Magnesium carbonate tuaj yeem siv los ua cov ntaub ntawv refractory, cov ntaub ntawv khaws cia kub rau boilers thiab cov kav dej, nrog rau cov khoom siv ntxiv rau cov khoom noj, tshuaj, tshuaj pleev ib ce, roj hmab, number case, thiab lwm yam. Cov txheeb ze molecular loj ntawm magnesium carbonate yog 84.
xwm
Dawb monoclinic siv lead ua los yog amorphous hmoov. Tsis yog - lom, tsis muaj ntxhiab, ruaj khov hauv roj. Tus txheeb ze ntom ntom yog 2.16. Me ntsis soluble hauv dej, aqueous tov
Magnesium Carbonate
Nws yog qaug zog alkaline, thiab nws solubility hauv dej yog 0.02% (15 degree). Yooj yim soluble hauv acid thiab ammonium ntsev tov. Nws yog yooj yim decomposed rau hauv magnesium oxide thiab carbon dioxide thaum calcination. Nyob rau hauv cov ntaub ntawv ntawm dilute acid, carbon dioxide raug tso tawm. Feem ntau me ntsis soluble hauv dej. Thaum rhuab, nws yooj yim reacts nrog dej (thaum cov dej nyuaj softened) los tsim magnesium hydroxide (vim magnesium hydroxide yog insoluble ntau tshaj magnesium carbonate). Equation: MgCO3+H2O=Mg(OH)2+CO2
siv
Pharmaceutical intermediates, antacids, desiccants, xim tiv thaiv, cov cab kuj, los tiv thaiv -cov tshuaj tua kab mob; siv raws li additives nyob rau hauv cov khoom noj thiab magnesium them nyiaj
Tus neeg sawv cev; siv cov tshuaj zoo los tsim cov tshuaj reagents; siv los ua tus neeg saib xyuas thiab muab tub lim hauv roj hmab; siv los ua cua sov-insulating thiab siab-kub- tiv taus hluav taws- pov thawj thiab cua sov- khaws cia cov ntaub ntawv; tseem ceeb tshuaj raw cov ntaub ntawv nyob rau hauv lub manufacturing txheej txheem ntawm hlau thiab cables. Kev tsim khoom siab-kawg iav khoom; enamel ceramics ua lub luag haujlwm ntawm qhov ci ntsa iab; tsim magnesium ntsev, pigments, pleev xim, tshuaj pleev ib ce txhua hnub, nkoj tsim, thiab boiler manufacturing. Thiab rau cov neeg ncaws pob los so lawv txhais tes thaum sib tw.
Siv nyob rau hauv kev tsim cov magnesium ntsev, magnesium oxide, fireproof coatings, inks, iav, tshuaj txhuam hniav, roj hmab fillers, thiab lwm yam., siv raws li hmoov improvers, bread leavening agents, thiab lwm yam.
