Kuva muri Gashyantare, polymerisation yo mu gihugu ya diphenyl methane diisocyanate (MDI) yagabanijwe ku isoko Yin yagabanutse, ariko ibiciro by'ibikoresho fatizo byazamutse cyane, nko ku ya 20 Gashyantare mu karere ka Shandong aniline yazamutseho amafaranga 1000 (igiciro cya toni, kimwe hepfo).Ati: "Ibiciro byanyuma birashyigikirwa cyane no gukenera gukenera buhoro buhoro, cyangwa bizatuma isoko rusange rya MDI riva mu bihe bidahwitse, byugurure isoko."Abantu batari bake mu nganda bakoze ubushakashatsi no guca imanza.
Inkunga ikomeye
Ibikoresho bito aniline bingana na 75% yikiguzi cya MDI.Vuba aha, igiciro cya aniline kirazamuka, kandi inkunga ya MDI irashimangirwa.
Kugeza ku ya 21 Gashyantare, igiciro cy’isoko ry’amajyaruguru y’Ubushinwa aniline cyari 12.200, cyiyongereyeho amafaranga 1950 ugereranije na 28 Mutarama, cyiyongeraho 19,12%;Kuva ku ya 17 Gashyantare, hejuru ya 1200, cyangwa 10,96%.
Ati: “Ubwiyongere bukabije ku isoko rya aniline buterwa ahanini no kwiyongera kw'ibicuruzwa byo hagati no hasi.Icyifuzo cya aniline cyariyongereye, kandi n’ibice byinshi by’ibicuruzwa bizahagarikwa kugira ngo bibungabunge, icyizere cy’isoko cyongerewe imbaraga, ababikora barangirika vuba, kandi igiciro cya aniline cyazamutse cyane. ”Isesengura rya Shandong Kenli Petrochemical Group injeniyeri Wang Quanping isesengura yavuze.
Kugeza ubu, Nanhua yahagaritse toni 100.000 / umwaka igikoresho cya aniline;Chongqing BASF toni 300.000 / yumwaka gahunda yo kwishyiriraho, biteganijwe ko izamara ukwezi;Ningbo Wanhua toni 720.000 / yumwaka igikoresho cya 50%.
Uhereye kuri aniline hejuru yimbere, isoko yimbere yimbere ya benzene isoko ikomeye.Ubushinwa bwi burasirazuba bugana mubikorwa byo gutanga ibicuruzwa, kubara ibyambu byagabanutseho gato.Reta zunzubumwe zamerika isoko ryiza rya benzene ryazamutse, igiciro cyo hanze cyazamutse, igiciro cyimbere mu gihugu cya benzene yera "concave", ufite nyiricyubahiro nyuma ya saa sita.
Ati: “Mbere yuko igiciro cya aniline kitazamuka, inyungu mpuzandengo y'uruganda rwa MDI rwo mu gihugu rwa MDI yari hafi 3273.Kwiyongera kw'ibikoresho fatizo byanze bikunze bizagabanya umwanya wunguka wa polymerisiyasi MDI, bizamura ubushake bw'abakora ibiciro. ”Wang Quanping yavuze ko ku isoko rya nyuma ya saa sita, bigaragara ko itangwa rya aniline ryagabanutse, kandi ibarura rishobora kugabanuka ku rwego rwo hasi.Biteganijwe ko igiciro cya aniline kizakomeza kuzamuka mugihe gito, bigatanga inkunga kumasoko ya MDI ya polymerisme imbere yikiguzi.
Saba gusana intambwe
Nka polymeric MDI kumanuka isoko ya polyether isoko yagiye itera imbere buhoro buhoro.Gutwarwa na propylene oxyde nkibikoresho fatizo, isoko ya polyether ifungura uburyo bwo gukurura.Hafi yukwezi 1, igiciro cya polyether cyazamutse gake, hagati ya gravit, umunsi mukuru wimpeshyi wazamutseho 800.
Uhereye kubitangwa, imizigo myinshi irahagije, ariko isoko nyamukuru yo gutumiza ibicuruzwa kugirango ihagarare neza.Inganda nini zo mu majyaruguru no mu majyepfo zifite ubushake bwo gushyigikira isoko, kandi igice kinini cy’ibikorwa by’ibiti bya polyether biracyari bike na okiside ya propylene.Mubyongeyeho, abayikora bafite ibarura runaka, kandi nyuma yiminsi mikuru yimpeshyi, isoko ya okiside ya propylene iri mukuzamuka kuzamuka, kandi ibiciro byibicuruzwa byarangiye ntabwo biri hasi.Bigereranijwe ko ubushake bwoherezwa hejuru aribwo buryo nyamukuru mugihe cya vuba.
Ati: "Vuba aha, biteganijwe ko ibicuruzwa bitumizwa mu mahanga byiyongera, ariko ubwinshi bwa bubble polyether ni buke, uruganda rukomeye rwo mu gihugu rukomera ku myifatire y'umujyi."Shandong Institute of industry and information Technology abarimu bo ku rwego rwa injeniyeri mukuru Pan Jinsong yavuze.
Dufatiye ku byifuzo, gahunda yo kugurisha ibicuruzwa biva mu mahanga byinjira mu gihugu imbere birahagaze neza, kandi ikoreshwa ry’ibikoresho fatizo ku nganda zitanga umusaruro bizaba muri Werurwe.Muri Werurwe, hazerekanwa imurikagurisha ry'ibikoresho, cyangwa bizazana inyungu nziza ku isoko ry'ibikoresho fatizo.Urutonde rwohereza ibicuruzwa hanze ya sponge muri rusange.Ni ukwezi kwabanyamuryango ba Amazone muri Nyakanga.Biteganijwe ko bizagira uruhare runini mubicuruzwa byoherezwa mu mahanga -ubwoko bwa sponge nyuma ya Mata.
Urebye ibikoresho fatizo, imitako mishya yongeweho ya oxyde ya oxyde mu mpera za Gashyantare ni peteroli ya satelite gusa, kandi ibyateganijwe kubikoresho bya Ida cyangwa kongera gutangira.Ibikoresho bisigaye nta kwiyongera gukomeye kurubu.Hamwe na parikingi yicyiciro cya mbere cya Zhenhai Gutunganya no Gutunganya imiti, isoko ntiri hejuru, kandi inkunga yibiciro irarenze.Biteganijwe ko ibiciro bya oxyde propyne ikunda kuzamuka kandi bigoye kugabanuka, kandi iracyashyigikira isoko rya polyether.
Muri rusange, hari ibimenyetso byerekana iherezo ryibisabwa, bizatuma isoko rya MDI rusange rizamuka.
Biteganijwe ko kugabanuka kw'ibicuruzwa
Kugeza ubu, igabanuka ry’isoko rusange rya MDI ry’imbere mu gihugu ryaragabanutse, kandi igiciro cyatanzwe ahanini ni 15.500 ~ 15.800, naho igiciro cy’ibicuruzwa byatumijwe mu mahanga (MR200, M200) ni 15.300 ~ 15,600.
Ati: "Kugeza ubu, igiciro cyo gukusanya MDI kiracyari ku rwego rwo hasi mu myaka hafi itatu.Mu gihe cyo gushyiraho politiki nziza yo gukumira no kurwanya icyorezo cy’icyorezo no gutegereza ko ubukungu bwifashe neza, isoko rya MDI ryahujwe kuzamuka buhoro buhoro mu byiciro.Abatanga ibicuruzwa bahana umwanya mu mwanya kandi bagenda bazamura buhoro buhoro binyuze mu kugena isoko ukurikije umuvuduko w'ikoreshwa rirangiye. ”Pan Jinsong ati.
Uhereye kubitangwa, gutanga ni bike, igiteranyo cya MDI itanga gikomeza kuba kinini, imyifatire yisoko iritonda.Hamwe no kubungabunga abatanga ibicuruzwa no gutanga buhoro, gahunda yo gusaba irashimangirwa cyane, ikirere cyo kugura kirashyuha, kandi hagati yuburemere bwikusanyirizo rya MDI umurima urazamuka.
Ku bijyanye n’ibikoresho, toni 400.000 / mwaka ibikoresho bya MDI muri Chongqing byinjiye muri leta yo kubungabunga ku ya 5 Gashyantare, biteganijwe ko bizakomeza kugeza hagati muri Werurwe.Ibikoresho bya Ningbo 800.000 / umwaka bizahagarikwa kugirango bibungabunge guhera ku ya 13 Gashyantare, bizamara iminsi 30.Biteganijwe ko umusaruro rusange MDI uzaba hafi toni 152.000 muri Gashyantare, ukamanuka toni 23.300 ugereranije n’ukwezi gushize.
Muncamake, inkunga ikomeye yibiciro bya MDI rusange, biteganijwe ko igabanuka ryamasoko ryagabanutse, hamwe no gukira buhoro buhoro icyifuzo cyo hasi, izo ngabo uko ari eshatu zahujwe zishobora gufasha isoko rya MDI kwikuramo akajagari no kuva mukuzamuka.
