Laminated iav, tseem hu ua iav kev nyab xeeb, yog ib hom iav uas tsim los ntawm kev sib txuas ob lossis ntau txheej iav ua ke nrog cov txheej txheem hloov pauv, feem ntau yog ua los ntawm polyvinyl butyral (PVB). Qhov no interlayer tuav cov iav ua ke nyob rau hauv qhov kev tshwm sim ntawm breakage, muab kev ruaj ntseg thiab kev ruaj ntseg ntau dua piv rau cov tsoos annealed iav.
Cov txheej txheem ntawm kev tsim cov iav laminated suav nrog kev tso cov interlayer ntawm cov iav txheej thiab ua rau lub rooj sib txoos kom sov thiab siab hauv cov txheej txheem hu ua lamination. Qhov no ua rau muaj zog, ruaj khov khoom siv uas muaj ntau yam txiaj ntsig thiab kev siv.
Ib qho ntawm qhov zoo ntawm cov iav laminated yog nws cov yam ntxwv kev nyab xeeb. Thaum lub iav raug cuam tshuam, lub interlayer tuav cov khoom tawg ua ke, tiv thaiv lawv los ntawm kev tawg thiab txo kev raug mob. Qhov no ua rau cov iav laminated yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas muaj kev nyab xeeb yog qhov tseem ceeb, xws li hauv tsheb cua, lub tsev facades, thiab overhead glazing.
Ntxiv nrog rau kev nyab xeeb, laminated iav kuj muaj kev ruaj ntseg zoo dua. Cov khaubncaws sab nraud povtseg muab kev tiv thaiv tawm tsam yuam kev nkag, ua rau nws nyuaj rau cov neeg nkag mus rau hauv lub khob. Qhov no ua rau cov iav laminated yog qhov kev xaiv nrov rau siv rau hauv qhov rais thiab qhov rooj hauv cov tsev nyob thiab kev lag luam, nrog rau cov chaw muaj kev nyab xeeb siab xws li tsev txhab nyiaj thiab tsoomfwv cov tsev.
Lwm qhov tseem ceeb ntawm cov iav laminated yog nws lub peev xwm los thaiv cov teeb meem ultraviolet (UV) hluav taws xob. Lub interlayer hauv laminated iav tuaj yeem tsim los lim tawm UV rays zoo, pab tiv thaiv cov chaw sab hauv thiab cov neeg nyob hauv kev puas tsuaj los ntawm lub hnub ntev. Qhov no ua rau cov iav laminated yog qhov kev xaiv tsim nyog siv rau hauv qhov rais thiab skylights, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj hnub ci siab.
Tsis tas li ntawd, laminated iav muaj lub suab rwb thaiv tsev, pab txo cov suab nrov ntawm lub qhov rais thiab lwm qhov chaw glazed. Qhov no tuaj yeem ua rau muaj kev thaj yeeb nyab xeeb thiab nyob hauv tsev, ua rau nws yog qhov kev xaiv zoo rau kev siv hauv vaj tse, chaw ua haujlwm, thiab lwm qhov chaw uas tswj lub suab nrov yog qhov tseem ceeb.
Lub versatility ntawm laminated iav txuas mus rau nws cov hniav muaj peev xwm. Lub interlayer tuaj yeem hloov kho nrog ntau yam xim, qauv, thiab textures, tso cai rau tsim muaj tswv yim tsim muaj peev xwm hauv kev siv architectural. Cov iav laminated tuaj yeem siv los tsim qhov pom kev zoo nkauj xws li cov khoom siv kho kom zoo nkauj, balustrades, thiab kos npe, ntxiv cov txiaj ntsig zoo nkauj rau sab hauv thiab sab nrauv.
Txheej txheem ntawm lamianted iav:
Txiav → tu → ziab → Laminating → cua sov → Roller siab → Reheating → Reroller siab → kub thiab siab siab hauv autoclave (Edging, tu) → Tshuaj xyuas
Dab tsi yog qhov haujlwm ntawm auto-clave? Dab tsi yog Composit chamer (chav lamination)?
Lub luag haujlwm ntawm "composite chamber" hauv kev tsim cov sandwich yog laminate ob lossis peb daim iav ua ke nrog ib lossis ntau txheej ntawm PVB zaj duab xis. Yuav tsum muaj qhov kub, av noo thiab huv si hauv chav lamination.
Lub luag haujlwm ntawm autoclave yog tsim kom muaj qhov kub thiab txias, siab thiab sijhawm rau:
A. daws cov cua seem hauv cov txheej txheem degassing ntawm laminated iav;
B. Tso cai rau cov viscous ntws ntawm PVB zaj duab xis ntawm interlayers, thiab thaum kawg ua rau cov iav thiab PVB zaj duab xis lo ua ke;
C. Tiv thaiv lub tshav kub hloov mus rau nruab nrab ntawm kev nkag mus rau hauv lub ntug ntawm cov qhaub cij; Tom qab cua sov, siab thiab lub sijhawm, cov iav laminated yuav muaj qhov pom zoo thiab ua haujlwm zoo.
Dab tsi yog qhov kev sim boil rau laminated iav?
Cov qauv iav laminated yog vertically rau hauv lub tank ntawm 66 ± 3 degree C, thiab tom qab peb feeb, cov qauv raug tshem tawm sai sai ntawm lub tank thiab tam sim ntawd muab tso rau hauv lwm lub tank ntawm boiling dej rau 2 teev. Lub sij hawm muab tso rau yog xam los ntawm thaum cov dej kub nce mus txog boiling dej dua tom qab cov qauv muab tso rau hauv. Lub hom phiaj ntawm lub boiling test yog los soj ntsuam cov stability ntawm laminated iav nyob rau hauv kub thiab av noo tej yam kev mob.
Degumming yog dab tsi? Yuav ua li cas degumming tshwm sim?
Cov iav laminated tsim nyog yog kev sib khi nruj ntawm PVB zaj duab xis thiab iav, thiab yog ua los ntawm iav kev nyab xeeb nrog cov pob tshab zoo thiab kev ua haujlwm zoo tom qab kub thiab siab. Thaum lub iav laminated degummed, PVB zaj duab xis yog sib cais los ntawm iav thiab muaj qhov sib txawv. Tshwj xeeb tshaj yog nyob rau ntawm ntug, nws nyhav tshwm sim. Qhov tshwm sim degumming no yog tshwm sim los ntawm cov iav ntug tau raug rau qhov chaw ntub dej ntev ntev thiab tshwm sim los ntawm kev ya raws thiab huab cua huab cua.
Daim ntawv thov rau laminated iav yog dab tsi?
Laminated iav yog tsim rau lub qhov rooj, qhov rais, qab nthab, pem teb thiab partitions ntawm lub tsev vim nws muaj feem xyuam rau lub zog thiab kev nyab xeeb. Skylights nyob rau hauv industrial vaj tse; Lub qhov rais khw; Kindergartens, tsev kawm ntawv, gymnasiums, private tsev, villas, madhouses, banks, hniav nyiaj hniav kub khw, chaw xa ntawv, thiab lwm yam. khaws lub qhov rooj thiab qhov rais ntawm ib lub xyoo-laus vaj tse ntawm koj lub tuam txhab.
