Galasi laminated imatchedwanso galasi lachitetezo, limapangidwa ndi zidutswa ziwiri kapena zingapo zamagalasi ndi filimu ya interlayer pansi pa kutentha kwakukulu komanso kuthamanga kwambiri.Galasi laminated imawonetsedwa ndi makhalidwe otsatirawa.
Choyamba, chitetezo chabwino.Gawo la interlayer lili ndi kulimba kwabwino, kugwirizana kwapamwamba komanso kukana kulowa mkati.Zidutswa pambuyo pa magalasi osweka zidzamamatirana molimba popanda kumwazikana, zinthu zina sizikanatha kulowamo mosavuta, ndiye galasi laminated lingapereke chitetezo kwa anthu ndi katundu.Magalasi opangidwa ndi laminated omwe amagwiritsidwa ntchito pakhoma lapamwamba la chinsalu sangagwe kuti awononge, panthawiyi akhoza kulepheretsa anthu ndi anthu kuti asalowe mu galasi ndikugwa.Ndiye izo ndi za galasi lachitetezo ndithudi.
Chachiwiri, magwiridwe antchito apamwamba a ultraviolet.The interlayer mu galasi laminated, makamaka PVB wosanjikiza ali apamwamba ultraviolet mayamwidwe ntchito, akhoza kusefera ultraviolet amene amadutsa mu galasi laminated, kusefera ake ntchito akhoza kukwera mpaka 99%.
Chachitatu, Kuchita bwino kosamveketsa mawu.Cholumikizira mu galasi lopangidwa ndi laminated chimatha kuyamwa mafunde a phokoso, makamaka wosanjikiza wa PVB amakhala ndi umboni womveka bwino, ndipo PVB yotsimikizira mawu pamsika imakhala ndi magwiridwe antchito abwino kwambiri.
Pali mitundu ya inter-zigawo kwa galasi laminated, PVB, EVA ndi SGP.Filimu ya PVB imagwiritsidwa ntchito kwambiri ndi mbiri yakale kwambiri.Tchati chotsatiridwa chikuwonetsa kusiyana kwa mawonekedwe amitundu itatu ya interlayer.
PVB ndi chidule cha Polyvinyl Butyral, imakhala ndi mgwirizano wabwino wagalasi, koma sinathe kumamatira kuchitsulo bwino, kukana madzi ndikoyipa.Kutentha kukakhala kopitilira 70 ℃, mgwirizanowo udazimiririka mwachangu.PVB ikagwiritsidwa ntchito panja ndi poyera, imabwera mosavutikira.Mtundu wa PVB ndi wosiyana, womveka, woyera, pinki, wabuluu, wobiriwira, wachikasu, wofiira, ndi mitundu ina ikhoza kupangidwa malinga ndi zofunikira zosiyanasiyana.The makulidwe yachibadwa kwa PVB ndi 0.38mm, 0.76mm, 1.14mm, 1.52mm.Itha kugwiritsidwa ntchito mopitilira muyeso molingana ndi mitundu yosiyanasiyana komanso zofunikira za makulidwe.
Ndi zofunika pa zotsatira zomveka zomveka, PVB-umboni wa mawu ikukhala yotchuka kwambiri.PVB yokhala ndi phokoso imakhala ndi ntchito yabwino yochepetsera kusiyana ndi PVB yachibadwa, imatha kuletsa kufalikira kwa phokoso, makamaka kwa nyumba yomwe ili pafupi ndi eyapoti, siteshoni, malo ogulitsa ndi m'mphepete mwa msewu, zotsatira zomveka bwino zimakhala zabwino.
EVA ndi chidule cha ethylene-vinyl acetate copolymer, imakhala ndi mgwirizano wabwino wa galasi ndi zitsulo, kukana kwa madzi ndikwabwino, koma mphamvu ya misozi si yabwino monga PVB ndi SGP.Kutentha kwa kutentha kuli bwino kuposa PVB, koma osati bwino monga SGP, ndiye kumagwiritsidwa ntchito makamaka m'munda wa photovoltaics.Pakakhala mbale zachitsulo mu gawo la interlayer, kapena galasi lidzagwiritsidwa ntchito kunja ndi interlayer yowonekera, EVA ndiye chisankho chabwinoko.Koma pakhoma lotchinga, cholumikizira cha EVA sichikuperekedwa.
SGP ikhoza kuonedwa ngati yosinthidwa ya polymethyl methacrylate, imakhala ndi mgwirizano wabwino ku galasi ndi zitsulo, kukana kwa madzi kulinso kwabwino, kungagwiritsidwe ntchito kutentha kwambiri (＜82 ℃).Ngakhale galasi wosweka, otsala mphamvu ndi mkulu, kukhala ndi chitetezo chapamwamba.SGP ndiye nambala ya Ionic membrane yochokera ku kampani ya DuPont ndi America, imatchedwanso SuperSafeGlas.Mphamvu yotsalira ndi kukana madzi kwa galasi la SGP laminated, limapangitsa kuti likhale loyenera lomwe limagwiritsidwa ntchito ngati galasi pansi.
