1)Gas theem carbonization
Cov tshuaj sodium carbonate yog carbonized los ntawm carbon dioxide nyob rau hauv lub carbonization ntauwd, thiab ces sib cais, qhuav thiab crushed, thiab cov khoom tiav lawm.
Na₂CO₃+CO₂(g) + H₂O→2 NaHCO₃
2)Gas solid theem carbonization
Cov sodium carbonate yog muab tso rau ntawm lub txaj cov tshuaj tiv thaiv, tov nrog dej, nqus pa carbon dioxide los ntawm qhov qis, qhuav thiab crushed tom qab carbonization, thiab cov khoom tiav lawm.
Na₂CO₃+CO₂+H₂O→2 NaHCO₃
1) Pharmaceutical kev lag luam
Sodium bicarbonate tuaj yeem siv ncaj qha los ua raw khoom hauv kev lag luam kws kho mob gastric acid overload; siv los ua raw khoom rau kev npaj acid.
2) Kev ua zaub mov
Hauv kev ua zaub mov, nws yog ib qho ntawm cov neeg siv ntau tshaj plaws loosening tus neeg saib xyuas, siv rau hauv kev tsim cov biscuits, qhob cij thiab lwm yam, yog cov pa roj carbon dioxide hauv dej qab zib; Nws tuaj yeem sib xyaw nrog alum rau alkaline ci hmoov, thiab tuaj yeem sib xyaw nrog cov dej qab zib soda rau pej xeem caustic soda. Nws kuj tseem siv tau ua butter preservative.
3) Cov khoom siv hluav taws xob
Siv hauv kev tsim cov kua qaub thiab alkali tua hluav taws thiab ua npuas dej tua hluav taws.
4) Kev lag luam roj hmab tuaj yeem siv rau roj hmab, daim txhuam cev ntau lawm;
5) Metallurgical kev lag luam tuaj yeem siv los ua cov dej ntws rau cov khoom siv hlau casting;
6) Kev lag luam tshuab siv tau los ua cov hlau cam (foundry) xuab zeb molding auxiliars;
7) Kev lag luam luam ntawv thiab dyeing tuaj yeem siv los ua cov xim luam ntawv kho tus neeg saib xyuas, kua qaub thiab alkali tsis, ntaub dyeing thiab xov ntawm tus neeg saib xyuas tom qab;
8) Kev Lag Luam Textile, ci dej qab zib ntxiv rau cov txheej txheem dyeing los tiv thaiv cov xov paj los ntawm kev tsim cov paj xim.

Kev ua kom tawg
Cais tawm qhov chaw paug tawm thiab txwv tsis pub nkag mus.Nws raug nquahu kom cov neeg ua haujlwm thaum muaj xwm txheej ceev hnav plua plav npog (npog npog) thiab hnav khaub ncaws ua haujlwm. Tsis txhob muaj plua plav, ua tib zoo cheb, muab tso rau hauv lub hnab thiab hloov mus rau qhov chaw nyab xeeb. Yog tias muaj cov dej xau ntau, npog nrog cov ntawv yas thiab cov canvas.Sau, rov ua dua lossis thauj mus rau qhov chaw pov tseg pov tseg.
Nco tseg cia
Sodium bicarbonate belongs rau cov khoom uas tsis muaj kev phom sij, tab sis yuav tsum tau tiv thaiv los ntawm dampness. Khaws rau hauv qhuav thiab ventilated storehouse.Nws tsis pub kom tov nrog acid. Baking soda yuav tsum tsis txhob tov nrog tshuaj lom kom tsis txhob muaj kuab paug.
