tungsten thiab molybdenum xaim Evaporation coils
Tungstenevaporation coils
Purity: W ≥ 99.95%
Cov xwm txheej ntawm qhov chaw: tshuaj ntxuav los yog electrolytic polishing.
Melt point: 3420 ± 20 ℃
Loj: raws li daim duab qhia.
Hom: Ncaj, U puab, V puab, Basket.Helical.
Daim ntawv thov: Tungsten hlau tso cua sov yog tsuas yog siv rau cua sov ntsiab xws li daim duab tube, daim iav, yas, hlau substrate, ABS, PP thiab lwm yam ntaub ntawv yas nyob rau saum npoo ntawm ntau yam khoom zoo nkauj. Tungsten hlau yog tsuas yog siv los ua raw khoom rau lub rhaub.
ua hauj lwm hauv paus ntsiab lus : Tungsten muaj lub siab melting point, siab hluav taws xob resistivity, zoo zog thiab tsawg vapor siab, ua rau nws haum rau siv raws li lub rhaub. Daim nyias nyias tau muab tso rau hauv lub rhaub dej hauv lub tshuab nqus tsev, thiab muab tso rau hauv lub tshuab nqus tsev siab los ntawm lub tshuab cua sov (tungsten rhaub) kom evaporate. Thaum txoj kev tsis pub dawb ntawm cov vapor molecules ntau dua li qhov loj me ntawm lub tshuab nqus tsev vacuum, cov atoms ntawm cov vapor tom qab cov molecules khiav tawm ntawm qhov chaw evaporation, lawv tsis tshua muaj kev cuam tshuam los yog cuam tshuam los ntawm lwm cov molecules lossis atoms, thiab tuaj yeem ncaj qha mus txog qhov chaw ntawm lub substrate kom plated. Vim qhov kub ntawm lub substrate yog qis, cov zaj duab xis yog tsim los ntawm condensation.
Thermal evaporation (kuj evaporation) yog txheej txheej siv los ua ib feem ntawm cov txheej txheem PVD (Lub Cev Vapor Deposition). Cov khoom uas yog tsim cov txheej tom ntej yog rhuab nyob rau hauv lub tshuab nqus tsev chamber kom txog thaum nws evaporates. Lub vapor tsim los ntawm cov khoom condenses ntawm lub substrate thiab tsim cov txheej yuav tsum tau.
Peb cov evaporation coils paub yuav ua li cas tig cov cua sov: Cov cua sov uas tsis muaj zog nrog lawv cov ntsiab lus melting siab heev yuav coj cov hlau mus rau qhov kub. Nyob rau tib lub sijhawm, lawv cov kev tiv thaiv corrosion siab thiab cov khoom zoo purity tiv thaiv kev kis kab mob ntawm cov substrate.
