I-Magnesium oxide
Iphrofayili yomkhiqizo
I-Magnesium oxide, iyinhlanganisela ye-inorganic, ifomula yamakhemikhali i-MgO, i-oxide ye-magnesium, iyinhlanganisela ye-ionic, emhlophe eqinile ekushiseni kwekamelo. I-Magnesium oxide ikhona emvelweni isesimweni se-magnesite futhi iyimpahla eluhlaza yokuncibilikisa i-magnesium.
I-Magnesium oxide inokumelana nomlilo okuphezulu kanye nezakhiwo zokuvikela. Ngemuva kokushisa okuphezulu okuvutha ngaphezu kuka-1000 ℃ kungaguqulwa kube amakristalu, kukhuphuke kuye ku-1500-2000 °C kube i-magnesium oxide efile eshile (i-magnesia) noma i-sintered magnesium oxide.
Inkomba Yezobuchwepheshe
Inkambu yohlelo lokusebenza:
Kungukunqunywa kwesibabule nepyrite emalahleni nesibabule ne-arsenic ensimbi. Isetshenziswa njengendinganiso yezingulube ezimhlophe. I-magnesium oxide ekhanyayo isetshenziswa kakhulu njengempahla eluhlaza ekulungiseni izitsha zobumba, ama-koqweqwe lwawo, izitini ze-refractory crucible kanye nezitini eziphikisayo. Ibuye isetshenziswe njengezinamatheliso ze-ejenti yokupholisha, okokunamathela, nezigcwalisi zephepha, i-neoprene kanye nama-accelerator enjoloba e-fluorine kanye nama-activator. Ngemuva kokuxuba ne-magnesium chloride nezinye izixazululo, amanzi e-magnesium oxide angalungiswa. Isetshenziswa kwezokwelapha njenge-antacid kanye ne-laxative ye-gastric acid ngokweqile kanye nesifo se-duodenal ulcer. Isetshenziswa embonini yamakhemikhali njenge-catalyst kanye nempahla eluhlaza ekwenzeni usawoti we-magnesium. Ibuye isetshenziswe ekwenzeni ingilazi, ukudla okudayiwe, amapulasitiki e-phenolic, njll. I-magnesium oxide enamandla isetshenziswa embonini yokugaya irayisi ukudubula ama-rollers nama-half rollers. Imboni yezokwakha yokukhiqiza ibhodi lamakhemikhali okwenziwa phansi elenziwe ngemabula yokufakelwa ibhodi lokufakwa komsindo webhodi lemboni yepulasitiki esetshenziswa njengokugcwalisa. Ingase futhi isetshenziselwe ukukhiqiza ezinye magnesium usawoti.
Enye yezindlela eziyinhloko ezisetshenziswa ngayo i-magnesium oxide ukusetshenziswa kwezinqamuleli zomlilo, izinto zendabuko ezibuyisela amalangabi, ama-polymer aqukethe i-halogen asetshenziswa kabanzi noma inhlanganisela ye-halogen-container flame retardants inhlanganisela ye-flame retardant. Kodwa-ke, lapho umlilo sewuba khona, ngenxa yokubola nokushisa okushisayo, uzokhipha intuthu enkulu kanye namagesi adlayo anobuthi, okuzovimbela ukulwa nomlilo kanye nokuphuma kwabasebenzi, ukugqwala kwezinsimbi nezinto zokusebenza. Ikakhulukazi, kutholakale ukuthi ngaphezu kwe-80% yokufa emlilweni kubangelwa umusi kanye namagesi anobuthi akhiqizwa impahla, ngakho-ke ngaphezu kokusebenza kahle komlilo, umusi ophansi kanye nobuthi obuphansi nakho kuyizinkomba ezibalulekile ze ama-flame retardants. Ukuthuthukiswa kwemboni yaseShayina evimbela amalangabi akulinganiseli ngokwedlulele, futhi ingxenye ye-chlorine retardants inzima uma kuqhathaniswa, okungeyokuqala yazo zonke izinto ezivimbela amalangabi, lapho upharafini one-chlorine esebenza yedwa. Kodwa-ke, ama-chlorine flame retardants akhipha amagesi anobuthi lapho enza, okude kakhulu nokuphishekela impilo yesimanje engenabuthi futhi ephumelelayo. Ngakho-ke, ukuze uhambisane nomkhuba wokuthuthukiswa kwentuthu ephansi, ubuthi obuphansi kanye nezinqamuleli zamalangabi ezingangcolisi emhlabeni, ukuthuthukiswa, ukukhiqizwa kanye nokusetshenziswa kwe-magnesium oxide flame retardants kubalulekile.
