Dab tsi yog xim ntawm Titanium, Dab tsi yog nws cov khoom thiab kev ua haujlwm

Cov yam ntxwv ntawm titanium

Titanium yog cov nyiaj-grey hlau, mos thiab malleable. Melting point 1660 degree, boiling point 3287 degree, ceev 4.5g / cm3. Tsis zoo hluav taws xob thiab thermal conductivity. Titanium tuaj yeem tsim cov alloys nrog ntau cov hlau thiab ntau yam tsis yog hlau. Lub zog ntawm titanium alloy tuaj yeem nce ntxiv los ntawm kev ntxiv lwm cov hlau rau nws. Lub zog ntawm titanium alloy muaj zog dua li ntau cov hlau alloy.

Titanium muaj kev tiv thaiv corrosion zoo heev. Nyob rau hauv chav tsev kub, ib tug tiv thaiv oxide zaj duab xis yog yooj yim tsim nyob rau saum npoo ntawm titanium hlau. Nws tsis yog eroded los ntawm dej, nitric acid, dilute sulfuric acid, dilute hydrochloric acid thiab dilute alkali daws, thiab muaj ib tug tshwj xeeb muaj zog corrosion kuj rau seawater. Hydrofluoric acid, phosphoric acid thiab nruab nrab lub zog alkali muaj corrosive nyhuv ntawm titanium.

Thaum kub kub titanium tuaj yeem ncaj qha ua ke nrog cov khoom tsis yog hlau, xws li hydrogen, oxygen, nitrogen, carbon, sulfur thiab halogen. Titanium yog qhov thib cuaj tshaj plaws nyob rau hauv lub ntiaj teb crust ntawm 0.6 feem pua ​​.

Ib qho ntawm kev siv titanium

Titanium muaj cov yam ntxwv ntawm qhov ntom ntom ntom ntom, cov kub ua tsis kam thiab corrosion tsis kam. Titanium alloy siab zog, muaj coob tus siv nyob rau hauv kev tsim cov tub rog supersonic aircraft structural Cheebtsam, kuj siv nyob rau hauv lub tsim ntawm foob pob ua ntxaij cav vaj tse, dag satellite vaj tse, tab sis kuj yuav siv tau los tsim ships thiab submarines ntawm ntau yam. Titanium alloy yog siv los ua phom, tso tsheb hlau luam, thiab lwm yam, uas tuaj yeem txo qhov hnyav thiab ruaj khov. Titanium feem ntau yog siv rau hauv kev tsim tshuaj los ua cov khoom siv hluav taws xob thiab hauv kev lag luam hluav taws xob ua deoxidizer. Titanium tsis muaj tshuaj lom rau tib neeg thiab tsis hnov ​​​​tsw ntawm tib neeg cov leeg thiab pob txha, yog li nws paub txog kev kho mob li "biometallic". Yog li ntawd, nws yog dav siv los ua cov cuab yeej kho mob thiab cov khoom siv dag zog sib koom ua ke, dag lub plawv valve, cov hniav cuav thiab lwm yam. Qhov kev thov rau titanium tau nce thoob ntiaj teb hauv xyoo tas los no. Paub tias yog lub xyoo pua 21st hlau. Titanium ore cov peev txheej muaj ntau nyob hauv Suav teb.

Qhov thib ob siv titanium

Titanium muaj lub siab melting point, tsawg ntom, siab mechanical zog, thiab yog ib qho yooj yim rau txheej txheem thiab tsim, thiab muaj zoo heev corrosion kuj. Titanium thiab titanium alloys tuaj yeem tswj tau lawv cov khoom siv kho kom zoo ntawm qhov kub thiab txias.

Titanium thiab titanium alloys tau siv dav vim tias cov khoom zoo tshaj plaws saum toj no.

Hauv kev lag luam hlau, titanium - tungsten carbide yog siv los ua cov cuab yeej txiav, txiav hlau.

Hauv kev lag luam aviation, titanium thiab titanium alloys yog siv los ua cov tshuab dav hlau thiab dav hlau fuselages. Hauv kev lag luam foob pob hluav taws, missile thiab aerospace kev lag luam, nws yog tsuas yog siv raws li cov hlab ntsha siab, roj tso tsheb hlau luam, foob pob hluav taws cav plhaub, foob pob hluav taws nozzle lub tes tsho, cov khoom siv satellite plhaub, lub dav hlau cabins, thiab lwm yam.

Hauv kev tsim nkoj, siv los ua cov plhaub rau cov nkoj hiav txwv thiab cov nkoj

Hauv kev lag luam chemical, nws yog siv los tsim ntau yam khoom siv tshuaj xws li cov khoom siv hluav taws xob, cov twj tso kua mis, cov reactors, cov cua sov, thiab lwm yam.

Nws yog siv los ua cov khoom siv desalination hauv seawater desalination systems.

Tsis tas li ntawd, titanium hauv kev lag luam metallurgical, cov khoom siv hluav taws xob thiab cov khoom siv sib txuas lus, kev kho mob ntxiv, kev lag luam ntawv thiab kev lag luam pigment, muaj ntau yam kev siv. Piv txwv li, vim tias nws lub zog qis thiab siab lub zog, titanium yog yooj yim yoog los ntawm cov khoom siv kho mob ntxiv, yog li nws feem ntau siv los hloov cov pob txha ua kom puas hauv tib neeg lub cev. Titanium dioxide feem ntau yog siv los ua cov khoom siv hauv kev lag luam ntawv, ntxiv titanium dawb daim ntawv dawb, muaj zog luster, nws opacity dua nrog calcium carbonate thiab lwm yam zoo tib yam muab tub lim txog kaum zaus siab dua. Titanium dioxide muaj lub zog npog loj, kev ploj mus tas li ntawm cov hluavtaws fibers, thiab yuav tsis txo lub zog ntawm cov fiber ntau, yog ib qho zoo muab tub lim. Qhov sib ntxiv ntawm titanium dioxide rau ceramics thiab enamels txhim kho lawv cov kua qaub.

Txawm hais tias titanium muaj ntau yam khoom zoo heev, nws qhov kev nyiam thiab kev siv tseem txwv vim qhov nyuaj ntawm smelting thiab tus nqi siab.

Qhov zoo tshaj ntawm titanium

Tam sim no titanium hu ua "21st caug xyoo hlau" vim li cas?

Muaj tsawg kawg yog ob qho laj thawj: ntawm ib sab, titanium muaj ntau yam khoom zoo heev; Lwm qhov laj thawj yog tias titanium muaj ntau nyob rau hauv lub ntiaj teb lub pob zeb. Xyoo 1910, lub ntiaj teb kev tsim cov titanium txhua xyoo tsuas yog 0.2g! Los ntawm 1947, nws tau nce mus rau ob tons; Xyoo 1955, nws tau nce mus rau 20,000 tons; Los ntawm 1962, nws tau dhia mus rau 100, 000 tons! Ob peb xyoos dhau los, titanium tau muab cais ua "tsis tshua muaj hlau." Ua tib zoo tshawb nrhiav los ntawm geochemists, txawm li cas los xij, tau pom tias titanium muaj ntau nyob rau hauv lub ntiaj teb lub pob zeb ntau dua li cov hlau xws li tooj liab, tin, manganese, thiab zinc, thiab nyob qib xya hauv ntiaj teb tom qab txhuas, hlau, calcium, sodium, potassium, thiab magnesium. .

Kev ua tau zoo ntawm titanium yog qhia hauv cov hauv qab no:

(1) Lub zog zoo. Lub zog ntawm titanium alloy yog 2 ~ 3 npaug ntawm txhuas thiab 5 npaug ntawm magnesium. Nws tseem muaj zog dua li ntau cov hlau alloy. Thaum rhuab mus txog 673K, lub zog ntawm magnesium, txhuas thiab lwm yam hlau raug txo kom tsawg, thaum lub zog ntawm titanium alloy hloov me ntsis. Thaum lub dav hlau ceev tshaj 2.2 npaug ntawm qhov ceev ntawm lub suab, qhov kev sib txhuam hnyav ntawm lub dav hlau daim tawv nqaij thiab huab cua tsim kom muaj qhov kub thiab txias, aluminium alloy tsis tuaj yeem tiv taus. Titanium alloys tau coj lawv qhov chaw.

(2) Lub rigidity ntawm titanium rigidity yog ntau dua li ntawm txhuas thiab magnesium. Nws elastic coefficient yog hais txog ib nrab ntawm cov hlau, tab sis ntau loj dua txhuas thiab magnesium.

(3) Qhov ceev ntawm lub teeb titanium tsuas yog 4.54g / cm3, uas yog ib nrab ntawm qhov ntom ntawm cov hlau, yog li qhov loj ntawm titanium ntawm tib qhov loj yog sib dua li cov hlau. Titanium yog siv nyob rau hauv kev tsim aircraft, tsis tsuas yog txo qhov hnyav ntawm lub dav hlau lawv tus kheej, tab sis kuj nqa hnyav dua thiab ya sai.

(4) Lub zog / qhov hnyav piv Titanium muaj lub zog loj tshaj plaws / qhov hnyav ntawm ib qho hlau. Ntawd yog, titanium yog cov khoom siv hlau hnyav tshaj plaws ntawm tib lub zog.

(5) Corrosion tsis kam rau cov neeg ua haujlwm corrosive, titanium corrosion kuj thiab stainless hlau, tib yam corrosion kuj rau seawater thiab platinum, vim hais tias nyob rau hauv cov huab cua, titanium nto sai tsim ib txheej tuab heev ruaj khov titanium oxide zaj duab xis, tiv thaiv sab hauv. los ntawm corrosion. Yog li nws tau dhau los ua cov khoom siv zoo rau kev tsim cov nkoj thiab cov nkoj hauv nkoj.

Vim yog cov khoom zoo heev, titanium muaj ntau yam kev siv hauv kev tshawb fawb thiab thev naus laus zis niaj hnub no. Cov hlau titanium kuj muaj kev siv tshwj xeeb hauv cov tshuaj ua "biomimetic" vim nws muaj peev xwm hloov cov pob txha puas.

Tuam Tshoj cov khoom siv titanium yog qhov zoo, titanium nyob rau hauv txhua yam ntawm daim ntawv thov ntau dua.
