Sodium acetate chinhu chinogona kugadzirwa nyore nevhiniga nesoda yekubheka. Sezvo musanganiswa wacho unotonhora pasi penzvimbo yayo yekunyungudika, inopenya. Crystallization ndeye exothermic process, saka makristasi aya anoburitsa kupisa, ndosaka chinhu ichi chinowanzonzi inopisa ice. Mushonga uyu une zvakasiyana siyana zvemaindasitiri uye zvemazuva ese kushandiswa.
Main kushandiswa
Muindasitiri yezvekudya, sodium acetate inoshandiswa sechinhu chekuchengetedza uye pickling agent. Nekuti munyu unobatsira chikafu kuchengetedza chaiyo pH, inodzivirira mabhakitiriya anokuvadza kubva pakukura. Mukuita pickling, yakawanda yekemikari iyi inoshandiswa, kwete chete sebuffer yezvokudya uye microorganisms, asiwo kuvandudza kuravira kwechikafu.
Semugadziri wekuchenesa, sodium acetate inoderedza huwandu hukuru hwesarufa asidhi inoburitswa kubva mumafekitori. Inochengetedza simbi inopenya nekubvisa ngura uye mavara. Inogonawo kuwanikwa mumatehwe ekutsvukisa mhinduro uye mifananidzo yekugadzirisa mhinduro.
Mazhinji makambani ekuchengetedza zvakatipoteredza anoshandisa sodium acetate pakurapa mvura yetsvina. Ndezvipi zvinonyanya kushandiswa uye nzira dzekushandisa uye zviratidzo?
Sodium acetate solution
Main kushandiswa:
Mhedzisiro yezera rematope (SRT) uye yakawedzera kabhoni sosi (sodium acetate solution) pane nitrogen uye phosphorus kubviswa zvakadzidzwa. Sodium acetate yakashandiswa sekabhoni sosi kukwenenzvera denitrification sludge, uyezve kukwira kwepH kukosha kwakadzorwa mukati me0.5 nebuffer solution. Denitrifying mabhakitiriya anogona kunyudza CH3COONa, saka iyo effluent COD kukosha inogona kuchengetedzwa padanho rakaderera kana CH3COONA ichishandiswa seyekuwedzera kabhoni sosi ye denitrification. Parizvino, kurapwa kwetsvina kwemaguta ese nemataundi kunoda kuwedzera sodium acetate senge kabhoni sosi kana ichida kusangana neiyo yekuburitsa level I standard.
Zviratidzo zvikuru: Zviri mukati: Zviri mukati ≥20%, 25%, 30% Kuonekwa: mvura yakajeka uye yakajeka. Sensory: hapana kunhuhwirira. Mvura isinganyunguriki chinhu: ≤0.006%
Chengetedzo yekuchengetera: Ichi chigadzirwa hachina kudonhedza humbowo uye chinofanira kuchengetwa munzvimbo isina mhepo. Bvisa hembe dzine utachiona uchangopedza basa, wodzigeza usati wadzipfeka kana kudzikanda. Pfeka magirovhosi erubha paunenge uchishandisa.
Sodium acetate yakasimba
1, yakasimba sodium acetate trihydrate
Main kushandiswa:
Inoshandiswa zvakanyanya mukudhinda uye kudhaya, mushonga, kugadzirira kwemakemikari, maindasitiri zvinokonzeresa, zvinowedzera, zvinowedzera uye zvinochengetedza kuchengetedza, asiwo zvakanyanya kushandiswa mukuchenesa mvura yetsvina, marasha kemikari indasitiri uye kugadzirira kwesimba rekuchengetedza zvinhu nezvimwe minda.
Main index: Content: content ≥58-60% Kuonekwa: isina ruvara kana chena yakajeka crystal. Kunyungudika: 58°C. Kunyungudika kwemvura: 762g/L (20°C)
2, anhydrous sodium acetate
Main kushandiswa:
Organic synthesis ye esterifying agent, mushonga, dhayi mordant, buffer, kemikari reagent.
