Laminated iav tseem hu ua iav kev nyab xeeb, nws yog ua los ntawm ob lossis ntau daim iav nrog interlayer zaj duab xis nyob rau hauv qhov kub thiab txias.Laminated iav yog tshwj xeeb los ntawm cov yam ntxwv hauv qab no.
Ua ntej, Kev ruaj ntseg zoo.Lub interlayer ib feem muaj zoo toughness, superior cohesiveness thiab siab nkag tsis kam.Cov fragments tom qab iav tawg yuav lo ua ke nruj nreem tsis tawg, lwm yam khoom tsis tuaj yeem nkag mus tau yooj yim, ces cov iav laminated tuaj yeem muab kev nyab xeeb rau tib neeg thiab cov khoom.Cov iav laminated uas tau siv rau hauv cov ntaub thaiv phab ntsa siab yuav tsis poob los ua kev puas tsuaj, lub sijhawm no tuaj yeem tiv thaiv cov neeg thiab cov neeg los ntawm kev nkag mus rau iav thiab lub caij nplooj zeeg.Tom qab ntawd nws belongs rau lub iav kev nyab xeeb tiag tiag.
Thib ob, kev ua haujlwm siab ultraviolet-pov thawj.Lub interlayer nyob rau hauv lub laminated iav, tshwj xeeb tshaj yog cov PVB txheej muaj superior ultraviolet absorption muaj nuj nqi, yuav filtrate lub ultraviolet uas dhau los ntawm lub laminated iav, nws pom muaj nuj nqi yuav nce mus txog 99%.
Thib peb, Zoo suab-pov thawj kev ua tau zoo.Lub interlayer nyob rau hauv lub laminated iav yuav nqus tau lub suab yoj, tshwj xeeb tshaj yog cov PVB txheej muaj superior suab-pov thawj, thiab lub suab-pov thawj PVB nyob rau hauv lub lag luam muaj zoo suab-pov thawj.
Muaj ntau hom txheej txheej rau cov iav laminated, PVB, EVA thiab SGP.PVB zaj duab xis feem ntau yog siv nrog cov keeb kwm ntev tshaj plaws.Ua raws li daim ntawv qhia qhia qhov sib txawv rau tus yam ntxwv hauv peb hom interlayer.
PVB yog cov ntawv luv ntawm Polyvinyl Butyral, nws muaj kev sib raug zoo rau iav, tab sis tsis tuaj yeem lo rau hlau zoo, cov dej tsis zoo.Thaum qhov kub siab tshaj 70 ℃, lub cohesiveness faded sai.Thaum PVB siv sab nraud thiab raug, nws yooj yim tuaj unglued.Cov xim ntawm PVB yog txawv, meej, dawb, liab, xiav, ntsuab, daj, liab, thiab lwm yam xim muaj peev xwm ua tau raws li kev cai sib txawv.Qhov tuab tuab rau PVB yog 0.38mm, 0.76mm, 1.14mm, 1.52mm.Nws tuaj yeem siv overlying raws li cov xim sib txawv thiab thickness.
Nrog rau qhov yuav tsum tau ua rau lub suab pov thawj, suab pov thawj PVB tau dhau los ua neeg nyiam.Lub suab pov thawj PVB muaj kev ua haujlwm zoo dua li PVB ib txwm, nws tuaj yeem txwv tsis pub lub suab nrov nrov, tshwj xeeb tshaj yog rau lub tsev uas nyob ze tshav dav hlau, chaw nres tsheb, khw muag khoom thiab ib sab ntawm txoj kev, lub suab pov thawj zoo meej.
EVA yog cov ntawv luv ntawm ethylene-vinyl acetate copolymer, nws muaj kev sib koom ua ke zoo rau iav thiab hlau, cov dej tsis zoo, tab sis lub zog tsim kua muag tsis zoo li PVB thiab SGP.Qhov kub tsis kam yog zoo dua PVB, tab sis tsis zoo li SGP, ces tsuas yog siv nyob rau hauv lub photovoltaics teb.Thaum muaj hlau phaj nyob rau hauv interlayer ib feem, los yog cov iav yuav siv sab nraum nrog interlayer raug, EVA yog qhov kev xaiv zoo dua.Tab sis rau cov ntaub thaiv phab ntsa, EVA interlayer tsis pom zoo.
SGP tuaj yeem suav tau tias yog hloov pauv polymethyl methacrylate, nws muaj kev sib raug zoo rau iav thiab hlau, cov dej kuj tseem zoo, tuaj yeem siv rau hauv qhov kub siab (＜82 ℃).Txawm tias cov iav tawg, qhov seem ntawm lub zog kuj yog siab, muaj kev ruaj ntseg zoo dua.SGP yog cov cai rau Ionic membrane los ntawm DuPont tuam txhab yog America, nws tseem hu ua SuperSafeGlas.Qhov ntxiv dag zog thiab dej tsis kam rau SGP laminated iav, ua rau nws haum uas siv los ua iav hauv pem teb.
