Ndeupi musiyano uripo pakati pe magnesium oxide uye magnesium carbonate?

Magnesium oxideuyemagnesium carbonatezvakasiyana mumakemikari avo.Magnesium carbonateiasidhi isina simba inonyungudika mumvura uye inoputsika kuita magnesium oxide uye kabhoni dhaikisaidhi kana yapiswa.Magnesium oxide, kune rumwe rutivi, ialkaline oxide isinganyunguriki mumvura uye haiori kana yapiswa.

Indasitiri yekushandisa uye maitiro ezvigadzirwa zve magnesium carbonate uye magnesium oxide zvakasiyana sezvinotevera: Indasitiri yekushandisa: Magnesium carbonate inonyanya kushandiswa mumishonga yepakati, antacid, desiccant, mumiriri wekudzivirira mavara, mutakuri, anti-coagulation agent uye zvichingodaro;Muchikafu sechinhu chinowedzera, magnesium element compensation agent;Muindasitiri yemakemikari yakanaka yekugadzirwa kwemakemikari reagents;Inoshandiswa seanosimbisa agent uye filler mu rubber;Inogona kushandiswa sekudzivirira kupisa, kupisa kwakanyanya kusingadziviriri moto zvinhu;Waya netambo yekugadzira nzira yakakosha kemikari mbishi zvinhu, etc. Magnesium oxide inonyanya kushandiswa musilicon simbi, catalyst, indasitiri yemishonga, indasitiri yezvekudya, zvizorwa mbishi zvinhu, epurasitiki ekuwedzera, rabha additives, electrode zvinhu, girazi substrate zvinhu uye mamwe minda.Zvigadzirwa zvechigadzirwa: Magnesium carbonate ikristaro isina ruvara inopenya, alkaline, inonyungudika mumvura, zvishoma alkaline;Magnesium oxide, kune rumwe rutivi, ipfu chena, alkaline uye isinganyunguriki mumvura.

Magnesium carbonate yakakamurwa sezvinotevera:

Chiedza magnesium carbonate: chena brittle kana yakasununguka chena poda, isina kunhuhwirira, yakagadzikana mumhepo.Kana inopisa kusvika 700 ° C, inoora kuti ibudise magnesium oxide, carbon dioxide nemvura.Pakupisa kwekamuri, munyu une trihydrate.Heavy magnesium carbonate: hupfu huchena, husina kunaka, husinganyunguriki mumvura, inopisa kusvika kudarika 150 ℃ kuora, kugadzira magnesium oxide uye carbon dioxide.Pakupisa kwekamuri, iri hexahydrate munyu.

Kusarudzwa kwe magnesium oxide kunotevera:

Chiedza magnesium oxide: iyo molecular formula ndeye MgO, chitarisiko chichena kana beige mwenje poda, isinganhuhwi uye isinganakidze.Zvichiiswa mumhepo, zviri nyore kutora mvura necarbon dioxide, zvisinganyunguriki mumvura nedoro, uye zvinonyungudika mu dilute acids.Active magnesium oxide: inononoka kunyorera, inoshandiswa neoprene rubber kuzadza, kusimbisa uye secatalyst.Heavy magnesium oxide: Molecular formula MgO, kutaridzika kweupfu chena, isinganhuhwi, isinganyungudika mumvura.Kana ichipisa kupfuura 1500 ℃, inova yakafa yakatsva magnesium oxide (magnesia) kana sintered magnesium oxide.
