Kev piav qhia
Magnesium oxide yog ib qho alkaline ntiaj teb hlau oxide, tshuaj formula MgO.Dawb hmoov, melting point 2852 ℃, boiling point 3600 ℃, tus txheeb ze ceev ntawm 3.58 (25 ℃).Nws yog soluble hauv acid thiab ammonium ntsev tov.Nws ua haujlwm qeeb nrog dej tuaj yeem tsim magnesium hydroxide.Nws tuaj yeem yaj hauv carbon dioxide aqueous tov los tsim magnesium bicarbonate.Nyob rau hauv cov huab cua, nws yuav maj mam nqus noo noo thiab carbon dioxide.Cov cua kub tso tawm cov pa taws.Magnesite (MgCO3), dolomite (MgCO3 • CaCO3) thiab dej hiav txwv yog cov khoom siv tseem ceeb rau kev tsim cov magnesium oxide.
Magnesium oxide muab faib ua ob hom teeb magnesium oxide thiab hnyav magnesium oxide.Lub teeb magnesium oxide yog lax hauv ntim, dawb amorphous hmoov.Tsis muaj ntxhiab, tasteless thiab tsis muaj tshuaj lom.Qhov ceev 3.58g / cm3.insoluble hauv dej ntshiab thiab organic hnyav.Hnyav magnesium oxide ntim yog compact, dawb los yog beige hmoov.Cov tsim zoo magnesium oxide yog tsuas yog siv rau qib siab lubricant, qib siab tanning tawv lifting alkali qib, zaub mov qib, tshuaj, silicon steel qib, qib high electromagnetic qib, siab purity magnesium oxide thiab ze li kaum ntau yam ntawm muaj pes tsawg leeg.
Kev siv magnesium oxide:
1, ib qho ntawm cov khoom siv tseem ceeb ntawm magnesium oxide yog siv los ua cov nplaim hluav taws xob, cov khoom siv hluav taws xob ib txwm siv, dav siv halogen-muaj polymers lossis halogen-muaj cov nplaim hluav taws sib xyaw ua ke rau hauv cov nplaim hluav taws sib xyaw.
2, lwm yam kev siv magnesium oxide tuaj yeem siv los ua tus neeg sawv cev nruab nrab, magnesium oxide alkaline, kev ua haujlwm zoo adsorption, tuaj yeem siv los ua kua qaub pov tseg, kev kho dej khib nyiab, cov hlau hnyav thiab cov khoom siv pov tseg thiab lwm yam kev ua haujlwm tsis zoo, nrog rau ib puag ncig, qhov kev thov hauv tsev tau loj hlob sai.
3, lub siab ntawm nplua magnesium oxide tuaj yeem siv los ua cov txheej txheem kho qhov muag.Txheej thickness ntawm 300nm thiab 7mm, lub txheej yog pob tshab.1 hli tuab txheej refractive index ntawm 1.72.
4, siv rau kev siv pob zeb nce toj, tuaj yeem nqus tau tes tawm hws, (Ceeb toom: nqus pa ntawm magnesium oxide tuaj yeem ua rau cov kab mob smog hlau.)
5, feem ntau yog siv rau kev npaj cov tshuaj sab hauv cov neeg ua haujlwm kom tsis txhob muaj cov kua qaub ntau dhau.Kev npaj siv ntau yog: magnesium mis nyuj - emulsion;magnesium npog ntsiav tshuaj - txhua daim muaj MgO0.1g,;acid ua tawg - magnesium oxide thiab sodium bicarbonate sib xyaw rau hauv ntau, thiab lwm yam.
6, lub teeb magnesium oxide feem ntau yog siv los ua raw khoom rau kev npaj ntawm ceramics, enamel, refractory crucible thiab refractory cib.Kuj tseem siv los ua abrasive binder thiab ntawv muab tub lim, neoprene thiab fluorine roj hmab txhawb nqa thiab activator
