Txoj cai ntawm kev tsim cov anhydrous sodium sulfates

Kev tsim cov txheej txheem ntawm anhydrous sodium sulfates yog ua nyob rau hauv ob txoj kev: thermal thiab tshuaj.
Cov txheej txheem thermal suav nrog cua sov sodium sulfate hydrate rau qhov kub thiab txias, feem ntau tshaj 300 degrees, kom tshem tawm cov dej molecules. Cov txheej txheem yuav siv sij hawm qhov chaw nyob rau hauv ib tug smelter los yog teb kiln qhov twg sodium sulfate hydrates qhuav thiab ces rhuab mus rau high kub. Cov dej ces evaporates, tawm hauv crystalline khoom anhydrous sodium sulfate.
Ntawm qhov tod tes, cov txheej txheem tshuaj cuam tshuam nrog kev ua haujlwm ntawm sodium sulfate nrog cov kua qaub (xws li concentrated sulfuric acid). Cov tshuaj tiv thaiv tsim sodium sulfate thiab dej thiab ces rhuab los tsim anhydrous sodium sulfate.
Ob txoj kev muaj lawv qhov zoo thiab qhov tsis zoo. Cov txheej txheem thermal yog qhov yooj yim thiab ncaj ncees, tab sis yuav tsum muaj qhov kub thiab txias thiab ua haujlwm ntev dua. Ntawm qhov tod tes, cov txheej txheem tshuaj yuav tsum tau siv cov kua qaub uas muaj zog thiab ua tib zoo tuav, tab sis ua haujlwm zoo dua thiab siv sijhawm ntev dua.
Dhau li ntawm txoj kev tsim khoom, lwm yam xws li cov khoom siv raw purity, cov tshuaj tiv thaiv thiab cov txheej txheem ua haujlwm kuj cuam tshuam rau qhov zoo ntawm cov khoom kawg.
