Chaw tsim tshuaj paus zoo sodium bicarbonate CAS: 144-55 featured duab

Cov lus piav qhia luv luv:

Sodium bicarbonate, uas yog qhov sib xyaw ua ntej hu ua ci dej qab zib, muaj nyob ua cov dawb, tsis muaj ntxhiab, crystalline khoom. Nws tshwm sim ib txwm ua raws li cov ntxhia cov ntxhia, uas tau txais nws lub npe los ntawm nws cov mis nyuj los hloov "3" hauv Nayco3 nrog xaus "Lite." Lub ntiaj teb lub hauv paus tseem ceeb ntawm Nahcolite yog lub piceance Creek hauv qab, uas yog ib feem ntawm cov dej ntsuab loj dua. Sodium bicarbonate yog muab rho tawm siv kev daws teeb meem los ntawm kev txhaj tshuaj kub los ntawm kev txhaj tshuaj kub kom yaj qhov twg nws tshwm sim 1,500 txog 2,000 ko taw hauv qab saum npoo. Qhov yaj saub sodium bicarbonate tau muab tso rau saum npoo uas nws tau kho kom rov zoo rau Nahco3 los ntawm kev daws teeb meem. Sodium Bicarbonate kuj tseem tuaj yeem tsim los ntawm cov nyiaj hauv TRAAs, uas yog qhov chaw sodium carbonate (saib sodium carbonate).

Tshuaj lom neeg: sodium bicarbonate, Nahc03, tseem muaj cov sodium acid carbonate thiab soling dej qab zib, yog ib qho dawb dioxide ntawm 270 ° F) .and yog siv nyob rau hauv Kev Npaj Khoom Noj Khoom Haus. Sodium Bicarbonate tseem pom siv cov tshuaj, cov tshuaj tua hluav taws xob, hauv cov lus ceramics, thiab kom tiv thaiv cav ntoo pwm.

Synonym: sodium bicarbonate, gr, ≥99.8%; sodium bicarbonate, sdium bicarbonate, sdium bicarbonate tov (chp); sodium bicarbonate chaw tsim tshuaj paus; tseb

Cov ntawv thov ntawm sodium bicarbonate

1. Sodium bicarbonate, siv nyob rau hauv cov formof ci dej qab zib thiab ci hmoov, yog qhov feem ntau cov tshuaj tsuag uas muaj xyoob ntoo. Thaum ci dej qab zib, uas yog ib qho khoom noj khoom haus alkaline, ntxiv rau kev sib xyaw, nws cuam tshuam nrog cov tshuaj muaj kua qaub ua kom tsim khoom. Cov tshuaj tiv thaiv tuaj yeem raug sawv cev raws li: Nahco3 (s) h + → naj npawb rau + (l) + h + yog muab los ntawm cov kua qaub. Ci txau muaj cov dej qab zib muaj cov dej qab zib ua ib qho tseem ceeb nrog cov acid thiab lwm yam khoom xyaw. Ua raws li cov qauv tsim, ci ci tuaj yeem tsim cov pa roj carbon dioxide sai sai sai li ib qho kev nqis tes ua lossis hauv theem, raws li cov hmoov adouble-nqis. Ci Dej qab zib kuj tau siv los ua lub hauv paus rau cov pa roj carbon dioxide rau cov carbon cais rau baking, ci dej qab zib muaj ntau tsev neeg siv. Nws yog siv los ua ib qho chaw muag khoom, ib qho tshuaj antacid, hluav taws kub yog cov tshuaj txhuam hniav li cas xws li 8. TheBicarbonate Ion (HCO3-) muaj amphoter Cov khoom, uas txhais tau tias nws tuaj yeem ua raws li ib qho kua qaub lub hauv paus. Qhov no muab Baking dej qab zib ib buff ering muaj peev xwm thiab muaj peev xwm los nruab nrab ob qho tib si acidsland hauv paus. Cov zaub mov tsw tshwm los ntawm acidic lossis cov kab sib txuas yooj yim tuaj yeem cuam tshuam nrog ci ci rau cov ntsev tsis muaj ntxhiab. Vim hais tias sodium bicarbonate yog lub hauv paus tsis muaj zog, nws muaj lub peev xwm ntau dua neutralize acid tsw.
Qhov loj tshaj plaws ntawm sodium bicarbonate, suav rau kwv yees li 25% ntawm kev ua liaj ua teb, yog ua kev ua liaj ua teb pub. Hauv nyuj nws pab tswj kev rumen p thiab qhia fiber ntau zom; Rau nqaij qaib nws pab tswj cov nyiaj nruab nrab los ntawm kev muab Sodiumin cov zaub mov noj, pab kom fowl zam tshav kub, thiab txhim kho qe zoo.
Sodium Bicarbonate yog siv nyob rau hauv kev lag luam tshuaj lom neeg buff ering tus neeg sawv cev, ib lub tshuab, ib qho catalyst, thiab cov tshuaj lom neeg. Sodium bicarbonate yog siv nyob rau hauv cov tawv tanninginderry rau kev tutorium bicolate yog koom rau hauv cov sodium carbonate, uas tau siv rau hauv khw muag khoom los ua ib qho tshuaj antacid, ua phem Ering tus neeg sawv cev, thiab hauv cov qauv ua ib qho chaw ntawm cov pa roj carbon dioxide hauv eff ervescent ntsiav tshuaj. Drychemical hom BC Tua hluav taws Extingishers muaj sodium bicarbonate (los yog potassium bicarbonate). Kev kho cov tshuaj, dej ntxuav, thiab roj kom zoo.

2. Sodium Bicarbonate yog cov poov xab piv nrog tus ph ntawm kwv yees li 8.5 hauv 1% daws ntawm 25 ° C. Nws ua haujlwm nrog zaub mov Qib phosphates (acidic keeb kwm) kom tso cov pa roj carcon) uas nthuav dav thaum lub sijhawm ua kom zoo thiab kev sib tw noj cov khoom zoo. Nws kuj tseem siv hauv kev sib xyaw qhuav-kom tau txais cov tshuaj carbonation, uas tshwm sim thaum dej ntxiv rau kev sib xyaw sodium bicarbonate thiab cov kua qaub. Nws yog ib feem ntawm ci hmoov. Nws tseem raug muab cov dej qab zib ci, bicarbonate ntawm cov dej qab zib, sodium acid carbonate, thiab sodium hydrogen carbonate.

3. Siv cov ntsev ntau ntau sidium; qhov chaw ntawm CO2; xyaw xyaw ua noj, effervescent salts thiab dej haus; Nyob rau hauv cov tshuab tua hluav taws, ntxuav cov tebchaw.

4. Sodium Bicarbonate (ci dej qab zib) yog cov tshuaj tsw qab inorganic siv los ua tus neeg sawv cev ua kom zoo li tus neeg sawv cev, nws kuj tseem ua haujlwm hauv nruab nrab. Nws yog siv rau hauv daim tawv nqaij-smoothing hmoov.
