Silicone Sealant nyob rau hauv IGU Secondary Seal: Dab tsi Tiag Tiag Ntev -Lub Sijhawm Insulating Glass Performance
Jul 02, 2026
Tso lus
Nyob rau hauv insulating iav chav tsev (IGU) ntau lawm, feem ntau cov xim yog muab tso rau hauv iav zoo, spacer systems, los yog ntau lawm cov khoom. Tab sis nyob rau hauv lub sijhawm ntev - kev ua tau zoo, muaj ib feem uas ntsiag to txiav txim siab seb IGU yuav kav li 5 xyoo lossis 25 xyoo:
Secondary silicone sealant.
Lub foob thib ob no tsis pom nyob rau hauv cov khoom kawg. Thaum lub tsev tau teeb tsa, tsis muaj tus neeg siv kawg yuav pom nws dua. Tab sis yog tias nws ua tsis tiav, qhov tshwm sim yog tam sim ntawd -fogging, roj to, condensation, thiab ua tiav kev ua haujlwm ntawm rwb thaiv tsev.
Rau IGU cov tuam txhab thiab pab pawg muag khoom, qhov no tsis yog qhov kev txiav txim siab dav dav ntawm cov khoom sib khi. Nws yog qhov kev txiav txim siab tseem ceeb ntawm cov khoom lag luam.
1. Lub luag haujlwm tiag tiag ntawm kev foob thib ob hauv IGU systems
Ib chav iav insulating ib txwm siv dual - kaw lus:
Thawj foob (butyl sealant)
Siv rau ntawm lub spacer
Lub ntsiab barrier rau roj thiab ya raws
Muab qhov pib airtightness
Secondary foob (silicone sealant lossis polysulfide / polyurethane systems)
Structural reinforcement txheej
Muab mechanical zog
Khaws lub sij hawm ntev - durability
Tiv thaiv thawj lub foob los ntawm kev ntxhov siab sab nraud
Hauv cov ntsiab lus yooj yim:
👉 Lub foob tseem ceeb ua kom muaj roj.
👉 Lub foob thib ob ua kom lub cev ua ke.
Yog tias tsis muaj kev ntseeg siab thib ob, IGU qauv yuav maj mam poob txawm tias thawj lub foob tsis zoo.
2. Vim li cas silicone yog dav siv los ua lwm yam sealant
Ntawm cov txheej txheem sib txuas sib txawv, silicone sealant tau dhau los ua qhov kev xaiv zoo tshaj plaws hauv ntau cov kab IGU niaj hnub no, tshwj xeeb tshaj yog rau siab -kev ua tau zoo architectural iav.
Cov laj thawj yog cov tswv yim, tsis yog theoretical:
(1) Ntev -lub sij hawm elasticity
IGUs tas li kev paub:
Thermal expansion
Cua load siab
Lub tsev txav
Silicone tswj kev yoog raws ntau xyoo dhau los yam tsis ua nkig.
(2) Kev tiv thaiv huab cua zoo heev
Secondary seals raug rau:
UV hluav taws xob
Los nag thiab av noo
Kub caij tsheb kauj vab
Silicone tswj kev ruaj ntseg nyob rau hauv ntev - sab nraum zoov raug zoo dua li ntau cov organic sealants.
(3) Kev txhawb nqa kev ncaj ncees
Txawm hais tias tsis yog lub hauv paus gas barrier, silicone muab:
Spacer adhesion zog
Ntug stability
Load faib kev txhawb nqa
Qhov no yog qhov tseem ceeb rau cov iav loj thiab daim ntawv thov façade.
3. Qhov twg IGU systems yeej ua tsis tiav hauv cov haujlwm tiag tiag
Thaum insulating iav units tsis ua hauj lwm nyob rau hauv lub tshav pob, lub hauv paus ua rau yog feem ntau traced rov qab mus rau lwm yam kev foob cov teeb meem:
(1) Gas to thaum lub sij hawm
Kev poob ntawm argon lossis krypton roj ua rau:
Txo cov rwb thaiv tsev ua haujlwm
Kev siv hluav taws xob ntau ntxiv
Fogging ntawm panes
Qhov no feem ntau txuas rau micro- tsis ua haujlwm hauv lub kaw lus kaw.
(2) Ntug foob degradation
Kev raug UV thiab qhov kub thiab txias tuaj yeem ua rau:
foob tawg
Poob ntawm adhesion rau spacer
Maj mam dej vapor ingress
Thaum ya raws nkag mus, IGU kev ua tau zoo poob mus tas li.
(3) Delamination ntawm iav ntug system
Hauv cov xwm txheej hnyav:
Secondary foob cais los ntawm iav los yog spacer
Cov qauv kev ncaj ncees raug cuam tshuam
Tag nrho IGU yuav tsum tau hloov
Qhov no yog qhov siab -tus nqi tsis ua haujlwm nyob rau hauv façade systems.
4. Silicone vs polysulfide vs polyurethane hauv IGU cov ntsaws ruaj ruaj
Thaum silicone yog dav siv, nws tsis yog tib txoj kev xaiv. Kev txiav txim siab yuav khoom feem ntau suav nrog kev sib piv peb lub hauv paus loj:
Silicone sealant
Lub zog:
Zoo heev UV tsis kam
Ntev -lub sij hawm elasticity
Muaj zog huab cua durability
Kev ua haujlwm ruaj khov hauv kev siv façade
Kev txwv:
Tus nqi siab dua
Yuav tsum muaj kev tswj xyuas kom meej rau kev siv IGU
Polysulfide sealant
Lub zog:
Zoo gas barrier zog
Dav siv nyob rau hauv tsoos IGU ntau lawm
Tus nqi - siv tau hauv ntau daim ntawv thov
Kev txwv:
Tsawg UV tsis kam piv rau silicone
Kev laus kev ua tau zoo nyob ntawm ntau yam ntawm formulation
Polyurethane sealant
Lub zog:
Muaj zog adhesion
Zoo mechanical zog
Siv dav hauv qee qhov kev lag luam IGU
Kev txwv:
UV rhiab heev
Muaj peev xwm ntev -degradation nyob rau hauv ib puag ncig raug
Nyob rau hauv niaj hnub siab - kev ua tau zoo ntawm cov kab hlau rhuav phab ntsa, silicone yog qhov xav tau ntau dua qhov twg ntev - lub sij hawm durability thiab huab cua raug qhov tseem ceeb.
5. Qhov tseem ceeb ntawm kev xaiv silicone sealant thib ob
Rau IGU cov tuam txhab thiab pab pawg neeg yuav khoom, qhov kev ua tau zoo sib txawv tsis yog txiav txim los ntawm "silicone vs non-silicone" ib leeg, tab sis los ntawm kev tsim qauv zoo thiab cov txheej txheem sib raug.
Cov yam tseem ceeb muaj xws li:
1. Adhesion stability rau iav thiab spacer
Secondary foob yuav tsum tuav ntev - lub sij hawm sib txuas rau:
Float iav
Coated iav
Aluminium spacers
Warm ntug systems
Tsis zoo adhesion coj ncaj qha mus rau ntug tsis ua hauj lwm.
2. Tsawg permeability kev ua tau zoo
Txawm hais tias lub foob thawj tswj hwm feem ntau cov roj khaws cia, lub foob thib ob yuav tsum tseem txhawb nqa lub kaw lus nruj nyob rau hauv ntev - lub sij hawm kev ntxhov siab.
3. Thermal cycling tsis kam
IGUs nyob rau hauv ib puag ncig tiag tiag ntsej muag:
Hnub / hmo ntuj kub viav vias
Lub caij ntuj sov variation
Ceev ceev thermal shocks
Sealant yuav tsum nyob ruaj khov nyob rau hauv rov nthuav dav thiab contraction cycles.
4. Compatibility nrog IGU ntau lawm kab
Hauv kev tsim khoom lag luam, sealant yuav tsum sib haum nrog:
Automated dispensing systems
Curing ceev xav tau
Kab ntau lawm efficiency
Spacer cov ntaub ntawv thiab coatings
5. Batch-rau-batch sib xws
Rau IGU cov tuam txhab, qhov sib xws yog feem ntau tseem ceeb tshaj qhov ua tau zoo tshaj plaws. Variations coj mus rau:
Ntau lawm instability
Kev sib txawv ntawm cov khoom sib txawv
Nce tus nqi tsis lees paub
6. Cov txheej txheem tsim khoom tseem ceeb npaum li qhov kev xaiv khoom
Txawm tias siab - zoo silicone tuaj yeem ua tsis tau yog tias cov txheej txheem tsim khoom IGU tsis raug tswj kom raug.
Cov teeb meem kev tsim khoom muaj xws li:
(1) Qhov chaw paug
Cov iav los yog spacer ntos paug nrog roj, plua plav, los yog ya raws txo adhesion zog heev.
(2) Tsis yog sealant thickness
Nyias dhau → kev txhawb nqa tsis txaus
Cov tuab tuab heev → kev kho tsis sib xws thiab kev ntxhov siab
(3) Kev kho tsis raug
Kub thiab av noo ncaj qha cuam tshuam rau crosslinking thiab kev ua haujlwm kawg.
(4) Kev sib xyaw ua ke lossis kev xa tawm tsis raug
Hauv kev siv tshuab tsis siv neeg, qhov sib piv tsis raug lossis tsis zoo sib xyaw ua rau cov chaw tsis muaj zog hauv lub foob.
7. Pab pawg neeg yuav khoom yuav tsum ntsuas IGU silicone sealants li cas
Hauv kev txiav txim siab yuav khoom tiag tiag, cov ntaub ntawv thev naus laus zis yog qhov tseem ceeb.
Kev ntsuam xyuas kom raug yuav tsum muaj xws li:
IGU-kev sib tw tshwj xeeb
Adhesion Performance Reports
UV thiab thermal aging data
Gas permeability txhawb kev ua haujlwm
Industrial kab compatibility validation
Ntev - lub sij hawm façade daim ntawv thov siv siv
Feem ntau, cov ntaub ntawv ua haujlwm tiag tiag yog qhov tseem ceeb dua li cov lej kuaj ib leeg.
8. Qhov twg silicone thib ob foob feem ntau siv
Silicone-raws li cov tshuab foob thib ob tau siv dav hauv:
Siab -nce phab ntsa IGUs
Commercial tsev façades
Zog-nqi qis-E iav units
Loj architectural glazing systems
Cov qauv glazing IGU sib dhos
Cov ntawv thov no txhua tus qhia ib qho yuav tsum tau ua: ntev -lub sij hawm ruaj khov nyob rau hauv ib puag ncig tsis tu ncua.
Xaus
Hauv cov iav insulating, lub foob thib ob tsis yog cov khoom siv tom qab- nws yog cov qauv kev ruaj ntseg uas txiav txim siab ntev - lub sijhawm ua haujlwm.
Silicone sealant, thaum tsim kom raug thiab raug muab tso rau hauv IGU ntau lawm, muab qhov sib npaug ntawm elasticity, durability, thiab huab cua tsis kam uas yog qhov tseem ceeb rau niaj hnub architectural glazing.
Rau pab pawg neeg yuav khoom thiab IGU cov tuam txhab, qhov tseem ceeb ntawm kev tshem tawm yog yooj yim:
Koj tsis yog xaiv ib lub sealant xwb.
Koj tab tom xaiv lub sijhawm ntev - kev ntseeg siab ntawm txhua chav iav tsim.
Vim tias ib zaug IGU tawm ntawm lub Hoobkas thiab nkag mus rau hauv lub tsev façade, kev ua tsis tiav yog tsis muaj teeb meem khoom siv ntxiv lawm - nws dhau los ua qhov system - tus nqi dav.
