Kubva muna Kukadzi, polymerization yemusika we diphenyl methane diisocyanate (MDI) yakaderedzwa zvakanyanya, asi mitengo yezvinhu zvakabikwa yakawedzera zvishoma nezvishoma, senge musi waKukadzi 20 munharaunda yeShandong aniline yakakwira ne1000 yuan (mutengo wetani, wakafanana pazasi). "Kukosha kunotsigira kudiwa kwakasimba kwe overlay downstream kudzoreredzwa zvishoma nezvishoma, kana kuti kuchadzinga musika we aggregate MDI kubva mumamiriro ezvinhu asina kumira zvakanaka, kuvhura musika." Vanhu vakati wandei muindasitiri iyi vakaita tsvakiridzo nekutonga pamusoro apa.
Rutsigiro rwakasimba rwemutengo
Aniline yezvinhu zvisina kugadzirwa ndiyo inobhadhara 75% yemari yeMDI. Munguva pfupi yapfuura, mutengo weaniline uri kukwira, uye rutsigiro rwemari yeMDI rwakawedzerwa.
Kusvika Kukadzi 21, mutengo wemusika weNorth China aniline waive 12,200 yuan, wakawedzera ne1950 yuan zvichienzaniswa naNdira 28, kuwedzera kwe19.12%; Kubva Kukadzi 17, wakawedzera ne1200 yuan, kana 10.96%.
"Kukwira kwakanyanya mumusika weaniline kunonyanya kukonzerwa nekuwedzera kwemitengo yepakati neyepasi. Kudiwa kweaniline kwakawedzera, uye huwandu hwemayuniti ekugadzira achavharwa kuti agadziriswe, chivimbo chemusika chakawedzerwa, vagadziri vanokurumidza kubvisa zvinhu, uye mutengo weaniline wakakwira zvakanyanya." Shandong Kenli Petrochemical Group mukuru weinjiniya Wang Quanping akaongorora akadaro.
Parizvino, Nanhua yakamisa kushandiswa kwemudziyo weaniline unorema matani 100,000 pagore; Chongqing BASF ine matani 300,000 pagore, inotarisirwa kushanda kwemwedzi mumwe chete; Ningbo Wanhua ine matani 720,000 pagore, uye mutoro wayo unorema 50%.
Kubva pakuona kwe aniline kumusoro kwerwizi, musika we pure benzene wemuno wakakatyamadzwa zvikuru. Kuitwa kwemirairo yekutumira zvinhu kuEast China pasi perwizi kwakadzikira zvishoma. Musika we pure benzene weUnited States wakakwira, mutengo wekunze wakakwira, mutengo we pure benzene "concave" wemuno, muridzi we the more bullish afternoon.
"Mutengo weaniline usati wakwira, avhareji yepurofiti yefekitori yeMDI yepolymerization yemuno yaive inenge 3273 yuan. Kuwedzera kwezvinhu zvakagadzirwa kuchaderedza mukana wepurofiti yeMDI yepolymerization, zvichiwedzera kuda kwevagadziri kutenga." Wang Quanping akati mumusika wemasikati, kuwanikwa kweaniline kwadzikira zviri pachena, uye zvinhu zvinogona kudzikira kusvika padanho rakaderera. Zvinotarisirwa kuti mutengo weaniline ucharamba uchikwira munguva pfupi, zvichigadzira rutsigiro kumusika weMDI wepolymerized pasinei nemutengo.
Kugadziriswa kwezvinodiwa zvishoma nezvishoma
Sezvo musika wepolyether uri pasi peMDI polymeric wave nani zvishoma nezvishoma munguva pfupi yapfuura. Uchitungamirirwa nepropylene oxide sechinhu chisina kugadzirwa, musika wepolyether unovhura nzira yekudhonza. Kwapera mwedzi mumwe chete, mutengo wepolyether wakakwira zvishoma, pakati pesimba remagetsi, Mutambo weChirimo wakakwira ne800 yuan.
Kubva kudivi rekupa, zvinhu zvinotakura polyether zvakakwana, asi nzvimbo huru yekupinza zvinhu kuti zvirambe zvakamanikana. Mafekitori makuru kuchamhembe nekumaodzanyemba anoda kutsigira musika, uye nzvimbo zhinji dzekushanda dzemafekitori epolyether dzichiri kuganhurirwa nepropylene oxide. Pamusoro pezvo, vagadziri vane zvinhu zvakati wandei, uye mushure meMutambo weChirimo, musika wepropylene oxide uri kukwira zvinoshamisa, uye mutengo wezvinhu zvakagadzirwa hausi wakaderera. Zvinofungidzirwa kuti kuda kutumira zvinhu zvakawanda ndiko kuri kukuru munguva pfupi iri kutevera.
"Munguva pfupi yapfuura, zvinhu zvinotengwa kunze kwenyika zvinotarisirwa kuwedzera, asi huwandu hwepolyether yakapfava yebubble hwakaderera, fekitari huru yemuno inotevedzera mafungiro eguta." Mainjiniya weShandong Institute of industry and information Technology, Pan Jinsong, akadaro.
Kubva pamaonero ekudiwa, kurongeka kwemirairo yekushambadzira kwemukati menyika kwakadzikama, uye kushandiswa kukuru kwezvinhu zvakagadzirwa kumabhizinesi ekugadzira kuchaitwa munaKurume. MunaKurume, kuratidzwa kwefenicha kuchaitwa, kana kuti kuchaunza mabhenefiti akanaka kumusika wezvinhu zvakagadzirwa. Kurongeka kwemakambani ekutengesa kunze kwenyika kazhinji kunoitika. Imwedzi weNhengo yeAmazon munaChikunguru. Zvinotarisirwa kuti ichave nebasa guru mumakambani ekutengesa kunze kwenyika mushure meKubvumbi.
Kubva pamaonero ezvinhu zvakagadzirwa, kushongedzwa kuchangobva kuwedzerwa kweoxide yeoxide pakupera kwaKukadzi kunongova satellite petrochemical, uye zvinotarisirwa zveIda device kana kutangazve kwemagetsi. Midziyo yasara haina kuwedzera kwakakosha mumagetsi. Nekupaka mota kwechikamu chekutanga cheZhenhai Refining neChemical, kuwanikwa kwemagetsi pamusika hakuna kukwira, uye rutsigiro rwemari rwakawedzerwa. Zvinotarisirwa kuti mitengo ye oxide propyne inogona kukwira uye kuoma kudzikira, uye ichiri kutsigira musika we polyether.
Pakazara, pane zviratidzo zvekuti kudiwa kwemari kwapera, izvo zvichaita kuti musika weMDI usimukire.
Kuderedzwa kwezviwanikwa kunotarisirwa
Parizvino, kudzikira kwemusika weMDI wemuno kwaderera, uye mutengo wezvipo unonyanya kuva 15,500 ~ 15,800 yuan, uye mutengo wezvipo wezvinhu zvinotengeswa kunze kwenyika (MR200, M200) uri 15,300 ~ 15,600 yuan.
"Parizvino, mutengo wekuunganidza MDI uchiri padanho rakaderera mumakore anoda kusvika matatu. Nekuda kwekuvandudzwa kwemitemo yekudzivirira nekudzora denda uye hupfumi huri kumirira kupora, musika weMDI wakabatana unokwira zvishoma nezvishoma muzvikamu. Vatengesi vanochinjana nguva nenzvimbo uye vanosimudzira zvishoma nezvishoma kuburikidza nemitemo yemusika zvichienderana nekumhanya kwekushandiswa pakupera kwekudiwa," akadaro Pan Jinsong.
Kubva kudivi rekupa, kuwanikwa kwezvigadzirwa kwakaderera, zvinopihwa neMDI zvakazara zvichiri kukwira, mafungiro emusika ndeekungwarira. Nekuchengetedzwa kwevatengesi uye kutumirwa kwavo kunononoka, kudiwa kwezvinodiwa kwakawedzera, mamiriro ekutenga ari kuwedzera, uye pakati pesimba rekuunganidza zvinhu zveMDI zviri kukwira.
Panyaya yemichina, michina yeMDI inosvika matani 400,000 pagore muChongqing yakapinda muchirongwa chekugadzirisa musi wa5 Kukadzi, icho chinotarisirwa kugara kusvika pakati paKurume. Michina yeNingbo inosvika matani 800,000 pagore ichamiswa kugadziriswa kubva musi wa13 Kukadzi, ichigara kwemazuva angangoita 30. Kugadzirwa kweMDI yose kunotarisirwa kuva matani angangoita 152,000 muna Kukadzi, kuderera nematani 23,300 kubva mumwedzi wapfuura.
Muchidimbu, rutsigiro rwakasimba rwemutengo weMDI, kudzikira kwemutengo wemusika, uye kudzoreredzwa zvishoma nezvishoma kwezvinodiwa, masimba matatu aya akabatanidzwa anogona kubatsira musika weMDI kubvisa kufinha uye kubva mukufambira mberi kwemusika.
