Sodium acetate ndi chinthu chomwe chingapangidwe mosavuta ndi viniga ndi soda. Pamene chisakanizocho chikazizira pansi pa malo ake osungunuka, chimanyezimira. Crystallization ndi njira exothermic, kotero makhiristo amenewa kwenikweni kutenthetsa, ndichifukwa chake zinthu nthawi zambiri amatchedwa otentha ayezi. Pagululi lili ndi ntchito zosiyanasiyana zamakampani komanso tsiku lililonse.
Kugwiritsa ntchito kwakukulu
M'makampani azakudya, sodium acetate imagwiritsidwa ntchito ngati chosungira komanso chotsogola. Chifukwa mchere umathandizira zakudya kukhala ndi pH yeniyeni, umalepheretsa mabakiteriya owopsa kuti asakule. Mu pickling, kuchuluka kwa mankhwalawa kumagwiritsidwa ntchito, osati ngati chotchingira chakudya ndi tizilombo tating'onoting'ono, komanso kukonza kukoma kwa chakudya.
Monga choyeretsera, sodium acetate imachepetsa kuchuluka kwa sulfuric acid yomwe imachokera ku mafakitale. Imasunga chitsulo chonyezimira pochotsa dzimbiri ndi madontho. Itha kupezekanso muzothetsera zowotcha zikopa ndi njira zopangira zithunzi.
Makampani ambiri oteteza zachilengedwe amagwiritsa ntchito sodium acetate pochiza madzi oyipa. Kodi zazikulu zomwe zimagwiritsidwa ntchito ndi njira zogwiritsira ntchito ndi zizindikiro ndi ziti?
Sodium acetate solution
Zogwiritsa ntchito kwambiri:
Zotsatira za zaka zamatope (SRT) ndi zowonjezera carbon source (sodium acetate solution) pa kuchotsa nayitrogeni ndi phosphorous zinaphunziridwa. Sodium acetate idagwiritsidwa ntchito ngati gwero la kaboni kuti igwirizane ndi denitrification sludge, kenako kukwera kwa pH kumayendetsedwa mkati mwa 0.5 ndi yankho la bafa. Tizilombo toyambitsa matenda timatha kuyamwa CH3COONa, kotero kuti mtengo wa COD ukhoza kusungidwabe pamlingo wochepa pamene CH3COONA imagwiritsidwa ntchito ngati gwero lowonjezera la kaboni pakuletsa denitrification. Pakalipano, kuyeretsa kwachimbudzi m'mizinda yonse ndi zigawo ziyenera kuwonjezera acetate ya sodium ngati gwero la carbon ngati ikufuna kukwaniritsa mulingo wa I.
Zizindikiro zazikulu: Zomwe zili: Zomwe zili ≥20%, 25%, 30% Mawonekedwe: madzi omveka bwino komanso owonekera. Zomverera: palibe fungo loyipa. Madzi osasungunuka kanthu: ≤0.006%
Njira zodzitetezera posungira: Chogulitsachi ndi umboni wokwanira wotayikira ndipo chikuyenera kusungidwa m'malo opanda mpweya. Chotsani zovala zomwe zili ndi kachilombo msanga mukangomaliza ntchito, ndipo muzitsuka musanazivale kapena kuzitaya. Valani magolovesi a rabara mukamagwiritsa ntchito.
Sodium acetate yolimba
1, olimba sodium acetate trihydrate
Zogwiritsa ntchito kwambiri:
Amagwiritsidwa ntchito kwambiri kusindikiza ndi utoto, mankhwala, kukonzekera mankhwala, zopangira mafakitale, zowonjezera, zowonjezera ndi zosungirako zosungirako, komanso zimagwiritsidwa ntchito kwambiri pochiza madzi onyansa, mafakitale amagetsi a malasha ndikukonzekera zipangizo zosungiramo mphamvu ndi madera ena.
Mlozera waukulu: Zomwe zili: ≥58-60% Mawonekedwe: kristalo wopanda mtundu kapena woyera wowonekera. Malo osungunuka: 58°C. Kusungunuka kwamadzi: 762g/L (20°C)
2, anhydrous sodium acetate
Zogwiritsa ntchito kwambiri:
Organic kaphatikizidwe wa esterifying wothandizila, mankhwala, utoto mordant, buffer, mankhwala reagent.
