Yuav ua li cas tsim Magnesium Sulfate Heptahydrate ntawm Sulfuric acid txheej txheem?
Cov khoom siv raw: Magnesium oxide lossis magnesium hydroxide los yog magnesium carbonate thiab sulfuric acid.
Cov tshuaj tiv thaiv mis:
MgO + H2SO4 + 6H2O = MgSO4.7H2O
Ua piv txwv li Magnesium Oxide:
1. Ntsuas cov calcium oxide ore thiab sulfuric acid sib npaug.
2. Ntxiv qee qhov dej hauv nruab nrab lub taub dej, maj mam ntxiv cov hlau oxide thiab Ua kom nws , Tom qab ntawd ntxiv sulfuric acid thiab ua kom PH = 5, Ntom = 1.370g / m ³ - 1.384g / m ³ , Qhov kub = 80 ℃ .
3. Lim cov dej sib xyaw thiab muab tso rau hauv cov crystallizer.
4. Txias rau 30 ℃ thiab raug rau centrifugal sib cais.
5. Muab cov khoom ntub ntub tso rau hauv lub txaj fluidized txaj.
6. Qhuav nws thiab tau txais Magnesium Sulfate Heptahydrate ntawm 50 ℃ -55 ℃
