I-Titanium(IV) i-oxide CAS 13463-67-7 Intshayelelo
umgangatho
Umgubo omhlophe we-amorphous. Kukho iintlobo ezintathu ze-titanium dioxide ezikhoyo kwindalo: i-rutile yikristale ye-tetragonal; I-Anatase yikristale ye-tetragonal; I-Plate perovskite yikristale ye-orthorhombic. Mthubi kubushushu obuncinci kwaye ubemdaka kubushushu obunamandla. I-insoluble emanzini, i-hydrochloric acid okanye i-nitric acid okanye i-dilute sulfuric acid kunye ne-solvents ye-organic, i-soluble kwi-concentrated sulfuric acid, i-hydrofluoric acid, i-soluble kancinane kwi-alkali kunye ne-asidi ye-nitric eshushu. Inokubiliswa ixesha elide ukunyibilika kwi-asidi ye-sulfuric concentrated kunye ne-hydrofluoric acid. Isabela kunye ne-sodium hydroxide etyhidiweyo ukwenza i-titanate. Kubushushu obuphezulu, inokwehliswa kwi-titanium ephantsi-valent nge-hydrogen, i-carbon, i-sodium yensimbi, njl., kwaye iphendule nge-carbon disulfide ukwenza i-titanium disulfide. Isalathiso se-refractive se-titanium dioxide sesona sikhulu kwibala elimhlophe, kwaye uhlobo lwe-rutile luyi-8. 70, 2.55 yohlobo lwe-anatase. Ukusukela ukuba zombini i-anatase kunye nepleyiti yetitanium dioxide iguquka ibe yirutile kumaqondo obushushu aphezulu, iindawo zokunyibilika kunye nokubila kwepleyiti yetitanium kunye neanatase azikho kwaphela. Kuphela i-rutile titanium dioxide enendawo yokunyibilika kunye nendawo yokubila, indawo yokunyibilika ye-rutile titanium dioxide yi-1850 °C, indawo yokunyibilika emoyeni ngu (1830 emhlabeni 15) °C, kwaye indawo yokunyibilika ekutyebiseni ioksijini yi-1879 °C. , kwaye indawo yokunyibilika ihambelana nokucoceka kwe-titanium dioxide. Indawo yokubila yerutile titanium dioxide yi (3200 umhlaba 300) K, kwaye titanium dioxide iyaguquguquka kancinci kobu bushushu buphezulu.
Indlela
I-industrial titanium oxide sulfate inyibilika emanzini kwaye ihluziwe. I-ammonia yongezwa ukuze iqhube imvula efana ne-gauntlet, kwaye emva koko yahluzwa. Emva koko ichithwe ngesisombululo se-oxalic acid, kwaye emva koko ihlanjululwe kwaye ihluzwe nge-ammonia. Imvula efunyenweyo iyomiswa kwi-170 °C ize yosiwe kwi-540 °C ukufumana i-titanium dioxide ecocekileyo.
Uninzi lwazo zezemigodi evulekileyo. I-Titanium primary ore beneficiation inokwahlulwa ibe zizigaba ezithathu: pre-separation (edla ngokusetyenziswa ukuhlukana kwamagnetic kunye nendlela yokwahlula ubunzima), ukwahlukana kwentsimbi (indlela yokwahlula imagnetic), kunye nokwahlulwa kwe-titanium (ukwahlulwa komxhuzulane, ukwahlula kwamagnetic, ukwahlula kombane kunye nendlela yokudada). Uncedo lweendawo zokubeka i-titanium zirconium (ubukhulu becala abagcini bonxweme, belandelwa ngababeki bangaphakathi kwelizwe) kunokohlulwa kube ngamanqanaba amabini: ukwahlukana okurhabaxa kunye nokukhetha. Ngo-1995, iZiko loPhando oluBanzi loPhando lwaseZhengzhou loMphathiswa weGeology kunye neMineral Resources lwamkela inkqubo yokwahlulwa kwamagnetic, ulwahlulo lomxhuzulane kunye nokuphuma kweasidi ukuze kuxhamle umgodi omkhulu werutile eXixia, kwiPhondo laseHenan, ophumelele ukuveliswa kovavanyo, kwaye zonke izalathisi zikwinqanaba eliphambili eTshayina.
sebenzisa
Isetyenziswe njenge-reagent yohlalutyo lwe-spectral, ukulungiswa kweetyuwa ze-titanium ezicocekileyo, ii-pigments, i-polyethylene colorants, kunye ne-abrasives. Ikwasetyenziswa kumzi mveliso wamachiza, i-capacitive dielectric, i-alloys enganyangekiyo kubushushu obuphezulu, kunye nokuveliswa kwesiponji se-titanium ukumelana nobushushu obuphezulu.
Isetyenziselwa ukwenza i-titanium dioxide, i-titanium sponge, i-titanium alloy, i-artificial rutile, i-titanium tetrachloride, i-titanium sulfate, i-potassium fluorotitanate, i-aluminiyam i-titanium chloride, njl. , ii-coatings, i-welding electrode kunye ne-rayon yokunciphisa ukukhanya, iiplastiki kunye izigcwalisi zamaphepha ezikumgangatho ophezulu, kwaye zikwasetyenziswa kwizixhobo zonxibelelwano, isinyithi, ukuprinta, ukuprinta kunye nokudaya, i-enamel kunye namanye amasebe. I-Rutile ikwayeyona nto iphambili yezimbiwa ekrwada yokusulungekisa i-titanium. I-Titanium kunye ne-alloys yayo ineempawu ezibalaseleyo ezifana namandla aphezulu, ubuninzi obuphantsi, ukuxhathisa ukubola, ukuxhathisa ubushushu obuphezulu, ukumelana nobushushu obuphantsi, ukungabi natyhefu, njl. inqwelomoya, ishishini lamachiza, ishishini ukukhanya, navigation, ezonyango, ukhuselo lwesizwe kunye nophuhliso lwemithombo yolwandle kunye nezinye iinkalo. Ngaphezulu kwe-90% ye-titanium minerals yehlabathi isetyenziselwa ukuvelisa i-titanium dioxide white pigments, kwaye le mveliso isetyenziswa kakhulu kwipeyinti, irabha, iiplastiki, amaphepha kunye namanye amashishini.
ukhuseleko
Gcina kwindawo epholileyo nengena umoya. Iphakheji ivaliwe. Ayinakugcinwa kwaye ixutywe neeasidi.
Iimveliso zeminerali ezinqabileyo aziyi kuxutywa kunye ne-sundries zangaphandle kwinkqubo yokupakishwa, ukugcinwa kunye nokuthutha. Impahla yengxowa yokupakisha iyafuneka ukuba inganyangeki kwaye ingabi lula ukuyiqhekeza. Ukupakishwa kwengxowa ephindwe kabini, iileya zangaphakathi kunye nangaphandle kufuneka zihambelane, umaleko wangaphakathi yingxowa yeplastiki okanye isikhwama selaphu (iphepha le-kraft lingasetyenziswa), kwaye umaleko wangaphandle yingxowa ephothiweyo. Ubunzima obushiyekileyo bephakheji nganye ngama-25kg okanye ama-50kg. Xa upakisha, umlomo wesikhwama kufuneka uvalwe ngokuqinileyo, kwaye i-logo kwisikhwama kufuneka iqine, kunye nokubhala ngesandla kufuneka kucace kwaye kungapheli. Ibhetshi nganye yeemveliso zezimbiwa iya kukhatshwa sisiqinisekiso somgangatho esihlangabezana neemfuno zomgangatho. Ukugcinwa kweemveliso zamaminerali kufuneka kufakwe kumanqanaba ahlukeneyo, kwaye indawo yokugcina kufuneka icoceke.
