Xabagta Magnesium: Guryaha, Diyaarinta, codsiga

xabagta Magnesium waxaa badanaa loo magnesia dheeraad ah si fudud la gubo ama xabagta magnesium. Qoraalkan waa miisaanka yar oo ganaax ah budada cad crystalline. In dabiiciga ah, xabagta magnesium ku dhacdaa sida periclase macdanta. warshadaha cuntada waa maaddo loo yaqaan daro cuntada hoos E530 code.

Sifooyinka xabagta magnesium

Formula Chemical oo ah walaxda: MgO. Xarunta waxa uu leeyahay ku dhowaad aan ur lahayn ammonia iyo acid waa diyaar L. biyo, ay milmi at 30 ° C waa grams oo kaliya 0.0086 / 100 ml, iyo khamri ah iyo waxa aanu u milmaan. mass gaws ee MgO - 40,3044 g / mol. At 20 ° C iyo cufnaanta waa 3.58 g / cm³, heerkulka kulul - 3600 ° C, barafka - 2852 ° C. xabagta magnesium Melkokristallichesky kiimikaad ahaan waa wax firfircoon. Waa awood u aadeen carbon dioxide si ay u sameeyaan carbonate u dhigma:

• MgO + CO ₂ = MgCO _3;

inkastoo si tartiib tartiib ah, laakiin weli sameynayso biyo, la xirrira beelaya saldhig daciif ah :

• H ₂ O + MgO = mg (OH) _2;

waxaa ka jawaabay acid ah:

• 2HCl + MgO = MgCl ₂ + H ₂ O

The xabagta magnesium calcined lumiyo falcelin. Waa in sidoo kale lagu daray in gigroskopechen budada this.

Diyaarinta xabagta magnesium

In warshadaha, xarunta this waxaa muhiimad diyaariyey toogasho. The alaabta ceeriin loo isticmaalo macdanta sida dolomite (MgCO3.CaCO3) ama magnesia (MgCO3). Intaa waxaa dheer, magnesia waxaa lagu fuliyaa iyadoo la isticmaalayo bishofit calcination ah (MgCl ₂ x 6 saac ₂ O) ee uumiga biyaha, calcining mg (OH) 2 iyo kale deganayn si heer kulka xeryahooda mg. Under xaaladaha shaybaarka, MgO in loo diyaar garoobo laga yaabaa in ay dareen-celin ka mid ah qaybaha ay dastuurka:

• 2Mg + O ₂ = 2MgO;

ama by kala daatay kaamerada ee cusbada ama hydroxide:

• MgCO ₃ = MgO + CO _2.

Iyada oo ku xidhan habka wax soo saarka ee xabagta magnesium waa caado ah in la kala saaro laba nooc oo waaweyn oo xeryahooda: iftiin iyo magnesia culus. Ka hore waa budo midab, taas oo waa wax fudud oo ku filan si ay u galaan falcelinta kala duwan la acids milo, dheehan mg cusbada loo sameeyay. labaad wuxuu ka kooban yahay kiristaalo badan oo periclase dabiici ah ama aan dabiici ahayn oo iska caabin ah biyo distinguished iyo waa ka inert.

xabagta magnesium

In warshadaha, xarunta waxa loogu adeegsaday saarta cement, madax adkaadeen, sida filler in caag oo loogu daweeyo saliid macdanta. xabagta magnesium Ultralight waxaa loo isticmaalaa sida aad u wanaagsan sugi lahaayeen oo daahirisay dusha,. Gaar ahaan, waxaa loo isticmaalaa in industry ee korantada. Intaa waxaa dheer, magnesia waxaa si balaadhan looga isticmaalaa in daawada. Halkee MgO waxaa loo isticmaalaa in xad gudub ku ah heerka aysidhka gastric dhaca sabab u ah xad-dhaaf ah ee Aashito. xabagta Magnesium sidoo kale u qaada neutralizing walxaha firfircoon si kama qabto caloosha. In warshadaha cuntada MgO waxaa loo isticmaalaa sida daro cuntada (E530) code a, taasoo ka hortagaysa clumping iyo caking. Magnesia sidoo kale loo isticmaalaa in jimicsi. Halkan, budada ah waxaa laga codsadaa in ay gacanta u fudud inaad la xiriirto qalabka jimicsiga ka kalsoonaan karo. Ku dar xabagta magnesium in uu yahay iftiinta sixun. Wehliyaha The milicsiga oo ah walaxda in band ballaaran spectral waa loo siman yahay si midnimo iyo sidaas darteed waxaa laga yaabaa in si fiican loo isticmaalo tixraac cad.
