I-Acetic Acid Yokusetshenziswa Kwezimboni

I-acetic acid, eyaziwa nangokuthi i-acetic acid, iyinhlanganisela yezinto eziphilayo ezihlukahlukene futhi isetshenziswa ezimbonini ezihlukahlukene. Inefomula yamakhemikhali ethi CH3COOH futhi iyi-organic monobasic acid eyisithako esiyinhloko kuviniga. Lolu ketshezi oluwuketshezi olungenambala lushintsha lube uhlobo oluyikristalu lapho luqina futhi lubhekwa njengento ene-asidi kancane futhi egqwala kakhulu. Kumele iphathwe ngokucophelela ngenxa yamandla ayo okucasula iso nekhala.

Ukusetshenziswa

Okunye ukusetshenziswa okuyinhloko kwe-acetic acid ukukhiqizwa kwe-acetic anhydride, i-acetate esters, ne-cellulose acetate. Lezi ziphuma zisetshenziswa kakhulu embonini yezingubo zokugqoka 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.
