▶Indasteri
Sodium acetate e sebelisoa indastering ea masela ho fokotsa litšila tsa sulfuric acid hape joalo ka photoresist ha ho sebelisoa lidae tsa aniline.Hape ke sesebelisoa sa ho khetha chrome mme e thusa ho sitisa vulcanization ea chloroprene tlhahiso ea rabara ea maiketsetso.Ha ho etsoa k'hothone bakeng sa liphaephe tsa k'hothone tse lahliloeng, acetate ea sodium e sebelisoa ho felisa ho bokellana ha motlakase o tsitsitseng.E boetse e sebelisoa e le "hot-ice" ka mochesong oa letsoho.

▶ Bophelo bo bolelele ba konkreite
Sodium acetate e sebelisoa ho fokotsa tšenyo ea metsi ho konkreite ka ho sebetsa joalo ka sekontiri sa konkreite, ha e ntse e le ntle le tikoloho ebile e le theko e tlase ho feta mokhoa o tloaelehileng o sebelisoang oa epoxy bakeng sa ho tiisa konkreite khahlano le ho kenella ha metsi.
▶Tharollo ea buffer
E le setsi sa conjugate sa acetic acid, tharollo ea sodium acetate le acetic acid e ka sebetsa e le tšireletso ho boloka pH e batlang e sa fetohe.Sena se bohlokoa haholo ts'ebetsong ea lik'hemik'hale tsa biochemical moo liphetoho li itšetlehileng ka pH sebakeng sa asiti e nyane (pH 4-6).E boetse e sebelisoa ho bareki ba HEATING PADS kapa lifuthumatsi tsa matsoho 'me e boetse e sebelisoa ka leqhoa le chesang.Sodium acetate trihydrate crystals e qhibiliha ka 58 °C, e qhibiliha ka metsing a bona a crystallization.Ha li futhumetse ho fihlela ho 100 ° C, 'me ka mor'a moo li lumelloa ho pholile, tharollo e nang le metsi e fetoha supersaturated.Tharollo ena e khona ho pholile haholo ho mocheso oa kamore ntle le ho etsa likristale.Ka ho tobetsa ka tšepe disc ka futhumatsang pad, setsi sa nucleation e thehoa e leng etsa hore tharollo crystallize ka kristale tiileng trihydrate kristale hape.Ts'ebetso ea ho theha maqhama ea crystallization ke exothermic, ka hona mocheso o tsoa.Mocheso o ipatileng oa fusion o ka ba 264-289 kJ/kg.
