Elemental Titanium siv

Titanium thiab titanium alloys yog siv dav hauv kev lag luam aviation, hu ua "qhov chaw hlau"; Tsis tas li ntawd, muaj ntau yam kev siv hauv kev lag luam shipbuilding, tshuaj lom neeg kev lag luam, kev tsim cov khoom siv tshuab, khoom siv sib txuas lus, cemented carbide thiab lwm yam.

Vim tias titanium yog tawv thiab acid-resistant, nws yog siv nyob rau hauv ntau hom alloys. Cov xim dawb titanium dioxide (TiO2) npog rau saum npoo ntawm lwm cov ntaub ntawv uas muaj cov nyhuv zoo heev thiab siv rau hauv kev pleev xim, roj hmab, ntawv ua ...... thiab ntau lwm yam.

Nws siv ntau tshaj li ib puas xyoo los ntawm kev tshawb pom ntawm lub caij titanium mus rau kev tsim cov khoom ntshiab. Nws tsuas yog tom qab xyoo 1940s uas titanium tau siv tiag tiag thiab lees paub tias nws yog dab tsi.

Geographic nto ntawm kaum kilometers tuab txheej, titanium cov ntsiab lus ntawm rau txhiab, 6l lub sij hawm ntau tshaj tooj liab. Tsuas yog rub ib txhais tes ntawm cov av los ntawm hauv av, uas muaj ob peb txhiab ntawm titanium, lub ntiaj teb reserves ntawm ntau tshaj 10 lab tons ntawm titanium ore tsis tsawg.

Muaj ntau pua lab tons ntawm cov xuab zeb thiab pob zeb ntawm lub puam, titanium thiab zirconium ob hom minerals hnyav dua cov xuab zeb thiab pob zeb, sib xyaw hauv cov xuab zeb thiab pob zeb, tom qab ntau lab xyoo ntawm seawater hnub thiab hmo ntuj tsis nres, lub hnyav ilmenite thiab zirconium xuab zeb ore ntxuav ua ke, nyob rau hauv lub ntug dej hiav txwv ntev, tsim ib tug piece ntawm titanium thiab zirconium ore txheej. Cov txheej ntawm cov ore no yog cov xuab zeb dub, feem ntau yog ob peb centimeters mus rau kaum centimeters tuab.

Titanium tsis yog hlau nplaum, thiab nuclear submarines ua nrog nws tsis tas yuav txhawj txog cov mines sib nqus.

Nws tsuas yog xyoo 1947 uas tib neeg pib smelting titanium hauv cov chaw tsim khoom. Xyoo ntawd, tsuas yog 2 tons tau tsim, thiab xyoo 1955, ntau lawm tau nce mus rau 20,000 tons; xyoo 1972, kev tsim khoom tau mus txog 200, 000 tons hauv ib xyoos. Titanium lub hardness zoo ib yam li cov hlau, thaum nws qhov hnyav yog yuav luag ib nrab ntawm cov hlau hauv tib lub ntim. Txawm hais tias titanium yog me ntsis hnyav dua aluminium, nws hardness yog ob npaug ntau dua li ntawm txhuas. Hauv qhov chaw foob pob hluav taws thiab foob pob hluav taws, ntau tus titanium tsis siv hlau. Raws li kev txheeb cais, lub ntiaj teb txhua xyoo titanium siv hauv cosmic navigation, tau mus txog ntau tshaj ib txhiab tons. Zoo heev titanium hmoov, los yog foob pob ua ntxaij roj, yog li titanium yog lub npe hu ua lub ntug ntawm hlau, qhov chaw hlau.

Titanium cov cua sov kuj zoo heev, lub melting point ntawm mus txog 1725 degree. Nyob rau hauv chav tsev kub, titanium tuaj yeem pw tsis muaj mob hauv ntau yam kua qaub thiab alkali daws. Txawm tias cov kua qaub tshaj plaws, aqua regia, tsis tuaj yeem corrode nws. Titanium tsis ntshai dej hiav txwv, qee cov neeg tau poob ib daim titanium mus rau hauv qab dej hiav txwv, tsib xyoos tom qab coj los saib, sab saum toj ntawm cov tsiaj me thiab cov nroj tsuag seabed ntau heev, tab sis tsis muaj xeb. , tseem ci ntsa iab.
