Coj koj mus rau qhov tsis paub meej ntawm tus nqi siab ntawm titanium daim txhuam cev, thiab vim li cas tom qab tus nqi siab ntawm titanium thiab titanium alloys?
Titanium, raws li muaj nuj nqis hlau, ib txwm khaws tus nqi siab, thiab lub hauv paus ua rau cov lus dag no hauv cov khoom siv kim kim - daim txhuam cev titanium. Titanium daim ntaub ntawv ua haujlwm ntau lawm yog qhov txuas yooj yim hauv titanium kev lag luam. Nws yog cov khoom siv raw rau titanium cov ntaub ntawv, titanium hmoov thiab lwm cov titanium Cheebtsam. Tig lub ilmenite mus rau hauv titanium tetrachloride, muab tso rau hauv ib lub tshuab kaw cia, sau nws cov hlau magnesium kom tau txais "daim txhuam cev titanium". Qhov no hom ntxeem tau "titanium daim txhuam cev" tsis tuaj yeem siv ncaj qha. Lawv yuav tsum tau melted mus rau hauv cov kua hauv cov hluav taws xob hluav taws xob ua ntej lawv tuaj yeem raug pov rau hauv Titanium Ingots.
Daim txhuam cev Titanium tsis yog tsuas yog cov khoom siv raw tseem ceeb rau kev tsim cov titanium thiab titanium alloys tab sis kuj tseem ceeb ntawm kev txiav txim siab lawv tus nqi. Yog li, vim li cas daim txhuam cev titanium yog li kim?
Titanium Daim Ntawv Qhia Tawm Ntawm Ob Leeg:
Rutile thiab ilmenite. Rutile yog daj rau liab-xim av ntxhia uas nplua nuj nyob rau hauv titanium dioxide (TiO2) thiab muaj qee qhov ntau ntawm cov hlau, niobium thiab tantalum. Ilmenite yog cov ntxhia nrog cov molecular molecular mis formula fetio3, uas cov theoretical cov ntsiab lus ntawm titanium dioxide yog 52%. Cov zaub mov no yauv ua cov txheej txheem nyuaj rau kev rho tawm titachium.
Cov txheej txheem ntau lawm ntawm titanium daim txhuam cev yog qhov tsis tshua muaj, xws li kev ua yeeb yam mining, txhawb nqa, ua kom sib haum, txo qhov distillation thiab lwm cov kauj ruam. Ntawm lawv, cov txheej txheem c chlorination yog cov kauj ruam tseem ceeb hauv kev ua titanium tetrachloride. Los ntawm kev txiav txim ntawm cov pa kub siab thiab chlorine roj, cov khoom siv titanium-nplua nuj reacts nrog cov carbonaceous txo tus neeg sawv cev los tsim titanium tetrachloride. Cov txheej txheem ua kom zoo yog siv los tshem tawm cov he-boiling point thiab qis-boiling point impurities nyob rau hauv titanium tetrachloride kom ntseeg tau tias qhov kev ua yeeb yam ntawm titanium. Distillation yog ib kauj ruam tseem ceeb hauv cov txheej txheem tsim khoom ntawm titanium daim txhuam cev. Nyob rau theem no, Titanium Pentachhloride yog rhuab rau siab thiab undergoes siv tshuaj lom neeg tsim cov tshuaj ntxuav tes rau titanium thiab tshuaj chlorine. Cov txheej txheem distillation yuav tsum tau ua kom meej tswj qhov kub thiab siab kom paub tseeb cov khoom lag luam zoo thiab ruaj khov. Hauv cov txheej txheem no, ua kom zoo rau cov khoom siv hluav taws xob hnyav nrog cov hlau hluav taws xob ntau dua los ntawm cov tshuab luam yeeb-xws li tshem tawm cov distillation kom tau txais ntshiab titanium. Cov txheej txheem hluav taws xob Magnesium yog ib qho ntawm cov kauj ruam tseem ceeb hauv kev ua cov kab xev titanium, uas tau siv los muab cov hlau nplaum hlau uas yuav tsum tau ua rau cov tshuaj tiv thaiv hlau. Thaum lub sijhawm tus txheej txheem no, cov tshuaj magnesium hluav taws xob yog electrolyzed rau hauv khw xim hlau magnesium thiab chlorine roj. Cov kauj ruam no ua lub luag haujlwm tseem ceeb hauv kev siv tshuaj lom neeg thaum lub sijhawm smelting.
Titanium daim txhuam cev yog qhov kim ib nrab vim tias nws cov khoom siv raw ntau lawm yog tsis muaj thiab nws cov txheej txheem refining yog cov nyom. Qhov kev txiav tawm thiab kev tsim cov nqi ntawm rutile thiab ilmenite yog siab, thiab lub tshuab nqus hluav taws xob yuav tsum muaj cov khoom siv hluav taws xob siab thiab ua kom muaj kev tsim kho cov nqi tsim khoom ntawm titanium daim txhuam cev. Ntawm qhov tod tes, muaj ntau cov kev siv roj ntsha hauv cov txheej txheem tsim khoom ntawm titanium daim txhuam cev, xws li cov teeb meem kev siv tshuaj kho mob, ua kom zoo dua thiab electrolysis. Kev tawg nyob rau hauv cov teeb meem txuj ci no xav tau ntau npaum li cas ntawm R & D thiab sijhawm.
Nyob rau hauv xyoo tsis ntev los no, nrog kev nce qib nruam ntawm titanium daim ntaub tawm ntau lawm, tus nqi ntawm titanium daim txhuam cev tau ua kom muaj qee qhov kev hloov pauv. Txawm li cas los xij, txawm tias tus nqi kuj muaj tsawg, tus nqi ntawm titanium daim txhuam cev tseem siab dua. Qhov no feem ntau yog vim muaj ntau lawm thiab ua kom zoo txheej txheem ntawm titanium daim txhuam cev tseem tsis yooj yim, thiab kev nce hauv lub zog nqi kuj tseem cuam tshuam nws tus nqi.
Kev lag luam khoom lag luam thiab thov kev sib raug zoo, qhov kev thov rau cov khoom siv titanium yog muaj zog heev, tshwj xeeb hauv lub zog, marine, lub zog tsim hluav taws xob thiab hluav taws xob lim dej4. Raws li thoob ntiaj teb xav tau rau cov ntaub ntawv kev ua haujlwm siab nce, kev lag luam ntawm titanium daim txhuam cev yog nruj me ntsis, uas ncaj qha tsav nws tus nqi.
Kev lag luam thoob ntiaj teb cov khoom lag luam, thoob ntiaj teb, tsuas muaj qee lub tebchaws muaj peev xwm tsim cov khoom siv titanium. Cov qauv no ua rau cov nqi lag luam thoob ntiaj teb ntawm titanium daim txhuam cev cuam tshuam los ntawm cov khoom siv thiab kev lag luam hauv kev ua lag luam thoob ntiaj teb thiab geopolitics
Txhawm rau kom paub txog, qhov tsis paub meej ntawm vim li cas lub titanium daim txhuam cev nyob rau hauv cov khoom siv raw rau nws cov khoom lag luam, qhov nyuaj ntawm cov txheej txheem ua kom zoo thiab muaj cov lag luam tawm. Cov xwm txheej tau sib koom ua ke rau tus nqi siab ntawm titanium daim txhuam cev, uas nyeg tau khaws cov nqi ntawm titanium thiab titanium alloys siab. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib nruam ntawm thev naus laus zis thiab txuas ntxiv tus nqi, tab sis nws txoj haujlwm tseem ceeb hauv kev tsim cov titanium thiab titanium alloys tseem yog iRSplaceable.
