Iglasi ye-Low-E, ekwabizwa ngokuba yiglasi ye-low-emissivity, yimveliso esekwe kwifilim eyenziwe ngamaleko amaninzi esinyithi okanye ezinye iikhompawundi ezifakwe kumphezulu weglasi.Umaleko wokugquma uneempawu zokuhanjiswa okuphezulu kokukhanya okubonakalayo kunye nokubonakaliswa okuphezulu kwemitha ye-infrared ephakathi kunye nekude, eyenza ibe nefuthe elihle kakhulu lokugquma ubushushu kunye nokuhanjiswa kokukhanya okuhle xa kuthelekiswa neglasi eqhelekileyo kunye neglasi egqunyiweyo yemveli.
Iglasi yinto ebalulekileyo yokwakha.Ngokuphuculwa okuqhubekayo kweemfuno zokuhlobisa izakhiwo, ukusetyenziswa kweglasi kwishishini lokwakha kuyanda.Namhlanje, nangona kunjalo, xa abantu bekhetha iifestile zeglasi kunye neengcango zezakhiwo, ngaphezu kweempawu zabo zobuhle kunye nenkangeleko, bahlawula ingqalelo engakumbi kwimiba efana nokulawula ubushushu, iindleko zokupholisa kunye nokulungelelaniswa kokukhanya kwelanga kwangaphakathi.Oku kwenza iglasi ye-Low-E ephezulu kwintsapho yeglasi egqunyiweyo igqame kwaye ibe yingqwalasela.

Iimpawu ezibalaseleyo ze-thermal
Ukulahleka kobushushu bomnyango wangaphandle kunye neglasi yefestile iyona nxalenye ephambili yokwakha ukusetyenziswa kwamandla, kubalwa ngaphezu kwe-50% yokusetyenziswa kwamandla okwakhiwa.Idatha yophando efanelekileyo ibonisa ukuba ukuhanjiswa kobushushu kumhlaba ongaphakathi weglasi ubukhulu becala yimitha, ibalwa kwi-58%, oku kuthetha ukuba eyona ndlela isebenzayo yokunciphisa ilahleko yamandla obushushu kukutshintsha ukusebenza kweglasi.Ukukhutshwa kweglasi yeglasi eqhelekileyo kuphezulu njenge-0.84.Xa umaleko wefilimu esekelwe kwisilivere ephantsi-emissivity igqunywe, ukukhupha kungancitshiswa kube ngaphantsi kwe-0.15.Ke ngoko, ukusetyenziswa kweglasi ephantsi kwe-E ukwenza iingcango zesakhiwo kunye neefestile kunokunciphisa kakhulu ukuhanjiswa kwamandla obushushu angaphakathi okubangelwa yimitha yemitha ngaphandle, kunye nokufezekisa iziphumo ezifanelekileyo zokonga amandla.
Olunye uncedo olubalulekileyo lokunciphisa ukulahleka kobushushu ngaphakathi kukhuseleko lokusingqongileyo.Ngexesha elibandayo, ukukhutshwa kweegesi ezinobungozi ezifana ne-CO2 kunye ne-SO2 ebangelwa ukufudumeza kwesakhiwo ngumthombo obalulekileyo wokungcola.Ukuba iglasi ye-Low-E isetyenzisiweyo, ukusetyenziswa kwamafutha okufudumeza kungancitshiswa kakhulu ngenxa yokunciphisa ukulahleka kobushushu, ngaloo ndlela kuncitshiswe ukukhutshwa kweegesi eziyingozi.
Ubushushu obudlula kwiglasi bu-bidirectional, oko kukuthi, ubushushu bunokudluliselwa ukusuka kwindlu yangaphakathi ukuya ngaphandle, kwaye ngokuphambene noko, kwaye kuqhutyelwa ngexesha elifanayo, kuphela ingxaki yokudluliselwa kobushushu obuhlwempuzekileyo.Ebusika, iqondo lokushisa langaphakathi liphezulu kunelo langaphandle, ngoko ke i-insulation iyafuneka.Ehlotyeni, iqondo lokushisa langaphakathi liphantsi kuneqondo lokushisa langaphandle, kwaye iglasi iyadingeka ukuba ifakwe i-insulated, oko kukuthi, ukushisa kwangaphandle kudluliselwa kwindlu yangaphakathi ngokuncinci kunokwenzeka.Iglasi ye-E ephantsi inokuhlangabezana neemfuno zasebusika kunye nehlobo, zombini ukugcinwa kobushushu kunye nokufudumala ukushisa, kwaye kunempembelelo yokukhusela indalo kunye nekhabhoni ephantsi.

Iimpawu ezintle ze-optical
Ukuhanjiswa kokukhanya okubonakalayo kweglasi ye-Low-E isuka kwi-0% ukuya kwi-95% kwithiyori (i-6mm yeglasi emhlophe kunzima ukuyifumana), kunye nokuhanjiswa kokukhanya okubonakalayo kubonisa ukukhanya kwangaphakathi.Ukubonakaliswa kwangaphandle kumalunga ne-10% -30%.Ukubonakaliswa kwangaphandle kukukhanya okubonakalayo okubonakalayo, okumele ukuqina okubonakalayo okanye idigri eqaqambileyo.Okwangoku, i-China idinga ukukhanya okubonakalayo kodonga lwamakhethini ukuba kungabi ngaphezu kwe-30%.
Ezi mpawu zingasentla zeglasi ye-Low-E yenze ukuba isetyenziswe ngokubanzi kumazwe aphuhlileyo.ilizwe lam lilizwe elingenawo amandla.Ukusetyenziswa kwamandla ngomntu ngamnye kuphantsi kakhulu, kwaye usetyenziso lwamandla okwakha lubalelwa kuma-27.5% osetyenziso lwamandla lulonke lwelizwe.Ngoko ke, ukuphuhlisa ngamandla iteknoloji yokuvelisa i-Low-E yeglasi kunye nokukhuthaza intsimi yesicelo sayo ngokuqinisekileyo kuya kuzisa inzuzo ebalulekileyo yentlalo kunye nezoqoqosho.Kwimveliso yeglasi ye-Low-E, ngenxa yobungcali bezinto eziphathekayo, ineemfuno eziphezulu zokucoca iibhulashi xa zidlula kumatshini wokucoca.Ucingo lwebrashi kufuneka lube ludidi oluphezulu lwebrashi yenayiloni efana ne-PA1010, PA612, njl.Ngenxa yokuba ucingo lwebrashi lunokuthamba okulungileyo, ukuqina okuqinileyo, ukuxhathisa kwe-asidi kunye ne-alkali, kunye nokumelana nobushushu, kunokususa lula uthuli kwiglasi ngaphandle kokubangela imikrwelo phezu komhlaba.

Iglasi egqunywe nge-Low-E egqunywe nge-insulating yeyona nto ingcono yokonga umbane.Inokudluliselwa kwelanga eliphezulu, ixabiso eliphantsi kakhulu "u", kwaye, ngenxa yesiphumo sokugquma, ubushushu obubonakaliswe yiglasi ye-Low-E bubuyiselwa kwigumbi, okwenza ubushushu kufuphi neglasi yefestile buphakame, kwaye abantu ayikhuselekanga kufutshane neglasi yefestile.uzakuziva ungakhululekanga kakhulu.Isakhiwo esineglasi yefestile ye-Low-E sinobushushu obuphezulu bangaphakathi, ngoko sinokugcina ubushushu obuphezulu bendlu ebusika ngaphandle kweqabaka, ukuze abantu abangaphakathi bazive bekhululekile.Iglasi ye-E ephantsi inokuthintela ukuhanjiswa kwe-UV encinci, eluncedo kancinci ekuthinteleni ukubuna kwezinto zangaphakathi.
