Magnesium oxide
Boemo ba sehlahisoa
Magnesium oxide, ke motsoako oa inorganic, formula ea lik'hemik'hale MgO, ke oxide ea magnesium, ke motsoako oa ionic, o tiileng o mosoeu mocheso oa kamore. Magnesium oxide e teng ka tlhaho ka sebopeho sa magnesite mme ke thepa e tala bakeng sa ho qhibilihisa magnesium.
Magnesium oxide e na le matla a phahameng a ho hanyetsa mollo le thepa ea ho kenya letsoho. Kamora mocheso o phahameng o tukang kaholimo ho 1000 ℃ o ka fetoloa likristale, o nyolohela ho 1500-2000 °C ho magnesium oxide e chesitsoeng (magnesia) kapa sintered magnesium oxide.

Ke boikemisetso ba sebabole le pyrite ka mashala le sebabole le arsenic ka tšepe. E sebelisoa e le tekanyetso ea li-pigments tse tšoeu. Magnesium oxide e sebelisoa haholo-holo e le lisebelisoa tse tala bakeng sa ho lokisa lirafshoa, li-enamel, li-crucible crucible le litene tse refractory. E boetse e sebelisoa e le li-adhesives, li-coatings, le li-filler tsa pampiri, li-accelerator tsa rabara tsa neoprene le fluorine le li-activator. Kamora ho kopanya le magnesium chloride le litharollo tse ling, metsi a magnesium oxide a ka lokisoa. E sebelisoa meriana e le antacid le laxative bakeng sa gastric acid feteletseng le lefu la duodenal ulcer. E sebelisoa indastering ea lik'hemik'hale e le mohloli le lisebelisoa tse tala bakeng sa tlhahiso ea letsoai la magnesium. E boetse e sebelisoa ha ho etsoa likhalase, lijo tse dailoeng, li-plastiki tsa phenolic, joalo-joalo Heavy magnesium oxide e sebelisoa indastering ea ho sila raese bakeng sa ho thunya le li-roller halofo. Indasteri ea kaho bakeng sa ho etsa boto ea maiketsetso ea lik'hemik'hale fatše ea maiketsetso ea 'mabole e futhumatsang molumo oa boto ea polasetiki e sebelisoang e le filler. E ka boela ea sebelisoa ho hlahisa matsoai a mang a magnesium.
E 'ngoe ea litšebeliso tsa mantlha tsa magnesium oxide ke ts'ebeliso ea li-retardants tsa lelakabe, lisebelisoa tsa setso tse thibelang lelakabe, lipolima tse sebelisoang haholo tse nang le halogen kapa li-halogen tse nang le lelakabe le kopaneng la motsoako o thibelang lelakabe. Leha ho le joalo, hang ha mollo o hlaha, ka lebaka la ho bola le ho tuka ha mocheso, o tla hlahisa mosi o mongata le likhase tse chefo tse senyang, tse tla sitisa ho loantša mollo le ho tlosoa ha basebetsi, ho bola ha lisebelisoa le lisebelisoa. Ka ho khetheha, ho fumanoe hore batho ba fetang 80% ba shoang mollong ba bakoa ke mosi le likhase tse chefo tse hlahisoang ke lintho tse bonahalang, kahoo ho phaella ho ts'ebetso ea ho thibela lelakabe, mosi o tlaase le chefo e tlaase e boetse e le matšoao a bohlokoa a tse thibelang malakabe. Tsoelo-pele ea indasteri e thibelang malakabe ea Chaena ha e leka-lekane haholo, 'me karolo ea li-retardants tsa chlorine e batla e le boima, e leng eona ea pele ho tse thibelang malakabe, tseo parafine ea chlorine e leng eona feela. Leha ho le joalo, li-retardants tsa chlorine flame li lokolla likhase tse chefo ha li sebetsa, e leng hole le ho se be chefo le ho lelekisa bophelo ba sejoale-joale. Ka hona, e le ho ipapisa le mokhoa oa nts'etsopele ea mosi o tlase, chefo e tlase le li-retardants tse se nang tšilafalo lefatšeng, nts'etsopele, tlhahiso le ts'ebeliso ea li-flame retardants tsa magnesium oxide lia hlokahala.
