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 amanye amasawoti e-magnesium.
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 akhulula 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.
