Chaw tsim tshuaj paus zoo Sodium Sesqui Carbon Carbonate CAS: 533-96-0

Cov lus piav qhia luv luv:

Sodium Sesqui Carbonate, Alias, yog sodium ntawm sodium carbonate, thiab cov mis molecular yog Na2Chox · 2Ch2o. Bicarbonate sodium yog tshuaj lom neeg ntawm rab koob dawb koob -Sped muaju, ntawv-zoo li hmoov lossis crystalline hmoov. Tus txheeb ze cov molecular loj yog 226.03, thiab cov kev txheeb ze yog 2.112. Ntawm 100 ° C, nws yog 42%. Cov kua aqueous yog alkaline, thiab nws cov alkali tsis muaj zog tshaj sodium carbonate. Nws yog tsim los ntawm qee qhov kev faib ua feem ntawm sodium carbonate thiab sodium bicarbonate daws.

Cov yam ntxwv: sodium sesqui carbon carbonate yog dawb koob siv lead ua siv lead ua, sheet-zoo li hmoov. Cov txheeb ze ceev yog 2.112, uas tsis yooj yim rau huab cua. Ntawm 42% ntawm ° C, cov kua aqueous yog alkaline yog alkaline, thiab sodium bicarbonate yog tsis muaj zog dua sodium carbonate.

Cov ntawv thov ntawm sodium sesqui carbon carbonate

Siv nyob rau hauv cov ntsev da dej thiab tshuaj, Alkali muag muag tawv, cov khoom noj ua haus dej tseem ceeb, cov khoom siv ua haujlwm loj ntawm cov khoom siv ntxuav tawm thiab cov ntaub npuag, zas plaub hau, Kev ntxuav (Wool yaug, thiab lwm yam) ntxiv, nroog loj thiab cov roj ntsha dej phwj thiab pub ntxiv; Haum rau txhua yam ntxuav, kev tshem tawm thiab txhuam cov kev ua haujlwm xav tau kev siv cov khoom siv tsis muaj zog (seb xab npum li xab npum lossis tsis yog). Nyob rau hauv xyoo tsis ntev los no, raws li ib qho tshiab ntawm cov ntsev da dej tau siv dav hauv Nyij Pooj thiab Kaus Lim Qab Teb.

Sopium Sesqui Carbonate Txoj Kev: Hauv txoj kev ntawm ntuj alkali. Thawj zaug tsoo lub ntuj alkali ore rau qee yam granularity (txog 0.8mm). Tom qab disspact, hais meej, thiab lim, ib qho nqi ntawm cov pob zeb siv lead ua (etcic alkyl Tos, tom qab evaporation yas thiab leej niam sib cais kua, peb tuaj yeem tau txais ob npaug sodium carbonate lim cov khoom qab zib carbon carbonate lim cov inorganic impurities. Cov khoom noj khoom haus khwv tau los tuaj yeem ua tau hnyav, muaju thiab qhuav, thiab tau txais ntau cov khoom so suab, uas yog siv rau kev kho dej lossis tsim khoom. Hlawv sodium carbonate lim cov khoom qab zib tuaj yeem hlawv cov khoom kub sib txawv (li 200 ° C) tuaj yeem tau txais cov roj sib txawv (0.8 ~ 1.0g / cm3).
