Ukususela ngoFebruwari, ukwenziwa kwe-polymerization yasekhaya ye-diphenyl methane diisocyanate (MDI) kwimarike kuye kwehla, kodwa amaxabiso ezinto eziluhlaza anyuka kancinci, njengoFebruwari 20 kummandla waseShandong i-aniline inyuke nge-1000 yuan (ixabiso leetoni, elifana nelingezantsi). "Ixabiso lixhasa imfuno enamandla ye-overlay downstream ukubuyiselwa kancinci kancinci, okanye kuya kuyikhupha imarike ye-MDI kwimeko yokungavisisani, ivule imarike." Inani labantu kushishino lenze uphando kunye nokugweba okungentla.
Inkxaso enamandla yeendleko
I-aniline yezinto eziluhlaza ithatha i-75% yexabiso le-MDI. Kutshanje, ixabiso le-aniline liyenyuka, kwaye inkxaso yexabiso le-MDI iye yomelezwa.
Ukuza kuthi ga nge-21 kaFebruwari, ixabiso lemarike le-aniline yaseMantla eTshayina laliyi-12,200 yuan, linyuke nge-1950 yuan xa lithelekiswa ne-28 kaJanuwari, ukunyuka kwe-19.12%; Ukususela nge-17 kaFebruwari, linyuke nge-1200 yuan, okanye i-10.96%.
“Ukunyuka okukhulu kwimarike ye-aniline kubangelwa kakhulu kukwanda kwee-odolo eziphakathi nezisezantsi. Imfuno ye-aniline inyukile, kwaye inani leeyunithi zemveliso ziya kuvalwa ukuze kugcinwe, ukuzithemba kwemarike kuyanda, abavelisi basusa ngokukhawuleza isitokhwe, kwaye ixabiso le-aniline linyuke kakhulu.” Uhlalutyo oluphezulu lweShandong Kenli Petrochemical Group uWang Quanping uthe.
Okwangoku, iNanhua iyekile isixhobo se-aniline esiziitoni ezili-100,000 ngonyaka; iChongqing BASF ipakisha iitoni ezingama-300,000 ngonyaka, kulindeleke ukuba ihlale inyanga e-1; iNingbo Wanhua i-720,000 yeetoni ngonyaka, isixhobo sisebenza ngomthwalo ongama-50%.
Ukusuka kwimbono ye-aniline ephezulu, imarike ye-benzene ecocekileyo yasekhaya yothukile kakhulu. Ukuphunyezwa okusebenzayo kwemiyalelo yokuhanjiswa kwempahla eMpuma China, uluhlu lwezinto ezithengiswayo lwehle kancinci. Imarike ye-benzene ecocekileyo yaseMelika inyukile, ixabiso langaphandle lenyuka, ixabiso lasekhaya le-benzene ecocekileyo "concave", umnini wemini ephucukileyo ngakumbi.
“Ngaphambi kokuba ixabiso le-aniline linyuke, inzuzo ephakathi yefektri ye-MDI ye-polymerization yasekhaya yayimalunga ne-3273 yuan. Ukwanda kwezinto eziluhlaza kuya kuyicinezela ngokungenakuphepheka indawo yenzuzo ye-polymerization MDI, kunyuse ukuzimisela kwabavelisi ukuhlawula amaxabiso.” UWang Quanping uthe kwimarike yasemini, ukunikezelwa kwe-aniline ngokucacileyo kuncitshisiwe, kwaye uluhlu lwezinto lunokwehla luye kwinqanaba eliphantsi. Kulindeleke ukuba ixabiso le-aniline liqhubeke nokunyuka kwixesha elifutshane, lenze inkxaso kwimarike ye-MDI eyenziwe i-polymerized xa kujongwa iindleko.
Ukulungiswa kwemfuno ngokulandelelana
Njengoko imakethi ye-polyether ye-polymeric MDI esezantsi iye yaphucuka kancinci kancinci kutshanje. Iqhutywa yi-propylene oxide njengezinto eziluhlaza, imakethi ye-polyether ivula indlela yokutsala. Phantse inyanga e-1, ixabiso le-polyether lenyuke kancinci, iziko lomxhuzulane, uMnyhadala weNtwasahlobo unyuke ngama-yuan angama-800.
Kwicala lokubonelela, umthwalo we-polyether wanele, kodwa umthombo ophambili weempahla zokungenisa ngaphakathi ukuze zihlale ziqinile. Iifektri ezinkulu emantla nasezantsi zizimisele ukuxhasa imakethi, kwaye uninzi lwendawo yokusebenza yezityalo ze-polyether isathintelwe yi-propylene oxide. Ukongeza, abavelisi banempahla ethile, kwaye emva koMnyhadala weNtwasahlobo, imakethi ye-propylene oxide ikwimeko emangalisayo yokunyuka, kwaye iindleko zeempahla ezigqityiweyo azikho phantsi. Kuqikelelwa ukuba ukuvuma okuphezulu kokuthunyelwa kwempahla yeyona nto iphambili kwixesha elizayo.
“Kutshanje, kulindeleke ukuba ukungeniswa kweempahla kwamanye amazwe kongezelele, kodwa ubungakanani be-polyether ethambileyo buncinci, umzi-mveliso oyintloko wasekhaya unamathela kwisimo sengqondo sesixeko.” Unjineli ophezulu we-Shandong Institute of industry and Information Technology uPan Jinsong uthe.
Ngokwembono yemfuno, ulungelelwaniso lwee-odolo zesiponji zorhwebo lwangaphakathi luzinzile, kwaye ukusetyenziswa okuphambili kwezinto eziluhlaza kumashishini emveliso kuya kubanjwa ngoMatshi. NgoMatshi, kuya kubanjwa umboniso wefenitshala, okanye uya kuzisa iingenelo ezilungileyo kwimarike yezinto eziluhlaza. Ulungelelwaniso lwamashishini esiponji athunyelwa ngaphandle ngokubanzi. YiNyanga yamaLungu eAmazon ngoJulayi. Kulindeleke ukuba ibe nendima ethile ekhokelayo kumashishini esiponji athunyelwa ngaphandle emva kuka-Epreli.
Ngokwembono yezinto eziluhlaza, ukuhonjiswa okutsha kwe-oxide ye-oxide ekupheleni kukaFebruwari kuxhomekeke kwi-satellite petrochemical kuphela, kwaye kulindeleke ukuba isixhobo se-Ida okanye ukuqalisa kwakhona. Izixhobo ezisele azinalo ukunyuka okukhulu kumbane. Njengoko i-packing yesigaba sokuqala se-Zhenhai Refining and Chemical iqalile, ukunikezelwa kwemarike akuphezulu, kwaye inkxaso yeendleko iphezulu. Kulindeleke ukuba amaxabiso e-oxide propyne athambekele ekunyukeni kwaye kunzima ukwehla, kwaye isaxhasa imarike ye-polyether.
Lilonke, kukho iimpawu zemfuno yokugqibela, eziya kunyusa imarike ye-MDI iyonke.
Ukuncipha okulindelekileyo kobonelelo
Okwangoku, ukwehla kwemarike ye-MDI yasekhaya kuye kwehla, kwaye ixabiso lesibonelelo liyi-15,500 ~ 15,800 yuan, kwaye ixabiso lesibonelelo seempahla ezingeniswayo (MR200, M200) yi-15,300 ~ 15,600 yuan.
“Okwangoku, ixabiso le-MDI yokuqokelelana lisekwinqanaba eliphantsi kwiminyaka ephantse ibe mithathu. Phantsi kwethemba lokuphucula imigaqo-nkqubo yokuthintela nokulawula ubhubhane kunye nokubuyela kwimeko yesiqhelo kwezoqoqosho, imakethi ye-MDI edibeneyo inyuka kancinci kancinci ngamanqanaba. Abathengisi batshintshiselana ixesha ngendawo kwaye kancinci kancinci banyuka ngokulawula imarike ngokwesantya sokusebenzisa ekupheleni kwemfuno.” utshilo uPan Jinsong.
Kwicala lokubonelela, ukubonelela kuncinci, izibonelelo ze-MDI ezihlanganisiweyo zihlala ziphezulu, isimo sengqondo semarike silumkile. Ngokugcinwa kwababoneleli kunye nokuhanjiswa okucothayo, umyalelo wemfuno ugxile ngakumbi, umoya wokuthenga uyafudumala, kwaye umbindi womxhuzulane wokudibanisa intsimi ye-MDI uyanyuka.
Ngokuphathelele izixhobo, izixhobo ze-MDI ezingama-400,000 zeetoni ngonyaka eChongqing zingene kwimeko yokugcinwa ngoFebruwari 5, ekulindeleke ukuba zihlale kude kube phakathi kuMatshi. Izixhobo ze-Ningbo ezingama-800,000 zeetoni ngonyaka ziya kumiswa ukuze zigcinwe ukususela nge-13 kaFebruwari, zihlale malunga neentsuku ezingama-30. Imveliso ye-MDI iyonke kulindeleke ukuba ibe malunga neetoni ezili-152,000 ngoFebruwari, ihle ngeetoni ezingama-23,300 kwinyanga ephelileyo.
Ngamafutshane, inkxaso enamandla yeendleko ze-aggregate MDI, ukuncipha okulindelekileyo kokunikezelwa kwemarike, kunye nokubuyela kancinci kancinci kwemfuno esezantsi, la mandla mathathu adibeneyo anokunceda imakethi ye-MDI ukuba isuse ubuthathaka kunye nokunyuka kwesantya.
