Dab tsi yog qhov purity theem ntawm reworked magnesium oxide?

Reworked magnesium oxide feem ntau tuaj yeem ncav cuag Ntau dua lossis sib npaug li 99.9% purity yog tias nitrogen- tiv thaiv sintering thiab cov txheej txheem tswj kev ua qias tuaj yeem ua raws, thiab siab - purity raw cov ntaub ntawv (xws li, Ntau dua lossis sib npaug li 99.95%) yog siv. Cov khoom kawg yuav tsum muaj tsawg kawg yog 60% active magnesium oxide thiab tsawg kawg yog 95% MgO cov ntsiab lus (HG / T 3928-2012).

Cov ntsiab lus tseem ceeb cuam tshuam qhov kawg purity

Purity ntawm Raw Khoom|Siv cov hmoov magnesium oxide uas tsawg kawg yog 99.9% ntshiab (xws li, ua los ntawm Liaoning Jiashun Technology). Cov khoom xyaw nyoos nrog tsawg purity tam sim ntawd txo tag nrho qib.

Txheej Txheem Kev Tiv Thaiv Kab Mob|Kev ua haujlwm huv huv + kev tiv thaiv los ntawm siab -purity nitrogen (oxygen concentration<100 ppm). Moisture and contaminants are easily introduced when operating in an open environment.

Cov cuab yeej huv huv|Ua ntej siv cov khoom filling thiab sintering, ntxuav nws nrog siab -purity nitrogen. Localized txo nyob rau hauv purity yog tshwm sim los ntawm residual contamination.

Kev Tshawb Fawb|Tshuaj ntsuam xyuas (xws li acid-base titration) los ntawm ib tug thib peb- koom haum CNAS. Purity tsis tuaj yeem txiav txim siab los ntawm cov txheej txheem yooj yim.

Qhov ruaj khov MgO concentration ntawm ntau dua 95% tuaj yeem ua tiav raws li cov txheej txheem txheej txheem, txawm li cas los xij CNAS cov ntawv pov thawj yuav tsum tau kuaj xyuas qhov no.

Yuav Ua Li Cas Siab Purity Kom Zoo?

Qhov Chaw Tswj: Siv CNAS nkaus xwb- kuaj, siab- cov ntaub ntawv purity;

Txheej Txheem Kev Tiv Thaiv: Tag nrho kev kaw kom tsis txhob hla - paug thiab nqus dej noo;
