I-Titanium(IV) i-oxide CAS 13463-67-7 Isingeniso
izinga
Impushana emhlophe e-amorphous. Kunezinhlobo ezintathu ze-titanium dioxide ezikhona emvelweni: i-rutile iyikristalu ye-tetragonal; I-Anatase iyikristalu ye-tetragonal; I-Plate perovskite iyikristalu ye-orthorhombic. Ophuzi ngokushisa kancane futhi ube nsundu ekushiseni okunamandla. Ayincibiliki emanzini, i-hydrochloric acid noma i-nitric acid noma i-dilute sulfuric acid nezinyibilikisi eziphilayo, inyibilika ku-concentrated sulfuric acid, i-hydrofluoric acid, inyibilika kancane ku-alkali ne-nitric acid eshisayo. Ingabiliswa isikhathi eside ukuze incibilike ku-concentrated sulfuric acid kanye ne-hydrofluoric acid. Ihlangana ne-sodium hydroxide encibilikisiwe ukwenza i-titanate. Emazingeni okushisa aphezulu, ingancishiswa ibe yi-titanium ephansi nge-hydrogen, ikhabhoni, i-sodium yensimbi, njll., futhi isabelane ne-carbon disulfide yenze i-titanium disulfide. Inkomba ye-refractive ye-titanium dioxide inkulu kunazo zonke ezinemibala emhlophe, futhi uhlobo lwe-rutile luyi-8. 70, 2.55 yohlobo lwe-anatase. Njengoba kokubili i-anatase ne-plate titanium dioxide ishintsha ibe i-rutile emazingeni okushisa aphezulu, amaphuzu ancibilikayo kanye abilayo epuleti le-titanium ne-anatase awekho nhlobo. I-rutile titanium dioxide kuphela enephuzu lokuncibilika nendawo ebilayo, indawo yokuncibilika ye-rutile titanium dioxide ingu-1850 °C, indawo yokuncibilika emoyeni ingu (1830 Earth 15) °C, kanti indawo yokuncibilika ekunotheni komoyampilo ngu-1879 °C. , futhi indawo yokuncibilika ihlobene nokuhlanzeka kwe-titanium dioxide. Iphuzu elibilayo le-rutile titanium dioxide lingu-(3200 inhlabathi 300) K, futhi i-titanium dioxide iyaguquguquka kancane kulokhu kushisa okuphezulu.
Indlela
I-Industrial titanium oxide sulfate incibilika emanzini futhi iyahlungwa. I-ammonia yengezwe ukuze kuncishiswe imvula efana ne-gauntlet, bese iyahlungwa. Bese ichitheka ngesisombululo se-oxalic acid, bese ihlanjululwa futhi ihlungwe nge-ammonia. Imvula etholiwe yomiswa ku-170 °C bese yosiwa ku-540 °C ukuze kutholwe i-titanium dioxide emsulwa.
Iningi lazo yizimayini zemigodi evulekile. I-Titanium primary ore beneficiation ingahlukaniswa ngezigaba ezintathu: pre-separation (evame ukusetshenziswa ngokuhlukanisa kazibuthe kanye nendlela yokuhlukanisa amandla adonsela phansi), ukuhlukaniswa kwensimbi (indlela yokuhlukanisa kazibuthe), kanye nokuhlukaniswa kwe-titanium (ukuhlukaniswa kwamandla adonsela phansi, ukuhlukaniswa kazibuthe, ukuhlukaniswa kukagesi kanye nendlela yokuntanta). Ukuzuza kwezindawo ezibeka i-titanium zirconium (ikakhulukazi izindawo ezihlala ogwini, ezilandelwa yizindawo ezihlala phakathi nezwe) zingahlukaniswa zibe izigaba ezimbili: ukuhlukaniswa okunzima nokukhetha. Ngo-1995, i-Zhengzhou Comprehensive Utilization Research Institute of the Ministry of Geology and Mineral Resources yamukela inqubo yokuhlukanisa kazibuthe, ukuhlukaniswa kwamandla adonsela phansi kanye ne-acid leaching ukuze kuzuzwe imayini ye-rutile enkulu e-Xixia, eSifundazweni sase-Henan, esiphumelele ukukhiqizwa kwesivivinyo, kanye zonke izinkomba zisezingeni eliphambili eChina.
sebenzisa
Isetshenziswa njenge-reagent yokuhlaziya i-spectral, ukulungiswa kosawoti we-titanium ohlanzekile kakhulu, izingulube, ama-colorethylene colorants, nama-abrasives. Ibuye isetshenziswe embonini yezemithi, i-capacitive dielectric, ama-alloys amelana nezinga lokushisa eliphezulu, kanye nokukhiqizwa kwesipontshi se-titanium ukumelana nokushisa okuphezulu.
Isetshenziselwa ukwenza i-titanium dioxide, i-titanium sponge, i-titanium alloy, i-artificial rutile, i-titanium tetrachloride, i-titanium sulfate, i-potassium fluorotitanate, i-aluminium titanium chloride, njll. I-titanium dioxide ingasetshenziswa ukwenza upende omhlophe wezinga eliphezulu, irabha emhlophe, imicu yokwenziwa. , ama-coatings, ama-welding electrode nama-rayon light-reducing agents, amapulasitiki kanye izigcwalisi zephepha ezisezingeni eliphezulu, futhi zisetshenziswa nasemishinini yezokuxhumana, i-metallurgy, ukuphrinta, ukuphrinta nokudaya, i-enamel neminye iminyango. I-Rutile futhi iyi-mineral raw material eyinhloko yokucwenga i-titanium. I-Titanium nama-alloys ayo anezakhiwo ezinhle kakhulu njengamandla aphezulu, ukuminyana okuphansi, ukumelana nokugqwala, ukumelana nezinga lokushisa eliphansi, ukumelana namazinga okushisa aphansi, ukungabi nobuthi, njll., futhi anemisebenzi ekhethekile njengokumuncwa kwegesi kanye ne-superconductivity, ngakho asetshenziswa kabanzi ezondiza, imboni yamakhemikhali, imboni elula, ukuhamba ngemikhumbi, ezokwelashwa, ezokuvikela kuzwelonke kanye nokuthuthukiswa kwezinsiza zasolwandle kanye neminye imikhakha. Ngaphezu kwamaphesenti angama-90 wamaminerali e-titanium emhlabeni asetshenziselwa ukukhiqiza i-titanium dioxide emhlophe yombala, futhi lo mkhiqizo usetshenziswa kabanzi kupende, irabha, amapulasitiki, amaphepha kanye nezinye izimboni.
ezokuphepha
Gcina endaweni epholile, engenisa umoya. Iphakheji ivaliwe. Ayikwazi ukugcinwa futhi ixutshwe nama-asidi.
Imikhiqizo yamaminerali ayigugu akufanele ihlanganiswe ne-sundries yangaphandle ngesikhathi sokupakishwa, ukugcinwa kanye nokuthutha. Impahla yesikhwama sokupakisha iyadingeka ukuze imelane nokugqwala futhi kungabi lula ukuphuka. Ukupakishwa kwesikhwama se-Double-layer, izingqimba zangaphakathi nangaphandle kufanele zifaniswe, isendlalelo sangaphakathi yisikhwama sepulasitiki noma isikhwama sendwangu (iphepha le-kraft lingasetshenziswa), kanti ungqimba lwangaphandle yisikhwama esilukiwe. Isisindo esisele sephakheji ngalinye singama-25kg noma ama-50kg. Lapho upakisha, umlomo wesikhwama kufanele uvalwe ngokuqinile, futhi uphawu esikhwameni kufanele luqine, nokubhala ngesandla kufanele kucace futhi kungapheli. Iqoqo ngalinye lemikhiqizo yamaminerali kufanele lihambisane nesitifiketi sekhwalithi esihlangabezana nezidingo zaleli zinga. Ukugcinwa kwemikhiqizo yamaminerali kufanele kupakishwe ngezigaba ezahlukene, futhi indawo yokugcina kufanele ihlanzeke.
