EVA (Ethylene Vinyl Acetate) thiab PVB (Polyvinyl Butyral) yog ob hom interlayers siv hauv cov iav laminated. Qhov sib txawv tseem ceeb ntawm EVA thiab PVB laminated iav yog nyob rau hauv lawv cov khoom thiab kev siv. Nov yog qee qhov kev sib txawv tseem ceeb:
Kev sib xyaw:EVA yog cov khoom siv thermoplastic ua los ntawm cov copolymer ntawm ethylene thiab yas acetate, thaum PVB yog cov thermoplastic resin ua los ntawm polyvinyl butyral.
Clarity:EVA muaj qhov pom tseeb dua piv rau PVB. Nws muab qhov pom tseeb dua los ntawm cov iav, ua rau nws tsim nyog rau cov ntawv thov uas pom qhov pom tseeb yog qhov tseem ceeb, xws li cov khw muag khoom, tsev cia puav pheej, lossis cov duab kos duab.
UV Resistance:EVA muaj kev tiv thaiv zoo dua rau ultraviolet (UV) rays piv rau PVB. Nws muaj kev tiv thaiv zoo tiv thaiv UV hluav taws xob, tiv thaiv fading lossis kev puas tsuaj rau cov khoom tom qab iav, xws li kos duab lossis rooj tog.
Suab rwb thaiv tsev:PVB muaj lub suab rwb thaiv tsev zoo dua piv rau EVA. Nws txo cov suab nrov zoo, ua rau nws zoo tagnrho rau cov ntawv thov uas txo cov suab nrov yog qhov tseem ceeb, xws li hauv cov tsev nyob ze ntawm txoj kev tsis khoom lossis tshav dav hlau.
Kev Nyab Xeeb thiab Kev Nyab Xeeb:Ob leeg EVA thiab PVB laminated iav muab kev nyab xeeb thiab kev nyab xeeb los ntawm kev tuav lub khob ua ke thaum tawg. Txawm li cas los xij, PVB ib txwm siv rau hauv cov ntawv thov uas xav tau cov qauv kev nyab xeeb siab dua, xws li lub tshuab cua tshuab, vim nws qhov kev cuam tshuam zoo heev thiab muaj peev xwm tiv thaiv iav los ntawm kev tawg mus rau hauv cov khoom ntse.
Kev tsim khoom:EVA laminated iav feem ntau yog tsim los siv cov txheej txheem cua sov thiab lub tshuab nqus tsev, thaum PVB laminated iav yog tsim los ntawm cov txheej txheem kub thiab siab. Cov txheej txheem tsim khoom sib txawv tuaj yeem cuam tshuam tag nrho qhov zoo thiab kev ua haujlwm ntawm cov iav laminated.
Thaum kawg, kev xaiv ntawm EVA thiab PVB laminated iav yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov. EVA feem ntau nyiam rau cov ntawv thov uas saib xyuas qhov pom tseeb thiab UV tsis kam, thaum PVB feem ntau siv rau hauv cov ntawv thov kev nyab xeeb, kev ruaj ntseg, thiab lub suab rwb thaiv tsev yog qhov tseem ceeb.
