Chaw tsim tshuaj paus zoo sodium bicarbonate CAS: 144-55-8
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.
