Emva koMnyhadala weNtwasahlobo, uxinzelelo lokulahleka kweshishini le-phenol ketone lwehla, lwaze lwafumana nenzuzo embindini nasekupheleni kukaFebruwari. Nangona kunjalo, ngoMatshi, ixabiso le-phenol ketone labuya kancinci, ngelixa ixabiso lanyuka, kwaye ishishini laphinda lawa. Emva kwemini, ukunikezelwa kwe-phenol ketone kuzinzile kwaye kuncinci, nangona ishishini lizimisele ukuxhasa ixabiso linamandla, kodwa imfuno ayanelanga okanye ayithinteli ukunyuka kwemarike, imeko yokulahlekelwa lishishini kunzima ukuyitshintsha.
Ukuqalisa kwakhona isixhobo kufikelele kwimarike
Umhlalutyi uJin Lianchuang uBian Chenhui wazisa, ngaphambi kweholide yeSpring Festival, iimarike zasekhaya zephenol ketone kunye nephenol bezifudumala, zivaliwe kancinci kancinci. Kamva, ngenxa yempembelelo yezinto ezifana nesixa esincinci sesongezelelo kwiikhontrakthi zokungenisa impahla kunye nokwanda kophando lwemarike oluvela kubathumeli ngaphandle, imakethi yabuyela kwimeko yesiqhelo, kwaye ixabiso lephenol lenyuka ukusuka ngaphezulu kwe-7000 yuan (ixabiso leetoni, elifana nelingezantsi) ngaphambi kweSpring Festival ukuya ngaphezulu kwe-8000 yuan, laza lehla laya kutsho malunga ne-7950 yuan. Ixabiso le-acetone ukusuka kwi-5000 yuan lanyuka laya kwi-6150 yuan.
Ngaphambili, ukuzaliswa kwakhona kwempahla ye-phenol engeniswe eTshayina ngoFebruwari bekunganelanga, kwaye ukuzaliswa kwakhona kwempahla egciniweyo eJiangyin yayikumthwalo wasekhaya ikakhulu, okwakunempembelelo encinci ekunikezelweni kwempahla kwangoko kwimarike. Ukongeza, xa kujongwa ulindelo lomsebenzi wokuthunyelwa kwamanye amazwe, uxinzelelo lokuthunyelwa kwempahla kwicala lokubonelela alukho kangako, nto leyo enyusa imvakalelo. Nangona kunjalo, ukungqubana phakathi kokunikezelwa kwempahla kunye nemfuno kwimarike akunciphisanga ngempumelelo, kwaye ukunyuka kwemarike ye-phenolic ketone akwanelanga kakhulu.
Okwangoku, iYangzhou Shiyou ixabisa iitoni ezingama-320,000/isixhobo sephenolone sonyaka kwaye yaqala ukuvuselelwa; ukucoca iShenghong kusebenze kakubi, kwaye izinga lokusebenza linyuswe kufutshane ne-84%. Njengoko ixabiso lephenolone litshintsha tshintsha kwinqanaba eliphezulu, indawo yabavelisi yaqhubeka nokuncipha, kwaye ekupheleni kukaFebruwari, yaguqula ilahleko yaba yinzuzo, eyayisondele kwi-150 yuan. Okwangoku, njengoko ixabiso liye lehla, kwaye izinto ezisetyenzisiweyo ziphezulu, ilahleko yeemveliso zephenolone iphantse ibe yi-300 yuan ngetoni.
Ngokwembono yemarike, iingenelo ezibangelwa kukufakelwa kwendawo yokupaka nokulungisa ziyaphela kancinci kancinci. Isixhobo seJiangsu Ruiheng Phenol siza kuqaliswa kwakhona kungekudala siya kuba nefuthe kwimarike. Imarike yephenolone inokuqhubeka nokusebenzisa uxinzelelo kwaye iguqule ilahleko ibe bubunzima.
Ixabiso lezinto eziluhlaza liphezulu
Ngokwembono yezinto eziluhlaza ezikumgangatho ophezulu, ixabiso le-benzene ecocekileyo liqhubekile nokunyuka. Okwangoku, ixabiso lentengiselwano yesithuba liyi-250-350 yuan xa kuthelekiswa nokuphela kukaFebruwari, enye yezinto ezibalulekileyo ezibangela ilahleko kwishishini le-phenolone.
UZhang Wei, umhlalutyi weLongzhong Information, uxele ukuba olu nyuko lubangelwa kakhulu kukuncitshiswa kweempahla ezingeniswayo. Impahla ecocekileyo ye-benzene yase-East China Port okwangoku imalunga neetoni ezingama-265,000, ukwehla kwe-1.3% ngenyanga ngenyanga. Kutshanje, ixesha lokuthumela eHong Kong liye lehla xa kuthelekiswa nenqanaba lokuqala. Ukongeza, ixabiso elidwelisiweyo leyunithi ephambili linyusiwe, impahla yeShandong iphantsi, kwaye abanye abadlali beli shishini bathenga ngenkuthalo unikezelo.
Ngokwembono yemarike yemarike, i-oyile ekrwada yamazwe ngamazwe yakutshanje iyatshintshatshintsha, kwaye idiski yangaphandle yebenzene ecocekileyo iyaqhubeka nokuvala, kodwa ixabiso le-colone esezantsi linyukile emva kokuwa, nto leyo ebekwe ngaphezulu kwexabiso lebenzene ecocekileyo yeSinopec.
Emva kokungena ngoMatshi, kwaphuma enye into eluhlaza kwimo "ye-V", kodwa inkxaso esisiseko eluncedo yayincinci, kwaye indawo ekhulayo kwimarike yayingenkulu. Izinto ezixhasa ukubuyela kwakhona kwimarike ikakhulu kukupaka kwisixhobo se-blonde se-Liaoning. Isixhobo se-overlaying individual propine dehydrogenation (PDH) sinciphile, kwaye umthamo wangaphandle osebenzayo we-acryline unciphile. Ukongeza, inzuzo ye-chlorol oxide (PO) iphucuke kakhulu, amanye amashishini e-chlorol emveli andise umthwalo, kwaye isixhobo se-Jishen PO sikwanaso nesicwangciso sokuvuselela. Isiphumo esibanzi sezi zinto sinyuse umdla wokuthengwa kwepropely.
Umthengisi wePetrochemical uJilin uHe Junsong uxele ukuba njengoko ixabiso le-acrylic liqhubeka linyuka, imarike ayinanjongo yokuqhubeka nokusukela phezulu, kwaye intengiselwano yemarike ayifikeleleki. Nangona kunjalo, xa kujongwa ukuncitshiswa kwezixhobo zokungena kwe-acrylic ezilandelayo kunye nokubakho kwamanqaku amatsha emfuno, umngcipheko we-acrylonitris awukhulu, kwaye kulindeleke ukuba imakethi itshintshe kuluhlu oluncinci.
Imfuno ebuthathaka ayincedi kangako ekuyiphakamiseni
Imakethi ephambili ye-bisphenol A esezantsi iye yehla kancinci. Emva kokubuya konyaka, imfuno yokugqibela ayilunganga njengoko bekulindelwe. Uxinzelelo olusezantsi luyaphazamiseka, ukusetyenziswa kwe-bisphenol A kancinci kancinci, kwaye kucinezela ingqondo yeshishini.
UWang Chunming, umphathi jikelele weShandong Ruiyang Chemical Co., Ltd., uthe njengoko ixabiso le-bisphenol A lihla liyehla, bekukho inani elincinci lee-odolo ezincinci kwimarike ezibuza, kodwa injongo yokuhambisa idiski yayiphantsi, kwaye imakethi yemarike ayonelanga. Izinga lokusebenza kwezinye izixhobo ze-bisphenol A liye lehla kancinci, kodwa ukubonelelwa kweemarike ezikwindawo ethile kusanele. Ukongeza, isixhobo esitsha se-Guangxi Huayi bisphenol A sifakwa ngempumelelo kwimveliso, amandla emveliso yasekhaya ayanda, nto leyo eyonyusa ingqondo yobulumko nengenanto kwishishini.
Ngokwembono yemarike yemarike, imfuno ye-bisphenol A ayinkulu, kwaye imakethi isekelwe kakhulu ekuthengweni okuncinci okufuneka kube kanye. Ukongeza, phantsi koxinzelelo lokulahlekelwa, izinga lokusebenza kwe-bisphenol A linokuncipha ngakumbi. Ngelo xesha, ukuthengwa kwezinto eziluhlaza kunzima ukuxhasa ukunyuka okuphezulu kwemarike ye-phenolone.
