Classification ntawm laminated iav

General civil tempered iav yog tsim los ntawm cov txheej txheem kev kho cua sov kom muaj zog ntawm cov iav zoo tib yam los ntawm 3-5 zaug, thiab tuaj yeem tiv taus qhov cuam tshuam sab nraud lossis qhov kub thiab txias hloov ntawm qee lub zog yam tsis muaj kev tawg. Txawm hais tias tawg, tag nrho cov iav tau tawg rau hauv me me obtuse lub kaum sab xis zoo ib yam li cov duab honeycomb, uas tsis yooj yim rau kev ua phem rau tib neeg thiab yog li muaj qee qhov kev nyab xeeb. Tempered iav tsis tuaj yeem txiav thiab yuav tsum tau txiav kom loj ua ntej tempering, nrog rau tus yam ntxwv ntawm tus kheej tawg. Raws li kev siv sib txawv, tempered iav tuaj yeem muab faib ua ntau hom xws li iav tempered, semi tempered iav, thaj tsam tempered iav, tempered iav, thiab iav tempered iav.
Laminated iav, raws li hom iav kev nyab xeeb, yuav tsis tsim cov khoom tawg yooj yim uas tuaj yeem ua mob rau tib neeg tom qab tawg los ntawm kev cuam tshuam vim kev sib raug zoo ntawm PVB zaj duab xis sandwiched ntawm nws ob lub iav zoo tib yam. Nyob rau tib lub sijhawm, lub suab rwb thaiv tsev thiab lub hnub ci tswj cov khoom ntawm nws cov PVB nruab nrab zaj duab xis ua rau nws yog hom tshiab ntawm cov khoom siv hauv tsev nrog kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: kev siv cov iav laminated tsis tuaj yeem tsuas yog cais cov 1000-2000 Hz. coincidence suab nrov uas tuaj yeem nkag mus rau iav zoo tib yam, tab sis kuj thaiv ntau dua 99% ntawm cov kab hluav taws xob ultraviolet thiab nqus cua sov hauv infrared spectrum. Raws li cov iav laminated uas ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hauv tsev tshiab, nws yuav tsum ua lub luag haujlwm loj hauv kev siv iav kev nyab xeeb.
