Magnesium oxide
Mbiri yamalonda
Magnesium okusayidi, ndi inorganic pawiri, mankhwala chilinganizo MgO, ndi okusayidi wa magnesium, ndi ionic pawiri, woyera olimba kutentha firiji. Magnesium oxide ilipo mwachilengedwe mu mawonekedwe a magnesite ndipo ndi zinthu zopangira kusungunula kwa magnesium.
Magnesium oxide imakhala ndi kukana moto kwambiri komanso kutsekereza katundu. Pambuyo kutentha kutentha pamwamba pa 1000 ℃ akhoza kusinthidwa kukhala makhiristo, kukwera kwa 1500-2000 °C kukhala akufa kuwotchedwa magnesium oxide (magnesia) kapena sintered magnesium oxide.

Malo ogwiritsira ntchito:
Ndiko kutsimikiza kwa sulfure ndi pyrite mu malasha ndi sulfure ndi arsenic muzitsulo. Ntchito ngati muyezo woyera inki. Magnesium okusayidi yowala imagwiritsidwa ntchito makamaka ngati zopangira pokonza zoumba, ma enamel, crucible refractory ndi njerwa zowumitsa. Amagwiritsidwanso ntchito ngati zomatira, zokutira, ndi zojambulira mapepala, neoprene ndi fluorine rabara accelerators ndi activator. Pambuyo kusakaniza ndi magnesium chloride ndi njira zina, magnesium oxide madzi akhoza kukonzekera. Amagwiritsidwa ntchito pazamankhwala ngati antacid ndi mankhwala ofewetsa tuvi tolimba kwa chapamimba asidi owonjezera ndi duodenal chilonda matenda. Ntchito mu makampani mankhwala monga chothandizira ndi zopangira kupanga magnesium mchere. Amagwiritsidwanso ntchito popanga magalasi, chakudya chopaka utoto, mapulasitiki a phenolic, etc. Heavy magnesium oxide imagwiritsidwa ntchito pamakampani opanga mpunga powombera mphero ndi theka la odzigudubuza. Makampani omanga opangira makina opangira mapulasitiki opangira mapulasitiki opangidwa ndi mapulasitiki omwe amagwiritsidwa ntchito ngati zodzaza. Itha kugwiritsidwanso ntchito kupanga mchere wina wa magnesium.
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi magnesium oxide ndikugwiritsa ntchito zoletsa malawi, zida zachikhalidwe zoletsa malawi, ma polima okhala ndi halogen kapena ma halogen okhala ndi flame retardants kuphatikiza kusakaniza koletsa moto. Komabe, moto ukangochitika, chifukwa cha kuwonongeka kwamafuta ndi kuyaka, umatulutsa utsi wambiri komanso mpweya wowopsa, womwe ungalepheretse kulimbana ndi moto ndi kuthamangitsidwa kwa ogwira ntchito, kuwononga zida ndi zida. Makamaka, zapezeka kuti oposa 80% ya imfa pa moto chifukwa cha utsi ndi mpweya poizoni opangidwa ndi zinthu, kotero kuwonjezera lawi retardant dzuwa, utsi otsika ndi otsika kawopsedwe ndi zizindikiro zofunika kwambiri. zoletsa moto. Kukula kwamakampani oletsa malawi aku China ndikosalinganizika kwambiri, ndipo kuchuluka kwa zoletsa moto za chlorine ndizolemetsa, zomwe ndizoyamba mwazoletsa moto, zomwe parafini wa chlorinated amakhala ndi udindo wolamulira. Komabe, chlorine flame retardants imatulutsa mpweya wapoizoni pamene ichita, zomwe ziri kutali ndi kufunafuna kosaopsa komanso kothandiza kwa moyo wamakono. Choncho, kuti tigwirizane ndi chitukuko cha utsi wochepa, kawopsedwe wochepa komanso zoletsa moto padziko lonse lapansi, kutukuka, kupanga ndi kugwiritsira ntchito magnesium oxide retardants ndikofunika.
