Chaw Tsim Khoom Zoo Tus Nqi Sodium Sesqui Carbonate CAS ： 533-96-0

piav qhia luv luv:

Sodium Carbonate Hmoov, alias, yog sodium ntawm sodium carbonate, semi-alkali, thiab cov mis molecular yog NA2CO3 · NAHCO3 · 2H2O. Bicarbonate sodium yog ib qho tshuaj ntawm cov siv lead ua dawb, zoo li daim ntawv lossis hmoov crystalline. Qhov hnyav molecular txheeb ze yog 226.03, thiab qhov ceev txheeb ze yog 2.112. Ntawm 100 ° C, nws yog 42%. Cov kua dej yog alkaline, thiab nws cov alkali yog weaker dua li sodium carbonate. Nws yog ua los ntawm ib qho kev faib ua feem ntawm sodium carbonate thiab sodium bicarbonate kua.

Cov yam ntxwv: Sodium Sesqui Carbonate yog cov siv lead ua dawb zoo li koob, zoo li daim ntawv lossis hmoov crystalline. Qhov ceev ntawm qhov sib piv yog 2.112, uas tsis yooj yim rau huab cua. Ntawm 42% ntawm ° C, cov kua dej yog alkaline, thiab sodium bicarbonate tsis muaj zog dua li sodium carbonate.

Cov Lus Txhais: Carbonicacid, sodiumsalt (2: 3); magadisoda; snowflakecrystals; sq810; Sodium Sesquicarbonate; trisodiumhydrogendicarbonate; urao; SODIUM CARBONATE, SESQUIOXIDE DIHYDRATE

Cov ntawv thov ntawm Sodium Sesqui Carbonate

Siv rau hauv cov ntsev da dej thiab tshuaj, tus neeg sawv cev alkali hauv cov tawv nqaij tanned, dej mos, pas dej ua luam dej thiab dej ntxhia rov qab, cov tshuaj ntxhua khaub ncaws ntxiv, cov khoom xyaw tseem ceeb ntawm cov neeg sawv cev ntxuav kev lag luam, cov khoom xyaw tseem ceeb ntawm cov neeg sawv cev ntxuav qhov chaw tawv, daim ntaub, xim plaub hau, ntxuav (wool rinsing, thiab lwm yam) ntxiv, kev kho dej phwj hauv nroog thiab hauv nroog thiab cov khoom noj ntxiv; Haum rau txhua yam kev ntxuav, tshem tawm cov pa phem thiab txhuam cov haujlwm uas xav tau kev siv cov khoom siv alkaline tsis muaj zog (txawm tias xav tau xab npum lossis tsis xav tau). Nyob rau xyoo tas los no, ua ib hom ntsev da dej tshiab tau siv dav hauv Nyiv Pooj thiab Kaus Lim Qab Teb.

Txoj kev Sodium Sesqui Carbonate: nyob rau hauv txoj kev ntawm cov alkali ntuj. Ua ntej rhuav cov alkali ore ntuj rau qee qhov granularity (kwv yees li 0.8 hli). Tom qab yaj, ua kom meej, thiab lim, ib qho nyiaj ntawm cov khoom siv crystal (xws li sodium alkyl sulfate, thiab lwm yam), cov neeg sawv cev ua npuas dej thiab cov neeg sawv cev sedimentary ntxiv rau hauv cov lim. Tos, tom qab cov siv lead ua evaporation thiab cov kua niam sib cais, peb tuaj yeem tau txais ob npaug sodium sodium carbonate lim ncuav mog qab zib uas tsis muaj cov khoom tsis huv. Cov ncuav mog qab zib tau txais tuaj yeem yaj hnyav, siv lead ua thiab qhuav, thiab tau txais cov khoom sodium carbonate ntau, uas yog siv rau kev kho dej lossis kev tsim khoom. Hlawv sodium carbonate lim ncuav mog qab zib tuaj yeem hlawv ntawm qhov kub sib txawv (kwv yees li 200 ° C txog 850 ° C) tuaj yeem tau txais cov khoom hnyav nrog qhov sib txawv ntawm qhov ceev (0.8 ～ 1.0g / cm3).
