Iron (III) oxide CAS 1309-37-1 gabatarwa
inganci
Orange-ja zuwa purplish-ja trigonal crystalline foda. Dangantaka mai yawa 5. 24. Matsayin narkewa 1565 °C (ruɓuwa). Mai narkewa a cikin ruwa, mai narkewa a cikin hydrochloric acid, sulfuric acid, mai narkewa a cikin nitric acid da barasa. Lokacin da aka ƙone, ana fitar da iskar oxygen, wanda za a iya rage shi zuwa ƙarfe ta hanyar hydrogen da carbon monoxide. Kyakkyawan tarwatsawa, mai ƙarfi tinting da ikon ɓoyewa. Babu ƙorafin mai kuma babu ruwa. Yanayin zafi, juriya mai haske, juriya acid da juriya alkali.
Hanya
Akwai hanyoyin shirye-shiryen rigar da bushewa. Kayayyakin rigar suna da lu'ulu'u masu kyau, barbashi masu laushi, kuma suna da sauƙin niƙa, don haka sun dace da pigments. Abubuwan busassun suna da manyan lu'ulu'u da barbashi masu wuya, kuma sun dace da kayan maganadisu da polishing da kayan niƙa.
Hanyar rigar: wani adadin 5% na ferrous sulfate bayani yana amsawa da sauri tare da maganin soda mai wuce haddi (ana buƙatar alkali mai yawa na 0.04 ~ 0.08g / ml), kuma ana gabatar da iska a dakin da zafin jiki don sa shi duka ya zama. baƙin ƙarfe hydroxide colloidal bayani ja-launin ruwan kasa, wanda ake amfani da shi azaman crystal tsakiya don ajiye baƙin ƙarfe oxide. Tare da kristal tsakiya da aka ambata a sama a matsayin mai ɗauka, tare da sulfate na ferrous a matsayin matsakaici, ana gabatar da iska, a 75 ~ 85 ° C, a ƙarƙashin yanayin kasancewar ƙarfe na ƙarfe, ferrous sulfate yana amsawa tare da iskar oxygen a cikin iska. don samar da ferric oxide (watau jan ƙarfe) wanda aka ajiye akan tsakiyan crystal, kuma sulfate a cikin maganin yana amsawa da ƙarfe na ƙarfe don sake haɓaka ferrous. Sulfate, kuma ferrous sulfate yana oxidized zuwa baƙin ƙarfe ja ta iska kuma yana ci gaba da adanawa, ta yadda za a yi zagayowar ta ƙare a ƙarshen tsarin duka don samar da ƙarfe oxide ja.
Hanyar bushewa: nitric acid yana amsawa tare da zanen ƙarfe don samar da nitrate na ƙarfe, wanda aka sanyaya kuma a sanya shi cikin ruwa, an bushe shi kuma a bushe, kuma a sanya shi a 600 ~ 700 ° C na 8 ~ 10h bayan an niƙa, sannan a wanke, bushe da niƙa don samun baƙin ƙarfe oxide. ja kayayyakin. Iron oxide yellow kuma za a iya amfani da matsayin albarkatun kasa, da baƙin ƙarfe oxide ja za a iya samu ta calcination a 600 ~ 700 ° C.
amfani
Yana da wani inorganic pigment da kuma amfani da matsayin anti-tsatsa pigment a shafi masana'antu. Hakanan ana amfani dashi azaman mai launi don roba, marmara na wucin gadi, terrazzo a ƙasa, masu launi da masu cikawa don robobi, asbestos, fata na wucin gadi, man goge fata na fata, da sauransu, wakili na gogewa don ainihin kayan kida da gilashin gani, da albarkatun ƙasa don yi na Magnetic ferrite aka gyara.
tsaro
Cike a cikin jakunkuna masu saƙa saƙa da jakunkuna na filastik polyethylene, ko kuma an cika su a cikin jakunkuna na kraft mai Layer 3, tare da nauyin net ɗin 25kg kowace jaka. Ya kamata a adana shi a busasshen wuri, kada a sami danshi, kauce wa yawan zafin jiki, kuma ya kamata a ware daga acid da alkali. Tsawon lokacin ajiya mai inganci na kunshin da ba a buɗe ba shine shekaru 3. Guba da kariya: kura tana haifar da pneumoconiosis. Matsakaicin adadin da aka yarda da shi a cikin iska, baƙin ƙarfe oxide aerosol (soot) shine 5mg/m3. Kula da ƙura.
