Intshayelelo: Emva kokuba imarike yasekhaya esulungekileyo ye-MDI yaya kwindawo yokugcina impahla kwizinga eliphezulu ngoMeyi, indlela ehlayo ngoJuni iqhubekile nokwetyisa uluhlu lwemveliso egqityiweyo kunye noluhlu lwempahla ekrwada, iMDI esulungekileyo ngeenyanga ezimbini zokususwa kwempahla, imakethi esezantsi yodaka sele iqalile ukuthenga. iinjongo, phantsi kokuqala kwemfuno, kunokunceda i-MDI ecocekileyo iqhubele phambili phezulu?

Amaxabiso aguquguquka kuluhlu olumxinwa kwaye aqhubeke nokwetyisa uluhlu lwentlalo

Ngo-2023, ixabiso le-MDI esulungekileyo libekwe kwindawo ehambelanayo malunga neminyaka emithathu, kunye nendawo yokuguquguquka okulinganiselweyo. Nangona kunjalo, ukususela phakathi ku-Epreli, ixabiso lemarike ye-MDI ecocekileyo liye lanyuka ngokucothayo kwaye laqhubeka nokugcina ixabiso eliphezulu lonyaka, kodwa ixabiso lisekwinqanaba eliphantsi lexesha elifanayo kwiminyaka edlulileyo. Ngeli nqanaba lexabiso, icala lemfuno liqhelekileyo, ukulandelwa komyalelo kuyaqhubeka, kwaye uluhlu lweemveliso ezigqityiweyo kwinqanaba lokuqala ligaywa. Ngeli nqanaba, i-inventory yentlalontle iyaqhubeka nokwetyiswa, kwaye uluhlu olusezantsi luye lwangena kwinqanaba eliphantsi.

Ilahleko yolondolozo iphantsi ngokuqhubekayo, nto leyo ilungile kwicala lokubonelela ngemarike

I-Shanghai Lianheng 35+ 240,000 yeetoni / ngonyaka isityalo sotywala sikamama saqala ukulungiswa ngokulandelelana ukusuka kwi-11 kaJuni, echaphazela i-Shanghai Huntsman kunye ne-Shanghai BASF yokulungisa iplanti, kwaye ngaphezu kokuxhasa ukugcinwa, isigaba se-Ningbo I-400,000 yeetoni / ngonyaka ukugcinwa kwezityalo, isigaba II 800,000 iitoni/ngonyaka ukusebenza kakubi kwesityalo esisezantsi, ukongeza ekusebenzeni kakubi kwesityalo saseFujian, gcina malunga ne-50% yomthwalo okhoyo. Iyunithi ye-600,000-toni / yonyaka e-Shanghai yancitshiswa ngenxa yeengxaki zokubonelela ngezinto eziluhlaza ngaphambili. Iiseti ezininzi zokugcinwa kwesixhobo + impembelelo engalunganga, umthwalo we-MDI wasekhaya ugcinwe kuphela malunga ne-60%, kwaye ukususela ngoMatshi, umthwalo ococekileyo we-MDI uqhubekile ukwehla, kwaye izinga lokusebenza ngoJuni noJulayi ligcinwe kuphela malunga ne-60%.

Umthwalo osezantsi ukhula kancinci, kwaye ukwanda kwe-slurry kuyabonakala kakhulu

NgoMeyi, umthwalo opheleleyo wemfuno ephantsi komlambo wawuphezulu. Phakathi kwabo, umthwalo we-slurry ugcinwa malunga ne-60%, umthwalo we-liquid kuphela ugcinwa kwi-5-60%, umthwalo we-TPU ugcinwe malunga ne-70%, kwaye umthwalo we-spandex ugcinwa kwi-7-8%. Nangona kunjalo, ngamandla okusetyenziswa okulinganiselweyo kwetheminali kwi-warehouse, ukwanda kwee-odolo ze-warehouse, i-odolo yemfuno ebuthathaka phakathi kunye nasekupheleni kukaMeyi, ukungena kwinqanaba lokugaya, kunye nenzuzo esezantsi yomlambo ayilungile, i-slurry esezantsi, yodwa. ulwelo, ixabiso lentengiso yemarike yeTPU lilonke liphantsi, inzuzo encinci, ekhokelela ekunqongophelweni kokuzithemba ezantsi, umthamo ophantsi wokurhweba oqhutywa kukugcinwa komthwalo, utshintsho oluncinci kumthwalo. Kodwa imbonakalo yemarike yexesha elizayo ayikabi nethemba. Kwaye imarike ye-spandex ngenxa yoluhlu oluphezulu, imeko evulekileyo embi, imfuno iyancipha. Phakathi kwabo, umthwalo we-slurry uya kuba malunga neepesenti ze-4-5, umthwalo we-liquid kuphela uya kugcinwa kwi-5 ekhulwini, umthwalo we-TPU uya kugcinwa malunga neepesenti ze-5-6, kwaye umthwalo we-spandex uya kugcinwa malunga neepesenti ze-7. Nangona kunjalo, phakathi nasekupheleni kukaJuni, amaxabiso emarike e-slurry, i-stock sole, i-spandex kunye ne-TPU yangena kwindawo ephantsi, emva kokuba i-inventory digestion ifike kwindawo ephantsi, izinto eziluhlaza ze-BDO kunye ne-AA zaqala ngokulandelelana, intshiseko yokuthenga yanda, kwaye imarike terminal iye yanda ngenxa yenzuzo yexabiso, umdla wokuthenga ushushu, umthwalo osezantsi wonyuka ngokuthe chu, ngakumbi imfuno yemarike yoludaka ukulandela ukunyuka okucacileyo ngakumbi.

Ukuqwalasela uluhlu lwangoku oluphantsi lwentlalo, ukuxinwa kwezixhobo zokugcina, kunye nesicwangciso sexesha elide lokugcinwa kwezixhobo zaphesheya, i-Hungary's Borst Chemical Company ye-MDI isixhobo (iitoni ezingama-350,000 / ngonyaka) yaqala ukumisa imveliso ngoJulayi 18 ukwenzela ukugcinwa kunye nokuguqulwa kobugcisa kunye nokwandiswa. , kwaye yanda ukuya kwi-400,000 yeetoni / ngonyaka emva kokuguqulwa kwezobugcisa. Kulindeleke ukuba ukugcinwa kuthathe malunga neentsuku ze-80, kwaye icala lokubonelela liya kugcina ukugcinwa okuphantsi. Icala lemfuno elingaphezulu liqala ngezigaba, kwaye inqanaba lokunyusa amandla ebaleni liyatshisa, okanye lichaphazela iziko lexesha elifutshane elisulungekileyo le-MDI lomxhuzulane. Nangona kunjalo, umthamo opheleleyo wokusetyenziswa kwimarike yesiphelo awulungile, kwaye isixhobo sokugcinwa kwe-MDI ecocekileyo sigcina inxalenye yesicwangciso sokuqhuba phakathi kunye neenyanga ezisekupheleni, kwaye ivenkile yokubonelela kulindeleke ukuba inyuke kancinci okanye ichaphazele i-amplitude ye-fluctude kunye nobude bexesha. , kwaye uqhubeke nokulandela ukunyuka kweemfuno kunye nokutshintsha umthamo wokubonelela kwixesha elizayo.
