Ukusetshenziswa
Okunye ukusetshenziswa okuyinhloko kwe-acetic acid ukukhiqizwa kwe-acetic anhydride, i-acetate esters, ne-cellulose acetate.Lezi ziphuma zisetshenziswa kakhulu embonini yokumboza futhi zisiza ekuthuthukisweni kwezinga eliphezulu, ezihlala isikhathi eside.I-acetic anhydride iyisithako esibalulekile ekukhiqizeni izinto ezigcina izinkuni, kuyilapho i-cellulose acetate isetshenziswa ekwenzeni amapende, ama-primers nama-varnish.Ngokwamukela imikhiqizo esekwe ku-acetate, izimboni zingathuthukisa ukusebenza kahle, ukuphila isikhathi eside kanye nokukhanga okuphelele kwezicelo zazo zokuhlanganisa.
Ngaphezu kwalokho, i-acetic acid isetshenziswa kabanzi ekukhiqizeni ama-acetate.I-Acetate inohlu olubanzi lwezinhlelo zokusebenza ezihlanganisa ukusetshenziswa njengesinyibilikisi ekwenzeni amakhemikhali ahlukahlukene, ikakhulukazi ezimbonini ezithaka imithi nezinhle kakhulu.Ngaphezu kwalokho, ingasetshenziswa njengento eluhlaza ekukhiqizeni okunamathelayo, okokugqoka kanye namapulasitiki.Imikhiqizo ye-acetate yaziwa ngokuhlanzeka kwayo okuphezulu, ukuzinza nokuguquguquka, okuyenza ibe ukukhetha okuhle kakhulu kwezidingo ezahlukahlukene zezimboni.
Ngaphezu kwalezi zinhlelo zokusebenza, i-acetic acid iyisithako esibalulekile kuma-reagents okuhlaziya, ukuhlanganiswa kwe-organic, kanye nokuhlanganiswa kwezingulube nemithi.Izakhiwo zayo zikwenza kube lula ukusabela okuhlukahlukene kwamakhemikhali nezinqubo zokwenziwa.Isiza ukukhiqiza ama-pigments asetshenziswa opende, oyinki kanye nodayi, ibanike imibala egqamile futhi ehlala isikhathi eside.Ngaphezu kwalokho, i-acetic acid isetshenziswa ekuhlanganiseni izidakamizwa futhi idlala indima ebalulekile ekwakhiweni kwezidakamizwa ezithuthukisa izinga lempilo yabantu emhlabeni wonke.
Sengiphetha, i-acetic acid iyinhlanganisela ebalulekile yemvelo enendawo ezimbonini eziningi.Izicelo zayo zisukela ekukhiqizweni kwe-acetic anhydride, i-acetates kanye ne-cellulose acetates embonini kapende kuya kuma-reagents okuhlaziya, ukuhlanganiswa kwezinto eziphilayo kanye nokuhlanganiswa kwezingulube nemithi.Ngezakhiwo nemisebenzi ehlukahlukene, i-acetic acid ikhombisa ukuthi iyisithako esibalulekile kumabhizinisi afuna ukuthuthukisa imikhiqizo nezinqubo zawo.Nokho, kubalulekile ukuphatha i-acetic ngokucophelela ngoba iyagqwala futhi ingase icasule.
