I-Magnesium oxide
Iprofayile yemveliso
I-Magnesium oxide, i-inorganic compound, i-chemical formula MgO, i-oxide ye-magnesium, i-ionic compound, emhlophe eqinile kwiqondo lokushisa. I-Magnesium oxide ikhona kwindalo ngohlobo lwe-magnesite kwaye yimathiriyeli ekrwada yokunyibilikiswa kwe-magnesium.
I-Magnesium oxide inokumelana nomlilo ophezulu kunye neempawu zokugquma. Emva kokutshisa okuphezulu kobushushu obungaphezulu kwe-1000℃ inokuguqulwa ibe ziikristale, inyuke iye kwi-1500-2000 °C ibe yi-magnesium oxide efileyo etshileyo (i-magnesia) okanye i-magnesium oxide ediyiweyo.
Isalathiso soBugcisa
Indawo yosetyenziso:
Kukumiselwa kwesulfure kunye nepyrite kumalahle kunye nesulfure kunye ne-arsenic kwintsimbi. Isetyenziswa njengomgangatho webala elimhlophe. I-magnesium oxide ekhanyayo isetyenziswa kakhulu njengezinto eziluhlaza zokulungiswa kweekeramics, i-enamels, i-crucible refractory kunye nezitena eziphikisayo. Ikwasetyenziswa njengezinto zokuncamathelisa ze-ejenti yokupolisha, ii-coatings, kunye nezihluzi zephepha, i-neoprene kunye ne-fluorine accelerators yerabha kunye ne-activators. Emva kokudibanisa ne-magnesium chloride kunye nezinye izisombululo, amanzi e-magnesium oxide anokulungiswa. Isetyenziselwa amayeza njenge-antacid kunye ne-laxative yokugqithisa kwe-asidi yesisu kunye nesifo se-duodenal ulcer. Isetyenziswa kushishino lweekhemikhali njenge-catalyst kunye nemathiriyeli ekrwada ekwenzeni iityuwa ze-magnesium. Ikwasetyenziselwa ukuveliswa kweglasi, ukutya okudayiweyo, iiplastiki zephenolic, njl njl. I-magnesium oxide enzima isetyenziswa kwishishini lokugaya irayisi yokudubula kunye ne-half rollers. Ushishino lolwakhiwo lokwenziwa kweekhemikhali zomgangatho owenziweyo webhastile lofakelo lwebhodi yokufakelwa kwesandi ibhodi yeplastiki esetyenziswa njengesizaliso. Ingasetyenziselwa ukuvelisa ezinye iityuwa ze-magnesium.
Olunye lolona setyenziso luphambili lwe-magnesium oxide kukusetyenziswa kwezixhobo zokulinda amadangatye, izixhobo zendabuko ezinqanda idangatye, iipolymers ezinehalogen ezisetyenziswa ngokubanzi okanye i-halogen equlathe i-flame retardants indibaniselwano ye-flame retardant mix. Nangona kunjalo, xa umlilo usenzeka, ngenxa yokubola kwe-thermal kunye nokutsha, kuya kuvelisa umsi omkhulu kunye neegesi ezinobuthi ezinobuthi, eziya kuthintela ukulwa nomlilo kunye nokukhutshwa kwabasebenzi, ukubola kwezixhobo kunye nezixhobo. Ngokukodwa, kuye kwafunyaniswa ukuba ngaphezu kwe-80% yokufa emlilweni kubangelwa ngumsi kunye neegesi ezinobuthi eziveliswa yizinto eziphathekayo, ngoko ke ukongeza kwi-retardant ye-flame retardant, umsi ophantsi kunye ne-toxicity ephantsi nazo zizibonakaliso ezibalulekileyo. iiretadants zomlilo. Uphuhliso lweshishini laseTshayina elibuyisela idangatye alilungelelananga ngokugqithisileyo, kwaye umlinganiselo wezinto ezibuyiswa ngamadangatye eklorini unzima noko, ongowokuqala kuzo zonke iiretardants zedangatye, apho iparafini eneklorini ikwimo yoyedwa. Nangona kunjalo, i-chlorine flame retardants ikhupha iigesi ezinetyhefu xa zisenza, ezikude ne-non-toxic kunye nokusukela ngokufanelekileyo ubomi banamhlanje. Ke ngoko, ukuze kuthotyelwe indlela yophuhliso lomsi ophantsi, ubuthi obuphantsi kunye nezithinteli zomlilo ezingangcolisekiyo emhlabeni, uphuhliso, ukuveliswa kunye nokusetyenziswa kwe-magnesium oxide retardants yomlilo iyimfuneko.
