Sodium acetate yog ib yam khoom uas tuaj yeem ua tau yooj yim nrog vinegar thiab ci dej qab zib. Raws li qhov sib tov txias hauv qab nws cov ntsiab lus melting, nws crystallizes. Crystallization yog txheej txheem exothermic, yog li cov crystals no ua kom muaj cua sov, uas yog vim li cas cov khoom no feem ntau hu ua dej khov kub. Cov compound no muaj ntau yam kev lag luam thiab kev siv txhua hnub.
Kev siv tseem ceeb
Hauv kev lag luam khoom noj khoom haus, sodium acetate yog siv los ua cov khoom noj khoom haus thiab khaws cia. Vim tias ntsev pab cov zaub mov kom muaj pH tshwj xeeb, nws tiv thaiv cov kab mob phem los ntawm kev loj hlob. Nyob rau hauv cov txheej txheem pickling, ib tug loj npaum li cas ntawm cov tshuaj no yog siv, tsis tsuas yog raws li ib tug tsis rau zaub mov thiab kab mob, tab sis kuj los txhim kho cov saj ntawm zaub mov.
Raws li tus neeg saib xyuas tu, sodium acetate neutralizes ntau cov sulfuric acid tawm los ntawm cov chaw tsim khoom. Nws tuav lub ci ntsa iab hlau los ntawm kev tshem tawm xeb thiab stains. Nws kuj tuaj yeem pom nyob rau hauv cov kev daws teeb meem tawv tanning thiab cov duab ua kev daws teeb meem.
Ntau lub tuam txhab tiv thaiv ib puag ncig siv sodium acetate rau kev kho dej khib nyiab. Dab tsi yog qhov tseem ceeb ntawm kev siv thiab cov txheej txheem ntawm kev siv thiab kev ntsuas?
Sodium acetate daws
Main siv:
Cov teebmeem ntawm av nkos hnub nyoog (SRT) thiab cov pa roj carbon ntxiv (sodium acetate tov) ntawm nitrogen thiab phosphorus tshem tawm tau kawm. Sodium acetate tau siv los ua cov pa roj carbon monoxide rau acclimate denitrification sludge, thiab tom qab ntawd qhov nce ntawm pH tus nqi raug tswj tsis pub dhau 0.5 los ntawm kev daws teeb meem. Cov kab mob denitrifying tuaj yeem overabsorb CH3COONa, yog li tus nqi COD effluent tuaj yeem tswj tau qis qis thaum CH3COONa siv los ua cov pa roj carbon ntxiv rau denitrification. Tam sim no, kev kho cov dej phwj tuaj ntawm txhua lub nroog thiab cov nroog yuav tsum tau ntxiv sodium acetate los ua cov pa roj carbon monoxide yog tias nws xav ua kom tau raws li qhov tso tawm qib kuv tus qauv.
Cov ntsiab lus tseem ceeb: Cov ntsiab lus: Cov ntsiab lus ≥20%, 25%, 30% Cov tsos mob: cov kua ntshiab thiab pob tshab. Sensory: tsis muaj ntxhiab tsw ntxhiab. Cov dej tsis muaj dej: ≤0.006%
Kev ceev faj cia: Cov khoom no yog cov ntaub ntawv pov thawj nruj heev thiab yuav tsum tau khaws cia rau hauv airtight cia. Tshem cov khaub ncaws tsis huv kom sai li sai tau tom qab ua haujlwm, thiab ntxuav lawv ua ntej hnav lossis muab pov tseg. Hnav hnab looj tes roj hmab thaum siv.
Sodium acetate khoom
1, khoom sodium acetate trihydrate
Main siv:
Siv dav hauv kev luam ntawv thiab dyeing, tshuaj, tshuaj npaj, muaj catalysts, additives, additives thiab preservatives preservatives, tab sis kuj lug siv nyob rau hauv kev kho dej khib nyiab, thee chemical kev lag luam thiab kev npaj ntawm lub zog cia cov ntaub ntawv thiab lwm yam teb.
Lub ntsiab Performance index: Cov ntsiab lus: cov ntsiab lus ≥58-60% Cov tsos: tsis muaj xim lossis dawb pob tshab siv lead ua. Melting point: 58 ° C. Solubility dej: 762g / L (20 ° C)
2, anhydrous sodium acetate
Main siv:
Organic synthesis ntawm esterifying tus neeg sawv cev, tshuaj, dyeing mordant, tsis, tshuaj reagent.
