Sodium Acetate, sodium acetate manufacturers, sodium acetate qauv, sodium acetate tus neeg muag khoom,
Physicochemical zog:
1. Tsis muaj xim thiab pob tshab monoclinic prismatic siv lead ua los yog dawb crystalline hmoov, tsis muaj ntxhiab tsw los yog vinegar me ntsis, iab me ntsis, yooj yim rau huab cua qhuav thiab ntub.
2. Solubility dej (46.5g / 100mL, 20 ℃, pH ntawm 0.1mol / L aqueous tov yog 8.87), acetone, thiab lwm yam., soluble nyob rau hauv ethanol, tab sis insoluble nyob rau hauv ether.
3. Melting point (℃): 324
Storge
1. Khaws rau hauv qhov chaw kaw thiab qhuav.
2. Ntim nrog lub hnab yas lined, woven hnab los yog gunny hnab li txheej txheej. Sodium acetate yog deliquescent, yog li nws yuav tsum tau tiv thaiv los ntawm noo noo thaum khaws cia thiab thauj. Nws yog nruj me ntsis txwv tsis pub tiv nrog corrosive gas, tiv thaiv raug tshav ntuj thiab los nag, thiab thauj nws nrog los nag cover.
Siv
1. Kev txiav txim siab ntawm txhuas, zinc, txhuas, hlau, cobalt, antimony, npib tsib xee thiab tin. Complexing stabilizer. Pab, tsis, desiccant, mordant rau acetylation.
2. Siv los txiav txim siab txhuas, zinc, txhuas, hlau, cobalt, antimony, npib tsib xee, thiab tin. Siv los ua tus neeg sawv cev esterification hauv cov organic synthesis thiab ntau yam xws li tshuaj yees duab, tshuaj, luam ntawv thiab dyeing mordants, buffers, tshuaj reagents, nqaij preservatives, pigments, tanning, thiab lwm yam.
3. Siv los ua ib qho tsis, flavoring agent, flavoring agent thiab pH regulator. Raws li tus neeg sawv cev tsis muaj tsw, 0.1% -0.3% tuaj yeem siv los txo cov ntxhiab tsw phem thiab tiv thaiv kom tsis muaj xim los txhim kho tsw. Nws muaj qee yam kev tiv thaiv pwm, xws li siv 0.1%-0.3% hauv cov khoom surimi thiab khob cij. Nws kuj tseem siv tau los ua cov kua qaub rau seasoning sauce, sauerkraut, mayonnaise, ntses ncuav mog qab zib, hnyuv ntxwm, qhob cij, nplaum nplaum, thiab lwm yam. Sib xyaw nrog methyl cellulose, phosphate, thiab lwm yam, siv los txhim kho kev khaws cov hnyuv ntxwm, qhob cij, nplaum. ncuav mog qab zib thiab lwm yam.
4. Siv ua scorch inhibitor rau sulfur-regulated chloroprene roj hmab coking. Qhov ntau npaum li cas feem ntau yog 0.5 feem ntawm qhov 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 los ntxiv alkaline electroplating tin, tab sis nws tsis muaj qhov pom tseeb ntawm txheej txheej txheej txheej thiab electroplating, thiab nws tsis yog qhov tsim nyog. Sodium acetate feem ntau yog siv los ua qhov tsis zoo, xws li acid zinc plating, alkaline tin plating thiab electroless npib tsib xee plating.

Rau cov neeg paub txog sodium acetate, sodium acetate, tseem hu ua sodium acetate, yog siv nyob rau hauv ntau yam kev siv, nrog rau kev yees duab studios, chav ua noj decontamination, dej phwj kho mob, thiab txawm nyob rau hauv cov khoom noj.
Ntau lub khw muag khoom noj yuav dehydrogenate sodium acetate thiaj li ua kom cov zaub mov zoo cia. Yog li ntawd, nws yog hu ua sodium dehydrogenate hauv kev lag luam khoom noj. Nws yog indispensable nyob rau hauv txoj kev loj hlob ntawm cov zaub mov kev lag luam.
Sodium dehydroacetate yog ib qho ntawm cov khoom pov thawj tshaj plaws hauv kev lag luam. Nws muaj cov txiaj ntsig hauv qab no hauv kev lag luam zaub mov:
1. Nws muaj peev xwm inhibit fungi
2. Nws tsis tawg thaum lub sij hawm ua zaub mov
3. Nws yuav tsis evaporate nyob rau hauv kev sib cuag nrog dej
4. Kev ruaj khov, thaum cua sov tuaj yeem ua kom tsis txhob ua kom cov zaub mov puas.
Ntau lub tuam txhab yuav xav tias sodium acetate tom qab yuav cov xim sodium acetate tsis zoo, qhov no yog vim sodium acetate yog soluble hauv dej heev, thaum ntsib lwm yam xim sib txawv ntawm cov hlau, sodium acetate yuav muaj lwm yam xim tshwm, xim zoo li me ntsis. zoo li sodium acetate, yog siv los ua haujlwm nruj heev, qhov xwm txheej no qhia tias peb yuav tsum ceev faj!
Tsis tas li ntawd, sodium acetate peb yuav los ntawm lub Hoobkas yuav tsum tau khaws cia kom zoo, kom tsis txhob muaj xim.
Thaum nws los txog rau kev khaws cia ntawm sodium acetate, kuv tseem pom zoo kom tsim nyog thiab raug txoj kev cia:
1. Sodium acetate nco ntsoov tsis txhob kov cov dej, yog li peb yuav tsum tau muab kaw thiab qhuav nyob rau hauv cov xwm txheej ntawm kev khaws cia.
2 yuav tsum tau xyuam xim rau nws hauv kev thauj mus los los ua kev ntsuas dej noo, sodium acetate tseem ntshai heev ntawm cov dej ntws, tab sis kuj tsis tuaj yeem raug tshav ntuj thiab los nag, hauv kev thauj mus los los muab kev tiv thaiv zoo, thiaj li ua kom muaj kev tiv thaiv zoo. purity ntawm sodium acetate.
3. Nyob rau hauv tus txheej txheem ntawm peb kev thauj mus los, peb yuav tsum nco ntsoov xyuas lub ntim ntawm sodium acetate nyob rau hauv lub sij hawm. Tsuas yog peb mob siab rau xyuas, peb tuaj yeem zam tsis txhob cuam tshuam rau lub xeev ruaj khov ntawm sodium acetate thiab ua rau peb poob vim yog lub hnab ntim khoom tawg thiab qias neeg.
Hauv kev xaiv ntawmsodium acetate manufacturerss, peb yuav tsum polish peb ob lub qhov muag kom nrhiav tau cov manufacturers txhim khu kev qha, Kuv tau pom ntau manufacturers yog pom cov neeg thov rau sodium acetate ntawm tus nqi, hom manufacturers tsis pom zoo kom koj xaiv.
Thaum peb xaiv sodium acetate manufacturers, peb yuav tsum nco ntsoov xaiv manufacturers nrog cov khoom zoo, zoo zoo, zoo lub koob npe nrov thiab tus nqi raws li peb cov kev cia siab. Feem ntau, cov tuam txhab lag luam zoo li no yuav yog ib qho ntawm kev tsim khoom thiab muag khoom, thiab kev tiv thaiv tom qab muag, thiab yuav tsis cia cov neeg siv khoom raug kev txom nyem.
