Tungsten filament hlauyog cov cua kub hlau ua los ntawm tungsten, feem ntau siv hauv cov qhov muag teeb hauv cov khoom siv teeb pom kev zoo. Tungsten muaj qhov siab melting point thiab corrosion kuj, uas tuaj yeem tiv taus qhov kub thiab txias thiab siv mus ntev. Hauv cov khoom siv teeb pom kev zoo, tungsten filaments yog rhuab mus rau qhov kub siab heev, uas tawm lub teeb pom kev. Vim yog cov conductivity thiab stability ntawm tungsten hlau, nws kuj yog dav siv nyob rau hauv lwm yam teb uas yuav tsum tau cua sov, xws li radiators, ncu, thiab hluav taws xob soldering irons.

1. Lub cev muaj zog

1) Siab melting point: Lub melting point ntawm tungsten yog 3410 degree, uas yog siab tshaj ntawm tag nrho cov hlau.

2) High Density: Qhov ceev ntawm tungsten yog 19.2 g / cubic centimeter, uas yog siab tshaj plaws ntawm tag nrho cov hlau.

3) Lub zog siab: Tungsten muaj lub zog zoo heev thiab hardness, thiab tuaj yeem tswj xyuas cov khoom zoo ntawm qhov kub thiab txias.

4) Corrosion kuj: Tungsten muaj kev ruaj ntseg siab thiab tuaj yeem nyob ruaj khov rau lub sijhawm ntev hauv oxidizing cua, acid-puag ib puag ncig thiab kub siab.

2. Cov khoom siv tshuaj

1) Tsis yooj yim rau oxidized: tungsten muaj peev xwm redox siab, thiab nws yog ib qho yooj yim los tsim ib tug ruaj khov tungsten oxide zaj duab xis los tiv thaiv tungsten hlau los ntawm oxidized.

2) Zoo corrosion kuj nyob rau hauv muaj zog acid thiab muaj zog alkali: tungsten tuaj yeem nyob ruaj khov hauv cov kua qaub thiab muaj zog alkali rau lub sijhawm ntev, thiab tsis yooj yim rau corrode.

3) Tsis yooj yim rau tawg los ntawm electrons: Tungsten muaj hluav taws xob emission efficiency thiab tsis yooj yim rau tawg los ntawm electrons

4) Cov thermal expansion coefficient me me: Tungsten muaj cov thermal expansion coefficient me me thiab tuaj yeem tswj cov qauv ruaj khov ntawm qhov kub thiab txias.

Feem ntau hais lus, tungsten hlau muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, oxidation tsis kam, corrosion kuj, thiab siab zog, thiab yog cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob thiab lub teeb.

3. Cov txheej txheem tsim khoom

Tungsten filament hlau yog ib yam khoom siv los ua qhov muag teeb. Nws cov txheej txheem ntau lawm suav nrog cov kauj ruam hauv qab no:

Xaiv cov khoom siv tungsten zoo thiab ua kom sov rau lub xeev kub.
Cov khoom siv tungsten yog kos rau hauv filaments siv lub tshuab nqus hlau.
Tom qab tungsten hlau nto kho thiab qhov cub ci, tungsten filament muaj lub cev zoo dua thiab tshuaj lom neeg.

4. Txoj Cai Ua Haujlwm

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tungsten filament hlau yog tias thaum hluav taws xob tam sim no dhau los ntawm tungsten filament, tungsten filament yuav sov. Raws li qhov tam sim no nce, qhov kub ntawm tungsten hlau yuav maj mam nce, thiab thaum kawg ncav cuag qhov kub thiab txias ntawm cov filament. Qhov kub ntawm tungsten filament feem ntau ncav cuag ntau tshaj 2000 degrees Celsius, uas ua rau lub teeb lub teeb ci ci ci ci.

5. Daim ntawv thov teb

Tungsten filament filaments yog dav siv nyob rau hauv ntau yam teeb pom kev zoo, cua sov, cov khoom siv nqus tsev vacuum thiab cov khoom siv hluav taws xob thiab lwm yam. Nws muaj cov khoom zoo xws li lub zog siab, siab melting point, thiab siab corrosion kuj, thiab nws ua tau zoo nyob rau hauv hnyav ua hauj lwm ib puag ncig xws li kub, siab siab, thiab muaj zog vibration.
