Kev sib piv ntawm "lub zog" ntawm laminated iav thiab tempered iav yuav tsum tau sib tham los ntawm ntau qhov ntev - lawv cov cheeb tsam ntawm qhov zoo sib txawv, thiab nws tsis tuaj yeem hais ncaj qha rau qhov twg yog qhov muaj zog dua.
Tempered iav: Nyuaj thiab siab dua- tiv taus, tab sis nws tawg tag thaum tawg.
Laminated iav: Los tiv thaiv -ntev tempered iav uas tuaj yeem tiv taus txawm tias tawg.
Cov lus piav qhia ntxaws txog kev sib piv sib piv
Impact zog (ib qho kev cuam tshuam)
Tempered iav
Lub zog saum npoo yog 4 mus rau 5 npaug ntawm cov iav zoo tib yam (kwv yees li 150MPa lossis ntau dua), thiab nws tuaj yeem tiv taus qhov cuam tshuam ntau dua (xws li cua daj cua dub, cua daj cua dub).
Kev tuag tsis muaj zog: Thaum lub ntsiab lus tseem ceeb hla dhau, tag nrho cov iav tam sim ntawd tawg mus rau hauv cov khoom, ua rau poob tag nrho nws qhov kev cuam tshuam.
Laminated iav
Ib txheej - lub zog yog ze rau ntawm cov iav zoo tib yam, tab sis cov yeeb yaj kiab interlayer (PVB/SGP) tuaj yeem nqus tau lub zog.
Txawm hais tias cov iav txheej tawg, cov yeeb yaj kiab interlayer tseem tuaj yeem tiv thaiv cov khoom los ntawm kev nkag mus (xws li cov khoom ya hauv kev sim nag xob nag cua).
Scene pov thawj
Impact test nrog 9mm steel pob (ASTM F1233):
6 hli tempered iav: tuaj yeem tiv taus lub zog ntawm kwv yees li 5.5 joules (nrog cov khoom ya tom qab tawg);
6mm+1.52mm PVB+6mm laminated iav: tuaj yeem tiv taus> 30 joules (iav tawg tab sis tsis nkag mus).
Kev sib piv ntawm hom kev txhim kho tshwj xeeb
Yog tias tempered iav siv los ua lub substrate rau laminated iav (tempered laminated iav):
Kev cuam tshuam lub zog=hardness ntawm tempered iav + toughness ntawm interlayer zaj duab xis → muaj zog tshaj plaws;
Anti-kev nkag mus crushed ntshiab tempered iav (xws li iav mos txwv, uas yog multi- txheej tempered laminated +PC).
Key Scene Xaiv Phau Ntawv Qhia
Cov xwm txheej uas tempered iav yog qhov kev xaiv zoo dua
Cov cheeb tsam cua siab siab (xws li super siab-nce kab hlau rhuav phab ntsa)
Tempered iav muaj zog dua dabtsi yog khoov thiab deformation tsawg dua (nws yuav tsum ua raws li "Technical Code for Application of Building Glass" JGJ 113).
Tsawg-cov nqi kev nyab xeeb (xws li cov chaw sab hauv tsev, chav da dej):
Nws ua tau raws li qhov yooj yim los tiv thaiv- kev ua kom tawg thiab nws tus nqi tsuas yog 1/3 rau 1/2 ntawm cov iav laminated.
Tsis kam mus rau qhov kub thiab txias tam sim ntawd hloov (xws li lub qhov rooj qhov cub):
Nws cov thermal stability zoo dua li cov iav laminated (laminated zaj duab xis yog nquag bubbling ntawm qhov kub thiab txias).
Cov xwm txheej uas cov iav laminated yog qhov kev xaiv zoo dua
Hurricane/Typhoon tiv thaiv cheeb tsam:
Nws yuav tsum dhau qhov kev ntsuam xyuas qhov projectile (tempered iav ib leeg tsis tuaj yeem ua tau raws li tus qauv).
Kev tiv thaiv -smash/anti- kev cai tub sab nyiag / mos txwv:
Cov tuam txhab nyiaj hauv tuam txhab, cov khw muag khoom siv nyiaj txiag (qhov tuab ntawm cov yeeb yaj kiab nruab nrab, qhov muaj zog tiv thaiv).
Siab - thaj tsam nyab xeeb
Skylights thiab lub teeb ru tsev (tsis txhob poob thaum tawg los tiv thaiv cov khoom ntog los ntawm qhov siab).
Qhov chaw nrog menyuam yaus/cov neeg laus:
Qhov rooj, qhov rais thiab guardrails (kom tiv thaiv cov khib nyiab los ntawm kev txaws thiab tawg tom qab kev cuam tshuam).
Cov txheej txheem kev ua tau zoo
Qhov kawg lub zog ua ke: tempered laminated iav + SGP zaj duab xis
Piv txwv li: 8mm tempered iav + 1.52mm SGP zaj duab xis + 8mm tempered iav
Kev ua tau zoo
Lub zog flexural yog kwv yees li 90% ntawm ib qho tempered iav (tsuas yog txo me ntsis).
Kev nkag mus tau zoo dua los ntawm 300% (piv nrog ib lub iav tempered);
Tau dhau qhov kev ntsuas cua daj cua dub siab tshaj plaws (ASTM E1996 Level D).
