Nā Noi ʻOihana
1. He huahana kemika nui ka waikawa acetic a ʻo ia kekahi o nā waikawa organik koʻikoʻi loa. Hoʻohana nui ʻia no ka hana ʻana o ka acetic anhydride, acetate a me ka cellulose acetate. Hiki ke hana ʻia ka Polyvinyl acetate i nā kiʻiʻoniʻoni a me nā mea hoʻopili, a ʻo ia hoʻi ka mea maka no ka vinylon fiber synthetic. Hoʻohana ʻia ka Cellulose acetate e hana i nā kiʻiʻoniʻoni rayon a me nā kiʻiʻoniʻoni.

2. ʻO ka acetate ester i hana ʻia mai ka waiʻona haʻahaʻa he mea hoʻoheheʻe maikaʻi loa ia a hoʻohana nui ʻia i ka ʻoihana pena. Ma muli o ka hoʻoheheʻe ʻana o ka waikawa acetic i ka hapa nui o nā mea olaola, ʻo ka waikawa acetic kekahi mea hoʻoheheʻe olaola i hoʻohana pinepine ʻia (no ka laʻana, i hoʻohana ʻia i ka oxidation o ka paraxylene e hana i ka waikawa terephthalic).

3. Hiki ke hoʻohana ʻia ka waikawa acetic i kekahi mau hopena pickling a me polishing, ma ke ʻano he buffer i nā hopena acidic nāwaliwali (e like me ka zinc plating, chemical nickel plating), ma ke ʻano he mea hoʻohui i ka electrolyte nickel plating semi-bright, a ma ka passivation o zinc a me cadmium. Hiki i ka hopena ke hoʻomaikaʻi i ka ikaika hoʻopaʻa o ka passivation film a hoʻohana pinepine ʻia e hoʻoponopono i ka pH o nā hopena plating acidic nāwaliwali.

4. Hoʻohana ʻia e hana i ka acetate, e like me nā paʻakai o ka manganese, sodium, kēpau, alumini, zinc, cobalt a me nā metala ʻē aʻe, i hoʻohana nui ʻia e like me nā mea hoʻoulu a me nā mea hoʻohui i ka hoʻoluʻu lole a me nā ʻoihana ʻili ʻili; ʻo ke kēpau acetate ke keʻokeʻo ke kala pena; ʻO ke kēpau tetraacetate kahi mea hana synthesis organik (no ka laʻana, hiki ke hoʻohana ʻia ke kēpau tetraacetate ma ke ʻano he oxidant ikaika, hāʻawi i kahi kumu o nā hui acetoxy, a hoʻomākaukau i nā hui alakaʻi organik, a pēlā aku).

5. Hiki ke hoʻohana ʻia ka waikawa acetic ma ke ʻano he reagents analytical, synthesis organik, synthesis o nā pigments a me nā lāʻau lapaʻau.

Nā Hoʻohana Meaʻai
I ka ʻoihana meaʻai, hoʻohana ʻia ka waikawa acetic ma ke ʻano he mea hoʻohuihui, mea ʻono a me ka mea ʻala. I ka hana ʻana i ka vīnega synthetic, e hoʻoheheʻe i ka waikawa acetic me ka wai i 4-5% a hoʻohui i nā mea ʻono like ʻole. Ua like ka ʻono me ka vīnega i hana ʻia me ka waiʻona, a he pōkole ka manawa hana a he haʻahaʻa ke kumukūʻai. Makepono. Ma ke ʻano he mea ʻawaʻawa, hiki ke hoʻohana ʻia i nā mea ʻala hui e hoʻomākaukau i ka vīnega, ka meaʻai i loko o ka pahu, ka jelly a me ka tīhi. Hiki ke hoʻohana ʻia i nā nui kūpono e like me nā pono hana. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻonui ʻono no ka waina Quxiang, me ka nui o 0.1 a 0.3 g/kg.
