Daim ntawv thov teb ntawm tungsten

Tungsten tseem hu ua wolfram, yog cov khoom siv tshuaj nrog lub cim ntawm W thiab tus lej atomic yog 74. Nws yog cov hlau tshwj xeeb uas muaj ntau yam siv tau hauv cov cuab yeej siv niaj hnub no. Tungsten hlau yog ib qho nyuaj thiab tsis tshua muaj hlau. Nws tsuas muaj nyob rau hauv lub ntiaj teb no nyob rau hauv chemical compounds. Feem ntau ntawm nws cov tshuaj sib txuas yog tungsten oxide thiab feem ntau ntawm cov tungsten mines tau pom nyob rau hauv Suav teb. Tshwj xeeb tshaj yog nyob rau hauv Hunan thiab Jiangxi xeev. Vim nws qhov siab melting point, siab hardness, zoo heev corrosion kuj, zoo hluav taws xob conductivity, thiab thermal conductivity, nws tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv kev lag luam niaj hnub no. Nws yog dav siv nyob rau hauv alloy, electronics, tshuaj, kev kho mob, thiab lwm yam teb.

1. Nyob rau hauv lub tshav pob ntawm Industrial alloys

Hmoov metallurgy yog txoj hauv kev tsim cov khoom tungsten sintered. tungsten hmoov yog cov khoom siv tseem ceeb tshaj plaws thiab qhov pib ntawm tungsten ntxhia khoom. Tungsten hmoov yog tsim los ntawm kev ci thiab cua sov tungsten oxide nyob rau hauv ib qho chaw hydrogen. Purity, oxygen, thiab particle loj yog qhov tseem ceeb heev rau kev npaj cov hmoov tungsten. Nws tuaj yeem sib xyaw nrog lwm cov hmoov hmoov los ua ntau yam tungsten alloys.

Tungsten carbide-raws li cemented carbide:

Tungsten carbide feem ntau yog siv los sib xyaw nrog lwm cov hlau los txhim kho nws cov kev ua tau zoo. Cov hlau sib xyaw muaj xws li cobalt, titanium, hlau, nyiaj, thiab tantalum. Qhov tshwm sim yog tias tungsten carbide-raws li cemented carbide muaj ntau dua hnav tsis kam thiab ntau dua refractory zog. Lawv tsuas yog siv hauv kev tsim cov cuab yeej txiav, cov cuab yeej mining, hlau kos duab tuag, thiab lwm yam. tungsten carbide-raws li cemented carbide cov khoom nyiam dua txawm tias cov hlau tsis muaj steel vim lawv qhov hardness zoo kawg thiab tsis kam hnav thiab tsim kua muag. Nws tuaj yeem siv dav hauv kev lag luam kev lag luam, khoom siv hluav taws xob, kev lag luam iav, cov khoom siv hluav taws xob tiv thaiv, thiab kev lag luam aeronautical.

Thaum tshav kub kub-resistant & hnav-resistant alloy:

Lub melting point ntawm tungsten yog qhov siab tshaj plaws ntawm tag nrho cov hlau, thiab nws hardness yog thib ob tsuas yog pob zeb diamond. Yog li nws yog feem ntau siv los tsim cov khoom kub-resistant thiab hnav-resistant alloys. Piv txwv li, Alloys ntawm tungsten thiab lwm yam hlau refractory (tantalum, molybdenum, hafnium) feem ntau tsim muaj zog qhov chaw xws li nozzles thiab cav rau foob pob ua ntxaij. Thiab cov alloys ntawm tungsten, chromium, thiab carbon feem ntau yog siv los tsim cov khoom muaj zog thiab hnav-tiv taus, xws li li qub rau lub tshuab dav hlau, lub log turbine, thiab lwm yam.

2. Hauv kev lag luam tshuaj

Tungsten compounds feem ntau yog siv los tsim qee hom xim, inks, lubricants, thiab catalysts. Piv txwv li, tooj liab-xim tungsten oxide yog siv rau hauv painting, thiab calcium los yog magnesium tungsten feem ntau yog siv nyob rau hauv phosphor.

3. Hauv kev ua tub rog

Cov khoom siv tungsten tau siv los hloov cov khoom siv lead ua thiab depleted uranium los ua cov mos txwv warheads vim lawv cov khoom tsis muaj tshuaj lom thiab tiv thaiv ib puag ncig, thiaj li txo cov pa phem ntawm cov khoom siv tub rog mus rau ecological ib puag ncig. Tsis tas li ntawd, tungsten tuaj yeem ua rau kev sib ntaus sib tua ntawm cov khoom siv tub rog zoo dua vim tias nws muaj zog hardness thiab zoo kub-resistant.

Tungsten tuaj yeem siv tsis tau tsuas yog hauv cov teb saum toj no nkaus xwb tab sis kuj tseem nyob hauv kev taw qhia, atomic zog, nkoj tsim, kev lag luam tsheb, thiab lwm yam. Yog tias koj txaus siab rau tungsten lossis muaj lus nug txog nws. Thov hu rau peb tam sim no.
