Kufotokozera
Magnesium okusayidi ndi mmene zamchere lapansi zitsulo okusayidi, mankhwala chilinganizo MgO.White ufa, kusungunuka mfundo 2852 ℃, otentha mfundo 3600 ℃, kachulukidwe wachibale wa 3.58 (25 ℃).Imasungunuka mu mchere wa asidi ndi ammonium.Kuchita kwake pang'onopang'ono ndi madzi kumatha kupanga magnesium hydroxide.Ikhoza kusungunuka mu carbon dioxide amadzimadzi njira kupanga magnesium bicarbonate.Mumlengalenga, imatha kuyamwa pang'onopang'ono chinyezi ndi carbon dioxide.Kutentha kumatulutsa mpweya woipa.Magnesite (MgCO3), dolomite (MgCO3 • CaCO3) ndi madzi a m’nyanja ndi zinthu zazikulu zopangira magnesium oxide.
Magnesium okusayidi amagawidwa mu mitundu iwiri ya kuwala kwa magnesium oxide ndi heavy magnesium oxide.Magnesium okusayidi yowala ndi yosalala mu voliyumu, ufa woyera wa amorphous.Zopanda fungo, zosakoma komanso zopanda poizoni.Kachulukidwe 3.58g/cm3.osasungunuka m'madzi oyera ndi zosungunulira organic.Heavy magnesium oxide voliyumu ndi yaying'ono, yoyera kapena beige ufa.The otukuka bwino magnesium okusayidi zimagwiritsa ntchito mkulu kalasi lubricant, mkulu kalasi pofufuta chikopa kukweza alkali kalasi, chakudya kalasi, mankhwala, pakachitsulo zitsulo kalasi, mkulu kalasi electromagnetic kalasi, mkulu chiyero magnesium okusayidi ndi pafupifupi khumi mitundu zikuchokera.
Kugwiritsa ntchito Magnesium oxide:
1, imodzi mwazinthu zazikulu zomwe zimagwiritsidwa ntchito ndi magnesium oxide imagwiritsidwa ntchito ngati chotchingira moto, zida zamalawi zamalawi, zomwe zimagwiritsidwa ntchito kwambiri ndi ma polima okhala ndi halogen kapena zoziziritsa kumoto zokhala ndi halogen zophatikizidwira kusakaniza koletsa moto.
2, ntchito ina magnesium okusayidi angagwiritsidwe ntchito monga neutralizing wothandizila, magnesium okusayidi zamchere, zabwino adsorption ntchito, angagwiritsidwe ntchito ngati asidi zinyalala mpweya, mankhwala zinyalala, zitsulo zolemera ndi mankhwala zinyalala organic ndi wothandizila neutralizing, ndi zofunika zachilengedwe, zofuna zapakhomo zikukula mofulumira.
3, kupanikizika kwa magnesium oxide kungagwiritsidwe ntchito ngati zokutira zowala.Kupaka makulidwe pakati pa 300nm ndi 7mm, zokutira zimaonekera.1mm wandiweyani wokutira refractive index wa 1.72.
4, yomwe imagwiritsidwa ntchito pokwera miyala, imatha kuyamwa thukuta lamanja, (Zindikirani: kutulutsa utsi wa magnesium oxide kungayambitse matenda achitsulo.)
5, makamaka ntchito yokonza mkati mankhwala wothandizila neutralize owonjezera m`mimba asidi.Zomwe zimagwiritsidwa ntchito pokonzekera ndi: mkaka wa magnesium - emulsion;mapiritsi ophimba magnesiamu - chidutswa chilichonse chili ndi MgO0.1g ,;asidi kupanga kubalalitsa - magnesium okusayidi ndi sodium bicarbonate kusakaniza chochuluka, etc.
6, kuwala kwa magnesium oxide kumagwiritsidwa ntchito makamaka ngati zopangira pokonza zoumba, enamel, crucible refractory crucible and refractory njerwa.Amagwiritsidwanso ntchito ngati abrasive binder ndi paper filler, neoprene ndi fluorine mphira wolimbikitsa ndi activator.
