I-Iron(III) oxide CAS 1309-37-1 yethula
izinga
Okuwolintshi-okubomvu kuya kokuphephuli-bomvu okucwebezelayo okuyi-trigonal crystalline powder. Ukuminyana okuhlobene 5. 24. Iphuzu elincibilikayo 1565 °C (ukubola). Ayincibiliki emanzini, i-soluble ku-hydrochloric acid, i-sulfuric acid, i-soluble kancane ku-nitric acid notshwala. Lapho ushiswa, kukhishwa umoya-mpilo, ongancishiswa ube yi-iron nge-hydrogen ne-carbon monoxide. Ukuhlakazeka okuhle, ukuthamba okuqinile namandla okucasha. Akukho ukungena kwamafutha futhi akukho ukungena kwamanzi. Imelana nezinga lokushisa, imelana nokukhanya, imelana ne-asidi kanye ne-alkali.
Indlela
Kunezindlela zokulungiselela ezimanzi nezomile. Imikhiqizo emanzi inamakristalu amahle, izinhlayiya ezithambile, futhi kulula ukuyigaya, ngakho ilungele izingulube. Imikhiqizo eyomile inamakristalu amakhulu nezinhlayiya eziqinile, futhi ifaneleka izinto kazibuthe kanye nezinto zokupholisha nokugaya.
Indlela emanzi: isilinganiso esithile sesisombululo se-ferrous sulfate esingu-5% sisabela ngokushesha ngesisombululo se-caustic soda eseqile (kudingeka i-alkali eyeqile engu-0.04~0.08g/mL), futhi umoya wethulwa ezingeni lokushisa elilingana negumbi ukuze uguqule wonke isisombululo se-iron hydroxide colloidal esibomvu ngokubomvu, esisetshenziswa njenge-crystal nucleus yokufaka i-iron oxide. Nge-crystal nucleus eshiwo ngenhla njengomthwali, ene-ferrous sulfate njengendawo ephakathi, umoya wethulwa, ku-75 ~ 85 °C, ngaphansi kwesimo sokuba khona kwensimbi yensimbi, i-ferrous sulfate isabela nomoya-mpilo emoyeni. ukukhiqiza i-ferric oxide (okungukuthi, okubomvu kwe-iron) efakwe ku-crystal nucleus, futhi i-sulfate esesixazululweni ihlangana ne-metallic iron ukuze ikhiqize kabusha. i-ferrous sulfate, kanye ne-ferrous sulfate ikhishwa emoyeni ibe insimbi ebomvu futhi iqhubeke ifakwa, ukuze umjikelezo uphele ekupheleni kwayo yonke inqubo ukuze kukhiqizwe i-iron oxide ebomvu.
Indlela eyomile: i-nitric acid iphendula ngamashidi ensimbi ukuze yakhe i-nitrate ene-ferrous, epholiswa futhi ifakwe ikristalu, iphelelwe amanzi futhi yomiswe, bese ifakwa ku-600 ~ 700 ° C amahora angu-8 ~ 10 ngemva kokugaya, bese igezwa, yomiswe futhi ichotshozwe ukuze kutholakale i-iron oxide. imikhiqizo ebomvu. I-iron oxide yellow ingasetshenziswa njengempahla eluhlaza, futhi i-iron oxide ebomvu ingatholwa ngokubala ku-600 ~ 700 °C.
sebenzisa
I-pigment ye-inorganic futhi isetshenziswa njenge-anti-rust pigment embonini yokumboza. Ibuye isetshenziswe njengombala wenjoloba, imabula yokwenziwa, i-terrazzo phansi, ama-colorants nama-filler amapulasitiki, i-asbestos, isikhumba sokwenziwa, isikhumba sokunamathisela, njll., i-ejenti yokupholisha yezinsimbi ezinembayo nengilazi ebonakalayo, nezinto zokusetshenziswa ukwakhiwa kwezakhi ze-ferrite kazibuthe.
ezokuphepha
Ipakishwe ezikhwameni ezilukiwe ezifakwe izikhwama zepulasitiki ze-polyethylene, noma zipakishwe ezikhwameni zephepha ze-kraft ezinezingqimba ezi-3, ezinesisindo esinetha esingu-25kg isikhwama ngasinye. Kufanele igcinwe endaweni eyomile, ingatholi umswakama, igweme izinga lokushisa eliphezulu, futhi kufanele ihlukaniswe ne-asidi ne-alkali. Isikhathi sokugcina esisebenzayo sephakheji elingavuliwe iminyaka emi-3. Ubuthi nokuvikelwa: Uthuli lubangela i-pneumoconiosis. Isilinganiso esiphezulu esivumelekile emoyeni, i-iron oxide aerosol (soot) ngu-5mg/m3. Naka izintuli.
