Yuav tungsten yuav tau sib xws nrog cov hlau tsawg? Vim li cas?

Lub tungstenyog qhov tsawg thiab siab melting taw tes hloov cov khoom siv hlau thiab tshuaj lom neeg {}} lub cim qhia yog li 34 ± 20 degree, uas yog qhov siab tshaj plaws ntawm txhua tus kav hlau,

Cov yam ntxwv ntawm Tupsten:

Hardness Hardness: Tungerten muaj lub siab tawv, feem ntau yog saum hrc 60, thiab txawv nrog qib carbonization thiab huv si .

Kev ceev faj: Qhov ntom ntawm tungsten yog li 19 {{{{{{1 g / cm ³, ua rau nws haum rau siv raws li qhov hnyav lossis cov khoom tiv thaiv.

Kev ua haujlwm zoo thiab thermal conductivity: txawm hais tias tsis zoo li tooj liab lossis cov nyiaj siv tau tseem muaj kev ua haujlwm zoo ntawm qhov kub thiab txias {}}

Corrosion Kuj: Tungsten tsis yooj yim corroded los ntawm cov acids thiab cov hauv paus, muaj qhov tsim nyog siv tshuaj ruaj khov, thiab haum rau siv nyob rau hauv cov chaw hnyav .

Tsawg Vapor Siab: Thaum muaj qhov kub qis, tungsten muaj cov vapor tsawg heev, ua rau nws cov khoom siv uas nyiam rau lub tshuab nqus tsev thiab kub siab}

Ib qho yooj yim rau daim tawv muaj zog: Tungsten thiab Carbon tuaj yeem tsim cov khoom siv tsis tshua muaj zog tungsten carbide, uas yog qhov tseem ceeb ntawm kev tsim cov cuab yeej thiab hnav-resistant seem {}}

Chaw Thov:

Vim nws lub cev thiab tshuaj lom neeg tshwj xeeb, tungsten muaj ntau cov kev siv hauv ntau thaj teb:

Kev kub siab cov thev naus laus zis: lub siab melting taw tes thiab kub kub lub zog ntawm tungsten ua rau nws yog ib qho tseem ceeb ntawm kev tsim khoom ntawm cov cua sov, lub zog, thiab sib txuas ntawm.

Txiav cov cuab yeej thiab cov pwm: lub siab tawv thiab hnav tsis kam ntawm kev tsim cov cuab yeej, kev sib tsoo thiab roj drilling kev lag luam .

Cov khoom siv hluav taws xob: Qhov kev ua haujlwm zoo thiab thermal conductivity ntawm tungsten ua nws tseem ceeb rau cov kev lag luam hauv lub teeb hlau, xws li high-kub alloys.

Kuj tseem siv tau cov khoom siv kub, Tungsten tseem siv los tsim cov khoom siv tiv thaiv thiab cov khoom cuav {}}

Cov ntawv thov tshwj xeeb ntawm cov tungsten sib sau alloys nrog lwm cov hlau:

Cov yam ntxwv alloys: tungsten tau siv dav hauv ob npib tshwj xeeb, thiab hnav-des resistant alloys, thiab cov roj av ua cov nroj tsuag, thiab lwm yam {}

Vuam thiab nplaim Hardening Alloys: Los ntawm ntau cov kev sib tsoo ntawm cov hlau uas muaj kev sib tsoo thiab cov pob zeb ua kom tsis txhob muaj kev sib tsoo thiab kev lag luam English.

Kev hnyav: Feem ntau muaj tshaj li 90% tungsten, nrog cov khoom siv tooj liab thiab cov npe ntawm lub cev hnyav, hnyav thiab zoo li qub thiab zoo li qub}

Refractory Alloy: Tungsten tuaj yeem tsim cov kuab txheej alloy nrog lub zog loj thiab tantalum thiab tantalum, txhim kho qhov kev ua tiav yog tias nws ntau tshaj li kev faib ua ntej.

Hlau tungsten Infiltration: xws li tooj liab lossis nyiaj tungsten alloy, siv los ua cov khoom siv hluav taws xob, nrog arc zoo heev thiab kev coj zoo.

Txawm hais tias tungsten yog lub luag haujlwm tseem ceeb hauv cov hlau tsis tshua muaj, yog li cov hlau tsis tshua muaj, feem ntau yog ua rau muaj cov hlua khi, feem ntau, cov roj ntsha, thiab txhuas, thiab txhuas, zoo li tantalum, rhenium, thorium, thiab zirconium .
