Hauv tsev kawm ntawv theem nrab, peb txhua tus tau kawm cov lus qhia hauv chav kawm chemistry: "Hydrogen, helium, lithium, beryllium, boron ... sulfur, chlorine, argon, potassium, calcium," thiabTitanium (Ti)yog lub ntsiab lus thib 22.
I. Keeb kwm ntawm Titanium
Xyoo 1791, tus txiv plig Askiv Askiv W. Gregor nrhiav tau ib qho khoom siv hlau tshiab.
Nyob rau hauv 1795, German chemist MH Klaproth kuj nrhiav tau lub caij no thiab muab nws lub npe tom qab Greek vajtswv, Titans.
Xyoo 1910, Asmeskas kws tshawb fawb MA Hunter yog thawj tus tsim cov titanium ntshiab los ntawm kev txo TiCl₄ nrog sodium.
Xyoo 1940, Luxembourg tus kws tshawb fawb WJ Kroll tau tsim cov titanium ntshiab los ntawm kev txo TiCl₄ nrog magnesium. Txij thaum ntawd los, cov txheej txheem txo magnesium (tseem hu ua Kroll txheej txheem) thiab cov txheej txheem txo sodium (tseem hu ua txheej txheem Hunter) tau dhau los ua cov txheej txheem kev lag luam rau kev tsim daim txhuam cev titanium.
II. Classification ntawm Titanium
Raws li cov ntsiab lus titanium, titanium tuaj yeem muab faib ua cov ntshiab titanium thiab titanium alloys. Ntshiab titanium feem ntau raug xaiv raws li Qib 1 (nrog cov ntsiab lus titanium ntawm 99.5% lossis siab dua), thaum titanium alloys ntxiv rau hauv - hom titanium alloys, - hom titanium alloys, thiab + - hom titanium alloys. Raws li lawv cov yam ntxwv ua tau zoo, lawv tuaj yeem muab faib ua cov txheej txheem titanium alloys, tshav kub-resistant (heat- zog) titanium alloys, thiab corrosion-resistant titanium alloys.
III. Qhov zoo ntawm Titanium
1. Low Density and High Strength: In many applications where weight is a critical consideration-such as the aerospace and construction industries-the use of titanium ensures structural stability while reducing overall weight and maintaining high strength. Qhov no pab txhim kho roj efficiency thiab payload muaj peev xwm nyob rau hauv aircraft.
2. Zoo heev -kub tsis kam: Titanium muaj qhov melting point siab txog 1,668℃thiab tuaj yeem tiv taus kev siv ntev ntawm qhov kub txog li 600℃yam tsis muaj kev qaug zog. Qhov no muab titanium zoo heev ruaj khov nyob rau hauv siab - kub khiav hauj lwm ib puag ncig, ua rau nws dav siv nyob rau hauv siab - cov khoom kub xws li aircraft cav thiab roj turbines.
3. Kev ua haujlwm kub zoo heev: Titanium khaws cia zoo ductility thiab toughness txawm nyob rau ntawm qhov kub thiab txias li -253 degree, zam qhov txias brittleness feem ntau txuam nrog hlau. Yog li ntawd, titanium kuj tsim nyog rau qhov kub thiab txias ib puag ncig thiab ua lub luag haujlwm tseem ceeb hauv kev siv xws li cov kua nitrogen cia thiab cov khoom siv thauj khoom, nrog rau cov khoom siv tshawb fawb txog kev tshawb fawb polar.
4. Kev tiv thaiv corrosion siab: Titanium nkag siab nrog cov pa oxygen hauv huab cua, tsim cov txheej tuab, muaj zog ntawm titanium dioxide ntawm nws qhov chaw. Cov oxide txheej no tiv thaiv oxidation ntxiv ntawm cov hauv paus titanium, cia nws nyob ruaj khov txawm nyob rau hauv ib puag ncig hnyav xws li muaj zog acids thiab alkalis. Piv txwv li, hauv kev lag luam tshuaj, titanium feem ntau yog siv los tsim cov khoom siv xws li reactors thiab cov kav dej, tiv thaiv corrosion los ntawm ntau yam xov xwm corrosive.
5. Zoo Biocompatibility: Titanium yog cov hlau tsis muaj - hlau nplaum uas tsis ua hlau nplaum. Nws muaj kev sib raug zoo nrog tib neeg cov ntaub so ntswg thiab cov ntshav, tsis yog - lom rau tib neeg lub cev, thiab tsis ua rau muaj kev phiv xws li kev ua xua lossis mob. Yog li ntawd, titanium yog siv dav hauv kev kho mob, piv txwv li, hauv kev tsim cov pob qij txha, kev cog hniav, thiab lub plawv stents.
6. Antimicrobial Properties: titanium ntim inhibits kev loj hlob ntawm cov kab mob; Cov kab mob phem tuag sai sai hauv ib puag ncig titanium, muab cov khoom titanium tshwj xeeb zoo hauv kev ua zaub mov, khaws cia, thiab kev siv tshuaj kho mob.
7. Environmental Friendliness: Titanium ua rau ib puag ncig muaj kuab paug tsawg thaum lub sijhawm tsim khoom thiab siv. Cov txheej txheem tsim khoom tsim cov khoom pov tseg me me, thiab cov khoom pov tseg titanium tuaj yeem siv thiab rov siv dua, ua tau raws li qhov yuav tsum tau muaj ntawm kev txhim kho kom ruaj khov.
8. Kev ua tau zoo heev: Titanium muaj qhov zoo ductility thiab machinability, tso cai rau nws los ntawm ntau yam txheej txheem xws li casting, forging, vuam, thiab 3D luam ntawv kom tau raws li qhov xav tau ntawm kev siv sib txawv.
