I-sodium acetate iyinto engenziwa kalula ngeviniga ne-baking soda. Njengoba ingxube iphola ngaphansi kwendawo yayo yokuncibilika, icwebezela. I-Crystallization iyinqubo ye-exothermic, ngakho lawa makristalu empeleni akhiqiza ukushisa, yingakho into evame ukubizwa ngokuthi iqhwa elishisayo. Le nhlanganisela inezinhlobonhlobo zezimboni kanye nokusetshenziswa kwansuku zonke.
Ukusetshenziswa Main
Embonini yokudla, i-sodium acetate isetshenziswa njenge-preservative and pickling agent. Ngenxa yokuthi usawoti usiza ukudla ukugcina i-pH ethile, uvimbela amagciwane ayingozi ekukhuleni. Enqubweni yokukhetha, inani elikhulu laleli khemikhali lisetshenziswa, hhayi nje njengesivikelo sokudla kanye nama-microorganisms, kodwa futhi ukuthuthukisa ukunambitheka kokudla.
Njenge-ejenti yokuhlanza, i-sodium acetate inciphisa inani elikhulu le-sulfuric acid ekhishwa ezimbonini. Igcina insimbi ecwebezelayo ngokususa ukugqwala namabala. Ingatholakala nasezisombululweni zokushukwa kwesikhumba kanye nezixazululo zokucubungula izithombe.
Izinkampani eziningi zokuvikela imvelo zisebenzisa i-sodium acetate ekuhlanzeni amanzi angcolile. Yiziphi izinto ezisetshenziswa kakhulu nezindlela zokusebenzisa nezinkomba?
Isixazululo se-sodium acetate
Ukusetshenziswa okuyinhloko:
Imiphumela yeminyaka yodaka (SRT) kanye nomthombo owengeziwe wekhabhoni (isixazululo se-acetate ye-sodium) ekukhishweni kwe-nitrogen ne-phosphorus kwafundwa. I-sodium acetate yasetshenziswa njengomthombo wekhabhoni ukuze ijwayeze udaka lwe-denitrification, kwase kuthi ukukhuphuka kwenani le-pH kulawulwa ngaphakathi kuka-0.5 ngesixazululo sebhafa. I-Denitriifying bacteria ingamunca ngokweqile i-CH3COONa, ngakho-ke inani le-COD elingcolile lingagcinwa lisezingeni eliphansi lapho i-CH3COONA isetshenziswa njengomthombo owengeziwe wekhabhoni wokukhishwa kwe-denitrification. Njengamanje, ukuthuthwa kwendle kwawo wonke amadolobha nezifunda kudinga ukwengeza i-acetate ye-sodium njengomthombo wekhabhoni uma ifuna ukuhlangabezana nezinga lokukhishwa kwe-I.
Izinkomba eziyinhloko: Okuqukethwe: Okuqukethwe ≥20%, 25%, 30% Ukubukeka: uketshezi olucacile nolusobala. Izinzwa: alikho iphunga elicasulayo. Amanzi angancibiliki: ≤0.006%
Izinyathelo zokuvikela isitoreji: Lo mkhiqizo awunabo ubufakazi bokuvuza futhi kufanele ugcinwe endaweni yokugcina umoya. Khumula izingubo ezingcolile ngokushesha ngangokunokwenzeka ngemva komsebenzi, futhi uzihlanze ngaphambi kokuba uzigqoke noma uzilahle. Gqoka amagilavu enjoloba uma usebenzisa.
I-sodium acetate eqinile
1, i-sodium acetate trihydrate eqinile
Ukusetshenziswa okuyinhloko:
Isetshenziswa kakhulu ekunyatheliseni nasekudayeni, imithi, amalungiselelo amakhemikhali, ama-catalysts ezimbonini, izithasiselo, izithasiselo kanye nama-preservatives, kodwa futhi asetshenziswa kabanzi ekuhlanzeni amanzi angcolile, imboni yamakhemikhali amalahle kanye nokulungiswa kwezinto zokugcina amandla kanye neminye imikhakha.
Inkomba eyinhloko: Okuqukethwe: okuqukethwe ≥58-60% Ukubukeka: ikristalu ekhanyayo engenambala noma emhlophe. Izinga lokuncibilika: 58°C. Ukunyibilika kwamanzi: 762g/L (20°C)
2, i-anhydrous sodium acetate
Ukusetshenziswa okuyinhloko:
Ukuhlanganiswa kwe-Organic ye-esterifying ejenti, umuthi, i-mordant yokudaya, i-buffer, i-reagent yamakhemikhali.
