Magnesium Oxide Kev Kho Dej

Yuav ua li cas magnesium oxide dej kho: hmoov magnesium oxide reacts nrog dej los tsim magnesium hydroxide. Magnesium hydroxide tuaj yeem siv los ua ib qho nruab nrab rau cov kua qaub uas muaj cov pa khib nyiab, kev kho dej khib nyiab, kev kho cov hlau hnyav thiab cov kua dej khib nyiab, thiab lwm yam. Cov kua qaub hauv cov dej khib nyiab tuaj yeem ua rau nruab nrab, thiab nws tuaj yeem ua rau tsis zoo Cu, Fe, Cr ( 111), Pb, thiab Zn plasmas daim ntawv precipitates, uas raug tshem tawm ntxiv los ntawm lawv cov adsorption nyhuv kom ua tiav lub hom phiaj ntawm kev tshem tawm tag nrho.

Magnesium hydroxide muaj thaj tsam loj, muaj zog adsorption, thiab cov khoom solubility loj dua li cov hlau zoo tib yam. Hauv ntau yam, nws muaj cov txiaj ntsig zoo tshaj li cov tshuaj alkaline ib txwm muaj (xws li calcium hydroxide, sodium hydroxide, thiab lwm yam). Tsis tas li ntawd, hydrogen thiab magnesium oxide tuaj yeem rov ua dua tshiab hauv cov txheej txheem kho dej, uas tsis tsuas yog txuag nqi tab sis kuj txo qhov cuam tshuam rau ib puag ncig. Nyob rau hauv xyoo tas los no, magnesium oxide kev kho dej ua haujlwm tau siv dav hauv kev kho cov av paug los ntawm cov kua qaub los nag, kho cov pH nqi ntawm cov av, thiab neutralizing acidic khib nyiab.
