Titanium (IV) oxyde CAS 13463-67-7 Intangiriro
ubuziranenge
Ifu yera ya amorphous. Hariho ibintu bitatu bya dioxyde de titanium ibaho muri kamere: rutile ni kristu ya tetragonal; Anatase ni kristu ya tetragonal; Isahani perovskite ni orthorhombic kristal. Umuhondo mubushyuhe buke nubururu mubushuhe bukomeye. Kudashonga mumazi, aside hydrochloric cyangwa acide nitric cyangwa kugabanya aside sulfurike na solide organic, gushonga muri acide sulfurike yibanze, aside hydrofluoric, gushonga gato muri alkali na acide ya nitric ishyushye. Irashobora gutekwa igihe kirekire kugirango ishonga muri acide sulfurike yibanze hamwe na aside hydrofluoric. Irakora hamwe na hydroxide ya sodium yashongeshejwe kugirango ikore titanate. Ku bushyuhe bwinshi, irashobora kugabanuka kuri titanium nkeya na hydrogène, karubone, sodium ya cyuma, nibindi, hanyuma igakora reaction ya karubone kugirango ikore titanium disulfide. Indanganturo ya dioxyde ya titanium nini nini muri pigment yera, naho ubwoko bwa rutile ni 8. 70, 2.55 kubwoko bwa anatase. Kubera ko dioxyde de anatase na plate byombi ihinduka rutile mubushyuhe bwinshi, ingingo zo gushonga no guteka za plate titanium na anatase mubyukuri ntizibaho. Gusa dioxyde ya rutile ifite aho ishonga kandi ikabira, aho gushonga kwa dioxyde ya rutile ni 1850 ° C, aho gushonga mu kirere ni (1830 isi 15) ° C, naho gushonga mukungahaza ogisijeni ni 1879 ° C. , kandi gushonga bifitanye isano nubuziranenge bwa dioxyde de titanium. Ingingo itetse ya dioxyde ya rutile ni (ubutaka 3200 300) K, na dioxyde ya titanium ihindagurika gato kuri ubu bushyuhe bwo hejuru.
Uburyo
Inganda ya titanium oxyde sulfate ishonga mumazi ikayungurura. Amoniya yongewemo kugirango igwe imvura imeze nkimvura, hanyuma irayungurura. Noneho irashonga hamwe na acide acide, hanyuma igwa hanyuma ikayungurura amoniya. Imvura yabonetse yumishijwe kuri 170 ° C hanyuma ikotsa kuri 540 ° C kugirango ibone dioxyde de titanium.
Benshi muribo ni ubucukuzi bw'amabuye y'agaciro. Inyungu yibanze ya Titanium irashobora kugabanywamo ibice bitatu: mbere yo gutandukana (bikunze gukoreshwa gutandukanya magnetique no gutandukanya imbaraga za rukuruzi), gutandukanya ibyuma (uburyo bwo gutandukanya magnetique), no gutandukanya titanium (gutandukanya imbaraga, gutandukanya magneti, gutandukanya amashanyarazi nuburyo bwo guhinduranya). Inyungu z'abashyira titanium zirconium (cyane cyane abashyira ku nkombe, bagakurikirwa n'abashyira imbere) barashobora kugabanywamo ibice bibiri: gutandukana bikabije no guhitamo. Mu 1995, Ikigo cy’ubushakashatsi cy’ubushakashatsi bwa Zhengzhou cya Minisiteri ya Jewoloji n’umutungo w’amabuye y'agaciro cyakoresheje inzira yo gutandukanya magnetiki, gutandukanya imbaraga hamwe no kwanduza aside kugira ngo bigirire akamaro ikirombe kinini cya rutile kiri i Xixia, mu Ntara ya Henan, cyatsinze umusaruro w’ibigeragezo, kandi ibipimo byose biri ku isonga mu Bushinwa.
Koresha
Ikoreshwa nk'isesengura ryerekana reagent, gutegura imyunyu ngugu ya titanium yuzuye, pigment, amabara ya polyethylene, hamwe na abrasives. Ikoreshwa kandi mu nganda zimiti, ubushobozi bwa dielectric, capacitif dielectric, amavuta arwanya ubushyuhe bwinshi, hamwe na titanium sponge ikora ubushyuhe bwinshi.
Ikoreshwa mu gukora dioxyde ya titanium, titanium sponge, titanium alloy, rutile artificiel, titanium tetrachloride, titanium sulfate, potassium fluorotitanate, aluminium titanium chloride, nibindi. , gutwikira, gusudira electrode hamwe na rayon igabanya urumuri, plastike hamwe nuzuza impapuro zo murwego rwohejuru, kandi nayo irakoreshwa mubikoresho byitumanaho, metallurgie, gucapa, gucapa no gusiga irangi, enamel nandi mashami. Rutile kandi nibikoresho byingenzi byibanze byo gutunganya titanium. Titanium n'ibiyikomokaho bifite ibintu byiza cyane nk'imbaraga nyinshi, ubucucike buke, kurwanya ruswa, kurwanya ubushyuhe bwinshi, kurwanya ubushyuhe buke, kutagira uburozi, n'ibindi, kandi bifite imirimo yihariye nko kwinjiza gaze no kurenza urugero, bityo bikoreshwa cyane muri indege, inganda zikora imiti, inganda zoroheje, kugendagenda, ubuvuzi, kurinda igihugu no guteza imbere umutungo w’inyanja nizindi nzego. Kurenga 90% by'amabuye y'agaciro ya titanium ku isi akoreshwa mu gukora ibara ryera rya titanium dioxyde, kandi iki gicuruzwa kirakoreshwa cyane mu gusiga amarangi, reberi, plastiki, impapuro n'inganda.
umutekano
Ubike mu bubiko bukonje, buhumeka. Ipaki irafunze. Ntishobora kubikwa no kuvangwa na acide.
Ibicuruzwa byamabuye y'agaciro ntibishobora kuvangwa nizuba ryinshi mugikorwa cyo gupakira, kubika no gutwara. Ibikoresho byo gupakira birasabwa kuba birwanya ruswa kandi ntibyoroshye kumeneka. Gupakira imifuka ibiri, ibice byimbere ninyuma bigomba guhuzwa, imbere imbere ni umufuka wa pulasitike cyangwa igikapu cyigitambara (impapuro zubukorikori nazo zishobora gukoreshwa), naho igice cyinyuma nigikapu kiboheye. Uburemere bwa buri paki ni 25kg cyangwa 50kg. Iyo upakira, umunwa wumufuka ugomba gufungwa cyane, kandi ikirango kiri mumufuka kigomba kuba gikomeye, kandi inyandiko yandikishijwe intoki igomba kuba isobanutse kandi ntigacike. Buri cyiciro cyibicuruzwa byamabuye y'agaciro bigomba guherekezwa nicyemezo cyiza cyujuje ibisabwa mubisanzwe. Ububiko bwibicuruzwa byamabuye y'agaciro bigomba gutondekwa mubyiciro bitandukanye, kandi aho bibikwa bigomba kuba bifite isuku.
