Glass ya Low-E, Glass Low Emissivity, Low Emissivity Coated Glass

Chapakati pa zaka za m'ma 1970, zidadziwika kuti kutentha kwa mawindo owoneka kawiri kumabwera chifukwa cha kusinthana kwa ma radiation ofiira kuchokera pagalasi imodzi kupita ku ina.Choncho, kusamutsidwa kwa kutentha kowala kumatha kuchepetsedwa kwambiri mwa kuchepetsa mpweya wamtundu uliwonse wa glazing iwiri.Ndipamene galasi la Low-E limalowa.
Glass ya Low-e, yaifupi yotanthauza Low-emissivity Glass."Low-E Glass" amatanthauza zinthu zingapo zogwira ntchito kwambiri, zosatulutsa mpweya pang'ono zopangidwa ndi zida zapamwamba kwambiri zokutira zovumbula. ndi zigawo zingapo za zipangizo zosiyanasiyana.Mwa izi, siliva wosanjikiza umawonetsa bwino kuwala kwa infrared ndikusunga magwiridwe antchito abwino kwambiri.Pansi pa siliva wosanjikiza pali anti-reflective tin oxide (SnO2) base layer yomwe imawonjezera kuwonekera kwa galasi.Pamwamba pa siliva wosanjikiza pali zokutira za nickel-chromium (NiCr) alloy.Ntchito yaikulu ya pamwamba anti-reflective tin oxide (SnO2) wosanjikiza ndi kuteteza zigawo zina zokutira.Magalasi amtunduwu samangokhala ndi ma transmittance owoneka bwino, komanso amakhala ndi chotchinga cholimba cha infuraredi, chomwe chimatha kusewera pawiri pakuwunikira kwachilengedwe komanso kutchinjiriza kutentha komanso kupulumutsa mphamvu.Pambuyo pa ntchito, imatha kuchepetsa kutayika kwakunja kwa kutentha kwamkati m'nyengo yozizira, komanso imatha kuletsa ma radiation yachiwiri ya zinthu zakunja zomwe zimatenthedwa ndi dzuwa m'chilimwe, kuti zisewere cholinga chopulumutsa mphamvu ndikuchepetsa kugwiritsa ntchito.Panthawi imodzimodziyo, galasi la Low-E limakhala ndi transmittance yapamwamba mu gulu lowoneka, lomwe lingathe kugwiritsa ntchito kwambiri kuwala kwachilengedwe m'nyumba. ma radiation panja, ndikukwaniritsa njira yabwino yopulumutsira mphamvu.Panthawi imodzimodziyo, mafuta omwe amatenthedwa ndi kutentha amatha kuchepetsedwa kwambiri, motero kuchepetsa kutuluka kwa mpweya woipa.
Chogulitsachi chimapereka kuwonekera kwakukulu, kuwonetsetsa pang'ono, kutsekemera kwapamwamba kwa kutentha ndi mphamvu zopulumutsa mphamvu zomwe zimafunikira magalasi amakono omangamanga ndi zomangamanga zobiriwira.
