Kev xaiv thib ob sealant rau insulating iav

Lub iav txuag hluav taws xob rau cov tsev xws li cov tsev nyob, uas muaj cov thermal rwb thaiv tsev zoo thiab lub suab rwb thaiv tsev, thiab zoo nkauj thiab siv tau. Sealant rau insulating iav tsis suav rau qhov feem ntau ntawm cov nqi ntawm cov iav insulating, tab sis nws yog ib qho tseem ceeb heev rau kev ua haujlwm ntev thiab kev nyab xeeb ntawm insulating iav, yog li yuav xaiv nws li cas?

Hais txog insulating iav

Insulating iav yog ua los ntawm ob (los yog ntau tshaj) daim iav thiab spacers sib koom ua ke. Lub sealing hom feem ntau yog siv cov txheej txheem kua nplaum thiab cov kua nplaum sib koom ua ke. Tam sim no, ob lub foob nyob rau hauv cov kua nplaum sib txuas sealing qauv feem ntau yog siv. Cov qauv yog raws li qhia nyob rau hauv daim duab: ob daim iav yog sib cais los ntawm spacers, lub spacer thiab lub iav yog kaw nrog butyl kua nplaum nyob rau hauv pem hauv ntej, thiab sab hauv ntawm lub spacer yog sau nrog molecular sieve, thiab lub iav ntug thiab lub sab nraud ntawm lub spacer yog tsim. Qhov sib txawv yog kaw nrog ib tug thib ob sealant.

Hom thib ob sealants rau insulating iav

Muaj peb yam tseem ceeb ntawm insulating iav thib ob sealants: silicone, polyurethane thiab polysulfide. Txawm li cas los xij, vim yog polysulfide, polyurethane nplaum muaj qhov tsis zoo ntawm UV aging, thiab yog tias qhov chaw sib txuas nrog iav raug tshav ntuj ntev, degumming yuav tshwm sim. Yog tias qhov tshwm sim tshwm sim, cov ntawv txheej txheej ntawm cov iav insulating ntawm lub zais thav duab iav kab hlau rhuav phab ntsa yuav poob los yog kev sib khi ntawm cov iav insulating ntawm qhov taw tes-txhawb iav ntaub thaiv phab ntsa yuav ua tsis tiav. Cov qauv molecular ntawm silicone sealant ua rau silicone sealant muaj qhov zoo ntawm qhov zoo ntawm qhov kub thiab txias tsis kam, huab cua tsis kam thiab ultraviolet aging kuj, thiab tib lub sijhawm, cov dej nqus dej tsawg, yog li silicone feem ntau siv hauv khw. .

Kev phom sij ntawm kev siv tsis raug

Cov teeb meem tshwm sim los ntawm kev xaiv tsis raug ntawm cov sealant thib ob tuaj yeem muab faib ua ob pawg hauv qab no: ib qho yog qhov poob ntawm kev siv ntawm cov iav insulating, uas yog, qhov tseem ceeb ntawm cov iav insulating yog ploj; lwm qhov yog cuam tshuam txog kev nyab xeeb ntawm daim ntawv thov ntawm cov iav insulating - - Qhov ntawd yog, kev nyab xeeb kev nyab xeeb tshwm sim los ntawm kev poob ntawm cov iav insulating sab nrauv.

Cov laj thawj rau qhov tsis ua haujlwm ntawm insulating iav seals feem ntau yog:

Nyob rau hauv kev txheeb xyuas ntawm cov ntaub thaiv phab ntsa tsis zoo, nws pom los ntawm kev tsom xam tias muaj peb lub laj thawj tseem ceeb rau kev poob ntawm cov iav sab nrauv:

1.The compatibility ntawm insulating iav thib ob sealant;

2.Txawm li cas los xij, kom txuag tau tus nqi, cov neeg koom nrog dig muag nrhiav tus nqi qis, thiab cov sealant thib ob rau cov iav insulating siv cov khoom siv uas tsis yog-silicone sealants xws li polysulfide thiab silicone siv sealants;

3.Qee tus neeg ua haujlwm tsim kho tsis zoo thiab tsis nruj, ua rau muaj teeb meem ntawm kev txhaj tshuaj dav ntawm insulating iav thib ob sealant.

Kev ceev faj rau kev xaiv cov sealant thib ob

Qhov thib ob sealant rau insulating iav muaj kev cuam tshuam zoo thiab kev pab cuam lub neej ntawm insulating iav. Cov txheej txheem sealant rau insulating iav yog txawm ncaj qha ntsig txog kev nyab xeeb ntawm cov ntaub thaiv phab ntsa. Yog li ntawd, peb yuav tsum tsis tsuas yog xaiv cov khoom tsim nyog, tab sis kuj xaiv cov khoom tsim nyog.

Ua ntej, nws yog cov qauv-ua raws thiab raws li qhov xav tau. Qhov thib ob, tsis txhob siv cov roj uas txhaws taus. Thaum kawg, xaiv lub npe nrov xws li junbond
