1. Txheej txheem cej luam ntawm insulating iav
cov
Insulated iav yog hom iav txuag hluav taws xob uas tau siv dav hauv cov tuam tsev ua lag luam, cov khw loj loj, cov tsev nyob hauv siab thiab lwm lub tsev.Nws muaj cov rwb thaiv tsev zoo heev thiab lub suab rwb thaiv tsev thiab zoo nkauj thiab siv tau.Insulated iav yog ua los ntawm ob (los yog ntau tshaj) daim iav sib txuas nrog spacers.Muaj ob hom kev sib khi tseem ceeb: txoj kev sawb thiab txoj kev sib khi ua ke.Tam sim no, ob lub foob nyob rau hauv cov kua nplaum sib txuas txoj kev yog cov feem ntau siv sealing qauv.Cov qauv yog raws li pom nyob rau hauv daim duab 1: ob daim iav yog sib cais los ntawm spacers, thiab butyl sealant yog siv los kaw lub spacer thiab iav nyob rau hauv pem hauv ntej.Sau rau sab hauv ntawm lub spacer nrog molecular sieve, thiab kaw qhov sib txawv ntawm lub ntug ntawm lub khob thiab sab nraud ntawm lub spacer nrog ib tug thib ob sealant.
cov
Lub luag haujlwm ntawm thawj sealant yog los tiv thaiv dej vapor lossis inert gas los ntawm kev nkag mus thiab tawm hauv cov kab noj hniav.Butyl sealant feem ntau yog siv vim tias cov dej vapor kis tau tus nqi thiab inert gas kis tus nqi ntawm butyl sealant tsawg heev.Txawm li cas los xij, butyl sealant nws tus kheej muaj qhov sib txuas tsis tshua muaj zog thiab tsis tshua muaj elasticity, yog li cov qauv tag nrho yuav tsum tau kho nrog lub sealant thib ob los txuas cov iav daim hlau thiab spacers ua ke.Thaum lub iav insulating yog nyob rau hauv load, ib txheej ntawm sealant muaj peev xwm tuav tau zoo sealing nyhuv.Nyob rau tib lub sijhawm, tag nrho cov qauv tsis cuam tshuam.

2. Hom kev sealants thib ob rau insulating iav
cov
Muaj peb yam tseem ceeb ntawm cov sealants rau cov iav insulating: polysulfide, polyurethane thiab silicone.Table 1 teev qee tus yam ntxwv ntawm peb hom sealants tom qab lawv kho tag nrho.
Table 1 Kev sib piv ntawm cov yam ntxwv ntawm kev ua tau zoo ntawm peb hom thib ob sealants rau insulating iav
Qhov zoo ntawm polysulfide sealant yog tias nws muaj dej vapor tsawg thiab argon gas kis ntawm chav tsev kub;nws qhov tsis zoo yog tias nws muaj qhov nqus dej siab.
Lub modulus thiab elastic rov qab tus nqi txo qis heev thaum kub nce, thiab cov dej vapor transmittance kuj loj heev thaum kub siab.Tsis tas li ntawd, vim nws tsis zoo UV aging kuj, ntev UV irradiation yuav ua rau tsis-stick degumming.
cov
Qhov kom zoo dua ntawm polyurethane sealant yog tias nws cov dej vapor thiab argon gas transmittance qis, thiab cov dej vapor transmittance kuj tseem qis thaum kub siab;nws qhov tsis zoo yog tias nws muaj qhov tsis zoo UV aging kuj.
cov
Silicone sealant yog hais txog lub sealant nrog polysiloxane ua cov khoom siv tseem ceeb, tseem hu ua kev ua liaj ua teb cov khoom siv silicone sealant.Cov saw hlau polymer ntawm silicone sealant feem ntau yog tsim los ntawm Si-O-Si, uas yog cross-linked los tsim ib lub network-zoo li Si-O-Si skeleton qauv thaum lub sijhawm kho.Si-O daim ntawv cog lus lub zog (444KJ / mol) yog qhov siab heev, tsis tsuas yog loj dua lwm cov khoom siv hluav taws xob polymer, tab sis kuj loj dua lub zog ultraviolet (399KJ / mol).Cov qauv molecular ntawm silicone sealant enables silicone sealant kom muaj qhov kub thiab txias tsis kam, huab cua tsis kam thiab UV aging kuj, nrog rau kev nqus dej tsawg.Qhov tsis zoo ntawm silicone sealant thaum siv hauv cov iav insulating yog cov roj permeability siab.
3. Kev xaiv raug ntawm cov khoom sib txuas rau cov iav insulating
cov
Yog tias qhov sib txuas ntawm cov kua nplaum polysulfide, cov kua nplaum polyurethane thiab iav raug tshav ntuj ntev, degumming yuav tshwm sim, uas yuav ua rau cov iav insulating sab nraud ntawm lub zais thav duab iav kab hlau rhuav phab ntsa kom poob los yog kev sib khi ntawm cov iav. insulating iav ntawm taw tes-txhawb iav kab hlau rhuav phab ntsa ua tsis tiav.Yog li ntawd, lub sealant thib ob rau insulating iav ntawm cov ntaub thaiv phab ntsa thiab semi-pob thav duab kab hlau rhuav phab ntsa yuav tsum siv silicone structural sealant, thiab lub interface loj yuav tsum tau xam raws li JGJ102 "Technical Specifications for Glass Curtain Wall Engineering";
Qhov thib ob sealant rau insulating iav ntawm taw tes-txhawb iav ntaub thaiv phab ntsa yuav tsum siv silicone structural sealant;rau qhov thib ob sealant ntawm insulating iav rau loj-loj qhib ncej kab hlau rhuav phab ntsa, nws yog pom zoo kom siv insulating iav silicone structural sealant.Qhov thib ob sealant rau insulated iav rau lub qhov rooj, qhov rais thiab zoo tib yam qhib-thav duab ntaub phab ntsa yuav insulated iav silicone sealant, polysulfide sealant los yog polyurethane sealant.
Raws li cov saum toj no, cov neeg siv yuav tsum xaiv cov khoom tsim nyog thib ob sealant rau insulating iav raws li daim ntawv thov tshwj xeeb ntawm cov iav insulating.Ntawm qhov chaw uas cov sealant zoo tsim nyog, tsuav yog nws tau xaiv thiab siv kom raug, cov iav insulating tuaj yeem tsim nrog lub neej kev pab cuam uas ua tau raws li qhov yuav tsum tau siv.Tab sis yog tias xaiv thiab siv tsis raug, txawm tias qhov zoo tshaj plaws sealant yuav tsim cov iav insulating ntawm qhov tsis zoo.
Thaum xaiv cov sealant thib ob, tshwj xeeb tshaj yog cov khoom siv silicone sealant, peb yuav tsum xav txog tias silicone sealant yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov iav insulating, kev sib raug zoo nrog cov thawj sealing butyl sealant, thiab kev ua haujlwm ntawm silicone sealant yuav tsum ua tau raws li qhov yuav tsum tau ua. ntawm cov qauv tsim nyog.Nyob rau tib lub sijhawm, kev ruaj ntseg zoo ntawm cov khoom siv silicone sealant, qhov nrov ntawm silicone sealant manufacturers, thiab cov chaw tsim khoom muaj peev xwm muab kev pabcuam thiab qib hauv tag nrho cov txheej txheem ntawm kev muag khoom ua ntej, kev muag khoom, thiab kev muag khoom tom qab muag kuj tseem yog yam tseem ceeb uas cov neeg siv xav tau. xav txog.
cov
Insulating iav sealant tso nyiaj rau ib feem tsawg ntawm tag nrho cov iav insulating raug nqi, tab sis nws muaj kev cuam tshuam zoo rau qhov zoo thiab kev pab cuam lub neej ntawm insulating iav.Insulating iav structural sealant tseem muaj feem cuam tshuam ncaj qha rau cov ntaub thaiv phab ntsa teeb meem kev nyab xeeb.Tam sim no, raws li kev sib tw hauv kev lag luam sealant ua rau muaj kev kub ntxhov, qee cov neeg tsim khoom sealant tsis yig los txi cov khoom ua tau zoo thiab zoo thaum txo cov nqi txhawm rau kom yeej cov neeg siv khoom ntawm tus nqi qis.Ntau tus naj npawb ntawm cov khoom tsis zoo thiab tus nqi qis insulating iav sealant khoom tau tshwm sim hauv khw.Yog hais tias tus neeg siv xaiv nws carelessly, thiaj li yuav txuag tau ib tug me ntsis nqi ntawm sealant, nws yuav ua rau muaj kev ruaj ntseg txaus ntshai los yog txawm ua rau tsis zoo xwm txheej, uas yuav ua rau hnyav poob.
cov
Siway ntawm no hais kom koj xaiv cov khoom tsim nyog thiab cov khoom zoo;Nyob rau tib lub sijhawm, peb yuav qhia koj txog ntau yam kev phom sij los ntawm kev siv cov iav insulating tsis zoo thib ob sealant thiab siv tsis raug rau yav tom ntej.
