Titanium yog dab tsi?

Titanium yog cov khoom siv tshuaj lom neeg nrog lub cim Ti thiab atomic tooj 22. Nws yog cov hlau uas muaj zog, hnav, thiab corrosion-resistant hlau uas feem ntau siv rau ntau yam kev siv. Titanium paub txog nws lub zog-rau-qhov hnyav piv, ua rau nws zoo tagnrho rau kev lag luam xws li aerospace, tub rog, kev kho mob, thiab cov khoom ua si. Nws kuj yog biocompatible, uas txhais tau hais tias nws tau txais txiaj ntsig zoo los ntawm tib neeg lub cev thiab feem ntau siv rau hauv kev kho mob cog thiab cov cuab yeej phais. Tsis tas li ntawd, titanium muaj kev tiv thaiv zoo heev rau kev xeb, txawm tias nyob rau hauv ib puag ncig nyuaj, ua rau nws yog qhov kev xaiv nrov rau kev siv marine thiab tshuaj ua haujlwm.

Titanium yog dab tsi?

Titanium yog tsim los ntawm cov txheej txheem hu ua Kroll txheej txheem, uas yog feem ntau txoj kev rau rho tawm titanium los ntawm nws cov ore. Nov yog ib qho kev piav qhia ntawm cov kauj ruam koom nrog hauv kev tsim cov titanium siv cov txheej txheem Kroll:

1. Ore Extraction: Titanium-muaj cov zaub mov xws li ilmenite, rutile, thiab titanite yog mined los ntawm lub ntiaj teb crust.

2. Hloov mus rau Titanium Tetrachloride (TiCl4): Cov titanium-muaj cov zaub mov raug ua tiav los ua titanium dioxide (TiO2). Tom qab ntawd TiO2 yog reacted nrog chlorine thiab carbon los tsim titanium tetrachloride.

3. Kev txo qis ntawm Titanium Tetrachloride (TiCl4): Lub titanium tetrachloride yog tom qab ntawd ua rau cov molten magnesium los yog sodium nyob rau hauv lub kaw reactor ntawm qhov kub thiab txias los tsim titanium hlau thiab magnesium los yog sodium chloride.

4. Kev tshem tawm cov impurities: Cov titanium daim txhuam cev uas tshwm sim tuaj yeem muaj cov impurities uas yuav tsum tau muab tshem tawm. Cov sponge yog tom qab ntawd ua tiav los ntawm ntau txoj hauv kev xws li lub tshuab nqus tsev arc remelting lossis electron beam melting los tsim cov titanium ntshiab.

5. Fabrication: Cov ntshiab titanium ingots tuaj yeem ua tiav los ntawm ntau txoj hauv kev xws li casting, forging, lossis machining los tsim cov khoom titanium rau ntau daim ntawv thov.

Qhov zoo ntawm Titanium:

1. High Strength-rau-Weight Ratio: Titanium muaj zog tshwj xeeb rau nws qhov hnyav, ua rau nws zoo tagnrho rau cov ntawv thov uas lub zog thiab lub teeb yuag yog qhov tseem ceeb.

2. Corrosion Resistance: Titanium nthuav tawm zoo heev tiv thaiv corrosion, txawm nyob rau hauv ib puag ncig hnyav xws li seawater thiab tshuaj ua cov nroj tsuag.

3. Biocompatibility: Titanium yog biocompatible thiab tsis muaj tshuaj lom, ua rau nws haum rau kev kho mob cog thiab cov cuab yeej phais.

4. High-Temperature Resistance: Titanium tuaj yeem tiv taus qhov kub thiab txias yam tsis poob nws lub zog, ua rau nws tsim nyog rau kev siv hauv aerospace thiab kev lag luam.

5. Tsawg Thermal Expansion: Titanium muaj qhov coefficient qis ntawm thermal expansion, ua rau nws ruaj khov nyob rau hauv qhov kub thiab txias.

Qhov tsis zoo ntawm Titanium:

1. Tus nqi: Titanium yog kim dua li ntau lwm yam hlau, feem ntau vim nws txoj kev rho tawm thiab ua cov txheej txheem.

2. Nyuaj hauv Machining: Titanium paub txog nws qhov kev ua haujlwm tsis zoo, xav tau cov cuab yeej tshwj xeeb thiab cov txheej txheem rau kev txiav thiab shaping.

3. Sensitivity to Contamination: Titanium rhiab heev rau kev sib kis thaum ua, uas tuaj yeem cuam tshuam rau nws cov khoom thiab kev ua haujlwm.

4. Lower Modulus ntawm Elasticity: Titanium muaj qhov qis dua ntawm elasticity piv rau cov hlau, uas tuaj yeem txwv nws cov ntawv thov hauv qee qhov kev ntxhov siab.

5. Reactivity ntawm Kub Kub: Titanium tuaj yeem cuam tshuam nrog qee cov ntaub ntawv ntawm qhov kub thiab txias, yuav tsum tau ceev faj hauv cov ntawv thov tshwj xeeb.
