Sodium Sulphate Decahydrate CAS 7727-73-3
Sodium sulfate decahydrate (Glauber's ntsev, mirabilite, Na2SO4 · 10H2O) yog decahydrate ntsev ntawm sodium sulfate. Nws cov qauv siv lead ua tau raug tshawb xyuas los ntawm ib leeg-crystal neutron diffraction kev tshawb fawb. Nws cov crystallization enthalpy tau soj ntsuam. Nws tuaj yeem ua ke los ntawm reacting MnSO4, thiophene-2,5-dicarboxylic acid thiab sodium glutamate.

1 Kev kho dej:
Sodium sulfate decahydrate tuaj yeem siv rau hauv cov txheej txheem kho dej, tshwj xeeb tshaj yog tshem cov hlau ions thiab lwm yam impurities los ntawm dej. Nws tuaj yeem ua haujlwm zoo nrog cov hlau ions los tsim cov dej tsis sib haum.
2 Detergents thiab ntxuav hmoov:
Hauv cov tshuaj ntxuav tes thiab ntxuav cov hmoov, sodium sulfate decahydrate yog siv los ua tus neeg sawv cev pabcuam los pab txhim kho cov nyhuv tu. Nws tuaj yeem siv los ua dej hardness regulator hauv detergents los tiv thaiv cov ntxhia hauv dej los ntawm kev cuam tshuam rau kev ntxuav.
3 Papermaking kev lag luam:
Hauv cov txheej txheem papermaking, nws tuaj yeem siv los ua qhov nruab nrab lossis cov khoom ntxiv los kho cov pH ntawm cov ntaub so ntswg thiab txhim kho cov ntawv zoo.
4 Glassmaking: Hauv cov txheej txheem iav ntau lawm, sodium sulfate decahydrate tuaj yeem siv los ua cov dej ntws los pab txo cov ntsiab lus melting thiab txhim kho cov melting efficiency.
5 Desiccant: Qee zaum, sodium sulfate decahydrate kuj tuaj yeem siv los ua cov desiccant nrog hygroscopicity muaj zog thiab siv rau ziab hauv chav kuaj lossis kev lag luam.
