Puas muaj ib txoj hauv kev yooj yim rau kev ntsuas qhov purity ntawm magnesium oxide

Kev tshuaj xyuas ua ntej tuaj yeem ua tiav siv cov tsos, qhov ntom ntom, thiab X-ray, tab sis tsis muaj cov txheej txheem ncaj qha uas tuaj yeem hloov kho cov kws tshaj lij. Ib tug thib peb - tog, CNAS- tau lees paub lub koom haum tshuaj tshuaj ntsuam xyuas yuav tsum tau ua kom paub tseeb qhov purity ntawm magnesium oxide. Tsuas yog qhov txawv txav tsis zoo raug txiav tawm siv cov txheej txheem hauv qab no.

1. Kev tshuaj xyuas qhov muag (Kev kuaj thawj zaug sai)

Txais Cov Nta: Cov hmoov tsis muaj grey-dub lossis daj- xim av thiab yog dawb, zoo, thiab pob - dawb;

Cov tsos mob txawv txav: Cov hmoov yuav tau nqus dej los yog muaj cov impurities xws li Fe2O3 lossis CaO yog tias nws muaj xim tsaus, pob, lossis cov khoom txawv teb chaws.

Cl⁻ thiab SO₄2⁻ yog cov piv txwv ntawm cov kab tsis huv uas tsis tuaj yeem txheeb xyuas los ntawm cov xim thiab tseem xav tau kev kuaj ntxiv.

2. Ua kom tiav qhov Kev Txiav Txim Siab Tsis Ncaj Ncees

Txoj kev: Siv tus qauv kawm tiav lub tog raj kheej, txiav txim siab qhov loj ntawm cov hmoov hauv ib chav tsev ntim;

2.8-3.2 g / cm³ yog qhov siv tau;

Kev txawv txav: Cov ntsiab lus siab impurity, coarse hais, lossis siab porosity coj los ntawm noo noo nqus tuaj yeem ua rau muaj qhov ntom ntom.

Txawm hais tias nws tsis tuaj yeem cuam tshuam cov tshuaj purity, qhov no tuaj yeem pab txiav txim siab homogeneity ntawm raw cov ntaub ntawv.

3. Kev tshuaj xyuas tus qauv ntawm X-ray Inspection

Cov Ntsiab Tshuaj Ntsuam Xyuas Tseem Ceeb: Txawm hais tias lub raj ntim puv muaj qhov khoob, tawm -cov cores, lossis qhov ntom ntom tsis sib xws;

Ntau dua lossis sib npaug li 5μm yog qhov yuav tsum tau daws teeb meem.

Lub hauv paus rau Kev Txiav Txim: Ib qho qauv tsis sib xws tuaj yeem yog ib qho kev qhia ntawm cov khoom siv raw tsis sib xws los yog cov kab mob sib kis uas cuam tshuam rau kev ntws.

Kev sim tshuaj chemical tseem yuav tsum tau siv ua ke nrog qhov tsis yog -kev pabcuam kev puas tsuaj hauv cov txheej txheem tsim khoom.

Yam tseem ceeb uas yuav tsum tau muaj rau kev sim

Kev lees txais cov khoom kuaj cov khoom Standard Test Procedure

MgO Cov Ntsiab Lus Ntau dua lossis sib npaug rau 95% Acid-piv Titration Technique

Txoj kev Active Magnesium Oxide Ntau dua lossis sib npaug li 60% Hydration

Txoj kev pom thiab qhov hnyav Hydrochloric Acid Insoluble Matter Tsawg dua lossis sib npaug li 0.5%

Cl⁻, SO₄²⁻ Tsawg dua lossis sib npaug li 0.02% / Tsawg dua lossis sib npaug rau 0.1% Titration lossis turbidimetric txheej txheem
