1. Txheeb xyuas cov kev xav tau thiab cov qauv kev ua tau zoo
Kauj ruam thawj zaug yog txhais cov xwm txheej hnyav uas yuav tsum tau ntsib thiab cov hom phiaj kev ua tau zoo. Cov yam ntxwv tseem ceeb feem ntau suav nrog:
- Lub zog cua (qhov chaw nyob ntawm ntug dej hiav txwv / cov tsev siab = lub zog cua siab).
- Qhov kub thiab qhov pheej hmoo ntawm kev poob siab thermal (qhov kub sib txawv tam sim ntawd, piv txwv li iav raug tshav ntuj thiab tom qab ntawd los nag).
- Kev raug UV ntev (kev pheej hmoo ntawm kev daj ntawm cov txheej interlayer, kev ua haujlwm ntawm cov txheej txheej txo qis).
- Kev pheej hmoo ntawm kev cuam tshuam (nag xob nag cua, ceg ntoo, cov khoom me me, kev ua phem, kev ua ub ua no ntawm tib neeg).
- Cov kev cai rau kev nyab xeeb (iav yuav tsum tawg ua tej daim me me lossis tseem zoo li qub thaum tawg).
- Lub hom phiaj rau kev rwb thaiv cua sov, kev txo suab nrov, thiab kev tswj lub teeb ci ntsa iab (tshwj xeeb tshaj yog rau cov ntsej muag).
Nyob rau theem no, cov qauv siv feem ntau kuj raug txiav txim siab, piv txwv li hais txog iav kev nyab xeeb, kev sim kev cuam tshuam, lossis kev ua tau zoo ntawm laminate - uas yog qhov tseem ceeb uas yuav tsum tau siv los ua cov qauv los ntawm cov chaw tsim khoom thiab cov neeg cog lus.

2. Xaiv cov khoom siv hauv paus: cov iav ntab zoo
Feem ntau ntawm cov iav vaj tse niaj hnub no yog ua los ntawm cov iav ntab (cov iav ua los ntawm cov tin uas yaj). Rau kev siv sab nraum zoov heev, xaiv cov iav ntab uas muaj:
- Zoo optical zoo (tsawg distortion).
- Thickness raws li qhov hnyav (feem ntau 6 hli, 8 hli, 10 hli, 12 hli lossis ntau dua; rau cov vaj huam sib luag loj nws tuaj yeem tuab dua).
- Tsis muaj qhov tsis zoo (ua npuas, muaj cov khoom me me, khawb), vim tias qhov tsis zoo me me tuaj yeem yog qhov pib ntawm kev tawg.
Qhov zoo ntawm cov khoom siv hauv paus yuav cuam tshuam rau qhov kawg, tshwj xeeb tshaj yog tom qab ua tiav rau hauv tempered / laminated.

4. Kev txhawb nqa thawj zaug: tempered lossis cua sov-strengthened
Yuav kom tiv taus cua hlob, kev cuam tshuam, thiab kev poob siab thermal, iav feem ntau yog txhawb nqa nrog ib qho ntawm cov txheej txheem hauv qab no:
a) Tempered (iav tempered / iav toughened)
Iav raug cua sov kom ze rau nws qhov chaw mos thiab tom qab ntawd txias sai sai (quenched), tsim kev ntxhov siab compressive rau ntawm qhov chaw. Qhov tshwm sim:
- Muaj zog dua li cov iav ib txwm muaj.
- Ua kom muaj zog dua rau thermal shock.
- Thaum nws tawg, nws tawg ua tej daim me me (muaj kev nyab xeeb dua li tej daim ntse).
Qhov tsis zoo: thaum tawg lawm, lub vaj huam sib luag tuaj yeem vau tag (tsis lo ua ke), yog li rau thaj chaw saum toj nws feem ntau yog ua ke nrog laminate.
b) Kub-strengthened
Zoo ib yam li tempered tab sis txias qeeb dua. Muaj zog tshaj plaws hauv nruab nrab:
- Muaj zog dua li cov iav ib txwm muaj, tab sis qis dua cov iav tempered.
- Tus qauv tawg feem ntau yog "loj dua" dua li tempered.
Rau qee qhov kev siv, kev siv cua sov los ua kom muaj zog yog xaiv los txo qhov kev pheej hmoo ntawm kev cuam tshuam ntawm qhov muag thiab ua kom lub kaw lus laminate ruaj khov.

5. Lamination: ua rau lub iav "tsis hloov pauv" thaum tawg.
Rau huab cua hnyav thiab kev nyab xeeb, iav laminated yog qhov kev daws teeb meem pom zoo tshaj plaws. Lamination yog ua tiav los ntawm kev sib koom ua ke ob (lossis ntau dua) daim iav siv ib txheej interlayer thiab tom qab ntawd ua tiav lawv nrog cua sov thiab siab (autoclaving).
Cov kev xaiv sib xyaw ua ke:
– PVB (Polyvinyl Butyral): zoo rau kev nyab xeeb thiab suab, siv dav.
– EVA (Ethylene-Vinyl Acetate): feem ntau siv rau cov hom phiaj tshwj xeeb, suav nrog cov ntawv thov kho kom zoo nkauj; kev xaiv EVA zoo yog qhov tseem ceeb rau kev tiv taus UV.
– SGP/ionoplast (piv txwv li, SentryGlas): Muaj zog heev thiab nruj, zoo heev rau cov ru tsev, cov laj kab tsis muaj thav duab, thiab cov chaw muaj kev pheej hmoo siab. Ruaj khov rau hauv qhov kub thiab txias siab dua thiab av noo.
Rau cov xwm txheej sab nraum zoov heev (UV siab, cua sov, av noo), kev xaiv cov txheej interlayer yog qhov tseem ceeb heev kom nws tsis yooj yim tawg, tsis daj sai, thiab tseem ruaj khov.
Cov kev sib xyaw ua ke uas siv ntau: tempered + tempered laminated lossis heat-strengthened laminated nyob ntawm seb xav tau dab tsi.

6. Chav Iav Insulated (IGU): tiv taus cua sov, txuag hluav taws xob, txo cov dej noo
Yog tias iav siv rau qhov rais lossis phab ntsa ntaub thaiv, nws feem ntau ua rau ob npaug lossis peb npaug glazing: ob daim iav sib cais los ntawm lub spacer thiab kaw, tsim cov qhov puv nrog cua qhuav lossis roj (argon / krypton).
Nws qhov zoo:
- Kev rwb thaiv cua sov ntau dua (zoo dua thiab txuag hluav taws xob).
- Txo qhov kev pheej hmoo ntawm kev nthwv dej.
- Kev tiv thaiv suab zoo dua.
Rau huab cua hnyav heev, qhov zoo ntawm cov sealant thiab desiccant (dej nqus pa hauv lub spacer) yog qhov tseem ceeb rau lub neej ntawm IGU, tshwj xeeb tshaj yog nyob rau hauv huab cua kub-av noo lossis thaj chaw uas muaj qhov sib txawv ntawm qhov kub thiab txias.

7. Txheej rau UV, cua sov thiab corrosion tsis kam
Yuav kom ua rau lub iav tiv taus lub hnub thiab huab cua, feem ntau yuav ntxiv ib txheej txheej:
– Txheej Low-E: tiv thaiv cov hluav taws xob infrared, txo cov cua sov nkag/tawm. Haum rau kev txuag hluav taws xob.
- Txheej txheej tswj lub hnub ci: tswj lub hnub ci kub (qis dua SHGC), txo qhov kaj ntsa iab.
- Tiv thaiv kev cuam tshuam / tiv thaiv kev ci ntsa iab: pab nrog qee qhov pom kev.
- Txheej txheej ntxuav nws tus kheej: ib txheej txheej photocatalytic uas pab rhuav tshem cov av organic thiab ua rau kev ntxuav yooj yim dua.
Tseem Ceeb: Qee cov txheej txheej yuav yooj yim rau cov chaw ntsev (thaj chaw ntug dej hiav txwv) lossis qee cov tshuaj ntxuav. Xyuas kom tseeb tias cov txheej txheej raug xaiv kom haum rau qhov chaw ib puag ncig thiab muab tso rau ntawm qhov chaw raug (piv txwv li, qhov chaw ntawm qhov chaw 2 lossis 3 ntawm IGU).

8. Tsim kev teeb tsa: txawm tias iav muaj zog tuaj yeem ua tsis tiav yog tias lub kaw lus tsis raug.
Cov iav sab nraum zoov tsis ua haujlwm ib leeg xwb; nws ua haujlwm ua ke nrog lub kaw lus ntawm cov thav duab thiab cov khoom siv foob. Rau huab cua hnyav heev:
– Siv ib lub gasket/setting block uas tsim nyog kom lub nra tsis txhob nias ncaj qha rau ntawm ntug ntawm lub iav.
- Xyuas kom tseeb tias muaj kev kam rau siab (thermal) ntawm lub thav duab.
– Xaiv cov tshuaj sealant uas sib xws nrog cov interlayers thiab coatings (tshwj xeeb tshaj yog rau laminated thiab structural glazing).
- Ua tib zoo saib xyuas cov txheej txheem ntws dej ntawm qhov profile kom dej tsis txhob nkag thiab ua rau lub foob puas.
Ntau zaus ntawm "iav tawg" yeej yog los ntawm kev teeb tsa uas tsim kev ntxhov siab ntxiv lossis tso cai rau dej nkag mus rau hauv thaj chaw uas yuav tsum tsis txhob ntub dej.
