Titaniyamu(IV) oxide CAS 13463-67-7 Chiyambi
khalidwe
White amorphous ufa. Pali mitundu itatu ya titaniyamu woipa yomwe ilipo m'chilengedwe: rutile ndi tetragonal crystal; Anatase ndi tetragonal crystal; Plate perovskite ndi orthorhombic crystal. Yellow potentha pang'ono ndi bulauni potentha kwambiri. Insoluble m'madzi, hydrochloric acid kapena nitric acid kapena kuchepetsa sulfuric acid ndi organic solvents, sungunuka mu anaikira sulfuric acid, hydrofluoric acid, sungunuka pang'ono mu alkali ndi otentha nitric asidi. Ikhoza kuwiritsa kwa nthawi yayitali kuti isungunuke mu sulfuric acid ndi hydrofluoric acid. Imachita ndi sodium hydroxide yosungunuka kupanga titanate. Pa kutentha kwambiri, imatha kuchepetsedwa kukhala titaniyamu yotsika kwambiri ndi hydrogen, carbon, metal sodium, etc., ndikuchitapo kanthu ndi carbon disulfide kupanga titaniyamu disulfide. Mndandanda wa refractive wa titaniyamu woipa ndi waukulu kwambiri mumitundu yoyera, ndipo mtundu wa rutile ndi 8. 70, 2.55 wa mtundu wa anatase. Popeza anatase ndi mbale titaniyamu woipa amasintha kukhala rutile pa kutentha kwambiri, kusungunuka ndi kuwira kwa mbale titaniyamu ndi anatase kulibe. Ndi rutile titanium dioxide yokha yomwe imakhala ndi malo osungunuka ndi malo otentha, malo osungunuka a rutile titanium dioxide ndi 1850 °C, malo osungunuka mumlengalenga ndi (1830 Earth 15) °C, ndi malo osungunuka mu 1879 °C. , ndipo malo osungunuka amagwirizana ndi chiyero cha titanium dioxide. Malo otentha a rutile titanium dioxide ndi (3200 nthaka 300) K, ndipo titaniyamu woipayo amasinthasintha pang'ono pa kutentha kwakukulu kumeneku.
Njira
Industrial titanium oxide sulfate imasungunuka m'madzi ndikusefedwa. Ammonia adawonjezeredwa kuti awononge mpweya wonga ngati gauntlet, kenako amasefedwa. Kenako imasungunuka ndi njira ya oxalic acid, kenako imatenthedwa ndikusefedwa ndi ammonia. Mpweya womwe wapezeka umawumitsidwa pa 170 ° C ndikuwotchedwa pa 540 ° C kuti mupeze titaniyamu wowona.
Ambiri aiwo ndi migodi yopanda dzenje. Titaniyamu primary ore beneficiation akhoza kugawidwa m'magawo atatu: Pre-kupatukana (nthawi zambiri ntchito maginito kulekana ndi mphamvu yokoka kulekana njira), chitsulo kulekana (maginito olekanitsa njira), ndi kulekana titaniyamu (mphamvu yokoka kulekana, maginito kupatukana, magetsi kulekana ndi njira flotation). Kupindula kwa titanium zirconium placers (makamaka oyika m'mphepete mwa nyanja, kutsatiridwa ndi oyika mkati mwa dziko) akhoza kugawidwa m'magawo awiri: kulekanitsa movutikira ndi kusankha. Mu 1995, Zhengzhou Comprehensive Utilization Research Institute of the Ministry of Geology and Mineral Resources inatengera njira ya kupatukana kwa maginito, kulekanitsa mphamvu yokoka ndi leaching ya asidi kuti ipindule ndi mgodi waukulu wa rutile ku Xixia, m'chigawo cha Henan, chomwe chadutsa kupanga, ndi zizindikiro zonse ali pa mlingo kutsogolera ku China.
ntchito
Amagwiritsidwa ntchito ngati spectral analysis reagent, kukonzekera mchere wambiri wa titaniyamu, ma pigment, polyethylene colorants, ndi abrasives. Amagwiritsidwanso ntchito m'makampani opanga mankhwala, capacitive dielectric, ma alloys osamva kutentha kwambiri, komanso kupanga siponji ya titaniyamu yosamva kutentha kwambiri.
Amagwiritsidwa ntchito popanga titaniyamu woipa, titaniyamu siponji, titaniyamu aloyi, yokumba rutile, titaniyamu tetrachloride, titaniyamu sulfate, potaziyamu fluorotitanate, zotayidwa titaniyamu kolorayidi, etc. Titaniyamu woipa angagwiritsidwe ntchito kupanga apamwamba kalasi woyera utoto, mphira woyera, ulusi kupanga , zokutira, ma elekitirodi owotcherera ndi ma rayon ochepetsa kuwala, mapulasitiki ndi mapepala apamwamba kwambiri, ndipo amagwiritsidwanso ntchito pazida zoyankhulirana, zitsulo, kusindikiza, kusindikiza ndi utoto, enamel ndi madipatimenti ena. Rutile ndiyenso mchere wopangira mchere woyenga titaniyamu. Titaniyamu ndi ma aloyi ake ali ndi zinthu zabwino kwambiri monga mphamvu yayikulu, kachulukidwe kakang'ono, kukana dzimbiri, kukana kutentha kwambiri, kukana kutentha pang'ono, kusakhala ndi kawopsedwe, ndi zina zambiri, ndipo ali ndi ntchito zapadera monga kuyamwa kwa gasi ndi superconductivity, motero amagwiritsidwa ntchito kwambiri ndege, makampani mankhwala, makampani kuwala, navigation, zachipatala, chitetezo dziko ndi chitukuko m'madzi ndi zina. Zoposa 90% za mchere wa titaniyamu padziko lapansi zimagwiritsidwa ntchito popanga utoto woyera wa titaniyamu, ndipo mankhwalawa amagwiritsidwa ntchito kwambiri popanga utoto, mphira, mapulasitiki, mapepala ndi mafakitale ena.
chitetezo
Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wokwanira. Phukusili ndi losindikizidwa. Sizingasungidwe ndikusakaniza ndi ma asidi.
Zogulitsa zamchere zamchere sizingasakanizidwe ndi ma sundries akunja pakupanga, kusungirako ndi kunyamula. Chikwama chopakiracho chimafunika kuti chisachite dzimbiri komanso chosavuta kusweka. Kupaka thumba lamitundu iwiri, zigawo zamkati ndi zakunja ziyenera kufananizidwa, mkati mwake ndi thumba la pulasitiki kapena thumba la nsalu (mapepala a kraft angagwiritsidwenso ntchito), ndipo wosanjikiza wakunja ndi thumba loluka. Kulemera konse kwa phukusi lililonse ndi 25kg kapena 50kg. Ponyamula katundu, pakamwa pa thumba payenera kutsekedwa mwamphamvu, ndipo chizindikiro cha m’thumbacho chiyenera kukhala cholimba, ndipo cholemberacho chiyenera kukhala chomveka bwino komanso chosazirala. Gulu lililonse lazogulitsa zamchere lizikhala limodzi ndi satifiketi yabwino yomwe imakwaniritsa zofunikira za muyezo. Kusungirako zinthu zamchere kuyenera kuyikidwa m'magulu osiyanasiyana, ndipo malo osungira azikhala oyera.
