Kusukela ngoFebhuwari, i-polymerization yasekhaya ye-diphenyl methane diisocyanate (MDI) yemakethe ebanjwa yi-Yin phansi, kodwa amanani wezinto ezibonakalayo akhuphuka kancane kancane, njengoFebhuwari 20 esifundeni saseShandong i-aniline yaphakama i-yuan engu-1000 (intengo yethani, efanayo ngezansi)."Izindleko zisekela ukunqwabelana okuqinile kwesidingo sokululama kancane kancane, noma kuzokhipha imakethe ye-MDI esimeni esishubile, kuvule imakethe."Idlanzana labantu embonini lenze ucwaningo nokwahlulela okungenhla.
Ukusekelwa kwezindleko okuqinile
I-aniline yezinto ezingavuthiwe ibiza u-75% wezindleko ze-MDI.Muva nje, intengo ye-aniline iyenyuka, futhi ukusekelwa kwezindleko ze-MDI kuyaqiniswa.
Kuze kube ngumhla zingama-21 kuNhlolanja, intengo yemakethe ye-aniline yaseNyakatho yeChina yayingamayuan ayi-12,200, inyuke ngo-1950 yuan uma iqhathaniswa noJanuwari 28, inyuke ngo-19.12%;Kusukela ngo-February 17, phezulu 1200 yuan, noma 10.96%.
“Ukwenyuka okukhulu kwemakethe yezilwane ezifuywayo kudalwa ikakhulukazi ukwanda kwama-oda aphakathi nendawo naphansi.Isidingo se-aniline sinyukile, futhi inqwaba yamayunithi okukhiqiza izovalwa ukuze ilungiswe, ukuzethemba kwemakethe kukhule, abakhiqizi bancipha ngokushesha, futhi intengo ye-aniline yenyuka kakhulu.”Unjiniyela omkhulu weShandong Kenli Petrochemical Group u-Wang Quanping uthe.
Njengamanje, iNanhua imise amathani ayi-100,000/ngonyaka idivayisi ye-aniline;I-Chongqing BASF amathani angu-300,000/ngonyaka wokupaka, okulindeleke ukuthi ihlale inyanga engu-1;Ningbo Wanhua amathani 720,000/ngonyaka idivayisi 50% umsebenzi wokulayisha.
Uma ubheka phezulu nomfula i-aniline, imakethe yasekhaya ye-benzene ehlanzekile ishaqekile.Ukuqaliswa okusebenzayo kwe-East China komfula okusebenzayo kwama-oda okulethwa, ukusungula kwechweba kwehle kancane.Imakethe ye-benzene yase-United States yenyuka, intengo yangaphandle yenyukile, intengo yasekhaya ye-benzene ehlanzekile “i-concave”, ephethe intambama eyengeziwe.
“Ngaphambi kokuthi intengo ye-aniline ingakhuphuki, isilinganiso senzuzo yefekthri ye-MDI ye-polymerization yasekhaya yayilinganiselwa ku-3273 yuan.Ukwanda kwezinto ezingavuthiwe kuzocindezela nakanjani indawo yenzuzo ye-polymerization MDI, kuthuthukise ukuzimisela kwabakhiqizi emananini. "U-Wang Quanping uthe emakethe yantambama, ukunikezwa kwe-aniline kuyancipha ngokusobala, futhi i-inventory ingase yehlele ezingeni eliphansi.Kulindeleke ukuthi intengo ye-aniline iqhubeke nokukhuphuka esikhathini esifushane, yakha ukusekelwa kwemakethe ye-MDI eyenziwe nge-polymerized phambi kwezindleko.
Funa ukulungiswa okuhamba kancane
Njenge-polymeric MDI imakethe ye-polyether eyehlayo iye yaba ngcono kancane kancane muva nje.Iqhutshwa yi-propylene oxide njengento eluhlaza, imakethe ye-polyether ivula imodi yokudonsa.Cishe inyanga engu-1, intengo ye-polyether yenyuka kancane, isikhungo samandla adonsela phansi, uMkhosi waseNtwasahlobo ukhuphuke ngamayuan angama-800.
Kusukela ohlangothini lokunikezela, i-polyether cargo yanele, kodwa umthombo oyinhloko wokungenisa wezimpahla ukugcina isimo esiqinile.Izimboni ezinkulu enyakatho naseningizimu zizimisele ukusekela imakethe, futhi iningi lendawo yokusebenza yezitshalo ze-polyether zisanqunyelwe i-propylene oxide.Ngaphezu kwalokho, abakhiqizi bane-inventory ethile, futhi ngemva koMkhosi Wasentwasahlobo, imakethe ye-propylene oxide isesimweni sokushaqeka, futhi izindleko zokusungula zemikhiqizo eqediwe azikho ngaphansi.Kulinganiselwa ukuthi ukuzimisela kokuthunyelwa okuphezulu yikhona okujwayelekile esikhathini esizayo esiseduze.
"Muva nje, kulindeleke ukuthi kungezwe izimpahla kwamanye amazwe, kodwa inani le-bubble polyether ethambile lincane, imboni enkulu yasekhaya inamathela esimweni sedolobha."Unjiniyela omkhulu weShandong Institute of industry and information Technology uPan Jinsong uthe.
Ngokombono wesidingo, ukuhleleka kwe-oda lesiponji sohwebo lwangaphakathi eliphansi komfula lizinzile, futhi ukusetshenziswa okuyinhloko kwezinto ezingavuthiwe zamabhizinisi okukhiqiza kuzobanjwa ngoMashi.NgoMashi, kuzoba nombukiso wefenisha, noma uzoletha izinzuzo ezinhle emakethe yempahla eluhlaza.Ukuhleleka kwamabhizinisi esipontshi okuthekelisa ngokujwayelekile.Yinyanga Yamalungu e-Amazon ngoJulayi.Kulindeleke ukuthi ibe neqhaza elithile eliholayo emabhizinisini ezipontshi athumela ngaphandle ngemva kuka-April.
Ngokombono wezinto ezingavuthiwe, umhlobiso osanda kungezwa we-oxide ye-oxide ngasekupheleni kukaFebruwari i-petrochemical yesathelayithi kuphela, kanye nokulindelwe okulindelekile kwedivayisi ye-Ida noma ukuqaliswa kabusha kokuqalwa kabusha.Amadivayisi asele awanakho ukukhuphuka okuphawulekayo kwamanje.Ngokupaka kwesigaba sokuqala se-Zhenhai Refining and Chemical, ukunikezwa kwemakethe akuphezulu, futhi ukusekelwa kwezindleko kuphakeme.Kulindeleke ukuthi amanani entengo ye-oxide propyne athambekele ekukhuphukeni futhi kunzima ukwehla, futhi isasekela imakethe ye-polyether.
Sekukonke, kunezimpawu zesidingo sokuphela, esizoqhuba imakethe ye-MDI ehlanganisiwe ukuthi ikhuphuke.
Ukuncipha kokunikezwayo okulindelekile
Njengamanje, ukwehla kwemakethe ye-MDI ehlanganisiwe yasekhaya kwehlile, futhi intengo yokunikezwayo ngokuvamile ingama-yuan angu-15,500 ~ 15,800, futhi intengo yokunikezwayo yempahla engenisiwe (MR200, M200) ingu-15,300 ~ 15,600 yuan.
"Okwamanje, intengo ye-MDI yokuhlanganisa isesezingeni eliphansi cishe eminyakeni emithathu. Ngaphansi kwethemba lezinqubomgomo zokuvimbela nokulawula ubhubhane kanye nokulinda ukusimama komnotho, imakethe ye-MDI ehlanganisiwe ikhuphuka kancane kancane ngezigaba.Abahlinzeki bashintsha isikhathi ukuze bathole indawo futhi kancane kancane baqhubekele phambili ngokulawula imakethe ngokuya ngejubane lokusetshenziswa ekupheleni kwesidingo. "Kusho uPan Jinsong.
Kusukela ohlangothini lokunikezela, ukunikezwa kunqunyelwe, ukunikezwa kwe-MDI okuhlanganisiwe kuhlala kuphezulu, isimo semakethe siyaqaphela.Ngokunakekelwa kwabahlinzeki kanye nokulethwa okuhamba kancane, i-oda lokufunwa ligxile kakhulu, isimo sokuthenga siyashisa, futhi isikhungo sobunzima bensimu ye-MDI yokuhlanganisa siyakhuphuka.
Mayelana nemishini, amathani angu-400,000/ngonyaka wemishini ye-MDI e-Chongqing yangena endaweni yokulungiswa ngoFebhuwari 5, okulindeleke ukuthi ihlale kuze kube maphakathi no-March.Imishini ye-Ningbo engamathani angu-800,000/ngonyaka izomiswa ukuze ilungiswe kusukela ngo-February 13, ehlala cishe izinsuku ezingu-30.Ukukhiqizwa kwe-MDI okuhlanganisiwe kulindeleke ukuthi kube amathani ayi-152,000 ngoFebhuwari, kwehle ngamathani angama-23,300 ukusuka enyangeni edlule.
Kafushane, ukusekelwa okuqinile kwezindleko ze-MDI ehlanganisiwe, ukuncipha okulindelekile kokuhlinzekwa kwemakethe, kanye nokululama kancane kancane kwesidingo esiphansi somfula, amandla amathathu ahlangene angasiza imakethe ye-MDI ukuqeda okubuthuntu kanye nokuphuma kwegagasi lokukhuphuka.
