Lub hauv paus ntsiab lus ntawm kev rwb thaiv tsev kub ntawm nano-ceramic qhov rais zaj duab xis yog nyob ntawm qhov kev xaiv spectral ntawm cov khoom ntawm nanoscale. Nws ua tiav kev tswj xyuas kom zoo thiab meej los ntawm kev siv lub cev ntawm kev nqus thiab kev xav, uas yog qhov txawv ntawm lub hauv paus ntsiab lus ntawm kev xav ntawm cov yeeb yaj kiab hlau.
1. Xaiv spectral absorption ntawm nanoparticles
Cov thev naus laus zis tseem ceeb nyob hauv kev tsim cov khoom siv ceramic rau hauv qhov loj me nanoparticles. Cov nanoparticles no muaj kev xaiv rau cov wavelengths sib txawv nyob rau hauv lub hnub ci spectrum: lawv muaj siab heev transmittance rau pom lub teeb (380-}780nm), ua kom pom tseeb; tib lub sijhawm, lawv muaj peev xwm nqus tau thiab hloov tau ze ntawm -infrared radiation (780-2500nm), uas nqa lub ntsiab ntawm cov cua sov. Tom qab nqus lub zog infrared, cov khoom nanoceramic hloov nws mus rau hauv qhov tsis muaj teeb meem microscopic vibrations lossis rov hluav taws xob, tsis yog ncaj qha coj mus rau hauv lub tsheb sab hauv.
2. Tsis yog -hlau reflection thiab lwm yam kub dissipation
Qee qhov siab -kawg nano-ceramic films kuj siv ntau- txheej nanostructures kom tsis yog- cuam tshuam nrog kev xav ntawm nruab nrab- thiab deb - infrared rays. Qhov kev xav no tsis tso siab rau cov txheej txheem hlau txuas ntxiv, yog li zam kev tiv thaiv electromagnetic. Ua ke nrog nws cov yam ntxwv nqus dej siab, qhov no tsim cov txheej txheem thermal rwb thaiv tsev zoo heev uas ua rau muaj qhov tseem ceeb ntawm kev nqus thaum ntxiv nrog kev xav, ua tiav qhov kawg hluav taws xob rwb thaiv tsev kev ua tau zoo nyob rau hauv cov xwm txheej ntawm lub teeb xa hluav taws xob.
3. Lub cev muaj zog thiab ruaj khov
Txij li cov txheej txheem yog lub cev nkaus xwb uas tso siab rau qhov ruaj khov kho qhov muag ntawm nanomaterial nws tus kheej, nws cov thermal rwb thaiv tsev kev ua tau zoo yuav tsis lwj thaum lub sij hawm xws li dyed films, thiab nws yuav tsis poob vim oxidation zoo li hlau films, yog li ua tau raws li thermal rwb thaiv tsev kev ua tau zoo nyob rau lub sij hawm.
