Soo saaraha Qiimaha Wanaagsan Sodium Sesqui Carbonate CAS: 533-96-0

sharaxaad gaaban:

Sodium Sesqui Carbonate, alias, waa sodium of sodium carbonate, semi-alkali, iyo formula kelli waa NA2CO3 · NAHCO3 · 2H2O. Soodhiyamka bicarbonate waa kiimiko irbad cad ah oo qaabaysan kareem, xaashi u eg ama budada crystalline. Cufnaanta molecular ee qaraabada ah waa 226.03, iyo cufnaanta qaraabo waa 2.112. Heerkulka 100 ° C, waa 42%. Xalka aqueous waa alkaline, alkalkiisuna wuu ka daciifsan yahay sodium carbonate. Waxaa lagu sameeyaa qayb ka mid ah sodium carbonate iyo xalalka sodium bicarbonate.

Astaamaha: Sodium Sesqui Carbonate waa crystal qaab irbad cad, xaashi u eg ama budo crystalline ah. Cufnaanta qaraabada ah waa 2.112, taas oo aan fududayn cimilada. Marka la joogo 42% at ° C, xalka aqueous waa alkaline, iyo sodium bicarbonate waa daciif ka sodium carbonate.

Ereyada la midka ah: Carbonicacid, sodium cusbo (2: 3); Magdisoda, Snowflakecrystals; sq810; Sodium Sesquicarbonat;

Codsiyada Sodium Sesqui Carbonate

Waxaa loo isticmaalaa cusbada qubeyska iyo daawada, wakiilka alkali ee maqaarka maqaarka, jilicsanaanta biyaha, barkada dabaasha iyo soo kabashada biyaha macdanta, waxyaalaha lagu daro saabuunta dharka, maaddooyinka ugu muhiimsan ee wakiilka nadiifinta warshadaha, maaddooyinka ugu muhiimsan ee wakiilka nadiifinta dusha adag, dharka shaxanka, rinjiga timaha, dhaqida (luqashada dhogorta, iwm.) daroogooyinka, daaweynta wasakhda magaalada iyo degmada iyo wax lagu daro; Ku habboon dhammaan noocyada dhaqidda, sun-saaridda iyo hawlaha xoqidda ee u baahan isticmaalka walxaha alkaline ee daciifka ah (haddii saabuun loo baahan yahay iyo haddii kale). Sanadihii la soo dhaafay, sida nooc cusub oo cusbada qubeyska ah ayaa si weyn looga isticmaalaa Japan iyo South Korea.

Habka Sodium Sesqui Carbonate: habka alkali dabiiciga ah. Marka hore jebi macdanta alkali ee dabiiciga ah ilaa xad gaar ah (qiyaastii 0.8mm). Ka dib marka la kala diro, la caddeeyo, oo la shaandheeyo, qadar go'an oo ah aids crystal (sida sodium alkyl sulfate, iwm.), wakiilka xumbo organic iyo wakiilka sedimentary ayaa lagu daraa sifeynta. Sug, ka dib kiristaalo uumi-baxa iyo kala soocida dareeraha hooyada, waxaan heli karnaa keega filter sodium sodium carbonate double oo aan ku jirin wasakh aan organic ahayn. Keega dakhligu si aad ah ayaa loo milmi karaa, kiristaalo iyo engegan, oo wuxuu heli karaa badeecooyinka kaarboonaytka ee sodium la dhufto, kaas oo loo isticmaalo daaweynta sahayda biyaha ama soo saarista. Gubashada Keega filter-ka karbohaydraytka waxa lagu gubi karaa heerkul kala duwan (qiyaastii 200 ° C ilaa 850 ° C) waxay heli karaan badeecooyin cufan oo cufan oo kala duwan leh (0.8 ~ 1.0g/cm3).
