Zvivakwa uye Mashandisirwo eMagnesium Hydrooxide

Magnesium hydroxide (Mg(OH) ₂) ichena amorphous poda kana hexagonal crystal. Yakagadzikana mumakemikari uye ine yakanakisa yemuviri uye makemikari zvimiro, ichiratidza yakakosha kukosha kwekushandisa muakasiyana minda.

Pamuviri, magnesium hydroxide inoratidzira yakaderera density (inenge 2.36 g/cm³), yakakwira kunyungudika (kuora panosvika 350 degree), uye yakanakisa insulating zvivakwa. Chimiro chayo chekristaro chinowanzo kuve chakaturikidzana, chine hydrogen zvisungo pakati pematanho, zvichiita kuti ichengetedze kugadzikana kwechimiro kunyangwe pakupisa kwakanyanya. Uyezve, magnesium hydroxide ine nzvimbo yakakura yepamusoro, iyo inogona kukanganisa ayo adsorption maitiro uye reactivity.

Kemikari, magnesium hydroxide chigadziko chisina kusimba chine kunyungudika kwakanyanya kuderera (inenge 0.0002 mol/L pa25 degree). Naizvozvo, inoratidzira alkalinity yakapfava mumhinduro dzine aqueous, zvichiita kuti ive yakakodzera kune nharaunda inoda kushomeka kwekuora. Kunyange isinganyungudika mumvura, inonyungudika mumaasidhi kuumba inowirirana magnesium munyu nemvura. Ichi chivakwa chakonzera kushandiswa kwayo kwakapararira mukuchengetedza kwezvakatipoteredza se neutralizer kune acidic tsvina gasi uye tsvina. Uyezve, magnesium hydroxide ine tembiricha yekuwora yakakwira (inotanga paanenge 340 dhigirii kuzoora kuita magnesium oxide nemvura), uye maitiro ekuora ndeye endothermic, zvinobudirira kudzvanya kupisa. Naizvozvo, inowanzoshandiswa se inorganic flame retardant.

Magnesium hydroxide's low toxicity uye kushamwaridzana kwezvakatipoteredza kunoita kuti itsvakwe zvakanyanya mumaindasitiri emishonga, chikafu, uye epurasitiki. Semuenzaniso, mumunda wemishonga, inogona kushandiswa seantacid uye laxative; mumapurasitiki nemaindasitiri erabha, inogona kushandiswa senge inodzoreredza murazvo kuzadza moto kuvandudza kudzivirira kwemoto kwezvinhu pasina kukanganisa simba ravo remagetsi.

Muchidimbu, magnesium hydroxide, ine kugadzikana kwayo kwakanyanya, kuderera kwehuturu, uye kusimba kwemakemikari inertness, inobata tarisiro yakakosha yekushandisa mukureba kwemoto, kuchengetedza kwezvakatipoteredza, mushonga, uye sainzi yemidziyo. Nekufambira mberi kwetekinoroji, kukosha kwayo kunogona kuwongororwa zvakare.
