Isingeniso: Ngemuva kokuthi imakethe yasekhaya ehlanzekile ye-MDI iye endaweni yokugcina impahla ngezinga eliphezulu ngoMeyi, ukwehla kwezinga ngoJuni kwaqhubeka nokugaya uhlu lomkhiqizo oqediwe kanye nempahla eluhlaza, i-MDI emsulwa phakathi nezinyanga ezimbili zokudilizwa, imakethe ye-slurry ephansi isiqalile ukuthenga. izinhloso, ngaphansi kokuqala kwesidingo, zingasiza i-MDI emsulwa ukuthi ithuthukele phezulu?

Amanani ayashintshashintsha ebangeni elincane futhi ayaqhubeka nokugaya izinto zomphakathi

Ngo-2023, intengo ye-MDI emsulwa itholakala endaweni yokuma ehlobene cishe iminyaka emithathu, nesikhala sokuguquguquka esilinganiselwe. Kodwa-ke, kusukela maphakathi no-Ephreli, intengo yemakethe ye-MDI ehlanzekile ikhuphuke kancane futhi yaqhubeka nokugcina intengo ephakeme kakhulu yonyaka, kodwa intengo isesezingeni eliphansi lenkathi efanayo eminyakeni edlule. Kulesi sigaba samanani, uhlangothi lwesidingo lujwayelekile, ukulandelwa kwe-oda kuyaqhubeka, futhi uhlu lwemikhiqizo eqediwe esigabeni sokuqala luyagaywa. Kulesi sigaba, i-inventory yezenhlalakahle iyaqhubeka nokugaya, futhi i-inventory engezansi nayo ingene ezingeni eliphansi.

Ukulahlekelwa kwesondlo kuhlezi kuphansi, okuhle ngasohlangothini lokuhlinzekwa kwemakethe

I-Shanghai Lianheng 35+ 240,000 amathani/imboni yotshwala kamama yaqala ukulungiswa ngokulandelana kusukela ngoJuni 11, yathinta imboni yokulungisa i-Shanghai Huntsman kanye ne-Shanghai BASF, futhi ngaphezu kokusekela ukulungiswa, i-Ningbo phase I 400,000 amathani/ngonyaka wokulungisa ukuvalwa kwezitshalo, isigaba II 800,000 amathani/ngonyaka ukusebenza okungalungile kwesitshalo okuphansi, ngaphezu kokusebenza kabi kwesitshalo se-Fujian, gcina cishe u-50% wokulayishwayo. Iyunithi engu-600,000-ton/ngonyaka e-Shanghai yehlisiwe ngenxa yezinkinga zokuhlinzekwa kwempahla eluhlaza yangaphambili. Amasethi amaningi okugcinwa kwedivayisi + nomthelela omubi, ukulayishwa kwe-MDI yasekhaya sekukonke kugcine cishe u-60% kuphela, futhi kusukela ngoMashi, umthwalo omsulwa we-MDI uqhubekile ukwehla, futhi izinga lokusebenza ngoJuni nangoJulayi ligcine cishe u-60%.

Umthwalo ongezansi ukhula kancane, futhi ukwanda kwe-slurry kubonakala kakhulu

NgoMeyi, inani eliphelele lesidingo esingaphansi komfula laliphezulu. Phakathi kwazo, umthwalo we-slurry ugcinwa cishe ku-60%, umthwalo we-liquid kuphela ugcinwa ku-5-60%, umthwalo we-TPU ugcinwa cishe ngo-70%, futhi umthwalo we-spandex ugcinwa ku-7-8%. Kodwa-ke, ngamandla okusebenzisa alinganiselwe wetheminali endaweni yokugcina impahla, ukwanda kwama-oda we-warehouse, ama-oda wesidingo esibuthakathaka phakathi nasekupheleni kukaMeyi, angena esigabeni sokugaya ukudla, kanye nenzuzo yonke engaphansi komfula ayilungile, i-slurry ephansi, i-sole. uketshezi, intengo yemakethe ye-TPU iyonke yokuhweba iphansi, inzuzo encane, okuholela ekuntulekeni kokuzethemba komfula, umthamo ophansi wokuhweba oqhutshwa ukugcinwa komthwalo, ushintsho oluncane emthwalweni. Kodwa umbono wemakethe yesikhathi esizayo awukabi nathemba. Futhi imakethe ye-spandex ngenxa yokusungula okuphezulu, isimo esibi esivulekile, isidingo sehlile. Phakathi kwabo, umthwalo we-slurry uzoba ngamaphesenti angu-4-5, umthwalo we-liquid kuphela uzogcinwa ngamaphesenti angu-5, umthwalo we-TPU uzogcinwa cishe ngamaphesenti angu-5-6, futhi umthwalo we-spandex uzogcinwa cishe ngamaphesenti angu-7. Kodwa-ke, maphakathi nasekupheleni kukaJuni, amanani emakethe e-slurry, i-sole stock, i-spandex ne-TPU angena endaweni ephansi, ngemuva kokugayeka kwempahla kuze kufike endaweni ephansi, izinto zokusetshenziswa ze-BDO ne-AA zaqala ngokulandelana, umdlandla wokuthenga wanda, futhi imakethe yetheminali inyukile ngenxa yenzuzo yentengo, umdlandla wokuthenga washuba, umthwalo ophansi nomfula wanda kancane, ikakhulukazi isidingo semakethe enodaka ukuze kulandele ukukhula okusobala kakhulu.

Uma kucatshangelwa uhlu lwamanje oluphansi lwenhlalo, ukuqoqwa kwemishini yokulungisa, kanye nohlelo lwesikhathi eside lokunakekelwa kwemishini yaphesheya, idivayisi ye-MDI ye-Borst Chemical Company yaseHungary (amathani angu-350,000/ngonyaka) yaqala ukumisa ukukhiqizwa ngoJulayi 18 ukuze kulungiswe nokuguqulwa kwezobuchwepheshe kanye nokunwetshwa. , futhi senyuke safinyelela kumathani angu-400,000/ngonyaka ngemva koshintsho lobuchwepheshe. Kulindeleke ukuthi ukulungiswa kuzothatha izinsuku ezingaba ngu-80, kanti uhlangothi lokuhlinzeka luzogcina isitoreji esiphansi. Uhlangothi lwesidingo oluphezulu luqala ngezigaba, futhi amandla esiteji akhulisa amandla ensimini ayashisa, noma athinte isikhungo sesikhathi esifushane esihlanzekile se-MDI sokudonsela phansi. Kodwa-ke, inani eliphelele lokusebenzisa imakethe yetheminali alilungile, futhi idivayisi ehlanzekile ye-MDI yokulungisa igcina ingxenye yohlelo lokushayela phakathi nezinyanga ezimaphakathi nezakamuva, kanti isitolo sokuhlinzeka kulindeleke ukuthi sikhuphuke kancane noma sithinte i-amplitude yokuguquguquka nobude besikhathi. , futhi uqhubeke ulandelela ukwanda kwesidingo kanye noshintsho lwevolumu yokuhlinzeka esikhathini esizayo.
