Ukusukela ngoFebruwari, i-polymerization yasekhaya ye-diphenyl methane diisocyanate (MDI) yotsalo lwemarike Yin phantsi, kodwa amaxabiso ezinto ezikrwada anyuka ngakumbi nangaphantsi, njenge-20 kaFebruwari kwingingqi yaseShandong i-aniline yavuka i-yuan eyi-1000 (ixabiso letoni, efanayo ngezantsi)."Inkxaso yokuphela kweendleko ixhasa imfuno emandla esezantsi kancinci kancinci, okanye iya kukhupha imakethi ye-MDI ngaphandle kwemeko enzima, ivule intengiso."Abantu abaninzi kushishino benze olu phando lungentla kunye nesigwebo.
Inkxaso yeendleko ezinamandla
Imathiriyeli ekrwada i-aniline yenza i-75% yeendleko ze-MDI.Kutshanje, ixabiso le-aniline liyenyuka, kwaye inkxaso yeendleko ze-MDI iyaqiniswa.
Ukuza kuthi ga kwi-21 kaFebruwari, ixabiso lemarike ye-aniline yaseNyakatho ye-China yayiyi-yuan eyi-12,200, inyuke ngo-1950 yuan xa kuthelekiswa ne-28 kaJanuwari, ukunyuka kwe-19.12%;Ukusukela nge-17 kaFebruwari, ukunyuka kwe-1200 yuan, okanye i-10.96%.
“Ukunyuka kabukhali kwimarike yeaniline kubangelwa ikakhulu kukwanda kweodolo ephakathi nasezantsi.Imfuno ye-aniline inyukile, kwaye inani leeyunithi zemveliso ziya kuvalwa ukuze zigcinwe, ukuzithemba kwimarike kunyusiwe, abavelisi bakhawuleza behlisa isitokhwe, kwaye ixabiso le-aniline linyuke kakhulu. ”Shandong Kenli Petrochemical Group injineli eyintloko uWang Quanping uhlalutyo uthe.
Okwangoku, i-Nanhua imise i-100,000 yeetoni / isixhobo sonyaka we-aniline;I-Chongqing BASF I-300,000 yeetoni / iplani yokufaka isicwangciso sonyaka, ekulindeleke ukuba ihlale inyanga ye-1;Ningbo Wanhua 720,000 iitoni / ngonyaka isixhobo 50% umsebenzi umthwalo.
Ukusuka kwindawo yokujonga i-aniline phezulu, imakethi ye-benzene ecocekileyo yasekhaya izothuswa ngamandla.I-East China ezantsi ukuphunyezwa okusebenzayo kwee-odolo zokuhanjiswa, i-inventory ye-port yehle kancinane.Imakethi ye-benzene ecocekileyo yase-United States yenyuka, ixabiso langaphandle lenyuka, ixabiso lasekhaya le-benzene ecocekileyo "concave", umnikazi wemva kwemini engaphezulu.
Ngaphambi kokuba ixabiso le-aniline lingenyuki, i-avareji yengeniso ye-polymerization yasekhaya ye-MDI factory yayimalunga ne-3273 yuan.Ukunyuka kwemathiriyeli ekrwada ngokuqinisekileyo kuya kucinezela indawo yenzuzo ye-polymerization MDI, konyusa ukuzimisela kwabavelisi exabiso. ”U-Wang Quanping uthe kwimarike yasemva kwemini, ukunikezelwa kwe-aniline ngokucacileyo kuncitshisiwe, kwaye i-inventory inokuwela kwinqanaba eliphantsi.Kulindeleke ukuba ixabiso le-aniline liza kuqhubeka likhuphuka kwixesha elifutshane, lenze inkxaso ye-polymerized MDI market phambi kweendleko.
Banga ukulungiswa ngokwenyathelo
Njengepolymeric MDI imarike yepolyether esezantsi iphucuke kancinane mva nje.Iqhutywa yipropylene oxide njengento ekrwada, imarike yepolyether ivula indlela yokutsala.Phantse inyanga ye-1, ixabiso le-polyether lenyuka ngaphantsi, iziko lomxhuzulane, uMthendeleko weNtwasahlobo unyuke nge-800 yuan.
Ukusuka kwicala lokubonelela, i-polyether cargo yanele, kodwa owona mthombo uphambili wempahla ukugcina imeko iqinile.Iifektri ezinkulu kumntla nasezantsi zikulungele ukuxhasa imarike, kwaye ininzi yendawo yokusebenza yezityalo ze-polyether isanqatshelwe yi-propylene oxide.Ukongeza, abavelisi banoluhlu oluthile, kwaye emva koMthendeleko weNtwasahlobo, imarike yepropylene oxide ikwimeko eyothusayo, kwaye ixabiso loluhlu lweemveliso ezigqityiweyo aliphantsi.Kuqikelelwa ukuba ukulungelelaniswa okuphezulu kothutho yeyona nto iphambili kwixesha elizayo elingekude.
Kutshanje, ukungeniswa kweempahla kulindeleke ukuba kongezelele, kodwa isixa se-polyether ethambileyo ye-bubble incinci, owona mzi-mveliso wasekhaya unamathela kwisimo sengqondo sesixeko.Shandong Institute of ishishini kunye nolwazi Technology oonjingalwazi-level injineli eliphezulu Pan Jinsong uthe.
Ukususela kumbono wemfuno, umyalelo we-downstream ye-sponge yangaphakathi ye-odolo ye-sponge izinzile, kwaye ukusetyenziswa okuphambili kwezinto ezibonakalayo kumashishini okuvelisa kuya kubanjwa ngo-Matshi.Ngo-Matshi, umboniso wefenitshala uya kubanjwa, okanye uya kuzisa izibonelelo ezilungileyo kwimarike yezinto eziluhlaza.Umyalelo wamashishini ezipontshi zokuthumela ngaphandle ngokubanzi.YiNyanga yeLungu le-Amazon ngoJulayi.Kulindeleke ukuba ibe nendima ethile ekhokelayo ekuthengiseni ngaphandle-uhlobo lwamashishini esiponji emva kuka-Epreli.
Ukusuka kumbono wezinto ezikrwada, umhombiso osanda kufakwa kwi-oxide ye-oxide ngasekupheleni kukaFebruwari yi-satellite petrochemical kuphela, kunye nolindelo olulindelekileyo lwesixhobo se-Ida okanye ukuqaliswa kokuqaliswa kwakhona.Izixhobo eziseleyo azikho ukwanda okuphawulekayo okwangoku.Ngokupaka kwesigaba sokuqala seZhenhai Refining kunye neChemical, ukuthengiswa kweemarike akuphezulu, kwaye inkxaso yeendleko iphezulu.Kulindeleke ukuba amaxabiso e-oxide propyne athambekele ekunyukeni kwaye kunzima ukuhla, kwaye isaxhasa imarike yepolyether.
Lilonke, kukho imiqondiso yemfuno yokugqibela, eya kuqhuba i-MDI edibeneyo yemarike ukuba inyuke.
Kulindelwe ukucutheka konikezelo
Okwangoku, ukwehla kwemarike ye-MDI ehlanganisiweyo yasekhaya kuye kwacotha, kwaye ixabiso lonikezelo liyi-15,500 ~ 15,800 ye-yuan, kunye nexabiso lokunikezelwa kwempahla evela kumazwe angaphandle (MR200, M200) yi-15,300 ~ 15,600 ye-yuan.
“Okwangoku, ixabiso lokudityaniswa kwe-MDI lisekwinqanaba eliphantsi phantse kwiminyaka emithathu. Phantsi kwethemba lokuthintela ubhubhane kunye nemigaqo-nkqubo yolawulo kunye nolindelo lokubuyela kwimeko yesiqhelo kwezoqoqosho, imakethi ye-MDI ehlanganisiweyo inyuka kancinci ngokwamanqanaba.Ababoneleli batshintshisa ixesha lendawo kwaye ngokuthe ngcembe batyhalela phambili kulawulo lwentengiso ngokwesantya sokusetyenziswa ekupheleni kwemfuno. ”UPan Jinsong uthe.
Ukusuka kwicala lokubonelela, unikezelo lulinganiselwe, unikezelo lwe-MDI oluhlanganisiweyo luhlala luphezulu, isimo sengqondo semarike silumkile.Ngokugcinwa kwababoneleli kunye nokuhanjiswa okucothayo, imfuno yomyalelo igxininiswe ngakumbi, umoya wokuthenga uyafudumala, kwaye iziko lobunzima bokudibanisa intsimi ye-MDI ihambela phezulu.
Ngokumalunga nezixhobo, izixhobo ze-MDI ze-400,000 / ngonyaka ze-MDI e-Chongqing zangena kwindawo yokugcina ngoFebruwari 5, okulindeleke ukuba ihlale kude kube phakathi kuMatshi.Izixhobo ze-Ningbo ezingama-800,000/ngonyaka ziya kunqunyanyiswa ukuze zilungiswe ukusuka nge-13 kaFebruwari, ezihlala malunga neentsuku ezingama-30.Imveliso ye-MDI ehlanganisiweyo kulindeleke ukuba ibe malunga neetoni ze-152,000 ngoFebruwari, phantsi kweetoni ezingama-23,300 ukusuka kwinyanga edlulileyo.
Ngamafutshane, inkxaso yeendleko eziqinileyo ze-MDI ehlanganisiweyo, ukucutheka okulindelweyo konikezelo lwemarike, kunye nokufunyanwa kancinci kancinci kwemfuno esezantsi yomlambo, amandla amathathu adityanisiweyo anokunceda imakethi ye-MDI isuse ubuthuntu kunye nokuphuma kwinqanaba lokunyuka.
