Magnesium Carbonate Description
Magnesium carbonate yog magnesium ntsev nrog mis CMgO3. Nws cov ntaub ntawv hydrated, tshwj xeeb tshaj yog cov di-, tri-, thiab tetrahydrates tshwm sim raws li cov zaub mov. Nws muaj lub luag haujlwm ua antacid thiab chiv. Nws yog magnesium ntsev, carbonate ntsev, ib qho carbon compound thiab organic magnesium ntsev.
Magnesium carbonate yog dej insoluble magnesium qhov chaw uas tau yooj yim hloov mus rau lwm cov magnesium tebchaw, xws li oxide los ntawm cua sov (calcination). Carbonate tebchaw kuj muab cov pa roj carbon dioxide thaum kho nrog dilute acids.
Qhov tseem ceeb ntawm magnesium carbonate yog kev tsim cov magnesium oxide los ntawm calcining. Magnesite thiab dolomite minerals yog siv los tsim refractory cib. MgCO3 kuj yog siv rau hauv pem teb, fireproofing, tua hluav taws muaj pes tsawg leeg, tshuaj pleev ib ce, plua plav hmoov, thiab tshuaj txhuam hniav. Lwm daim ntawv thov yog cov khoom siv muab tub lim, cov pa luam yeeb hauv cov yas, cov khoom siv ntxiv rau hauv cov roj hmab neoprene, tus neeg ua kom qhuav, thiab xim tuav hauv cov khoom noj.
Magnesium carbonate, feem ntau hu ua "chalk", kuj yog siv los ua tus neeg sawv cev ziab ntawm cov neeg ncaws pob tes hauv pob zeb nce toj, gymnastics, weightlifting thiab lwm yam kev ua si uas yuav tsum tau tuav ruaj khov.
Raws li cov khoom noj ntxiv, magnesium carbonate yog hu ua E504. Nws tsuas yog paub cov kev mob tshwm sim yog tias nws yuav ua hauj lwm raws li ib tug laxative nyob rau hauv siab concentrations.
Magnesium carbonate yog siv nyob rau hauv taxidermy rau whitening pob txha taub hau. Nws tuaj yeem tov nrog hydrogen peroxide los tsim cov tshuaj txhuam hniav, uas yog kis tau rau ntawm pob txha taub hau kom nws ua tiav dawb.
Magnesium carbonate yog siv los ua matte dawb txheej rau cov ntxaij vab tshaus projection.
Tsis tas li ntawd, siab purity magnesium carbonate yog siv los ua cov tshuaj tiv thaiv kab mob thiab ua ib qho ntxiv hauv cov lus ntsev kom nws ntws dawb. Magnesium carbonate tuaj yeem ua qhov no vim tias nws tsis yaj hauv dej, tsuas yog hauv cov kua qaub, qhov twg nws yuav effervesce ( npuas).
