Intsimbi(III) oxide CAS 1309-37-1 yazisa
umgangatho
I-Orenji-bomvu ukuya kumgubo obomvu-obomvu oyikristale eyitrigonal. Ubuninzi obuzalanayo 5. 24. Indawo yokunyibilika 1565 °C (ukubola). Ayinyibiliki emanzini, i-soluble kwi-hydrochloric acid, i-sulfuric acid, i-soluble kancinane kwi-nitric acid kunye notywala. Xa utshisiwe, kuphuma ioksijini, enokuthi yehliswe ibe yintsimbi ngehydrogen necarbon monoxide. Ukusasazwa okulungileyo, ukuthamba okuqinileyo kunye namandla okufihla. Akukho ukunyanzeliswa kweoli kwaye akukho manzi. Ukumelana nobushushu, ukumelana nokukhanya, ukumelana ne-asidi kunye ne-alkali-resistant.
Indlela
Kukho iindlela zokulungiselela ezimanzi nezomileyo. Iimveliso ezimanzi zineekristale ezintle, iincinci ezithambileyo, kwaye zilula ukugaya, ngoko zifanelekile kwii-pigments. Iimveliso ezomileyo zineekristale ezinkulu kunye neengqungquthela ezinzima, kwaye zifanelekile kwizinto eziphathekayo zamagnetic kunye nokupolisha kunye nezinto zokugaya.
Indlela emanzi: umlinganiselo othile we-5% ye-ferrous sulfate isisombululo usabela ngokukhawuleza kunye nesisombululo se-caustic soda engaphezulu (i-alkali engaphezulu kwe-0.04 ~ 0.08g / mL iyafuneka), kwaye umoya ungeniswa kwiqondo lokushisa ukuze uguqule yonke into. isisombululo se-iron hydroxide colloidal ebomvu-brown, esetyenziswa njenge-crystal nucleus yokufaka i-iron oxide. Ngekristal nucleus ekhankanywe ngasentla njengomthwali, kunye ne-sulfate ye-ferrous njengendawo ephakathi, umoya ungeniswa, kwi-75 ~ 85 ° C, phantsi kwemeko yobukho bentsimbi yesinyithi, i-sulfate ene-ferrous isabela kunye ne-oksijini emoyeni. ukwenza i-ferric oxide (okt, intsimbi ebomvu) efakwe kwikristale nucleus, kunye nesulfate kwisisombululo idibana nentsimbi yesinyithi ukuze iphinde ikhule. i-sulfate ene-ferrous, kunye ne-sulfate ye-ferrous i-oxidized ibe yintsimbi ebomvu emoyeni kwaye iyaqhubeka ifakwe, ukuze umjikelo uphele ekupheleni kwayo yonke inkqubo yokuvelisa i-iron oxide ebomvu.
Indlela eyomileyo: i-nitric acid iphendula kunye namaphepha entsimbi ukwenza i-nitrate ene-ferrous, epholileyo kwaye ifakwe ikristale, iphelelwe ngamanzi kwaye yomiswe, kwaye ifakwe kwi-600 ~ 700 ° C ye-8 ~ 10h emva kokusila, emva koko ihlanjwe, yomiswe kwaye icolile ukufumana i-iron oxide. iimveliso ezibomvu. I-iron oxide etyheli isenokusetyenziswa njengemathiriyeli ekrwada, kwaye i-iron oxide ebomvu inokufunyanwa ngokubala ku-600~700 °C.
sebenzisa
Yi-pigment ye-inorganic kwaye isetyenziswa njenge-pigment echasene nomhlwa kwishishini lokugquma. Ikwasetyenziswa njengombala werabha, imabhule eyenziweyo, i-terrazzo emhlabeni, imibala kunye nokuzalisa iiplastiki, iasbestos, isikhumba sokwenziwa, intlama yokupolisha yesikhumba, njl. ukuveliswa kwezixhobo ze-ferrite magnetic.
ukhuseleko
Ipakishwe kwiingxowa ezilukiweyo ezifakwe iiplastiki zepolyethylene, okanye zipakishwe kwiingxowa zephepha ze-kraft ezi-3, ezinobunzima obungama-25kg kwingxowa nganye. Kufuneka igcinwe kwindawo eyomileyo, ingabi namanzi, igweme ukushisa okuphezulu, kwaye kufuneka ibe yodwa kwi-asidi kunye ne-alkali. Ixesha elisebenzayo lokugcina iphakheji elingavulwanga liyiminyaka emi-3. Ubuthi kunye nokukhuselwa: Uthuli lubangela i-pneumoconiosis. Ubuninzi bokugxininiswa okuvumelekileyo emoyeni, i-iron oxide aerosol (soot) yi-5mg / m3. Nika ingqalelo eluthulini.
