Iron(III) oxide CAS 1309-37-1 suma
quality
Orange-tsvuku kuita purplish-tsvuku trigonal crystalline poda. Relative density 5. 24. Melting point 1565 °C (decomposition). Isoluble mumvura, soluble muhydrochloric acid, sulfuric acid, inonyungudika zvishoma munitric acid nedoro. Kana yapiswa, okisijeni inosunungurwa, iyo inogona kuderedzwa kuita iron nehydrogen uye carbon monoxide. Kupararira kwakanaka, tinting yakasimba uye simba rekuhwanda. Hapana kupindira kwemafuta uye hakuna kupindira kwemvura. Inodzivirira tembiricha, isingavheneke, inodzivirira asidhi uye inodzivirira alkali.
Nzira
Kune nzira dzekugadzirira dzakanyorova uye dzakaoma. Zvigadzirwa zvakanyorova zvine makristasi akanaka, zvinyoro zvinyoro, uye zviri nyore kugaya, saka zvakakodzerwa nepigment. Zvigadzirwa zvakaomeswa zvine makristasi makuru uye zvimedu zvakaoma, uye zvakakodzerwa nemagineti zvinhu uye kukwenenzverwa nekukuya zvinhu.
Nzira yekunyorova: imwe chiyero che5% ferrous sulfate solution inokurumidza kubatwa necaustic soda solution yakawandisa (yakawandisa alkali ye0.04 ~ 0.08g/mL inodiwa), uye mhepo inounzwa patembiricha yekamuri kuti iite kuti ishanduke. yakatsvuka-brown iron hydroxide colloidal solution, iyo inoshandiswa sekristaro nucleus yekuisa iron oxide. Iine crystal nucleus yataurwa pamusoro semutakuri, ine ferrous sulfate sepakati, mhepo inounzwa, pa75 ~ 85 ° C, pasi pemamiriro ekuvapo kwesimbi yesimbi, iyo ferrous sulfate inopindirana neokisijeni mumhepo. kugadzira ferric oxide (kureva, iron tsvuku) yakaiswa pakristaro nucleus, uye sulfate iri mumhinduro inopindirana nesimbi yesimbi kuti iitezve. ferrous sulfate, uye iyo ferrous sulfate inoiswa oxidized musimbi tsvuku nemhepo uye inoramba ichiiswa, kuitira kuti kutenderera kunopera pakupera kwekuita kwese kuburitsa iron oxide tsvuku.
Dry method: nitric acid inopindirana nesimbi mashizha kuti iite ferrous nitrate, iyo yakatonhodzwa uye yakanatswa, yakasvibiswa uye yakaomeswa, uye yakakonzerwa pa 600 ~ 700 ° C kwe8 ~ 10h mushure mekuya, uye yobva yashambidzwa, yakaomeswa uye yakapwanyika kuti iwane iron oxide. zvigadzirwa zvitsvuku. Iron oxide yero inogonawo kushandiswa seyakabikwa, uye iron oxide tsvuku inogona kuwanikwa nekuverengera pa600 ~ 700 °C.
use
Iyo inorganic pigment uye inoshandiswa se anti-rust pigment muindasitiri yekupfeka. Inoshandiswawo seruvara rwerabha, marble ekugadzira, terrazzo pasi, mavara uye mafirita emapurasitiki, asbestos, ganda rekugadzira, dehwe rekupolisha paste, nezvimwewo, mumiriri wekupolisha wezviridzwa zvine hunyanzvi uye girazi remaziso, uye zvigadzirwa zve kugadzirwa kwemagnetic ferrite components.
kuchengeteka
Yakaiswa mumabhegi akarukwa akaiswa polyethylene epurasitiki mabhegi, kana kurongedzerwa mumapepa matatu-layer kraft mapepa, ane huremu hwemambure e25kg pabhegi. Inofanira kuchengetwa munzvimbo yakaoma, irege kunyorova, dzivisa kupisa kwakanyanya, uye inofanira kuparadzaniswa kubva kune acid uye alkali. Iyo inobudirira yekuchengetedza nguva yepakiti isina kuvhurwa ndeye makore matatu. Toxicity uye kudzivirira: Guruva rinokonzera pneumoconiosis. Iyo yakawanda inobvumirwa kusungirirwa mumhepo, iron oxide aerosol (soot) ndeye 5mg/m3. Chenjerera kuguruva.
