Kuyang'anitsitsa Mozama za Unyolo Wapadziko Lonse wa Mafakitale a Acetic Acid: Kutsika kwa Kupanga Kumathandizira Kufunika, Mikangano Yamalonda ndi Kupsinjika kwa Mtengo Kukupitirirabe

Acetic acid ndiye asidi wofunikira kwambiri padziko lonse lapansi, wogwiritsidwa ntchito kwambiri mu PTA, vinyl acetate, zokutira ndi inki, kusindikiza ndi kuyika utoto wa nsalu, zosungira chakudya ndi kupanga mankhwala. Unyolo wake wa mafakitale umagwirizana kwambiri ndi methanol ndi ethanol. Methanol carbonylation ikuyimira ukadaulo waukulu wopanga, womwe umapanga pafupifupi 90% ya mphamvu yapadziko lonse lapansi. Kusakhazikika kwa mitengo ya Methanol kumapita mwachindunji kumitengo ya acetic acid, zomwe zimawonetsa gawoli ndi makhalidwe amphamvu ozungulira. Pakugwiritsa ntchito acetic acid padziko lonse lapansi, Asia Pacific imawerengera 34.6% ya kuchuluka konse. Makampani opanga zinthu ku China, South Korea ndi Southeast Asia ndi omwe amagwiritsa ntchito kwambiri, ndipo kutukuka kwa msika kumatsimikiziridwa ndi magawo okutira, ma polima ndi nsalu.

Kumbali yopereka, mphamvu ya acetic acid padziko lonse lapansi imapezeka ku East Asia ndi North America. Kuwonjezeka kwa mphamvu zatsopano ku Asia m'zaka zaposachedwapa kumapereka mphamvu zokwanira padziko lonse lapansi, koma kusokonekera kwa methanol m'zinthu zopangira kumayambitsa kusinthasintha kwa magwiridwe antchito nthawi ndi nthawi. Kuchepa kwa mphamvu ya methanol ku Middle East mu 2026 kunakweza mtengo wa chakudya cha methanol kunja kwa dziko, zomwe zinakweza mitengo ya acetic acid ku Europe ndi America. Kukwanira kwa mphamvu ya m'deralo ku Asia kumapanga mipata yoonekeratu yamitengo m'madera osiyanasiyana. Mawindo a arbitrage m'madera osiyanasiyana nthawi zambiri amatsegulidwa, zomwe zimapangitsa kuti katundu wambiri wochokera ku Asia atumizidwe kunja.

Magawo ang'onoang'ono omwe ali pansi pa mtsinje akuwonetsa magwiridwe antchito osiyanasiyana. Kufunika kwa utomoni wa vinyl acetate EVA kumakhalabe kolimba; kufunikira kwa filimu yolumikizira kuwala kwa dzuwa kumawonjezera kugwiritsidwa ntchito kwa EVA ndikukweza kugwiritsa ntchito kwa acetic acid mwanjira ina. Magawo opaka utoto, inki ndi utoto wa nsalu amasinthasintha pambuyo pa magawo opanga zinthu. Asidi wa acetic acid wofunikira pakukometsera chakudya ndi kusunga chakudya amasunga kukula kokhazikika. Zinthu zochokera ku acetic acid monga ethyl acetate zimalembetsa kuchuluka kwa zinthu zomwe zimatumizidwa kunja, komabe zoopsa za kukangana kwa malonda apadziko lonse lapansi zimawonjezeka. Mu Ogasiti 2026, Korea Trade Commission idayambitsa kafukufuku wotsutsana ndi kutaya zinyalala wolunjika ku ethyl acetate yochokera ku China. Izi zisintha kwakanthawi kayendedwe ka malonda am'deralo, ndi katundu wochepa kubwerera kumisika yam'nyumba ndikusintha machitidwe amalonda am'chigawo cha Asia Pacific.

Kodi mukufuna kugwiritsa ntchito njira yogwirira ntchito kuti muwongolere nkhani izi, kukonza bwino ziganizo ndikuwonjezera mitu ina yoti itulutsidwe?
