1,I-MMAamanani akhuphuke kakhulu, okuholele ekutholakaleni kwemakethe okuqinile

Kusukela ngo-2024, intengo ye-MMA (methyl methacrylate) ikhombise ukukhuphuka okukhulu. Ikakhulukazi kwikota yokuqala, ngenxa yomthelela weholide Lomkhosi Wasentwasahlobo kanye nokwehla kokukhiqizwa kwemishini ephansi komfula, intengo yemakethe yake yehla yaya ku-12200 yuan/ton. Kodwa-ke, ngokwanda kwesabelo sokuthunyelwa kwempahla kwamanye amazwe ngoNdasa, isimo sokushoda kwezimakethe zavela kancane kancane, futhi amanani alokhu enyuka kancane kancane. Abanye abakhiqizi baze bacaphuna amanani angaphezu kuka-13000 yuan/ton.

2,Imakethe ikhule ngekota yesibili, amanani afinyelela phezulu cishe eminyakeni emihlanu

Ukungena kwikota yesibili, ikakhulukazi ngemva koMkhosi we-Qingming, imakethe ye-MMA ibe nokwenyuka okukhulu. Esikhathini esingaphansi kwenyanga, intengo inyuke ngendlela efinyelela ku-3000 yuan/ton. Kusukela ngomhla zingama-24 kuMbasa, abanye abakhiqizi bacaphune i-yuan/ton eyi-16500, abangagcini nje ngokuphula irekhodi lika-2021, kodwa futhi bafinyelela endaweni ephakeme kakhulu cishe eminyakeni emihlanu.

3,Umthamo wokukhiqiza onganele ngasohlangothini lokuhlinzeka, nezimboni ezibonisa ukuzimisela okucacile ukunyusa amanani

Ngokombono wohlangothi lokunikezela, umthamo wokukhiqiza wefekthri ye-MMA usuwonke uyaqhubeka uhlala uphansi, okwamanje ungaphansi kwama-50%. Ngenxa yenzuzo engeyinhle yokukhiqiza, amabhizinisi amathathu okukhiqiza izindlela ze-C4 avaliwe kusukela ngo-2022 futhi kusamele aqalise kabusha ukukhiqiza. Emabhizinisini okukhiqiza e-ACH, amanye amadivayisi asesesimeni sokuvala shaqa. Nakuba amanye amadivaysi esephinde asebenza, ukwanda kokukhiqizwa kusephansi kunalokho obekulindelwe. Ngenxa yokucindezela okulinganiselwe kwempahla efekthri, kunesimo sengqondo esicacile sokwazisa amanani, esisekela ngokwengeziwe ukusebenza kwezinga eliphezulu kwamanani e-MMA.

4,Ukukhula kwesidingo esiphansi kuholela ekwenyukeni okukhulu kwamanani e-PMMA

Iqhutshwa ukukhuphuka okuqhubekayo kwamanani e-MMA, imikhiqizo ephansi efana ne-PMMA (polymethyl methacrylate) kanye ne-ACR nayo ibonise ukukhuphuka okucacile kwezintengo. Ikakhulukazi i-PMMA, ukuthambekela kwayo phezulu kunamandla nakakhulu. Ikhotheshini ye-PMMA eMpumalanga ye-China isifinyelele ku-18100 yuan/ton, okuwukukhuphuka ngo-1850 yuan/ton kusukela ekuqaleni kwenyanga, ngezinga lokukhula lika-11.38%. Esikhathini esifushane, ngokukhula okuqhubekayo kwesidingo esingaphansi komfula, kusenomfutho wokuthi amanani e-PMMA aqhubeke nokukhuphuka.

5,Ukusekelwa kwezindleko okuthuthukisiwe, intengo ye-acetone ifinyelela phezulu okusha

Mayelana nezindleko, njengenye yezinto ezibalulekile zokusetshenziswa kwe-MMA, intengo ye-acetone nayo ikhuphuke yaba phezulu entsha cishe unyaka. Ethintwa ukunakekelwa nokunciphisa umthwalo wemishini ye-phenolic ketone ehlobene, ukukhiqizwa kwemboni yehle kakhulu, futhi ingcindezi ekunikezeni indawo iye yancishiswa. Abanikazi banenhloso eqinile yokunyusa amanani, okuholela ekwenyukeni okuqhubekayo kwentengo yemakethe ye-acetone. Nakuba okwamanje kukhona ukuthambekela kokwehla, jikelele, intengo ephezulu ye-acetone isanikeza ukusekelwa okubalulekile kwezindleko ze-MMA.

6,Umbono wesikhathi esizayo: Izintengo ze-MMA zisenendawo yokukhuphuka

Uma kucatshangelwa izici ezifana nezindleko zempahla eluhlaza, ukukhula kwesidingo esezansi nomfula, namandla okukhiqiza ohlangothini olunganele, kulindeleke ukuthi sisekhona isikhala sokuthi amanani e-MMA anyuke. Ikakhulukazi uma kucatshangelwa ukusebenza okuphezulu kwamanani entengo ye-acetone ekhuphuka nomfula, ukukhishwa kwamayunithi amasha e-PMMA ezansi nomfula, kanye nokuqaliswa kabusha okulandelanayo kwamayunithi okulungisa kusenesikhathi we-MMA, ukushoda kwamanje kwezimpahla ezikhona kunzima ukukudambisa esikhathini esifushane. Ngakho-ke, kungabonwa kusengaphambili ukuthi izintengo ze-MMA zingase zikhuphuke.
