Laminated iav yog dab tsi
Oct 25, 2022
Laminated iav yog ib qho ntawm cov khoom nrov tshaj plaws nyob rau hauv kev ua lag luam-thiab rau qhov laj thawj zoo. Nrog nws lub zog zoo tshaj plaws, ntau yam thicknesses thiab txheej txheej, thiab cov kev xaiv zoo nkauj tsis muaj qhov kawg, laminated iav yog qhov kev xaiv zoo tshaj plaws rau kev nyab xeeb-thawj thiab siv cov hniav zoo nkauj hauv txhua yam kev lag luam thiab kev siv hauv tsev.
Hais tias, laminated kev nyab xeeb iav tsis yog rau txhua tus. Txhawm rau pab koj txiav txim siab seb hom khoom iav no puas yog rau koj qhov project, peb tau muab cov lus qhia luv luv ua ke. Nyeem rau thaum peb piav qhia qee yam ntawm cov yam ntxwv tseem ceeb, suav nrog thaum siv nws thiab nws txawv li cas ntawm cov iav toughened.
Yuav ua li cas laminated iav?
Laminated iav yog tsim los ntawm adhering ob los yog ntau tshaj li niaj zaus nplooj ntawm iav nrog ib tug saj zawg zog PVB (polyvinyl butyl) interlayer. Qhov no yog ua tiav los ntawm cov txheej txheem cua sov thiab kev sib txuas uas txuas nrog cov txheej txheem sib txawv los tsim ib daim ntawv iav.
Qhov txiaj ntsig tseem ceeb ntawm hom iav no yog nws lub zog. Nws yog dav siv rau kev nyab xeeb thiab kev nyab xeeb lub hom phiaj, mus rau qhov chaw uas koj yuav nquag hnov nws hu ua "laminated kev ruaj ntseg iav". Vim tias VB cov khaubncaws sab nraud povtseg rau lub iav, yog tias lub iav tawg qee qhov, nws tseem yuav tuav hauv qhov chaw. Raws li ib qho ntxiv lawm, PVB interlayer ua rau lub iav nyuaj rau kev ua txhaum cai, txawm tias tawg.
Nws txawv li cas ntawm cov iav toughened?
Laminated thiab toughened iav yog ob qho kev xaiv rau kev nyab xeeb. Ob leeg tuaj yeem txiav, zoo li tus, thiab drilled (ua ntej toughening) kom haum rau txhua yam kev nyab xeeb-thawj daim ntawv thov. Tab sis toughened iav yog ua tiav txawv, thiab xws li, nws coj txawv txawv thaum tawg.
Toughened kev nyab xeeb iav yog tshav kub-kho tsis tau tsuas yog rau lub zog, tab sis kom ntseeg tau tias, yog hais tias tawg, lub iav shatters mus rau hauv heev me me daim. UK cov qauv kev nyab xeeb rau cov iav toughened hais tias lub iav yuav tsum tawg mus rau hauv qhov tsis ntau tshaj 5 hli dav. Qhov no ua kom cov khoom me me tsis ua rau raug mob hnyav, tsis zoo li cov shards loj.
Laminated kev ruaj ntseg iav yog ib yam li cov iav toughened. Txawm li cas los xij, nws tsis tas yuav dhau los ua "toughening" txheej txheem hauv kev tsim khoom. Hloov chaw, PVB interlayer khi cov iav ua ke, tuav lub vaj huam sib luag rau hauv qhov chaw thaum tawg thiab tiv thaiv kev raug mob hnyav.
Laminated thiab toughened iav kuj tuaj yeem ua ke rau lub vaj huam sib luag siab tshaj plaws.
Nrov siv rau laminated kev nyab xeeb iav
Cov txheej txheem ntawm laminating iav tau dav siv rau kev nyab xeeb daim ntaub ntawv txij li Henry Ford pib ntxiv nws rau Ford tsheb windscreens nyob rau hauv 1919. Niaj hnub no, laminated windscreens yog tus qauv haum rau lub tsheb thoob plaws lub ntiaj teb no.
Raws li kev siv hauv tsev lossis kev lag luam tsim, laminated iav cog qoob loo hauv txhua daim ntawv thov uas muaj kev nyab xeeb yog qhov tseem ceeb: balustrades rau balconies, pas dej da dej, thiab staircases; iav flooring; iav stair treads; iav canopies; iav muab faib phab ntsa; thiab qhov rais thiab qhov rooj ruaj ntseg. Qhov no yog ib qho pov thawj tsis yog rau lub zog ntawm cov khoom no, tab sis kuj nws versatility.
Kho kom zoo nkauj mesh iav
Laminating iav nrog coloured, ntaub los yog mesh interlayers kuj muab cov qauv tsim kom muaj tswv yim. Cov iav xim (feem ntau yog xiav, ntsuab, lossis grey) yog qhov nrov nrog cov xim ntxiv los ntawm kev siv cov xim iav los yog los ntawm kev ntxiv cov tinted PVB txheej. Peb feem ntau pom zoo rau tom kawg, raws li cov xim interlayer muab ntau yam xim thiab xim ntau dua li cov iav vaj huam sib luag.
Cov neeg tsim qauv kuj tuaj yeem siv frosting lossis sandblasting rau cov nyhuv zoo nkauj. Qhov no tuaj nyob rau hauv daim ntawv ntawm sandblasted PVB interlayer, uas tsim ib txheej ntawm kev ceev ntiag tug nyob rau hauv tej chaw xws li chav dej, private chaw ua hauj lwm, los yog txoj kev.
