Tungsten yog cov hlau tsis tshua muaj qhov sib txawv ntawm cov hlau. Nws lub siab melting taw tes, siab hardness, zoo heev corrosion, thiab cov hluav taws xob zoo ua rau nws muaj kev tiv thaiv hluav taws xob, kev tiv thaiv, thiab siab} Tech kev siv. Yog li, dab tsi yog cov ntawv thov tshwj xeeb ntawm tungsten?
1. Alloys
Hlau
Tungsten, vim nws lub siab hardness thiab ntom ntom, txhim kho txhim kho lub zog, hardness, thiab hnav tsis kam ntawm cov hlau. Nws yog qhov tseem ceeb ua ke keeb kwm thiab yog siv dav hauv kev tsim cov steel. Hom tungsten - muaj cov hlau muaj xws li hlau ceev, thiab tungsten {{} Cobalt sib nqus sib nqus hlau. Cov no yog feem ntau siv los tsim ntau yam cuab yeej, xws li hnyiab, milling cutters, thiab tuag thiab pwm pwm.
Tungsten carbide -} Raws li catented carbide
Tungsten carbide yog zoo li hnav - tiv taus uas ntawm pob zeb diamond, nrog kev sib dhos, nrog rau cov khoom siv ua kom zoo nkauj hauv kev ua kom carbides. Tungsten carbide- Raws li cov carbide: tungsten carbide {}}}}}}}} titanium Carbide - tantalum (niobium) carbide {{8 {{{9 {9 {9 {leth {9 { Cov no yog feem ntau siv nyob rau hauv kev tsim cov cuab yeej, cov cuab yeej tsuas yog, thiab xaim duab.
Hnav - ionistant alloys
Tungsten yog hlau refractory nrog lub siab yaj loj tshaj plaws (feem ntau saum 1650 degree) thiab siab hardness. Yog li ntawd, nws feem ntau yog siv los tsim cov cua sov- tsis kam thiab hnav {{}} tiv taus alloys. Piv txwv li, alloys ntawm tungsten nrog chungsten nrog chungal, thiab cov pa roj carbon {5} {Resistant seem xws li li qub thiab Turbine impellers nyob rau hauv lub dav hlau tshuab. Alloys ntawm tungsten nrog lwm cov hlau refract (xws li tantalum, niobium, thiab rhenium) feem ntau siv los tsim high {}} lub zog parts parts- muaj zog parts parts- muaj zog partszz {}} lub zog parts parts- muaj zog partszz {} Lub zog parts parts- lub zog parts parts- lub zog parts parts- muaj zog partszz {}} lub zog parts parts- lub zog parts parts- muaj zog partszz {}} lub zog parts parts- muaj zog partszz {} Lub zog kub}
Siab - Lub puab tsaig
Tungsten lub siab ntom thiab hardness ua nws ib cov khoom zoo rau kev tsim khoom siab siab - Lub puab tsaig alloys. Cov siab siab - Qhov ceev}}}}}}}} cu, thiab w {{10}-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} series, nyob ntawm lawv muaj pes tsawg leeg thiab daim ntawv thov. Vim lawv cov kev sib tsoo loj, lub zog thermal, siab siv hluav taws xob, thiab kev hloov hluav taws xob kub, thiab lwm yam kev siv hluav taws xob, thiab lwm yam kev siv.
Ii. Khoom siv hluav taws xob
Tungsten tau siv dav hauv cov khoom siv hluav taws xob thiab kev lag luam kev lag luam vim nws qhov kev ua kom zoo, thiab muaj zog electron muaj peev xwm. Piv txwv li, tungsten filaments muaj lub siab luminous zoo thiab lub neej ntev, ua rau lawv muaj teeb meem loj thiab tungsten- iodine teeb. Tungsten filaments tseem tuaj yeem siv los tsim cov yas ua kom sov thiab cov kab mob hluav taws xob roj, ntxiv rau cov tshuab cua sov hauv ntau cov twj paj nruag.
III. Tshuaj Kev Lag Luam
Cov tebcsten feem ntau siv nyob rau hauv kev tsim qee cov xim, pigments, inks, roj nplua nyeem, thiab catalysts. Piv txwv li, sodium tungstate feem ntau yog siv nyob rau hauv kev tsim cov hlau nyom, zoo li nyob rau hauv dungsten, nrog rau cov dyes, pigments, incloplating, thiab lwm yam .; Feem ntau cov acid feem ntau yog siv los ua cov mordant thiab zas xim rau kev lag luam textile, thiab raws li ib qho catalalists rau kev tsim cov khoom lag luam siab rau hauv kev lag luam tshuaj; Tus Disulfide feem ntau siv hauv cov khoom siv hluav taws xob hauv cev, xws li ua cov roj nplua nyeem thiab catalyst hauv kev tsim cov roj av ntau lawm; Bronze tungsten oxide yog siv rau hauv kev tha xim.
