Lub teeb infrared muaj qhov cuam tshuam thermal, uas yooj yim ua rau qhov kub thiab txias.Ordinary architectural iav tsis muaj hluav taws kub rwb thaiv tsev uas tuaj yeem ua tiav los ntawm txoj kev xws li kev ua yeeb yaj kiab.Yog li ntawd, qhov saum npoo ntawm cov iav vaj tse, lub tsheb zaj duab xis, cov chaw sab nraum zoov, thiab lwm yam yuav tsum tau siv cov khoom siv hluav taws xob rwb thaiv tsev kom ua tiav cov nyhuv ntawm cov rwb thaiv tsev kub thiab txuag hluav taws xob.Nyob rau hauv xyoo tas los no, tungsten oxide tau nyiam cov neeg nyiam thoob plaws vim nws cov khoom siv hluav taws xob zoo heev, thiab cesium-doped tungsten oxide hmoov muaj cov yam ntxwv nqus tau zoo heev hauv cheeb tsam infrared, thiab tib lub sijhawm, pom lub teeb xa tawm siab.Cesium tungsten bronze hmoov yog tam sim no ib tug inorganic nano hmoov nrog qhov zoo tshaj plaws nyob ze-infrared nqus peev xwm, raws li ib tug pob tshab thaum tshav kub kub rwb thaiv tsev cov ntaub ntawv thiab ib tug ntsuab zog-txuag thiab ib puag ncig tus phooj ywg cov ntaub ntawv, nws muaj ib tug ntau yam ntawm daim ntawv thov kev cia siab nyob rau hauv thaiv infrared, iav tshav kub. rwb thaiv tsev thiab lwm yam tsheb thiab cov tsev.

Nano cesium tungsten bronze,Tom ntej: Cesium-doped tungsten oxide Cs0.33WO3Tsis tsuas yog muaj zog nqus cov yam ntxwv nyob rau hauv ze-infrared cheeb tsam (wavelength ntawm 800-1100nm), tab sis kuj muaj zog kis tus yam ntxwv nyob rau hauv lub pom teeb pom kev zoo cheeb tsam (wavelength ntawm 380-780nm), thiab nyob rau hauv lub ultraviolet cheeb tsam (wavelength ntawm 200-380nm). ) kuj muaj cov yam ntxwv tiv thaiv zoo.

Kev npaj ntawm CsxWO3 Coated iav

Tom qab cov hmoov CsxWO3 yog tag nrho hauv av thiab ultrasonically dispersed, nws yog ntxiv rau 0.1g / ml polyvinyl cawv PVA tov, nplawm hauv dej ntawm 80 ° C rau 40 feeb, thiab tom qab laus rau 2 hnub, yob txheej ntawm cov iav zoo tib yam (7cm. * 12cm) * 0.3cm) Nws yog coated los ua ib zaj duab xis nyias kom tau CsxWO3 coated iav.

Thermal rwb thaiv tsev kev ua tau zoo ntawm CsxWO3 coated iav

Lub thawv rwb thaiv tsev yog ua los ntawm foam board.Qhov chaw sab hauv ntawm lub thawv rwb thaiv tsev yog 10cm * 5cm * 10.5cm.Sab saum toj ntawm lub thawv muaj lub qhov rais duab plaub ntawm 10cm * 5cm.Hauv qab ntawm lub thawv yog them nrog lub phaj hlau dub, thiab tus pas ntsuas kub yog nruj nreem txuas nrog cov hlau dub.Qhov saum npoo ntawm lub rooj tsavxwm.Muab cov iav coated nrog CsxWO3 rau ntawm lub qhov rais ntawm qhov chaw tshav kub-insulating, kom cov coated ib feem npog tag nrho lub qhov rais ntawm qhov chaw, thiab irradiate nws nrog ib tug 250W infrared teeb ntawm ib tug ntsug nrug ntawm 25cm ntawm lub qhov rais.Qhov kub nyob rau hauv lub thawv kaw nws txawv nrog Kev sib raug zoo ntawm lub sij hawm raug hloov.Siv tib txoj kev los ntsuas cov iav dawb paug.Raws li kev sib kis spectrum ntawm CsxWO3 coated iav, CsxWO3 coated iav nrog cov ntsiab lus sib txawv cesium muaj qhov sib kis tau zoo ntawm cov teeb pom kev zoo thiab qhov tsis tshua muaj hluav taws xob ze-infrared (800-1100nm).NIR shielding sib txawv nce nrog nce ntawm cov ntsiab lus cesium.Ntawm lawv, Cs0.33WO3 coated iav muaj qhov zoo tshaj plaws NIR shielding sib.Qhov siab tshaj plaws transmittance nyob rau hauv lub pom teeb pom kev zoo yog piv nrog lub transmittance ntawm 1100nm nyob rau hauv lub ze infrared cheeb tsam.Kev xa tawm ntawm cheeb tsam tau poob li ntawm 12%.

Thermal rwb thaiv tsev nyhuv ntawm CsxWO3 coated iav

Raws li cov txiaj ntsig kev sim, muaj qhov sib txawv ntawm cov cua sov ua ntej CsxWO3 coated iav nrog cov ntsiab lus sib txawv ntawm cov cesium thiab cov iav tsis muaj xim dawb.Cov cua kub zoo nkauj ntawm CsxWO3 txheej zaj duab xis nrog cov ntsiab lus sib txawv ntawm cov cesium yog qis dua li ntawm cov iav dawb.CsxWO3 cov yeeb yaj kiab nrog cov ntsiab lus sib txawv ntawm cov ntsiab lus muaj cov thermal rwb thaiv tsev zoo, thiab cov thermal rwb thaiv tsev ntawm CsxWO3 zaj duab xis nce nrog nce cov ntsiab lus ntawm cov ntsiab lus.Ntawm lawv, Cs0.33WO3 zaj duab xis muaj qhov zoo tshaj plaws thermal rwb thaiv tsev nyhuv, thiab nws cov thermal rwb thaiv tsev kub sib txawv tuaj yeem ncav cuag 13.5 ℃.Lub thermal rwb thaiv tsev nyhuv ntawm CsxWO3 zaj duab xis los ntawm ze-infrared (800-2500nm) shielding kev ua tau zoo ntawm CsxWO3.Feem ntau, qhov zoo dua qhov ze-infrared shielding kev ua tau zoo, qhov zoo dua nws cov thermal rwb thaiv tsev kev ua tau zoo.
