Titanium

Titanium, tshuaj cim Ti, atomic naj npawb 22, yog cov khoom hlau uas muaj nyob rau hauv pawg IVB ntawm lub rooj zaum.Lub melting point ntawm titanium yog 1660 ℃, lub boiling point yog 3287 ℃, thiab qhov ceev yog 4.54g / cm³.Titanium yog grey hloov hlau uas muaj lub teeb yuag, siab zog, thiab zoo corrosion kuj.Vim nws cov khoom siv tshuaj ruaj khov, ua haujlwm zoo rau qhov kub thiab txias, tsis tshua muaj kub, muaj zog acid thiab alkali, nrog rau lub zog siab thiab qhov ntom ntom, nws yog hu ua "qhov chaw hlau".Qhov sib xyaw ua ke ntawm titanium feem ntau yog titanium dioxide (feem ntau hu ua titanium dioxide).Lwm cov tshuaj muaj xws li titanium tetrachloride thiab titanium trichloride.Titanium yog ib qho ntawm cov khoom siv dav tshaj plaws hauv ntiaj teb, suav nrog 0.16% ntawm lub ntiaj teb crust, qeb thib cuaj.Lub ntsiab titanium ore yog ilmenite thiab rutile.Ob qhov zoo tshaj plaws ntawm titanium yog lub zog tshwj xeeb thiab muaj zog corrosion kuj, uas txiav txim siab tias titanium yog khi rau siv dav hauv aerospace, riam phom thiab khoom siv, lub zog, tshuaj lom neeg, metallurgy, kev tsim kho thiab kev thauj mus los thiab lwm yam.Cov nyiaj khaws cia ntau muab lub hauv paus rau kev siv dav ntawm titanium.

Cov qauv kev lag luam yog xav tau kev hloov kho sai sai

Tom qab kev loj hlob sai txij li lub xyoo pua tshiab, Tuam Tshoj lub peev xwm ntawm titanium sponge txhua xyoo tau mus txog 150,000 tons, thiab lub peev xwm ntawm titanium ingot tau mus txog 124,000 tons.Thaum lub sij hawm kev lag luam kev lag luam hauv tsev tau qeeb, qhov kev tsim khoom tiag tiag hauv xyoo 2014 yog 67,825 tons thiab 57,039 tons, kev khiav hauj lwm tus nqi tsis txaus, thiab cov lag luam feem ntau yog nyob rau hauv txoj hauj lwm ntawm cov khoom qis kawg, cov khoom convergence, kev sib tw hnyav, qis efficiency.Ntawm qhov tod tes, hauv aviation, kev kho mob thiab lwm yam khoom siv high-end kev tshawb fawb thiab kev tsim kho thiab kev tsim khoom, peb tsis tuaj yeem ua tau raws li kev xav tau ntawm cov khoom siv hauv tsev, aviation titanium alloy cov ntaub ntawv thiab cov ntaub ntawv kho mob titanium alloy thiab lwm yam khoom siv high-end titanium xav tau. yuav tsum tau import.Raws li qhov tshwm sim, Tuam Tshoj txoj kev lag luam titanium yog nyob rau hauv cov txheej txheem ntau ntxiv.Kev hloov kho ntawm titanium kev lag luam qauv thiab qhov teeb meem ntawm overcapacity yuav tsum tau daws los ntawm lub xeev, hauv zos thiab cov lag luam.
