titanium ua li cas? titanium ua li cas?
Titanium yog ib qho khoom siv hlau. Nws tau yeej lub koob npe nrov ntawm "qhov chaw hlau" rau nws cov khoom zoo heev thiab kev tiv thaiv corrosion. Nws muaj ntau yam kev siv hauv aerospace, khoom siv kho mob, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam. Yog li, ua li cas titanium tuaj ntawm ore thiab dhau los ua cov khoom muaj nqis hauv peb txhais tes ib kauj ruam? Cia peb nthuav tawm qhov paub tsis meej ntawm titanium manufacturing ua ke.
1. Ore hnav khaub ncaws
Kev tsim cov txheej txheem ntawm titanium pib nrog titanium ores zais tob hauv lub ntiaj teb crust. Titanium ores feem ntau muaj nyob rau hauv daim ntawv ntawm titanium dioxide, thiab cov uas nquag yog ilmenite thiab titanium vanadium ore. Hauv cov ore no, titanium muaj nyob rau hauv daim ntawv ntawm cov tebchaw, tos kom pom los ntawm tib neeg. Tom qab kev tshawb nrhiav thiab mining, cov ores no raug thauj mus rau smelters thiab pib lawv txoj kev zoo kawg nkaus ntawm kev hloov pauv mus rau hlau.
2. Ci
Nyob rau hauv lub smelter, titanium ore yuav ua ntej mus rau ib tug txheej txheem ntawm crushing thiab sib tsoo los ua hmoov zoo. Cov hmoov no ces xa mus rau qhov kub kub smelting rauv rau smelting. Nyob rau hauv qhov kub-kub smelting rauv, titanium keeb nyob rau hauv titanium ore reacts chemically nrog cov ntsiab lus xws li oxygen thiab carbon los tsim cov tebchaw xws li titanium oxide. Cov tebchaw no raug txo qis rau titanium hlau ntawm qhov kub thiab txias, tab sis cov titanium hlau nyob rau lub sijhawm no tseem sib xyaw nrog ntau yam impurities.
3. Kev huv huv
Cov txheej txheem purification feem ntau muaj xws li: Sputtering method: Siv lub zog ions los foob pob ntawm titanium hlau, tev tawm ntawm qhov chaw impurities, thiab tau txais cov hlau ntshiab titanium. Tshuaj vapor deposition txoj kev: Thaum tshav kub kub ntshiab titanium hlau mus rau ib tug high kub, react lub impurities nyob rau hauv cov roj nrog nws, thiab tso nws mus rau hauv ib tug khoom. Txhawm rau kom tau txais cov hlau ntshiab titanium, smelters siv txoj kev tshwj xeeb-electrolytic refining. Thaum lub sij hawm electrolytic refining txheej txheem, impure titanium hlau yog siv los ua anode, thiab ntshiab titanium hlau yog precipitated ntawm lub cathode. Los ntawm cov txheej txheem no, impurities nyob rau hauv titanium hlau yog maj mam muab tshem tawm, thiab ntshiab titanium hlau pib maj mam pib. Hauv kev tsim khoom, ntau yam khoom siv raw xws li txo cov neeg ua haujlwm, oxidizing agents, thiab fluxes kuj xav tau.
4. Kev ua haujlwm
Tom qab tau txais cov hlau ntshiab titanium, nws yuav tsum tau ua ntau yam kev ua thiab kev kho cua sov kom tau raws li cov kev xav tau ntawm cov ntaub ntawv sib txawv. Piv txwv li, los ntawm casting, forging thiab lwm yam txheej txheem, titanium hlau tuaj yeem ua tiav rau hauv ntau yam duab thiab specifications; los ntawm kev kho cua sov, lub koom haum qauv ntawm titanium hlau tuaj yeem hloov kho kom nws lub zog thiab corrosion kuj; kev tsim cov txheej txheem siv cov txheej txheem xws li forging los yog siab sib sau ua hlau titanium rau hauv cov duab uas yuav tsum tau ua.
5. Kev kho deg
Kev kho deg ntawm titanium yog ib qho tseem ceeb heev. Titanium muaj kev tiv thaiv corrosion zoo heev, tab sis nws qhov chaw feem ntau yuav tsum tau anodized, sandblasted, polished thiab lwm yam kev kho saum npoo los txhim kho nws qhov zoo thiab qhov tsos, thaum txhim kho nws cov corrosion kuj. cov
6. Kev sib dhos thiab kev sim ntawm titanium
Thaum kawg, kev sib dhos thiab kev sim ntawm titanium yog kauj ruam kawg hauv cov txheej txheem titanium. Cov khoom lag luam titanium semi-tiav uas tau ua tiav thiab kho saum npoo yog sib sau ua ke, xws li vuam, riveting, thiab lwm yam, thaum kawg tsim cov khoom tiav. Nyob rau tib lub sijhawm, cov khoom tiav tau raug soj ntsuam nruj me ntsis thiab kev tswj xyuas zoo kom ntseeg tau tias nws ua tau raws li cov qauv thiab cov kev cai, thiab xyuas kom meej tias cov khoom zoo yog ruaj khov thiab txhim khu kev qha. cov
Ntawm qhov tod tes, kev tsim cov titanium kuj yuav tsum xav txog kev tiv thaiv ib puag ncig thiab kev siv cov peev txheej, thiab siv txoj hauv kev xws li rov ua dua cov pov tseg kom txo tau qhov cuam tshuam rau ib puag ncig. Tom qab cov txheej txheem nyuaj no, ib qho zoo tib yam ntawm titanium ore yog thaum kawg hloov mus rau hauv cov khoom muaj nqis hauv peb txhais tes - titanium hlau.
