Icyuma (III) oxyde CAS 1309-37-1 kumenyekanisha
ubuziranenge
Amacunga-umutuku kugeza ibara-umutuku trigonal kristaline. Ubucucike bugereranije 5. 24 point Ingingo yo gushonga 1565 ° C (kubora). Kudashonga mumazi, gushonga muri acide hydrochloric, aside sulfurike, gushonga gake muri acide ya nitric na alcool. Iyo yatwitse, umwuka wa ogisijeni urekurwa, ushobora kugabanywa fer na hydrogène na monoxyde de carbone. Gutatana neza, gusiga imbaraga no guhisha imbaraga. Nta mavuta yinjira kandi nta mazi yinjira. Irwanya ubushyuhe, irwanya urumuri, irwanya aside na alkali.
Uburyo
Hariho uburyo bwo gutegura butose kandi bwumye. Ibicuruzwa bitose bifite kristu nziza, ibice byoroshye, kandi byoroshye gusya, kuburyo bibereye pigment. Ibicuruzwa byumye bifite kristu nini nuduce twinshi, kandi birakwiriye ibikoresho bya magneti hamwe no gusya no gusya.
Uburyo butose: umubare munini wa 5% ferrous sulfate yumuti uhita uhita ukemurwa nigisubizo kirenze urugero cya soda ya caustic (birakenewe alkali ya 0.04 ~ 0.08g / mL), kandi umwuka winjizwa mubushyuhe bwicyumba kugirango byose bihinduke umutuku wijimye wijimye hydroxide colloidal igisubizo, ikoreshwa nka nucleus ya kirisiti yo kubitsa oxyde de fer. Hamwe na nucleus yavuzwe haruguru nk'utwara, hamwe na sulfate ferrous nk'ikigereranyo, umwuka utangizwa, kuri 75 ~ 85 ° C, hashingiwe ku kuba hari ibyuma byuma, sulfate ferrous ikora na ogisijeni mu kirere kubyara okiside ferricike (ni ukuvuga umutuku wicyuma) yashyizwe kuri nucleus ya kirisiti, na sulfate mugisubizo ikora hamwe nicyuma cyuma kugirango igarure sulfate ferrous, na sulfate ferrous ihindurwamo okiside itukura nicyuma na umwuka kandi ikomeza kubikwa, kugirango uruziga rurangire inzira yose kugirango habeho okiside itukura.
Uburyo bwumye: aside nitricike ifata amabati kugirango ikore nitrate ya ferrous, ikonjeshwa kandi ikabikwa, ikabura amazi kandi ikuma, ikabarwa kuri 600 ~ 700 ° C kuri 8 ~ 10h nyuma yo kuyisya, hanyuma ikakaraba, ikuma kandi ikajanjagurwa kugirango ibone okiside ya fer ibicuruzwa bitukura. Umuhondo w'icyuma umuhondo urashobora kandi gukoreshwa nkibikoresho fatizo, kandi umutuku wa okiside wicyuma urashobora kuboneka kubara kuri 600 ~ 700 ° C.
Koresha
Ni pigment idasanzwe kandi ikoreshwa nka pigment yo kurwanya ingese mu nganda. Ikoreshwa kandi nk'ibara rya reberi, marble artificiel, terrazzo hasi, amabara hamwe nuzuza plastike, asibesitosi, uruhu rwubukorikori, paste yimpu, nibindi, ibikoresho byo gusya kubikoresho byuzuye nibirahuri bya optique, nibikoresho fatizo bya gukora ibikoresho bya magnetiki ferrite.
umutekano
Gipfunyika mu mifuka iboshywe yuzuye imifuka ya pulasitike ya polyethylene, cyangwa igapakirwa mu mifuka yimpapuro 3 yububiko, ifite uburemere bwa 25 kg kuri buri mufuka. Igomba kubikwa ahantu humye, ntugire amazi, wirinde ubushyuhe bwinshi, kandi igomba gutandukanywa na aside na alkali. Igihe cyiza cyo kubika cya paki idafunguwe ni imyaka 3. Uburozi no kurinda: Umukungugu utera pneumoconiose. Ikigereranyo ntarengwa cyemewe mu kirere, icyuma cya okiside ya aerosol (soot) ni 5mg / m3. Witondere umukungugu.
