Intshayelelo: Emva kokuba imakethi ye-MDI ecocekileyo yasekhaya iye kwindawo yokugcina impahla kwinqanaba eliphezulu ngoMeyi, ukuhla kwexabiso ngoJuni kwaqhubeka nokugaya uluhlu lwemveliso egqityiweyo kunye noluhlu lwezinto eziluhlaza, i-MDI ecocekileyo kwiinyanga ezimbini zokususa isitokhwe, imakethi ye-slurry esezantsi iqalile ukuthenga iinjongo, phantsi kokuqala kwemfuno, inokunceda i-MDI ecocekileyo ukuba inyuke?

Amaxabiso ayatshintshatshintsha kuluhlu oluncinci kwaye ayaqhubeka nokugaya izinto ezikwi-intanethi

Ngowama-2023, ixabiso le-MDI ecocekileyo likwindawo emalunga neminyaka emithathu, kunye nendawo encinci yokuguquguquka iyonke. Nangona kunjalo, ukusukela phakathi ku-Epreli, ixabiso lemarike le-MDI ecocekileyo linyuke kancinci kwaye laqhubeka nokugcina ixabiso eliphezulu lonyaka, kodwa ixabiso lisekwinqanaba eliphantsi lexesha elifanayo kwiminyaka edlulileyo. Kweli nqanaba lexabiso, icala lemfuno libanzi, ukulandelwa kwe-odolo kuyaqhubeka, kwaye uluhlu lweemveliso ezigqityiweyo kwinqanaba lokuqala luyacutshungulwa. Kweli nqanaba, uluhlu lwempahla yoluntu luyaqhubeka nocutshungulwa, kwaye uluhlu lwempahla olusezantsi nalo lungene kwinqanaba eliphantsi.

Ilahleko yolondolozo iphantsi rhoqo, nto leyo ilungele ukubonelela ngemarike

I-Shanghai Lianheng, isikhululo sotywala esingaphezu kwama-35,000 eetoni ngonyaka, saqala ukulungiswa ngokulandelelana ukususela nge-11 kaJuni, nto leyo echaphazela isikhululo sokulungisa i-Shanghai Huntsman kunye ne-Shanghai BASF, kwaye ukongeza ekuxhaseni ukugcinwa, ukugcinwa kwe-Ningbo phase I iitoni ezingama-400,000 ngonyaka, ukugcinwa kwe-phase II iitoni ezingama-800,000 ngonyaka, ukusebenza kwe-phase II kweetoni ezingama-800,000 ngonyaka, ukongeza ekusebenzeni kwe-Fujian negative, kugcina malunga ne-50% yomthwalo okhoyo. Iyunithi ye-600,000 yeetoni ngonyaka eShanghai yehlisiwe ngenxa yeengxaki zokubonelela ngezinto eziluhlaza. Iiseti ezininzi zokugcinwa kwezixhobo + impembelelo embi, umthwalo we-MDI wasekhaya ugcinwe malunga ne-60% kuphela, kwaye ukusukela ngoMatshi, umthwalo we-MDI ococekileyo uqhubeka nokwehla, kwaye izinga lokusebenza ngoJuni nangoJulayi ligcinwe malunga ne-60%.

Umthwalo osezantsi uyanda kancinci, kwaye ukwanda koludaka yeyona nto ibonakalayo

NgoMeyi, umthwalo uwonke wemfuno esezantsi wawuphezulu. Phakathi kwazo, umthwalo we-slurry ugcinwa malunga ne-60%, umthwalo we-sole liquid ugcinwa kwi-5-60%, umthwalo we-TPU ugcinwa malunga ne-70%, kwaye umthwalo we-spandex ugcinwa kwi-7-8%. Nangona kunjalo, ngamandla okusetyenziswa okuncinci kwe-terminal ukuya kwindawo yokugcina impahla, ukwanda kwee-odolo ze-warehouse, ii-odolo zemfuno ezibuthathaka phakathi nasekupheleni kukaMeyi, zingena kwinqanaba lokugaya, kwaye inzuzo iyonke esezantsi ayilunganga, i-slurry esezantsi, i-sole liquid, ixabiso lokurhweba lemarike ye-TPU liphantsi, inzuzo encinci, okubangela ukungabikho kokuzithemba ezantsi, umthamo ophantsi wokurhweba oqhutywa kukugcinwa komthwalo, utshintsho oluncinci kumthwalo. Kodwa imbono yemarike yexesha elizayo ayikabi nethemba kangako. Kwaye imarike ye-spandex ngenxa yempahla ephezulu, imeko evulekileyo embi, imfuno inciphile. Phakathi kwazo, umthwalo we-slurry uza kuba malunga ne-4-5 ekhulwini, umthwalo we-sole liquid uza kugcinwa kwi-5 ekhulwini, umthwalo we-TPU uza kugcinwa malunga ne-5-6 ekhulwini, kwaye umthwalo we-spandex uza kugcinwa malunga ne-7 ekhulwini. Nangona kunjalo, phakathi nasekupheleni kukaJuni, amaxabiso emarike e-slurry, i-sole stock, i-spandex kunye ne-TPU angene kwinqanaba eliphantsi, emva kokugaywa kwempahla ukuya kwinqanaba eliphantsi, izinto eziluhlaza i-BDO kunye ne-AA zaqala ngokulandelelana, umdla wokuthenga wanda, kwaye imakethi yesiphelo yanda ngenxa yenzuzo yexabiso, umdla wokuthenga wanda, umthwalo osezantsi wanda kancinci, ingakumbi imfuno yemarike ye-slurry yokulandela ukwanda okucacileyo ngakumbi.

Ukuqwalasela uluhlu oluphantsi lwezixhobo zoluntu ezikhoyo ngoku, uxinano lwezixhobo zolondolozo, kunye nesicwangciso solondolozo sexesha elide sezixhobo zaphesheya, isixhobo seBorst Chemical Company MDI saseHungary (iitoni ezingama-350,000 ngonyaka) saqala ukuyeka imveliso ngoJulayi 18 ngenxa yolondolozo kunye notshintsho lobuchwephesha kunye nokwandiswa, saza sanda saya kwiitoni ezingama-400,000 ngonyaka emva kotshintsho lobuchwephesha. Kulindeleke ukuba ulondolozo luthathe malunga neentsuku ezingama-80, kwaye icala lokubonelela liya kugcina indawo yokugcina iphantsi. Icala lemfuno elibekwe ngaphezulu liqala ngamanqanaba, kwaye amandla okunyusa inqanaba ebaleni ayatshisa, okanye achaphazele iziko le-MDI elicocekileyo lexesha elifutshane. Nangona kunjalo, amandla okusetyenziswa ngokubanzi kwimarike yesiphelo alungile, kwaye isixhobo solondolozo se-MDI esicocekileyo sigcina inxalenye yesicwangciso sokuqhuba kwiinyanga eziphakathi nezisekupheleni, kwaye ivenkile yokubonelela kulindeleke ukuba inyuke kancinci okanye ichaphazele ubukhulu bokuguquguquka kunye nobude bexesha, kwaye iqhubeke nokulandela ukunyuka kwemfuno kunye notshintsho lomthamo wokubonelela kwixesha elizayo.
