Isuzuma ryimbitse ku ruhererekane rw'inganda zikomoka kuri aside asetiki ku isi: Inganda zikomeza gukenera, inzitizi mu bucuruzi n'ibiciro biracyari hasi

Aside asetiki ni aside organic y'ingenzi cyane ku isi, ikoreshwa cyane muri PTA, acetate ya vinyl, irangi n'inyindo, icapiro n'irangi ry'imyenda, ibirinda ibiryo no guhuza imiti. Uruhererekane rwayo rw'inganda rufitanye isano rikomeye na methanol na ethanol. Karubone ya Methanol ni ikoranabuhanga rikomeye mu gukora, rigizwe hafi na 90% by'ubushobozi bw'isi yose. Ihindagurika ry'ibiciro bya Methanol rigera ku biciro bya aside asetiki, rigaragaza ko uru rwego rufite imiterere ikomeye. Mu ikoreshwa rya aside asetiki ku isi, muri Aziya ya Pasifika rungana na 34.6% by'ingano yose. Inganda zikora mu Bushinwa, Koreya y'Epfo na Aziya y'Amajyepfo y'Amajyepfo ni zo zishingirwaho mu gukoresha, aho iterambere ry'isoko rishingira ku irangi, polimeri n'imyenda.

Ku ruhande rw'ibicuruzwa, ubushobozi bwa aside asetiki ku isi bwibanda muri Aziya y'Iburasirazuba na Amerika y'Amajyaruguru. Inyongera nshya z'ubushobozi bwa Aziya mu myaka ya vuba aha zitanga umusaruro uhagije ku isi yose, ariko ihungabana ry'ibikoresho fatizo bya methanol ritera ihindagurika ry'umuvuduko w'imikorere. Ibiciro bya methanol byo mu Burasirazuba bwo Hagati mu 2026 byazamuye ikiguzi cy'ibiribwa bya methanol mu mahanga, bituma ibiciro bya aside asetiki mu mahanga byiyongera mu Burayi na Amerika. Ubushobozi buhagije bwo mu karere ka Aziya butuma ibiciro by'ibicuruzwa byo mu karere bigabanuka. Amadirishya ya arbitrage yo mu karere akunze gufungurwa, bigatuma ibicuruzwa byinshi byo muri Aziya bijyanwa mu mahanga.

Ibyiciro bito byo hasi bigaragaza imikorere itandukanye. Ubusabe bwa vinyl acetate EVA resin bukomeje kuba bukomeye; ibisabwa muri firime yo gufunga amashanyarazi byongera ikoreshwa rya EVA kandi bikazamura mu buryo butaziguye ikoreshwa rya aside asetiki. Ingufu zo gusiga, irangi n'ingufu zo gusiga amarangi mu myenda zirahinduka bitewe n'ingendo z'inganda. Aside asetiki yo mu rwego rw'ibiribwa yo guteka no kubungabunga ibiryo bikomeza gukura neza. Ibikomoka kuri aside asetiki nka ethyl acetate byerekana ingano y'ibicuruzwa byoherezwa mu mahanga, ariko ibyago byo kwangirika kw'ubucuruzi mpuzamahanga biriyongera. Muri Kanama 2026, Komisiyo y'Ubucuruzi ya Koreya yatangije iperereza ryo kurwanya ijugunywa ry'ibicuruzwa bikomoka kuri ethyl acetate ikomoka mu Bushinwa. Ibi bizahindura by'agateganyo ubucuruzi bwo mu karere, aho ibice by'imizigo bisubira ku masoko yo mu gihugu no guhindura imiterere y'ubucuruzi bwo mu karere ka Aziya Pasifika.

Wifuza gukoresha uburyo bw'akazi kugira ngo utunganye izi nkuru, wongere interuro nziza kandi wongere izindi nkuru zo gusohora?
