Ko te waikawa acetic te waikawa waro nui rawa atu o te ao, e whakamahia whānuitia ana i roto i te PTA, te vinyl acetate, ngā paninga me ngā waituhi, te tā me te tae kakahu, ngā mea tiaki kai me te hanga rongoā. He hononga hohonu tōna mekameka ahumahi ki te methanol me te ethanol. Ko te warohanga methanol te hangarau whakaputa matua, e tata ana ki te 90% o te kaha o te ao. Ka tukuna tika te piki me te heke o te utu methanol ki ngā utu i te wā kotahi o te waikawa acetic, e tohu ana i te rāngai me ngā āhuatanga huringa kaha. I roto i te kai waikawa acetic o te ao, ko Āhia Moana-nui-a-Kiwa te 34.6% o te rahinga katoa. Ko ngā ahumahi hanga i Haina, Kōrea ki te Tonga me Āhia ki te Tonga-mā-rāwhiti ngā turanga kai matua, me te whai huatanga o te mākete e whakatauhia ana e ngā paninga, te polymer me ngā rāngai kakahu.
I te taha tuku, ko te kaha o te waikawa acetic o te ao kei Āhia ki te Rawhiti me Amerika ki te Raki. Ko ngā tāpiringa kaha hou o Āhia i ngā tau tata nei ka nui te tuku o te ao, engari ko ngā whakararuraru o ngā rauemi mata methanol ka puta ai ngā piki me ngā heke o te tere mahi. Ko te iti o ngā tuku methanol o te Waenganui Rawhiti i te tau 2026 i whakapiki ake i ngā utu rauemi methanol ki tāwāhi, ka piki ake ngā utu mō te waikawa acetic ki tāwāhi i Ūropi me Amerika. Ko te nui o te kaha o Āhia ā-rohe ka puta he āputa utu ā-rohe. He maha ngā wā ka tuwhera ngā matapihi whakatau ā-rohe, ka akiaki i ngā rahinga nui o ngā utanga mai i Āhia hei kaweake.
He rerekē ngā mahi a ngā rāngai iti o raro. Kei te kaha tonu te tono mō te kapia EVA vinyl acetate; ka whakanui ake ngā whakaritenga kiriata whakakī photovoltaic i te whakamahinga EVA, ā, ka piki ake te whakamahinga waikawa acetic. Ka rerekē haere ngā rāngai paninga, waituhi me te tae kakahu i muri i ngā huringa rāngai hanga. Kei te mau tonu te tipu pumau o te waikawa acetic kai mō te whakakī me te tiaki kai. Kei te rēhitahia ngā rahinga kaweake hohe o ngā waikawa acetic pēnei i te ethyl acetate, engari ka piki ake ngā mōrearea o ngā taupatupatu hokohoko o te ao. I te marama o Ākuhata 2026, i whakarewahia e te Komihana Tauhokohoko o Korea tētahi rangahau ārai-para e aro ana ki te ethyl acetate nō Haina. Ka whakarerekētia e tēnei ngā rere hokohoko ā-rohe mō tētahi wā poto, me te hoki mai o ngā utanga wāhanga ki ngā mākete ā-rohe, me te hanga anō i ngā tauira hokohoko ā-rohe o Āhia Moana-nui-a-Kiwa.
Kei te hiahia koe ki te whakamahi i te aratau mahi hei whakakoi i ēnei tuhinga purongo, hei whakapai ake i te matatau o ngā rerenga kōrero, hei tāpiri atu hoki ki ngā pane kōrero kē atu hei tuku?
