Sharaxaada
Magnesium oxide waa oksaydhka birta dhulka alkaline ee caadiga ah, qaacidada kiimikada MgO.Budada cad, barta dhalaalka 2852 ℃, barta karkarinta 3600 ℃, cufnaanta qaraabada ah ee 3.58 (25 ℃).Waxay ku milmi kartaa aashitada iyo milixda ammonium.Ficilkeeda qunyar socodka ah ee biyaha waxay soo saari kartaa magnesium hydroxide.Waxa lagu milmi karaa kaarboon laba ogsaydh oo dareere ah si loo soo saaro magnesium bicarbonate.Hawada, waxay si tartiib tartiib ah u nuugi kartaa qoyaanka iyo kaarboon dioxide.Kuleylku wuxuu sii daayaa qiiq xanaaq badan.Magnesite (MgCO3), dolomite (MgCO3 • CaCO3) iyo biyaha badda ayaa ah alaabta ceeriin ee ugu muhiimsan ee soo saarista magnesium oxide.
Magnesium oxide waxa loo qaybiyaa laba nooc oo ah magnesium oxide fudud iyo magnesium oxide culus.Birta magnesium oxide waa dabacsanaan mugga, budada amorphous cad.Aan ur lahayn, aan dhadhamin oo aan sun ahayn.Cufnaanta 3.58g/cm3.aan lagu milmin biyo saafi ah iyo dareere organic ah.Mugga magnesium oksaydh ee culus waa mid cufan, cad ama budo beige ah.oksaydhka magnesium-ka ee la horumariyay ayaa inta badan loo isticmaalaa saliidaha heerka sare, maqaar sare oo maqaar kor u qaadida darajada alkali, heerka cuntada, daawada, darajada birta silikoon, darajada sare ee electromagnetic, nadiifinta sare ee magnesium oxide iyo ku dhawaad toban nooc oo ka kooban.
Isticmaalka Magnesium oxide:
1, Mid ka mid ah isticmaalka ugu muhiimsan ee magnesium oxide waxaa loo isticmaalaa sidii ololka dib-u-kicinta, walxaha dab-damiska ee dhaqameed, polymers-ka kooban ee halogen-ka ah ee si ballaaran loo isticmaalo ama halogen-ka kooban ee dab-demiska oo lagu daray isku-darka dabka.
2, isticmaalka kale ee magnesium oxide waxaa loo isticmaali karaa sida wakiilka dhexdhexaad ah, magnesium oxide alkaline, waxqabadka adsorption wanaagsan, waxaa loo isticmaali karaa sida gaaska qashinka acid, daaweynta biyaha wasakhda ah, biraha culus iyo daaweynta qashinka organic iyo wakiilka kale ee dhexdhexaadinta, iyadoo shuruudaha deegaanka. Dalabka gudaha ayaa si degdeg ah u koraya.
3, cadaadiska magnesium oxide oo wanaagsan ayaa loo isticmaali karaa sida dahaarka indhaha.Dhumucda dahaarka inta u dhaxaysa 300nm iyo 7mm, daahan waa hufan.1mm dhumuc weyn oo daahan ah index refractive of 1.72.
4, loo isticmaalo fuulista isticmaalka dhagaxa, waxay nuugi kartaa dhididka gacanta, (Fiiro gaar ah: neefsashada qiiqa magnesium oxide waxay u horseedi kartaa cudurka qiiqa birta.)
5, inta badan loo isticmaalo diyaarinta wakiilada dawooyinka gudaha si looga takhaluso aashitada caloosha ee xad-dhaafka ah.Daawooyinka sida caadiga ah loo isticmaalo waa: caanaha magnesium - emulsion;Kiniinnada daboolka magnesium - qayb kasta waxay ka kooban tahay MgO0.1g,;Aashitada samaynta kala firdhiso - magnesium oxide iyo sodium bicarbonate oo lagu daray bulk, iwm.
6, oksaydhka magnesium khafiifka ah waxaa inta badan loo isticmaalaa sida walxo ceeriin ah oo loogu talagalay diyaarinta dhoobada, dhaldhalaalka, qolof-celinta iyo lebenka refractory.Waxa kale oo loo istcimaali jiray binder-ka abrasive iyo buuxinta warqadda, neoprene iyo dhiirigeliyaha caagga fluorine iyo firfircoonida
