1. Kev piav qhia txog cov iav rwb thaiv tsev
Iav rwb thaiv tsev yog ib hom iav txuag hluav taws xob uas tau siv dav hauv cov tsev ua haujlwm lag luam, cov khw loj, cov tsev nyob siab thiab lwm lub tsev. Nws muaj cov khoom rwb thaiv tsev kub thiab suab rwb thaiv tsev zoo heev thiab zoo nkauj thiab siv tau. Iav rwb thaiv tsev yog ua los ntawm ob (lossis ntau dua) daim iav sib txuas nrog cov spacers. Muaj ob hom kev sib khi tseem ceeb: txoj kev strip thiab txoj kev sib txuas kua nplaum. Tam sim no, ob lub foob hauv txoj kev sib txuas kua nplaum yog cov qauv sib khi feem ntau siv. Cov qauv yog raws li pom hauv Daim Duab 1: ob daim iav raug sib cais los ntawm cov spacers, thiab butyl sealant siv los kaw lub spacer thiab iav nyob rau pem hauv ntej.Sau sab hauv ntawm lub spacer nrog molecular sieve, thiab kaw qhov sib txawv ntawm ntug ntawm lub iav thiab sab nraud ntawm lub spacer nrog cov sealant thib ob.
Lub luag haujlwm ntawm thawj daim ntawv foob yog los tiv thaiv cov pa dej lossis cov pa roj inert kom tsis txhob nkag thiab tawm hauv qhov chaw. Feem ntau siv cov ntawv foob butyl vim tias qhov nrawm ntawm kev kis cov pa dej thiab qhov nrawm ntawm kev kis cov pa roj inert ntawm cov ntawv foob butyl qis heev. Txawm li cas los xij, cov ntawv foob butyl nws tus kheej muaj lub zog sib txuas qis thiab qhov elasticity qis, yog li cov qauv tag nrho yuav tsum tau kho nrog cov ntawv foob thib ob los txuas cov phaj iav thiab cov spacers ua ke. Thaum lub iav rwb thaiv tsev nyob hauv qab kev thauj khoom, ib txheej ntawm cov ntawv foob tuaj yeem tswj tau qhov zoo ntawm kev sib khi. Tib lub sijhawm, tag nrho cov qauv tsis cuam tshuam.

2. Hom tshuaj nplaum thib ob rau cov iav rwb thaiv tsev
Muaj peb hom tshuaj nplaum thib ob tseem ceeb rau cov iav rwb thaiv tsev: polysulfide, polyurethane thiab silicone. Daim Ntawv Teev 1 teev qee yam ntxwv ntawm peb hom tshuaj nplaum tom qab lawv kho tag.
Rooj 1 Kev sib piv ntawm cov yam ntxwv kev ua tau zoo ntawm peb hom tshuaj sealant thib ob rau cov iav rwb thaiv tsev
Qhov zoo ntawm polysulfide sealant yog tias nws muaj cov pa dej tsawg thiab cov pa roj argon tsawg ntawm chav tsev kub; nws qhov tsis zoo yog tias nws muaj tus nqi nqus dej siab.
Qhov modulus thiab elastic rov qab los ntawm qhov kub nce ntxiv, thiab qhov dej vapor transmittance kuj loj heev thaum kub siab. Tsis tas li ntawd, vim nws tsis zoo UV laus, UV irradiation ntev yuav ua rau cov yas tsis lo.
Qhov zoo ntawm polyurethane sealant yog tias nws cov dej pa thiab argon roj transmittance tsawg, thiab cov dej pa transmittance kuj qis thaum kub siab; nws qhov tsis zoo yog tias nws tsis muaj UV laus tiv taus.
Cov roj hmab silicone yog hais txog cov roj hmab uas muaj polysiloxane ua cov khoom siv tseem ceeb, tseem hu ua cov roj hmab silicone uas ua los ntawm kev ua liaj ua teb. Cov saw polymer ntawm cov roj hmab silicone feem ntau yog tsim los ntawm Si-O-Si, uas sib txuas ua ke los ua ib lub network zoo li Si-O-Si pob txha thaum lub sijhawm kho. Lub zog Si-O bond (444KJ/mol) siab heev, tsis yog tsuas yog loj dua li lwm cov zog polymer bond xwb, tab sis kuj loj dua li lub zog ultraviolet (399KJ/mol). Cov qauv molecular ntawm cov roj hmab silicone ua rau cov roj hmab silicone muaj kev tiv taus kub thiab txias zoo heev, tiv taus huab cua thiab tiv taus UV laus, nrog rau kev nqus dej tsawg. Qhov tsis zoo ntawm cov roj hmab silicone thaum siv rau hauv cov iav rwb thaiv tsev yog cov pa roj nkag tau zoo.
3. Xaiv cov sealant thib ob rau cov iav rwb thaiv tsev kom raug
Yog tias qhov chaw sib txuas ntawm polysulfide kua nplaum, polyurethane kua nplaum thiab iav raug tshav ntuj ntev, yuav muaj kev tshem tawm cov kua nplaum, uas yuav ua rau daim iav rwb thaiv tsev sab nraud ntawm phab ntsa iav zais kom poob lossis kev sib khi ntawm iav rwb thaiv tsev ntawm phab ntsa iav txhawb nqa kom tsis ua haujlwm.Yog li ntawd, cov sealant thib ob rau cov iav rwb thaiv tsev ntawm cov ntaub thaiv phab ntsa zais thiab cov ntaub thaiv phab ntsa semi-zais yuav tsum siv cov sealant silicone, thiab qhov loj ntawm qhov interface yuav tsum tau xam raws li JGJ102 "Cov Lus Qhia Txog Kev Tsim Kho Phab Ntsa Iav";
Cov sealant thib ob rau cov iav rwb thaiv tsev ntawm cov iav thaiv phab ntsa uas txhawb nqa yuav tsum siv cov sealant silicone; rau cov sealant thib ob ntawm cov iav rwb thaiv tsev rau cov phab ntsa loj qhib, nws raug pom zoo kom siv cov sealant silicone rau cov iav rwb thaiv tsev.Cov tshuaj nplaum thib ob rau cov iav rwb thaiv tsev rau cov qhov rooj, qhov rai thiab cov phab ntsa qhib dav dav tuaj yeem yog cov tshuaj nplaum silicone rau cov iav rwb thaiv tsev, cov tshuaj nplaum polysulfide lossis cov tshuaj nplaum polyurethane.
Raws li cov saum toj no, cov neeg siv yuav tsum xaiv cov khoom siv foob thib ob uas tsim nyog rau cov iav rwb thaiv tsev raws li kev siv tshwj xeeb ntawm cov iav rwb thaiv tsev. Vim tias qhov zoo ntawm cov foob tau tsim nyog, tsuav yog xaiv thiab siv kom raug, cov iav rwb thaiv tsev tuaj yeem tsim tau nrog lub neej ua haujlwm uas ua tau raws li qhov yuav tsum tau siv. Tab sis yog tias xaiv thiab siv tsis raug, txawm tias cov foob zoo tshaj plaws kuj tseem tuaj yeem tsim cov iav rwb thaiv tsev uas tsis zoo.
Thaum xaiv cov sealant thib ob, tshwj xeeb tshaj yog cov silicone structural sealant, peb kuj yuav tsum xav txog tias cov silicone sealant yuav tsum ua tau raws li qhov yuav tsum tau ua haujlwm ntawm cov iav insulating, qhov sib xws nrog cov sealant butyl sealing thawj zaug, thiab kev ua haujlwm ntawm cov silicone sealant yuav tsum ua tau raws li cov qauv tsim nyog. Tib lub sijhawm, qhov ruaj khov zoo ntawm cov khoom silicone sealant, qhov nrov ntawm cov chaw tsim khoom silicone sealant, thiab cov peev xwm kev pabcuam thiab cov theem ntawm cov chaw tsim khoom hauv tag nrho cov txheej txheem ntawm kev muag khoom ua ntej, kev muag khoom, thiab tom qab muag khoom kuj yog cov yam tseem ceeb uas cov neeg siv yuav tsum xav txog.
Cov tshuaj nplaum iav rwb thaiv tsev yog ib feem me me ntawm tag nrho cov nqi tsim cov iav rwb thaiv tsev, tab sis nws muaj feem cuam tshuam loj heev rau qhov zoo thiab lub neej ua haujlwm ntawm cov iav rwb thaiv tsev. Cov tshuaj nplaum iav rwb thaiv tsev tseem muaj feem cuam tshuam ncaj qha rau cov teeb meem kev nyab xeeb ntawm phab ntsa. Tam sim no, vim tias kev sib tw hauv kev lag luam sealant nce ntxiv, qee lub tuam txhab tsim cov tshuaj nplaum tsis yig los txi cov khoom ua tau zoo thiab zoo thaum txo cov nqi kom yeej cov neeg siv khoom ntawm tus nqi qis. Muaj ntau cov khoom siv sealant iav rwb thaiv tsev zoo thiab tus nqi qis tau tshwm sim hauv kev ua lag luam. Yog tias tus neeg siv xaiv nws tsis saib xyuas, txhawm rau txuag me ntsis tus nqi ntawm cov tshuaj nplaum, nws yuav ua rau muaj kev phom sij rau kev nyab xeeb lossis txawm tias ua rau muaj kev sib tsoo zoo, uas yuav ua rau muaj kev poob loj.
Siway xav kom nej xaiv cov khoom zoo thiab cov khoom zoo; tib lub sijhawm, peb yuav qhia rau nej txog ntau yam kev phom sij uas tshwm sim los ntawm kev siv cov sealant iav tsis zoo thiab kev siv tsis raug rau yav tom ntej.
