Ukuqaphela Okujulile Ngochungechunge Lwezimboni Lwe-Acetic Acid Yomhlaba Wonke: Ukukhiqiza Okuphansi Kusekela Isidingo, Ukungqubuzana Kwezohwebo kanye Nezingcindezi Zezindleko Kuyaqhubeka

I-Acetic acid iyi-organic acid ebaluleke kakhulu emhlabeni, esetshenziswa kabanzi ku-PTA, i-vinyl acetate, izembozo nama-ink, ukuphrinta nokudaya izindwangu, izilondolozi zokudla kanye nokuhlanganiswa kwemithi. Uchungechunge lwayo lwezimboni luxhumene kakhulu ne-methanol ne-ethanol. I-Methanol carbonylation imelela ubuchwepheshe bokukhiqiza obuvelele, obucishe bube ngu-90% womthamo womhlaba wonke. Ukuguquguquka kwentengo ye-Methanol kudlulisela ngqo emananini e-acetic acid, okuphawula lo mkhakha ngezici eziqinile zomjikelezo. Ekusetshenzisweni kwe-acetic acid emhlabeni jikelele, i-Asia Pacific ibala u-34.6% womthamo ophelele. Izimboni zokukhiqiza eShayina, eNingizimu Korea naseNingizimu-mpumalanga ye-Asia zakha izisekelo eziyinhloko zokusetshenziswa, lapho ukuchuma kwemakethe kunqunywa yizembozo, imikhakha ye-polymer kanye neyendwangu.

Ngasohlangothini lokuhlinzekwa, umthamo we-acetic acid womhlaba wonke ugxile eMpumalanga Asia naseNyakatho Melika. Ukwengezwa kwamandla amasha ase-Asia eminyakeni yamuva nje kunikeza ukuhlinzekwa okwanele komhlaba wonke, kodwa ukuphazamiseka kwe-methanol yezinto zokusetshenziswa kubangele ukuguquguquka kwezinga lokusebenza ngezikhathi ezithile. Ukuhlinzekwa kwe-methanol eMiddle East ngo-2026 kwaphakamisa izindleko ze-methanol phesheya kwezilwandle, kwanyusa izingcaphuno ze-acetic acid phesheya kwezilwandle eYurophu naseMelika. Umthamo owanele wase-Asia wendawo udala izikhala zamanani ezisobala zesifunda. Amafasitela e-arbitrage awela esifundeni avame ukuvulwa, okwenza imithwalo emikhulu yempahla evela e-Asia ithunyelwe kwamanye amazwe.

Imikhakha emincane engezansi ikhombisa ukusebenza okuhlukile. Isidingo se-vinyl acetate EVA resin sihlala siqinile; izidingo zefilimu yokufaka i-photovoltaic zikhulisa ukusetshenziswa kwe-EVA futhi ziphakamisa ngokungaqondile ukusetshenziswa kwe-acetic acid. Izembozo, uyinki kanye nemikhakha yokudaya izindwangu ziyashintshashintsha ngemva kwemijikelezo yomkhakha wokukhiqiza. I-acetic acid yezinga lokudla yokunambitheka nokulondolozwa kokudla igcina ukukhula okuzinzile. I-acetic acid derivatives efana ne-ethyl acetate ibhalisela amanani asebenzayo okuthumela kwamanye amazwe, kodwa izingozi zokungqubuzana kwezohwebo lwamazwe ngamazwe ziyanda. Ngo-Agasti 2026, iKhomishini Yezohwebo yaseKorea yethule uphenyo lokulwa nokulahla imfucuza oluqondise i-ethyl acetate evela eShayina. Lokhu kuzoshintsha okwesikhashana ukuhamba kokuhweba kwesifunda, kanye nemithwalo engaphelele ebuyela ezimakethe zasekhaya futhi kushintshe amaphethini okuhweba kwesifunda sase-Asia Pacific.

Ungathanda ukusebenzisa imodi yomsebenzi womsebenzi ukuze upholishe lezi zihloko zezindaba, uthuthukise ukushelela kwemisho futhi wengeze ezinye izihloko zezindaba zokukhishwa?
