1,MMAamaxabiso anyuke kakhulu, nto leyo ekhokelela ekuboneleleni ngokungqongqo kwimarike

Ukusukela ngo-2024, ixabiso le-MMA (methyl methacrylate) libonise ukunyuka okubalulekileyo. Ngokukodwa kwikota yokuqala, ngenxa yempembelelo yeholide yoMnyhadala weNtwasahlobo kunye nokuncipha kwemveliso yezixhobo ezisezantsi, ixabiso lemarike liye lehla kwi-12200 yuan / ton. Nangona kunjalo, ngokunyuka kwesabelo sokuthunyelwa kwempahla kwamanye amazwe ngoMatshi, imeko yokunqongophala konikezelo lweemarike ngokuthe ngcembe yavela, kwaye amaxabiso aye anyuka ngokuthe ngcembe. Abanye abavelisi bade bacaphula amaxabiso angaphezu kwe-13000 yuan/toni.

2,Imakethi inyuke ngekota yesibini, amaxabiso afikelela kwinqanaba eliphezulu phantse kwiminyaka emihlanu

Ukungena kwikota yesibini, ngakumbi emva koMthendeleko weQingming, imarike ye-MMA yafumana ukwanda okukhulu. Ngaphantsi kwenyanga, ixabiso linyuke nge-3000 yuan/toni. Ukusukela nge-24 ka-Epreli, abanye abavelisi bacaphule i-yuan eyi-16500 / iitoni, bengaphuli nje irekhodi lika-2021, kodwa bafikelele kwelona nqanaba liphezulu phantse iminyaka emihlanu.

3,Umthamo ongonelanga wemveliso kwicala lokubonelela, kunye neefektri ezibonisa ukuzimisela okucacileyo ukunyusa amaxabiso

Ukusuka kumbono wecala lonikezelo, umthamo wemveliso we-MMA uphela uqhubeka uhlala uphantsi, okwangoku ungaphantsi kwama-50%. Ngenxa yengeniso yemveliso engekho mgangathweni, amashishini amathathu okuvelisa indlela ye-C4 aye avalwa ukususela ngo-2022 kwaye akakaphinde aqalise imveliso. Kumashishini okuvelisa i-ACH, ezinye izixhobo zisekwimeko yokuvala. Nangona ezinye izixhobo ziye zaqalisa ukusebenza, ukonyuka kwemveliso kusesezantsi kunoko bekulindelwe. Ngenxa yokunqongophala koxinzelelo lwe-inventri kumzi-mveliso, kukho isimo sengqondo esicacileyo sokuxabisa ixabiso, elixhasa ngakumbi ukusebenza kwinqanaba eliphezulu lamaxabiso e-MMA.

4,Ukukhula kweemfuno ezisezantsi kukhokelela ekunyukeni okubonakalayo kumaxabiso e-PMMA

Iqhutywe ngokunyuka okuqhubekayo kwamaxabiso e-MMA, iimveliso ezisezantsi ezifana ne-PMMA (i-polymethyl methacrylate) kunye ne-ACR nazo zibonise ukunyuka okucacileyo kumaxabiso. Ngokukodwa i-PMMA, indlela yayo yokuya phezulu inamandla ngakumbi. I-quotation ye-PMMA eMpuma ye-China ifikelele kwi-18100 yuan / ton, ukunyuka kwe-1850 yuan / ton ukususela ekuqaleni kwenyanga, kunye nesantya sokukhula kwe-11.38%. Ngexesha elifutshane, ngokukhula okuqhubekayo kwemfuno esezantsi, kusekho umfutho wamaxabiso e-PMMA ukuqhubeka nokunyuka.

5,Ukuxhaswa kweendleko eziphuculweyo, ixabiso le-acetone lifikelela phezulu

Ngokumalunga neendleko, njengenye yezinto ezibalulekileyo ze-MMA, ixabiso le-acetone liye lanyuka laya phezulu kwisithuba esingangonyaka. Ukuchaphazeleka kukugcinwa kunye nokunciphisa umthwalo wezixhobo ezinxulumene ne-phenolic ketone, imveliso yoshishino iyancipha kakhulu, kwaye uxinzelelo lokunikezelwa kwendawo luye lwancitshiswa. Abanini banenjongo eqinileyo yokunyusa amaxabiso, okukhokelela ekunyukeni okuqhubekayo kwixabiso lemarike ye-acetone. Nangona ngoku kukho ukuhla, ngokubanzi, ixabiso eliphezulu le-acetone lisabonelela ngenkxaso ebalulekileyo kwiindleko ze-MMA.

6Imbonakalo yexesha elizayo: Amaxabiso e-MMA asenayo indawo yokunyuka

Ukuthathela ingqalelo izinto ezinje ngeendleko zemathiriyeli ekrwada enyukayo, ukukhula kwemfuno esezantsi, kunye nokungonelanga komthamo wemveliso yecala, kulindeleke ukuba kusekho indawo yokuba amaxabiso e-MMA anyuke. Ingakumbi xa kuqwalaselwa ukusebenza okuphezulu kwamaxabiso e-acetone enyukayo, ukugunyaziswa kweeyunithi ezitsha ze-PMMA ezantsi, kunye nokuqaliswa kwakhona okulandelelanayo kweeyunithi zogcino lwe-MMA kwangethuba, ukunqongophala kwangoku kweempahla ze-acetone kunzima ukukuphelisa kwixesha elifutshane. Ke ngoko, kunokubonwa kwangaphambili ukuba amaxabiso e-MMA anokonyuka ngakumbi.
