Chaw tsim tshuaj paus Zoo Nqe Sodium Sesqui Carbonate CAS: 533-96-0

piav qhia luv luv:

Sodium Sesqui Carbonate, alias, yog sodium ntawm sodium carbonate, semi-alkali, thiab cov mis molecular yog NA2CO3 · NAHCO3 · 2H2O. Bicarbonate sodium yog ib yam tshuaj ntawm koob dawb-zoo li tus muaju, daim ntawv-zoo li lossis crystalline hmoov. Tus txheeb ze molecular loj yog 226.03, thiab tus txheeb ze ntom yog 2.112. Ntawm 100 ° C, nws yog 42%. Cov tshuaj aqueous yog alkaline, thiab nws cov alkali tsis muaj zog dua li sodium carbonate. Nws yog tsim los ntawm ib feem ntawm sodium carbonate thiab sodium bicarbonate tov.

Yam ntxwv: Sodium Sesqui Carbonate yog ib rab koob dawb zoo li siv lead ua, daim ntawv zoo li los yog crystalline hmoov. Tus txheeb ze ntom ntom yog 2.112, uas tsis yooj yim rau huab cua. Ntawm 42% ntawm ° C, cov tshuaj aqueous yog alkaline, thiab sodium bicarbonate tsis muaj zog dua li sodium carbonate.

Synonyms: Carbonicacid, sodium ntsev (2: 3); magadisoda; snowflakecrystals; sq810; Sodium Sesquicarbonat; trisodiumhydrogendicarbonate; urao; SODIUM CARBONATE, SESQUIOXIDE DIHYDRATE

Kev siv ntawm Sodium Sesqui Carbonate

Siv nyob rau hauv da dej ntsev thiab tshuaj, alkali tus neeg sawv cev nyob rau hauv tanned tawv, dej softening, da dej pas dej ua ke thiab mineral dej recuperation, ntxhua khaub ncaws detergent additives, cov khoom xyaw tseem ceeb ntawm kev lag luam tu tus neeg saib xyuas, cov khoom xyaw tseem ceeb ntawm cov tawv nqaij tu tus neeg saib xyuas, daim duab ntaub, plaub hau zas xim, ntxuav (wool yaug, thiab lwm yam) additives, nroog thiab municipal kev kho mob additives. Tsim nyog rau txhua yam kev ntxuav, tshem tawm thiab txhuam cov haujlwm uas yuav tsum tau siv cov ntaub ntawv tsis muaj zog alkaline (txawm tias yuav tsum tau xab npum lossis tsis xav tau). Nyob rau hauv xyoo tas los no, raws li ib yam tshiab ntawm da dej ntsev yog dav siv nyob rau hauv Nyiv thiab South Kauslim.

Sodium Sesqui Carbonate txoj kev: nyob rau hauv txoj kev ntawm ntuj alkali. Ua ntej tsoo lub ntuj alkali ore mus rau ib qho granularity (li 0.8mm). Tom qab dissolving, clarifying, thiab filtering, ib tug npaum li cas ntawm siv lead ua pab (xws li sodium alkyl sulfate, thiab lwm yam), organic foaming agent thiab sedimentary agent yog ntxiv rau cov filtrate. Tos, tom qab cov evaporation muaju thiab cov kua dej sib cais, peb tuaj yeem tau txais ob chav sodium sodium carbonate lim ncuav qab zib uas tsis muaj inorganic impurities. Lub ncuav mog qab zib cov nyiaj tau los yuav hnyav heev, muaju thiab qhuav, thiab tau txais ntau cov khoom siv sodium carbonate, uas yog siv rau kev kho dej lossis kev tsim khoom. Hlawv sodium carbonate lim ncuav 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 cov khoom sib txawv sib txawv (0.8 ~ 1.0g / cm3).
