Laminated iav yog hom iav kev ruaj ntseg uas tuav thaum sib tawg. Thaum muaj kev tawg, nws muaj nyob rau ntawm qhov chaw sib txuas, xws li polyvinyl butyral (PVB) lossis ethylene-vinyl acetate (EVA), nruab nrab ntawm nws ob los yog ntau khaubncaws sab nraud povtseg ntawm iav. Lub interlayer ua rau cov khaubncaws sab nraud povtseg ntawm iav bonded txawm tias thaum tawg, thiab nws lub zog siab tiv thaiv cov iav ntawm rhuav tshem mus ua cov ntse ntse. Qhov no ua rau tus cwj pwm "kab laug sab lub vas sab" ntuag thaum qhov kev cuam tshuam tsis txaus rau tag nrho lub khob. Nyob rau hauv rooj plaub ntawm EVA, lub thermoset EVA, muaj ib qho kev sib tw (sib txuas) nrog cov ntaub ntawv seb nws yog iav, polycarbonate, PET, lossis lwm hom khoom.
Laminated iav yog ib txwm siv thaum muaj ib qho kev tshwm sim los ntawm tib neeg los yog qhov iav yuav poob yog tias tau tawg thiab tseem siv architectural applications. Skylight glazing thiab sutomobile cua shields feem ntau siv laminated iav. Hauv thaj chaw uas yuav tsum tau siv lub pas nrig cua daj cua dub uas tsis muaj teeb meem, lub laminated iav siv feem ntau ntawm cov khoom siv sab nraud, cov phab ntsa ntaub thaiv thiab qhov rais.
Laminated iav yog siv los ua kom lub suab rwb thaiv tsev ntawm qhov rais, qhov tseem ceeb-ua rau lub suab nrov zoo dua qub los ntawm monolithic iav panes ntawm tib lub thickness.Thaum lub hom phiaj no tshwj xeeb "acoustic PVB" compound yog siv rau interlayer. Nyob rau hauv cov ntaub ntawv ntawm EVA th -is khoom, tsis muaj ntaub ntawv ntxiv acoustic yog yuav tsum tau, vim hais tias EVA muab lub suab rwb thaiv tsev.Tau ntxiv cov cuab yeej ntawm laminated iav rau lub qhov rais yog tias ib PVB thiab EVA interlayer yuav thaiv tau feem ntau ultraviolet hluav taws xob. Lub thermoset EVA yuav thaiv tau 99.9% ntawm UV rays.
