Puas yog laminated iav tawg los yog tawg?

Laminated iav yog hom iav kev nyab xeeb uas tau siv dav hauv ntau daim ntawv thov. Tsis zoo li cov iav tempered los yog iav annealed, laminated iav yog tsim los tiv thaiv kev tawg thiab muab kev tiv thaiv ntau ntxiv tiv thaiv kev tawg, xwm txheej, thiab huab cua huab cua. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov khoom thiab cov yam ntxwv ntawm cov iav laminated, nkag siab tias nws txawv li cas ntawm lwm hom iav, thiab sib tham txog nws lub peev xwm los tiv thaiv kev tawg lossis tawg.

Dab tsi yog laminated iav?

Laminated iav yog cov qauv zoo li cov xuab zeb uas muaj ob lossis ntau txheej ntawm cov iav sib txuas ua ke nrog ib qho interlayer. Qhov interlayer no feem ntau yog tsim los ntawm polyvinyl butyral (PVB) los yog ethylene-vinyl acetate (EVA), uas muaj qhov pom kev pom tseeb thiab muaj zog tensile siab. Cov iav txheej tuaj yeem sib txawv hauv cov tuab, thiab cov interlayer ua raws li cov nplaum, tuav lawv ua ke txawm tias tawg.

Kev nyab xeeb nta ntawm laminated iav

Ib qho ntawm cov laj thawj tseem ceeb ntawm laminated iav yog siv dav hauv ntau daim ntawv thov yog nws qhov tshwj xeeb kev nyab xeeb. Thaum tawg, cov iav fragments nyob rau hauv interlayer, tiv thaiv lawv los ntawm kev raug mob los yog nkag mus rau hauv lub iav. Cov cuab yeej no ua rau cov iav laminated yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas muaj kev nyab xeeb yog qhov kev txhawj xeeb tseem ceeb, xws li lub tsheb cua, lub tsev facades, thiab iav railings.

Cracking vs. tawg

Tam sim no, cia peb hais cov lus nug ntawm tes: puas laminated iav tawg los yog tawg? Cov lus teb yog me ntsis nuanced. Laminated iav yog tsim los tiv thaiv kev tawg, uas txhais tau hais tias nws tseem nyob ruaj khov txawm tias muaj zog tseem ceeb rau nws. Txawm li cas los xij, nws tseem tuaj yeem tawg hauv qee qhov xwm txheej.

Cracking nyob rau hauv laminated iav

Txawm hais tias laminated iav yog inherently resistant rau cracking piv rau lwm hom iav, nws tsis yog tag nrho. Kev tawg tuaj yeem tshwm sim hauv cov iav laminated vim muaj ntau yam laj thawj:

1. Kev cuam tshuam: Ib qho kev cuam tshuam muaj zog, xws li cov khoom hnyav poob rau ntawm iav lossis kev sib tsoo, tuaj yeem ua rau tawg ntawm cov iav laminated. Txawm li cas los xij, tsis zoo li cov iav tsoos, cov kab nrib pleb tsis tshua muaj peev xwm nthuav tawm thiab cuam tshuam cov qauv kev ncaj ncees ntawm cov iav.

2. Kev ntxhov siab ntau: Kev ntxhov siab ntau dhau ntawm cov ntsiab lus tshwj xeeb ntawm cov iav, xws li nyob ib ncig ntawm cov npoo los yog vim kev teeb tsa tsis raug, tuaj yeem ua rau tawg. Qhov kev ntxhov siab no tuaj yeem tshwm sim los ntawm thermal expansion thiab contraction, cua loads, los yog lwm yam ib puag ncig.

3. Kev tsim khoom tsis xws luag: Txawm hais tias tsis tshua muaj, kev tsim cov khoom tsis xws luag hauv cov iav los yog cov khoom siv interlayer tuaj yeem ua rau cov chaw tsis muaj zog lossis tsis zoo uas yuav ua rau tawg.

Sattering nyob rau hauv laminated iav

Thaum tawg tuaj yeem tshwm sim hauv cov iav laminated, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov iav yog tsim los tiv thaiv kev tawg. Tsis zoo li tempered iav, uas shatters rau hauv me me, dull-edged daim, laminated iav nyiam tuav ua ke thaum tawg vim yog interlayer. Lub interlayer ua raws li kev thaiv, ua kom cov khoom tawg ua ke thiab tiv thaiv lawv los ntawm kev sib cais lossis poob tawm.

Cov txiaj ntsig ntawm laminated iav

Sib nrug los ntawm nws cov yam ntxwv kev nyab xeeb, laminated iav muaj ntau yam txiaj ntsig uas ua rau nws nyiam xaiv hauv ntau daim ntawv thov:

1. Lub suab rwb thaiv tsev: Lub interlayer hauv cov iav laminated pab ua kom lub suab sib kis tau zoo, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau thaj chaw uas xav tau kev txo suab nrov, xws li chaw ua haujlwm, tsev, thiab tsev kho mob.

2. Kev tiv thaiv UV: Cov iav laminated tuaj yeem thaiv qhov teeb meem ntawm ultraviolet (UV) hluav taws xob ntau, uas tuaj yeem ua rau cov rooj tog zaum, cov duab kos duab, thiab cov flooring hauv lub sijhawm. Qhov no ua rau nws nrov rau qhov rais lossis iav qhov chaw raug tshav ntuj ncaj qha.

3. Kev ruaj ntseg: Kev tiv thaiv kom tawg thiab lub zog ntxiv los ntawm interlayer ua rau cov iav laminated yog ib qho khoom muaj nqis hauv cov ntawv thov kev ruaj ntseg yog qhov tseem ceeb, xws li cov tsev txhab nyiaj, cov khw muag khoom kim heev, thiab cov tsev cia puav pheej.

Xaus

Hauv kev xaus, thaum laminated iav yog tsim los tiv thaiv kev tawg, nws tsis yog tag nrho impervious rau tawg. Cov kev cuam tshuam muaj zog, kev ntxhov siab ntau, thiab kev tsim khoom tsis zoo tuaj yeem ua rau tawg ntawm cov iav laminated, txawm hais tias lawv tsis tshua muaj kev cuam tshuam rau tag nrho cov qauv kev ncaj ncees ntawm cov iav. Txawm li cas los xij, laminated iav tseem yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas muaj kev nyab xeeb, kev ruaj ntseg, thiab lub suab rwb thaiv tsev yog qhov tseem ceeb. Nws muaj peev xwm tuav ua ke thaum tawg thiab muab kev tiv thaiv UV hluav taws xob ua rau nws muaj ntau yam khoom siv thiab muaj txiaj ntsig hauv ntau yam lag luam.
