Magnesium sulfate feem ntau yog xim dawb, tab sis qee zaum vim kev hloov pauv tshuaj nws yuav ua rau discoloration.there muaj ntau yam laj thawj rau qhov raug tshem tawm, xws li Ntuj ib puag ncig, tib neeg yam thiab lwm yam. Cov ntsiab lus muaj raws li hauv qab no:
1. Magnesium sulphate yog yooj yim soluble hauv dej thiab muaj kev ua si muaj zog. Ntxiv hlau ntawm cov xim sib txawv, lwm yam xim tau pom tseeb txhim kho, thiab cov xim hloov tau hloov.
2. Ua raws li cov yam ntxwv ntawm cov hlau hnyav, qhov rhiab ntawm magnesium sulphate kuj tseem muaj sib txawv.
3. Thaum lub sijhawm npaj cov txheej txheem, lub cev loj yog ua haujlwm los ntawm cov tshuaj tiv thaiv ion thiab oxidation. Yog tias cov ntsiab lus hlau hnyav tau infiltrated, vim tias lawv yog cov tsis muaj zog ions, txoj kab ntawm ntxaij hlau deforms thiab poob qhov zoo ib yam, pom cov nyhuv.
4. Feem ntau, cov tshuaj magnesium sulfate yog dawb, thiab nws yog qhov cuam tshuam los cuam tshuam nrog lwm cov tshuaj hauv daim ntawv thov. Cov xim ntawm cov hlau hnyav yog qhov hnyav, thiab cov pleev kom pom ntawm tus duab tseem ceeb. Piv txwv li, chromium, manganese, hlau, tooj liab, laum khoom, cerium, vanadium, txhuas thiab lwm cov hlau hnyav ua rau tsis zoo. Txawm hais tias ib qho nyiaj tsawg me me tuaj yeem ua rau pom kev zoo ntawm cov xim hlau.
5. Magnesium sulphate heptahydrate nrog sib ntxiv sib txawv ntau thiab cov yam ntxwv ntawm cov hlau hnyav muaj xim sib txawv. Lub rutile hom yog nkag siab zoo rau cawv ntawm impurities. Thaum cov ntsiab lus ntawm rutile hom hlau oxide ntau dua 0,003%, ib qho xim tau tshwm sim, thiab thaum cov ntsiab lus ntawm hom anatase ntau dua 0,009%, muaj xim tshwm sim.
