobo, ingcindezi yokulahlekelwa yimboni ye-phenol ketone yehla, yaze yathola inzuzo maphakathi nasekupheleni kukaFebhuwari. Kodwa-ke, ngoMashi, intengo ye-phenol ketone yehla kancane, kuyilapho izindleko zikhuphuka, futhi imboni yaphinde yawa. Ntambama, ukunikezwa kwe-phenol ketone kuzinzile futhi kuncane, yize imboni izimisele ukusekela intengo inamandla, kodwa isidingo asanele noma sinciphise ukukhuphuka kwemakethe, isimo sokulahlekelwa yimboni kunzima ukusishintsha.
Ukuqala kabusha idivayisi kufinyelele emakethe
Umhlaziyi uJin Lianchuang uBian Chenhui wethule, ngaphambi kweholide leSpring Festival, izimakethe zasekhaya ze-phenol ketone kanye ne-phenol bezilokhu zifudumele, zivaliwe kancane kancane. Kamuva, ngenxa yethonya lezici ezifana nenani elincane lesengezo ezinkontilekeni zokungenisa kanye nokwanda kophenyo lwemakethe oluvela kubathumeli, imakethe yalulama kancane kancane, futhi intengo ye-phenol yakhuphuka isuka kuma-yuan angaphezu kuka-7000 (intengo yamathani, efanayo ngezansi) ngaphambi kweSpring Festival yaya kuma-yuan angaphezu kuka-8000, yabe seyehla yaya kuma-yuan angaba ngu-7950. Intengo ye-acetone isuka kuma-yuan angu-5000 yakhuphukela kuma-yuan angu-6150.
Ngaphambilini, ukugcwaliswa kabusha kwempahla ye-phenol engenisiwe eShayina ngoFebhuwari kwakunganele, futhi ukugcwaliswa kabusha kwezimpahla ezigciniwe eJiangyin kwakuwumthwalo wasekhaya ikakhulukazi, okwakungenawo umthelela omkhulu ekuhlinzekweni kwempahla emakethe. Ngaphezu kwalokho, uma kucatshangelwa ukulindela kokusebenza kokuthunyelwa kwamanye amazwe, ingcindezi yokuthunyelwa kohlangothi lokunikezwayo ayiningi, okuqhubekisela phambili lo mbono. Kodwa-ke, ukuphikisana phakathi kokunikezwa nesidingo emakethe akukancishiswa ngempumelelo, futhi umfutho okhuphukayo wemakethe ye-phenolic ketone awanelanga kangako.
Njengamanje, i-Yangzhou Shiyou ibiza amathani angu-320,000/idivayisi ye-phenolone yonyaka futhi; ukucwengisisa i-Shenghong kunomsebenzi omubi, futhi izinga lokusebenza likhushulwe cishe ngo-84%. Njengoba intengo ye-phenolone ishintshashintsha ezingeni eliphezulu, isikhala sabakhiqizi saqhubeka nokuncipha, kwathi ekupheleni kukaFebhuwari, kwaphenduka ukulahlekelwa kwaba yinzuzo, okwakucishe kube yi-yuan engu-150. Njengamanje, njengoba intengo yehlile, futhi izinto zokusetshenziswa zikhuphuka, ukulahlekelwa kwemikhiqizo ye-phenolone kucishe kube yi-yuan engu-300 ngethani.
Ngokombono wemakethe, izinzuzo ezilethwa ukufakwa kwendawo yokupaka nokulungisa ziyanyamalala kancane kancane. Idivayisi ye-Jiangsu Ruiheng Phenol izoqalwa kabusha maduze izoba nomthelela emakethe. Imakethe ye-phenolone ingaqhubeka nokusebenzisa ingcindezi futhi iguqule ukulahlekelwa kube ubunzima.
Intengo yezinto zokusetshenziswa iphezulu
Ngokombono wezinto zokusetshenziswa ezikhuphukayo, intengo ye-benzene emsulwa iqhubekile nokukhuphuka. Njengamanje, intengo yokuthengiselana kwe-spot ingu-250-350 yuan uma kuqhathaniswa nokuphela kukaFebhuwari, okungenye yezinto ezibalulekile ezibangela ukulahlekelwa embonini ye-phenolone.
UZhang Wei, umhlaziyi weLongzhong Information, wethule ukuthi lokhu kwanda kubangelwa kakhulu ukuncipha kwezimpahla ezingeniswayo. Impahla ehlanzekile ye-benzene yase-East China Port okwamanje ingamathani angaba ngu-265,000, ukwehla ngo-1.3% ngenyanga. Muva nje, isikhathi sokuthumela eHong Kong sehlile uma kuqhathaniswa nesigaba sokuqala. Ngaphezu kwalokho, intengo ebhalwe ohlwini yeyunithi eyinhloko iphakanyisiwe, impahla yempahla yaseShandong iphansi, futhi abanye abadlali bemboni bathenga ngenkuthalo ukunikezwa.
Ngokombono wemakethe yemakethe, uwoyela ongahluziwe wamazwe ngamazwe muva nje uyashintshashintsha, kanti idiski yangaphandle ye-benzene emsulwa iyaqhubeka nokuvala, kodwa intengo ye-colone engezansi inyukile ngemva kokuwa, okubekwe phezu kwentengo ye-benzene emsulwa ye-Sinopec.
Ngemva kokungena ngoMashi, kwaphuma enye into eluhlaza ngesimo "se-V", kodwa ukwesekwa okuyisisekelo okuhle kwakulinganiselwe, futhi isikhala esikhulayo semakethe sasingesikhulu. Izici ezisekela ukubuyela emuva kwemakethe ikakhulukazi ukupaka kudivayisi ye-blonde ye-Liaoning. Idivayisi ye-propine dehydrogenation (PDH) embozwe ngaphezulu incishisiwe, futhi ivolumu yangaphandle esebenzayo ye-acryline inciphile. Ngaphezu kwalokho, inzuzo ye-chlorol oxide (PO) ithuthuke kakhulu, amanye amabhizinisi e-chlorol endabuko andise umthwalo, kanti nedivayisi ye-Jishen PO nayo inohlelo lokuvuselela. Umphumela ophelele walezi zici ukhulise intshiseko yokuthengwa kwe-propely.
Umthengisi we-Petrochemical uJilin He Junsong wethule ukuthi njengoba intengo ye-acrylic iqhubeka nokukhuphuka, imakethe ayinaso isifiso sokuqhubeka nokujaha okuphezulu, futhi ukuthengiselana kwemakethe kuvaliwe. Kodwa-ke, uma kucatshangelwa ukwehla kwezinsizakusebenza ze-acrylic ezilandelayo kanye nokuba khona kwamaphuzu amasha okufunwa, izingozi ze-downlink ze-acrylonitris azinkulu, futhi imakethe kulindeleke ukuthi ishintshe ibanga elincane.
Isidingo esibuthakathaka asikwenzi lutho ukuyiphakamisa
Imakethe eyinhloko ye-bisphenol A eyehla kancane kancane. Ngemva kokubuya onyakeni, isidingo sokugcina asisihle njengoba bekulindelekile. Ukushaqeka okuphansi kwe-bisphenol A kuyehla kancane kancane, futhi kucindezela ingqondo yemboni.
UWang Chunming, umphathi jikelele weShandong Ruiyang Chemical Co., Ltd., uthe njengoba intengo ye-bisphenol A yehla, kwakukhona inani elincane lama-oda amancane emakethe abuza, kodwa inhloso yokunikeza idiski yayiphansi, futhi imakethe yemakethe ayanele. Izinga lokusebenza kwamanye amadivayisi e-bisphenol A lehle kancane, kodwa ukunikezwa kwezimakethe eziqondile kusanele. Ngaphezu kwalokho, idivayisi entsha ye-Guangxi Huayi bisphenol A ifakwa ngempumelelo ekukhiqizweni, amandla okukhiqiza asekhaya ayanda, okwenza kube nzima ukucabanga okuqaphile nokungenalutho embonini.
Ngokombono wemakethe yemakethe, isidingo se-bisphenol A asisikhulu, futhi imakethe isekelwe kakhulu ekuthengweni okuncane okudingekayo kanye. Ngaphezu kwalokho, ngaphansi kwengcindezi yokulahlekelwa, izinga lokusebenza le-bisphenol A lingancishiswa kakhulu. Ngaleso sikhathi, ukuthengwa kwezinto zokusetshenziswa kunzima ukusekela ukukhuphuka okuphezulu kwemakethe ye-phenolone.
