Dab tsi yog lub luag haujlwm ntawm sodium acetate hauv kev kho dej phwj,
Suav sodium acetate tov, Suav teb sodium acetate lwm tus neeg, Sodium Acetate, sodium acetate cuam tshuam, sodium acetate cuam tshuam thiab siv, Sodium acetate manufacturers, Sodium Acetate Solution, sodium acetate tov manufacturers, sodium acetate cov neeg muag khoom, siv sodium acetate,
1. Cov cim tseem ceeb:
Cov ntsiab lus: ≥20%, ≥25%, ≥30%
Cov tsos mob: ntshiab thiab pob tshab kua, tsis muaj ntxhiab tsw ntxhiab.
Cov dej tsis muaj dej: ≤0.006%

2. Lub hom phiaj tseem ceeb:
Txhawm rau kho cov dej phwj hauv nroog, kawm txog kev cuam tshuam ntawm cov hnub nyoog sludge (SRT) thiab cov pa roj carbon monoxide (sodium acetate solution) ntawm qhov system denitrification thiab phosphorus tshem tawm. Sodium acetate yog siv los ua cov pa roj carbon monoxide ntxiv rau kev ua kom cov sludge denitrification, thiab tom qab ntawd siv cov tshuaj tsis haum los tswj qhov nce hauv pH thaum lub sij hawm denitrification hauv thaj tsam ntawm 0.5. Cov kab mob denitrifying tuaj yeem adsorb CH3COONa ntau dhau, yog li thaum siv CH3COONa ua cov pa roj carbon monoxide sab nraud rau denitrification, tus nqi COD effluent kuj tseem tuaj yeem khaws cia ntawm qib qis. Tam sim no, kev kho cov dej phwj tuaj hauv txhua lub nroog thiab cov nroog yuav tsum tau ntxiv sodium acetate ua cov pa roj carbon monoxide kom ua tau raws li cov qauv emissions thawj theem.

Nws tsuas yog ua lub luag haujlwm hauv kev tswj hwm tus nqi PH ntawm cov dej phwj tuaj. Sodium acetate yog ib qho tshuaj alkaline uas tuaj yeem ua rau hydrolyzed los ua OH- tsis zoo ions hauv dej, uas tuaj yeem cuam tshuam cov acidic ions hauv dej, xws li H + thiab NH4 +. Qhov sib npaug hydrolysis ntawm sodium acetate yog CH3COO- + H2O = thim rov qab = CH3COOH + OH-

Cov ntaub ntawv txuas ntxiv

siv

1. Kev txiav txim siab ntawm txhuas, zinc, txhuas, hlau, cobalt, antimony, npib tsib xee thiab tin. Complex stabilizer. Tus neeg sawv cev pabcuam ntawm acetylation, tsis, desiccant, mordant.

2, siv rau kev txiav txim siab ntawm txhuas, zinc, txhuas, hlau, cobalt, antimony, npib tsib xee, tin. Siv los ua esterification tus neeg saib xyuas rau cov organic synthesis thiab cov tshuaj yees duab, tshuaj, luam ntawv thiab dyeing mordant, tsis muaj tus neeg sawv cev, tshuaj reagent, nqaij anticorrosion, pigment, tanning tawv thiab ntau lwm yam.

3, siv los ua tus neeg sawv cev buffering, seasoning agent, fragrance enhancer thiab ph regulator. Raws li tus neeg sawv cev buffering, nws tuaj yeem txo cov ntxhiab tsw thiab tiv thaiv kom tsis txhob muaj xim los txhim kho tsw thaum siv los ntawm 0.1% ~ 0.3%. Nws muaj qee yam pov thawj ntawm mildew, xws li siv 0.1% ~ 0.3% hauv cov ntses minced nqaij cov khoom thiab qhob cij.

4, siv los ua leej faj tswj cov neoprene roj hmab coking tus neeg saib xyuas, qhov ntau npaum li cas yog 0.5 loj. Nws kuj tseem siv tau los ua tus neeg sawv cev crosslinking rau tsiaj cov kua nplaum.

5, cov khoom no tuaj yeem siv rau alkaline plating tin ntxiv, tab sis tsis muaj qhov cuam tshuam rau cov txheej txheem plating thiab plating, tsis yog cov khoom tsim nyog. Sodium acetate feem ntau yog siv los ua qhov tsis zoo, xws li hauv cov kua qaub galvanizing, alkaline tin plating thiab electroless npib tsib xee plating.
