Laminated iav yog ib hom iav kev nyab xeeb uas tau ua los ntawm ob los yog ntau dua li ntawm daim iav annealed iav los yog tempered iav koom ua ke los ntawm PVB (polyvinyl butyl) interlayer.
Rau PVB zaj duab xis, nws muaj huab cua tiv thaiv siab thiab muaj zog muaj peev xwm ua tau zoo, thiab tuaj yeem sib raug zoo tag nrho rau nws cov iav thaum lub txheej txheem ntau lawm. Tom qab lub laminated iav tsim, iav tuaj yeem muaj qhov cuam tshuam muaj zog thiab muaj zog nkag tau zoo. Yog li ntawd, tom qab iav iav puas, nws tawg tsam tseem tuaj yeem ua rau zaj duab xis hauv nws, yog li kom zam dhau qhov teeb meem ntawm cov iav tawg. Thaum lub sij hawm teeb tsa ntawm cov txheej nruab nrab, nws cov tuab yuav ncaj qha cuam tshuam rau qhov kev hloov quab yuam, uas muaj qhov ua kom tau zoo los tiv thaiv qhov cuam tshuam.
Qhov ntau dua qhov tuab, qhov siab dua qhov kev cuam tshuam nws tuaj yeem tiv taus, thiab cov tuab ntawm txheej nruab nrab yog feem ntau ob npaug, uas tuaj yeem txhim kho qhov kev cuam tshuam los ntawm 2 mus rau 3 zaug. Nyob rau hauv tus txheej txheem ntawm xaiv laminated PVB zaj duab xis, nws yuav tsum ua haujlwm nruj me ntsis raws li" Kev Qhia Tshwj Xeeb rau Daim Ntawv Thov ntawm Architectural Glass" ;. Rau qee qhov tshwj xeeb ntawm daim iav laminated hauv kev siv cov txheej txheem, nruj me ntsis raws li zaj duab xis tuab ntawv yuav tsum tau ua, siv. Hauv cov cai, rau qee lub iav vov tsev lossis rau kev siv qee cov iav saum toj, nws yog qhov yuav tsum tau siv cov iav laminated. Nyob rau tib lub sijhawm, thaum siv laminated iav, cov tuab ntawm zaj duab xis yuav tsum ≥0.38mm, uas tuaj yeem muab ntau ntxiv los ntawm cov zauv. Qhov loj dua thaj tsam, Lub thickness tau tsim nyog nce. Rau kev siv ntawm cov iav pem teb, nws kuj yog qhov yuav tsum tau siv cov iav laminated, thiab rau kev siv cov iav taw tes rau hauv pem teb, nws yog qhov yuav tsum tau siv tempered laminated iav. Thaum siv cov pem teb laminated iav, lub thickness ntawm nws ib daim ntawv yuav tsum yog nruab nrab ntawm 3 hli, thiab cov tuab ntawm sab hauv laminated zaj duab xis yuav tsum siab tshaj 0.76 hli.
Hauv kev xaiv cov txheej txheem tshwj xeeb, txhawm rau txhawm rau txhawm rau txhawm rau txuas ntawm lub khob thiab cov zaj duab xis, feem ntau, qhov tuab tuab ntawm PVB zaj duab xis xav tau 0.38 hauv cov txheej txheem laminated zoo tib yam iav. Thaum tus thawj iav yog siab tshaj 8mm, lub thickness ntawm PVB zaj duab xis xav tau siab tshaj 0.76mm. Rau cov iav tempered, thaum lub thickness ntau dua 8mm, qhov tseeb tuab ntawm PVB xav tau ntau dua 1.14 hli. Rau qee qhov vaj huam sib luag nrog qhov loj qhov tseeb qhov muaj peev xwm thiab kev xav txog kev nyab xeeb thaum siv, cov tuab ntawm zaj duab xis yuav tsum nce ntau li ntau tau.
