Titanium(IV) oxide CAS 13463-67-7 Hordhac
tayada
Budada amorphous cad. Waxaa jira saddex nooc oo titanium dioxide ah oo ka jira dabeecadda: rutile waa crystal tetragonal; Anatase waa crystal tetragonal; Plate perovskite waa crystal orthorhombic. Jaalle inyar kuleyl ah iyo bunni kulayl xoog leh. Asiidh aan biyo ku milmin, hydrochloric acid ama nitric acid ama milmi sulfuric acid iyo dareerayaasha organic, ku milmay sulfuric acid, hydrofluoric acid, wax yar ku milmay alkali iyo nitric acid kulul. Waa la karkarin karaa wakhti dheer si ay ugu milanto sulfuric acid iyo hydrofluoric acid. Waxay la falgashaa sodium hydroxide dhalaalaysa si ay u samayso titanate. Heerkulka sare, waxaa lagu dhimi karaa titanium-ka hooseeya ee hydrogen, carbon, birta sodium, iwm. Tilmaanta refractive ee titanium dioxide waa tan ugu weyn ee midabada cad, iyo nooca rutile waa 8. 70, 2.55 nooca anatase. Maaddaama anatase iyo titanium dioxide labadaba ay isu beddelaan rutile heerkulka sare, dhalaalka iyo karkarinta ee titanium saxan iyo anatase waa wax aan jirin. Kaliya rutile titanium dioxide ayaa leh bar dhalaalaysa iyo barta karkaraya, barta dhalaalaysa ee titanium dioxide waa 1850 ° C, barta dhalaalaysa hawadu waa (1830 dhulka 15) °C, barta dhalaalaysa ee kobcinta ogsijiinta waa 1879 ° C. , iyo barta dhalaalaysa waxay la xiriirtaa nadiifnimada titanium dioxide. Meesha karkaraya ee titanium dioxide rutile waa (3200 carro 300) K, iyo titanium dioxide wax yar ayaa kacsan heerkulkan sarreeya.
Habka
Warshadaynta titanium oxide sulfate waxa lagu milmaa biyaha oo la sifeeyaa. Ammonia ayaa lagu daray si ay u soo dedejiso biyo-soo-bax u eg gauntlet, ka dibna la sifeeyay. Kadibna waxaa lagu milmaa xalalka oxalic acid, ka dibna la soo dajiyo oo lagu sifeeyo ammonia. Da'da la helay ayaa lagu qallajin doonaa 170 ° C ka dibna lagu dubay 540 ° C si loo helo titanium dioxide saafi ah.
Badankoodu waa macdan qodis god furan. Ka faa'iidaysiga macdanta aasaasiga ah ee Titanium waxaa loo qaybin karaa saddex marxaladood: kala-soocidda hore (sida caadiga ah loo isticmaalo kala-soocidda magnetic iyo habka kala-soocidda cuf-jiidadka), kala-soocidda birta (habka kala-soocidda magnetic), iyo kala-soocidda titanium (kala-soocidda culeyska, kala-soocidda magnetic, kala-soocidda korantada iyo habka sabbeynta). Ka faa'iidaysiga boosaska titanium zirconium (badanaa meelaha xeebaha ah, oo ay ku xigto meeleeyayaasha gudaha) waxa loo qaybin karaa laba marxaladood: kala saarid qallafsan iyo xulashada. 1995-kii, Machadka Cilmi-baarista ee Isticmaalka Guud ee Zhengzhou ee Wasaaradda Geology iyo Khayraadka Macdanta ayaa ansixiyay habka kala-soocidda magnetic, kala-soocidda cuf-isjiidadka iyo dheecaanka aashitada si ay uga faa'iideystaan miinada rutile ee dheeraadka ah ee Xixia, Gobolka Henan, oo soo saartay wax soo saar tijaabo ah, iyo dhammaan tilmaamayaasha waxay ku sugan yihiin heerka ugu horreeya ee Shiinaha.
isticmaal
Waxaa loo istcimaalaa sidii falanqeyn muuqaal ah, diyaarinta cusbada titanium-ka saafiga ah, pigments, midabada polyetylen, iyo abrasives. Waxa kale oo loo isticmaalaa warshadaha dawooyinka, dielectric capacitive, alloys u adkaysta heerkulka sare, iyo heerkul sare u adkaysta titanium isbuunyada.
Waxaa loo isticmaalaa in lagu sameeyo titanium dioxide, titanium sponge, titanium alloy, rutile macmal ah, titanium tetrachloride, titanium sulfate, fluorotitanate potassium, aluminium titanium chloride, iwm , dahaarka, electrodes alxanka iyo rayn-iftiin yareeya wakiilada, balaastikada iyo buuxinta warqad heer sare ah, iyo sidoo kale waxaa loo isticmaalaa in qalabka isgaarsiinta, biraha, daabacaadda, daabacaadda iyo rinjiyeynta, dhaldhalaalka iyo waaxyo kale. Rutile sidoo kale waa alaabta ceeriin ee macdanta ugu weyn ee lagu sifeeyo titanium. Titanium iyo Alloys-ku waxay leeyihiin sifooyin aad u wanaagsan sida xoog sare, cuf yar, iska caabin daxalka, iska caabinta heerkulka sare, iska caabinta heerkulka hooseeya, sunta aan sunta ahayn, iwm. duulista, warshadaha kiimikada, warshadaha iftiinka, navigation, caafimaadka, difaaca qaranka iyo horumarinta khayraadka badda iyo beeraha kale. In ka badan 90% macdanta titanium-ka adduunka ayaa loo isticmaalaa in lagu soo saaro midabada cad cad ee titanium dioxide, badeecadan ayaa aad iyo aad loogu isticmaalaa rinjiga, cinjirka, balaastikada, waraaqaha iyo warshadaha kale.
amniga
Ku kaydi bakhaar qabow oo hawo leh. Xidhmada waa la xidhay. Lama kaydin karo laguna qasi karo asiidh.
Wax soo saarka macdanta rutile waa in aan lagu qasin noocyo shisheeye ah habka baakadaha, kaydinta iyo gaadiidka. Maaddada bacaha ayaa looga baahan yahay inay noqoto mid u adkaysata daxalka oo aanay fududayn in la jebiyo. Baakadaha laba-lakabka ah, lakabyada gudaha iyo dibedda waa in la is waafajiyaa, lakabka gudaha waa bac caag ah ama bac maro ah (waraaqda kraft sidoo kale waa la isticmaali karaa), lakabka sare waa bac tolan. Miisaanka saafiga ah ee xirmo kasta waa 25kg ama 50kg. Marka la xidhidhinayo, afka bacda waa in si adag loo xidhaa, calaamada bacdana waa in ay ahaataa mid adag, fartuna waa in ay noqotaa mid cad oo aan libdhin. Qayb kasta oo macdanta macdanta ah waa in ay la socotaa shahaado tayo leh oo buuxinaysa shuruudaha heerka. Kaydinta wax soo saarka macdanta waa in lagu dhejiyaa darajooyin kala duwan, iyo goobta kaydinta waa inay ahaato mid nadiif ah.
