1, Tshuaj Lub Npe: Magnesium Carbonate
2, Molecular Formula: xMgCO3·yMg(OH) 2·zH2O
3, Molecular Luj: 485.65
CAS: 39409-82-0 Nr
5, Cim: Magnesium carbonate yog dawb, friable masses los yog unconsolidated dawb odorless hmoov. melting point yog 350 degree. Nws ruaj khov hauv huab cua. Thaum rhuab mus rau 700 degree, nws decomposes carbon dioxide thiab magnesium oxide. Nws yuav luag insoluble hauv dej, tab sis nws imparts me ntsis alkaline cov tshuaj tiv thaiv. Nws yog insoluble hauv ethanol, tab sis dissolves nyob rau hauv dilute acids nrog effervescence.
6, Kev Siv: Nws tuaj yeem siv los ua cov khoom noj khoom haus, tshuaj kho hmoov nplej, tshuaj tiv thaiv - tus neeg sawv cev ua kua thiab cov hmoov nplej. Nws kuj tuaj yeem siv rau hauv cov hmoov nplej thiab cov pos hniav.
7, Ntim: Nws tau ntim nrog lub hnab polyethylene ua txheej txheej sab hauv, thiab lub hnab yas sib xyaw ua ke raws li txheej txheej. Qhov hnyav ntawm txhua lub hnab yog 25kg.
8, Cia thiab Thauj Khoom: Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav thiab qhov cua, khaws cia kom deb ntawm tshav kub thiab ya raws thaum thauj, tshem tawm nrog kev saib xyuas kom tsis txhob muaj kev puas tsuaj. Tsis tas li ntawd, nws yuav tsum tau muab cais tawm ntawm cov tshuaj lom.
