Cov khoom siv evaporative txheej yog ib yam khoom siv los tso cov ntaub ntawv nyias nyias rau ntawm qhov chaw ntawm lub substrate, uas yog siv dav hauv cov khoom siv kho qhov muag, cov khoom siv hluav taws xob, cov txheej txheem zoo nkauj thiab lwm yam. Cov txheej txheej evaporative feem ntau siv qhov kub thiab txias los hloov cov khoom siv rau hauv lub xeev gaseous, thiab tom qab ntawd tso rau hauv lub substrate nyob rau hauv lub tshuab nqus tsev. Cov hauv qab no yog lub hauv paus ntsiab lus ua haujlwm ntawm cov khoom siv evaporative txheej:
Nqus ib puag ncig:
Kev ua haujlwm ntawm cov khoom siv txheej txheej evaporative yuav tsum tau ua nyob rau hauv qhov chaw nqus tsev siab kom tiv thaiv cov khoom los ntawm kev hnov mob nrog oxygen los yog lwm yam impurities hauv huab cua thaum lub sij hawm evaporation thiab xyuas kom meej qhov purity ntawm cov ntaub ntawv deposited.
Lub tshuab nqus tsev vacuum ua tiav qhov xav tau lub tshuab nqus tsev los ntawm cov khoom siv xws li cov twj siv tshuab thiab cov twj diffusion.
Evaporation qhov chaw:
Lub evaporation qhov chaw yog ib qho cuab yeej siv los ua kom sov thiab evaporate cov khoom txheej. Feem ntau evaporation qhov chaw muaj xws li cov cua kub tsis kam, electron beam evaporation qhov chaw thiab laser evaporation qhov chaw.
Resistance cua sov: cua sov cov ntaub ntawv los ntawm ib tug resistive hlau kom evaporate nws.
Electron beam evaporation: siv rab phom electron emit ib lub teeb hluav taws xob kom ncaj qha tshav kub cov khoom coated kom nws evaporate.
Laser evaporation: irradiate cov khoom nrog lub zog siab laser beam kom nws evaporate sai.
Cov txheej txheem evaporation:
Cov khoom siv coated yog hloov los ntawm cov khoom lossis cov kua hauv lub xeev mus rau lub xeev gaseous nyob rau hauv qhov kub ntawm qhov chaw evaporation, tsim vapor.
Cov vapor molecules no txav tau yooj yim nyob rau hauv ib qho chaw nqus tsev vacuum thiab diffuse nyob rau hauv tag nrho cov lus qhia.
Film deposition:
Vapor molecules ntsib qhov chaw txias ntawm lub substrate thaum lawv txav mus, condense thiab tso nyiaj los ua ib zaj duab xis nyias.
Lub substrate tuaj yeem tig los yog tsis sib xws rau qhov chaw vapor kom ntseeg tau tias muaj kev sib luag thiab sib xws ntawm zaj duab xis.
Cooling thiab Curing:
Tom qab tso tawm, zaj duab xis txias thiab kho rau ntawm qhov chaw substrate los tsim ib txheej txheej nyias nyias nrog cov khoom siv lub cev thiab tshuaj lom neeg.
Cov cheeb tsam ntawm daim ntawv thov
Optical Txheej: Siv los ua cov yeeb yaj kiab tiv thaiv kev cuam tshuam, tsom iav, cov ntxaij lim dej thiab lwm yam khoom siv kho qhov muag.
Cov khoom siv hluav taws xob: siv los tsim cov khoom sib xyaw ua ke, cov khoom siv semiconductor, cov khoom siv pom, thiab lwm yam.
Decorative coatings: siv rau saum npoo txheej ntawm decorations, watches, hniav nyiaj hniav kub, thiab lwm yam.
Cov txheej txheem ua haujlwm: siv los ua cov yeeb yaj kiab nrog cov haujlwm tshwj xeeb xws li tiv thaiv corrosion, tiv thaiv oxidation thiab hnav tsis kam.
Nrog nws cov purity siab, uniformity thiab multi-functionality, evaporative txheej tshuab tau dav siv nyob rau hauv ntau high-precision thiab high-thov daim ntaub ntawv.
