CVD tube rauv (Chemical Vapor Deposition)-lub npe hu ua Chemical Vapor Deposition Tube Rauv- yog hom khoom siv thermal ua tau dav siv hauv cov khoom siv science thiab engineering. Nws cov kev siv tseem ceeb thiab kev ua haujlwm suav nrog:
Khoom loj hlob thiab Deposition:
Los ntawm kev qhia cov roj sib tov rau hauv lub qhov cub, CVD tube rauv ua kom yooj yim rau kev decomposition ntawm gases ntawm qhov kub thiab txias. Cov txiaj ntsig atoms lossis molecules tom qab ntawd tso rau hauv cov khoom siv substrate, yog li ua kom cov ntaub ntawv nyias, nanoparticles, thiab lwm yam khoom siv siab heev.
Thermal processing:
Ntxiv nrog rau cov khoom tso tawm, CVD tube rauv tuaj yeem ua haujlwm rau ntau yam kev kho cua sov-xws li hmoov calcination, ceramic sintering, siab -kev sim kub, thiab kev ua cov khoom siv dav dav- hla ntau yam khoom, suav nrog ceramics, hlau, electronics, iav, khoom siv tshuaj, khoom siv tshwj xeeb.
Nyias zaj duab xis npaj:
Qhov no suav nrog kev npaj cov yeeb yaj kiab hlau, semiconductor films, optical films, thiab cov ntaub ntawv zoo sib xws. Los ntawm kev tswj xyuas cov xwm txheej thiab cov khoom siv tau zoo, nyias - cov ntaub ntawv zaj duab xis muaj cov khoom tshwj xeeb thiab cov qauv tuaj yeem tau txais.
Kev npaj nanomaterial:
Lub cub tawg ua rau kev tsim cov khoom siv nano xws li nanoparticles thiab nanowires. Los ntawm kev kho cov tshuaj tiv thaiv kab mob thiab cov ntaub ntawv substrate, nanomaterials nrog ntau hom morphologies thiab qhov ntev tuaj yeem ua ke.
Kev lag luam semiconductor:
Hauv kev lag luam semiconductor,CVD tube furnacesua lub luag haujlwm tseem ceeb hauv cov txheej txheem tseem ceeb xws li nyias -film deposition, wafer tu, thiab kho deg.
Hmoov metallurgy:
Cov cuab yeej siv tau rau hauv thaj tsam ntawm cov hmoov hlau metallurgy, qhov uas nws yooj yim rau kev tsim cov khoom siv hlau lossis ceramic los ntawm cov pa roj- theem kev tshwm sim.
Kev npaj cov khoom siv kho qhov muag:
Nws tso cai rau cov synthesis ntawm pob tshab kho qhov muag cov ntaub ntawv, uas yog tom qab siv nyob rau hauv lub fabrication ntawm kho qhov muag pab kiag li lawm, optical coatings, thiab cov khoom zoo sib xws.
Tus Qauv Tsim:
Lub tshuab ua kom sov lub cev ntawm CVD tube rauv feem ntau nta ob - plhaub qauv.
Lub kiv cua txias yog nruab rau hauv cov kab noj hniav ntawm lub plhaub sab hauv thiab sab nrauv kom yooj yim rau cua sov thiab cua txias mus rau lub sijhawm kom ntseeg tau tias qhov kub thiab txias ntawm lub plhaub ntawm lub cub tawg tseem qis.
Lub cub tawg nws tus kheej feem ntau yog tsim los ntawm siab - cov ntaub ntawv purity (xws li siab -purity corundum).
Ob qhov kawg ntawm lub raj yog kaw siv siab - nqus stainless hlau flanges kom ntseeg tau tias roj- nruj thiab ruaj khov siab - kub tsis kam.
Temperature thiab Atmosphere Control:
Lub kaw lus muaj peev xwm tswj hwm qhov kub thiab txias ntawm huab cua hauv lub qhov cub kom ua tau raws li cov kev cai tshwj xeeb ntawm ntau yam ntaub ntawv thiab cov txheej txheem ua haujlwm.
Nws tau nruab nrog lub tshuab hluav taws xob txaus tswj hwm (xws li phau ntawv ntab ntws ntws los yog siab -cov tswj hwm qhov tseeb) kom ua tau raws li cov txheej txheem tshwj xeeb uas cuam tshuam nrog cov cua tiv thaiv sib txawv. High Efficiency thiab Kev txuag hluav taws xob:
Siv siab -kev ua tau zoo, lub zog- txuag hluav taws xob cov ntaub ntawv (xws li polycrystalline alumina fibers) los txhim kho kev siv hluav taws xob.
