Coated iav yog txheej txheem ntawm txheej ib los yog ntau txheej ntawm hlau, alloy, los yog hlau compound nyias zaj duab xis nyob rau saum npoo ntawm iav los hloov nws cov khoom kho qhov muag thiab ua tau raws li cov kev cai tshwj xeeb.
Coated iav tuaj yeem muab faib ua cov pawg hauv qab no raws li cov yam ntxwv sib txawv ntawm cov khoom: cov khoom siv hluav taws xob ua kom sov, cov iav qis E, cov iav zaj duab xis, thiab lwm yam. Thaum tshav kub kub reflective iav feem ntau coated nrog ib lossis ntau txheej ntawm nyias zaj duab xis tsim los ntawm cov hlau. los yog lawv cov tebchaw xws li chromium, titanium, los yog stainless hlau nyob rau saum npoo ntawm lub iav, ua rau cov khoom nplua nuj xim, nrog rau qhov tsim nyog transmittance rau pom lub teeb, siab reflectivity rau lub teeb infrared, thiab high absorption tus nqi rau ultraviolet lub teeb. Yog li ntawd, nws tseem hu ua lub hnub ci tswj iav thiab feem ntau yog siv hauv cov tsev thiab iav ntaub thaiv phab ntsa; Cov iav hluav taws xob tsawg yog cov txheej txheem ua yeeb yaj kiab nyias uas muaj ntau txheej hlau xws li nyiaj, tooj liab, tin, lossis lawv cov khoom sib xyaw ua ke ntawm cov iav. Cov khoom muaj siab transmittance rau pom lub teeb thiab siab reflectivity rau infrared tawg, thiab muaj zoo thermal rwb thaiv tsev kev ua tau zoo. Nws yog tsuas yog siv hauv kev tsim kho, tsheb, nkoj, thiab lwm yam cuab yeej sib txuas lus. Vim yog lub zog tsis zoo ntawm cov yeeb yaj kiab txheej, nws feem ntau ua rau cov iav insulating siv; Conductive zaj duab xis iav yog ib tug conductive nyias zaj duab xis coated rau saum npoo ntawm iav, xws li indium tin oxide, uas yuav siv tau rau cua sov, defrosting, defogging iav, thiab raws li ib tug kua siv lead ua zaub screen;
Muaj ntau ntau txoj hauv kev ntawm cov iav coated, feem ntau suav nrog lub tshuab nqus tsev magnetron sputtering, nqus evaporation, tshuaj vapor deposition thiab sol gel txoj kev. Magnetron sputtering coated iav tuaj yeem tsim thiab tsim nrog ntau txheej txheej zaj duab xis siv tshuab magnetron sputtering. Ntau cov xim tuaj yeem plated ntawm cov iav dawb substrates, thiab cov yeeb yaj kiab txheej tau zoo corrosion kuj thiab hnav tsis kam. Tam sim no nws yog ib qho ntawm cov khoom tsim thiab siv ntau tshaj plaws. Muaj qhov sib txawv ntawm ntau yam thiab qhov zoo ntawm lub tshuab nqus tsev vacuum coated iav piv rau magnetron sputtering coated iav, thiab nws tau maj mam hloov los ntawm lub tshuab nqus tsev sputtering. Tshuaj vapor deposition (CVD) yog ib tug txheej txheem nyob rau hauv uas ib tug reactive gas yog nkag mus rau hauv ib tug ntab iav ntau lawm kab kom decompose lub kub nto ntawm iav thiab tso nws uniformly ntawm lub iav nto los ua ib tug coated iav. Cov yam ntxwv ntawm txoj kev no yog cov cuab yeej siv qis, kev tswj xyuas yooj yim, cov khoom siv qis, kev ruaj ntseg tshuaj zoo, thiab muaj peev xwm ua tau zoo thermal ua. Tam sim no nws yog ib txoj hauv kev zoo tshaj plaws ntau lawm. Cov txheej txheem sol gel rau tsim cov iav coated yog qhov yooj yim thiab ruaj khov, tab sis qhov tsis zoo yog tias lub teeb xa tawm ntawm cov khoom yog siab dhau thiab kho kom zoo nkauj tsis zoo.
Feem ntau siv cov iav coated yog cov iav uas muaj cua sov thiab cov iav tsis muaj emissivity. Yeej, ob txoj kev tsim khoom yog siv: lub tshuab nqus tsev magnetron sputtering thiab tshuaj vapor deposition. Cov tuam txhab nto moo thoob ntiaj teb ntawm cov khoom siv nqus hlau nplaum muaj xws li BOC los ntawm Tebchaws Meskas thiab Leybold los ntawm Lub Tebchaws Yelemees, thaum cov tuam txhab nto moo ntawm cov tshuaj vapor deposition suav nrog Pilkington los ntawm United Kingdom. Txij li thaum xyoo 1980s lig, ntau pua lub tuam txhab iav coated tau tshwm sim hauv Suav teb. Nqus magnetron sputtering txoj kev tuam txhab uas muaj kev cuam tshuam loj hauv kev lag luam suav nrog Tuam Tshoj Southern Glass Group Corporation thiab Shanghai Sunshine Coated Glass Company. Chemical vapor deposition method manufacturers suav nrog Shandong Blue Star Glass Company thiab Yangtze River Float Glass Company.
