Kev tsim thiab siv titanium daim txhuam cev
Vim muaj cov tshuaj lom neeg ntau ntawm titanium hlau, nws tsuas yog muaj nyob rau hauv daim ntawv ntawm titanium dioxide thiab titanate nyob rau hauv cov xwm, thiab feem ntau coexists nrog cov ntsiab lus xws li hlau, calcium, magnesium, silicon, txhuas, manganese thiab tsawg ntiaj teb. Txhawm rau kom tshem tawm cov ntshiab titanium los ntawm cov ntxhia nyuaj no, peb yuav tsum mus dhau ntawm cov txheej txheem sophisticated ntws, thiab daim txhuam cev titanium yog cov khoom siv raw rau kev ua titanium.
Nyob rau hauv tus txheej txheem ntawm kev npaj daim txhuam cev titanium, magnesium txo qis-nqus distillation txoj kev occupies ib tug tseem ceeb txoj hauj lwm. Txoj kev no ua ntej yuav tsum muaj kev nplua nuj ntawm titanium minerals, thiab tom qab ntawd hloov lawv mus rau hauv titanium tetrachloride los ntawm cov txheej txheem chlorination. Tom ntej no, nyob rau hauv kev tiv thaiv ntawm argon, titanium tetrachloride txo nrog magnesium los tsim daim txhuam cev titanium. Los ntawm lub tshuab nqus tsev distillation, magnesium thiab magnesium chloride tuaj yeem sib cais ntxiv thiab tshem tawm, thiab thaum kawg tau txais daim txhuam cev ntshiab titanium khoom.
Daim txhuam cev titanium, raws li cov khoom siv tseem ceeb rau tag nrho cov khoom titanium tiav thiab titanium hmoov, nws qhov zoo yog qhov tseem ceeb rau kev ua haujlwm ntawm cov khoom titanium. Hauv kuv lub tebchaws, daim txhuam cev titanium muab faib ua 7 qib raws li tshuaj lom neeg muaj pes tsawg leeg thiab Brinell hardness, xws li 0A txog 5. Ntawm lawv, 0A thiab 0 qib sponge titanium muaj cov siab tshaj purity thiab yog siv nyob rau hauv high-end industrial thiab tub rog teb. Cov teb no muaj cov kev xav tau siab heev rau kev ua haujlwm ntawm cov khoom siv, tshwj xeeb tshaj yog nyob rau hauv kev lag luam aerospace, qhov chaw precision yuav tsum siv daim txhuam cev zoo titanium kom ntseeg tau tias lawv muaj kev nyab xeeb thiab kev ntseeg tau. Hauv kev kho mob, daim txhuam cev zoo titanium kuj tseem ua lub luag haujlwm tseem ceeb, xws li tib neeg cog thiab cov khoom siv phais. Lub biocompatibility thiab corrosion kuj ntawm cov khoom titanium no yuav tsum tau ua raws li cov qauv siab heev.
Qib 1 sponge titanium yog dav siv hauv aerospace, kev kho mob thiab kev ua kis las thiab chaw ua si. Hauv kev lag luam aerospace, nws yog siv los tsim cov khoom tseem ceeb xws li cov khoom siv cav thiab cov khoom siv fuselage ntawm cov dav hlau thiab foob pob hluav taws. Hauv kev kho mob, qib 1 sponge titanium yog siv los tsim cov khoom siv kho mob thiab khoom siv xws li pob qij txha thiab cov cuab yeej phais. Hauv kev lag luam kev ua si thiab kev lom zem, nws yog siv los tsim cov khoom siv ua kis las thiab cov khoom siv sab nraum zoov.
Rau cov teb uas tsis muaj purity yuav tsum, xws li kev lag luam tshuaj, ntsev thiab metallurgy, qib 2 thiab qib 3 sponge titanium feem ntau yog siv. Txawm hais tias cov sponge titanium no qis me ntsis hauv purity, lawv pheej yig dua thiab tuaj yeem ua tau raws li cov kev xav tau ntawm cov teb no rau cov ntaub ntawv titanium. Tus nqi ntawm qib 4 sponge titanium yog pheej yig dua thiab tsim nyog rau daim ntawv thov loj hauv kev lag luam tshuaj.
Txawm hais tias qhov purity ntawm qib 5 sponge titanium tsuas yog 98.5%, nws tsis tau txhais hais tias nws tsis muaj nqi ntawm daim ntawv thov. Hauv qee qhov chaw uas tsis tas yuav tsum muaj purity siab, xws li kev tsim kho, qib 5 titanium daim txhuam cev tau dhau los ua qhov kev xaiv zoo rau kev txo nqi thiab nce kev ua haujlwm zoo vim nws tus nqi qis thiab kev ua haujlwm txaus. Los ntawm rationally siv qib 5 titanium daim txhuam cev, tus nqi tsim kho tuaj yeem txo tau zoo yam tsis muaj kev cuam tshuam rau lub tsev zoo.
Hauv cov ntsiab lus, titanium daim txhuam cev ua lub luag haujlwm tseem ceeb hauv kev lag luam titanium hlau. Los ntawm high-end industrial teb mus rau kev siv lub neej txhua hnub, ntau qib ntawm titanium daim txhuam cev ua si lawv cov luag haujlwm tshwj xeeb thiab qhov tseem ceeb.
