Npaj thaiv kab xev, nrog rau txoj kab nqes tiav, tuaj yeem txhim kho cov yam ntxwv zoo ntawm cov qauv, uas ua rau nws lub neej ua haujlwm ntev. Ntawm kev muag khoom koj tuaj yeem pom cov kab xev uas muaj cov nplaum nplaum ntawm ib lossis ob sab. Nws yog tsim los kho cov kab xev rau lub qhov rais thiab phab ntsa. Ntawm lwm yam, cov ntaub ntawv no raug cais raws li qhov kub thiab txias thaum lub sijhawm ua haujlwm.
Thawj ntau yam tsim nyog rau lub caij ntuj sov thiab tuaj yeem siv tau ntawm qhov kub ntawm +5 txog +35 ° C, thaum cov khoom tsim los rau lub caij ntuj no tuaj yeem tiv taus kub hauv qab xoom degrees. Qhov dav ntawm xws li ib lub strip tuaj yeem sib txawv nyob ntawm cov dej num, uas tso cai rau nws muab vapor barrier rau cov pob qij txha ntawm ntau qhov sib txawv. Thaum xaiv ib daim kab xev vapor barrier, koj yuav tsum xav txog tias nws qhov dav yuav tsum yog 45 hli ntau tshaj qhov kev teeb tsa.
Kev piav qhia dav dav
Cov kab xev piav qhia rau kev teeb tsa sab nraum zoov tuaj yeem ua los ntawm cov ntaub ntawv ua npuas dej, lawvxav tau rau kev sib khi cov pob qij txha thiab tuaj yeem siv ua ke nrog plaster mortar, uas ua rau cov yam ntxwv ntawm vapor barrier. Muaj vapor barrier daim kab xev rau qhov rais ntawm kev muag khoom, cov yam ntxwv, cov duab uas tau nthuav tawm hauv tsab xov xwm. Lub hauv paus ntawm cov khoom siv no tuaj yeem yog roj hmab butyl, uas yog tsim los kaw cov pob qij txha thiab nruab rau ntawm qhov rais thiab qhov rooj thaiv. Cov khoom muaj xws li cov ntaub ntawv uas tsis yog-woven, primed thaum lub sij hawm installation, them nrog plaster nyob rau theem tom ntej, thiab pleev xim rau nyob rau hauv lub kawg theem. Hom no muaj cov txheej txheem ntawm tus kheej. Yog tias koj xav tau daim kab xev vapor barrier uas yuav siv rau hauv cov av noo siab, tom qab ntawd koj yuav tsum tau nruab cov khoom nyob rau hauv qhov chaw qhuav ntawm qhov chaw, siv ntau yam metallized.
Ntawm cov ntawv ci vapor barrier daim kab xev
Ntawv nyiaj hydro-steam thiab tshav kub-insulating daim kab xev yog glued los ntxuav, qhuav, raws li zoo raws li yav tas los degreased nto. Cov khoom nws tus kheej yog nkag rau hauv lub thawv, qhov ntev ntawm 420x420x600 mm. Nws yuav tsum tsis txhob ua haujlwm ntawm qhov kub hauv qab +10 ° C. Cov ntaub nplaum yog ua los ntawm foamed polyethylene, uas yog laminated thiab metallized nrog polypropylene zaj duab xis ntawm ib sab, thaum nyob rau sab nraud muaj cov nplaum nplaum uas muaj kev ruaj ntseg ruaj ntseg cov khoom rau pob zeb, cib, hlau, yas thiab ntoo.
Raws li cov khoom siv uas muaj cov qauv kaw ntawm tes, nws muaj hygroscopicity tsawg thiab yuav luagtsis nqus dej noo. Elasticity yog guaranteed ua tsaug rau polyethylene ua npuas ncauj, uas guarantees lub sealing ntawm cov pob qij txha nrog txawv degrees ntawm unevenness. Lub zog txhua yam tau ua tiav vim muaj cov yeeb yaj kiab polypropylene, uas tiv taus alkalis, organic solvents thiab acids. Cov txheej txheej muaj kev tiv thaiv los ntawm kev puas tsuaj thiab oxidation. Cov nplaum txheej muaj cov dej-resistant nplaum, uas yog tsim los ntawm cov roj hmab hluavtaws. Nws tau txhim kho adhesion rau cov khoom sib txawv, uas tso cai rau cov ntaub nplaum siv yam tsis tau npaj ua ntej.
rau kev siv
Koj tsis tuaj yeem ntshai tias daim kab xev vapor barrier yuav lo ua ke hauv ib yob, vim muaj cov txheej txheem siliconized ntawm nws qhov chaw. Xws li cov chav dej-hydrothermal insulating mounting daim kab xev yog siv rau seams, knots thiab pob qij txha ntawm ntau yam tsev, nrog rau thaum txhim kho qhov rais blocks, ntoo khoom, hlau, yas thiab pob zeb.
Khoom loj
Lub thickness ntawm zaj duab xis yog 20 microns, thaum qhov ntev yog 15 m, thiab qhov dav yuav txawv ntawm 90 mus rau 200 hli. 120 thiab 150 mm yog siv los ua tus nqi nruab nrab.
Specifications
Npaj thaiv daim kab xev rau lub qhov rais muaj cov coefficient siab ntawm thermal reflection, uas ncav cuag 95%. Lub coefficient ntawm thermal conductivity yog tsawg heev, thiab nyob rau ntawm 20 ° C nws yog nyob rau hauv thaj tsam ntawm 0.038-0.051 W / m ° C. Thaum tshav kub kub nqus coefficient thaum nruab hnubnce mus txog 0.48 W / (m2 °C). Lub thermal tsis kam yog 0.031 ° C / W, uas yog qhov tseeb rau ib millimeter tuab. Cov kws tshaj lij qee zaum kuj xav paub txog tus yam ntxwv zoo li lub peev xwm tshwj xeeb. Nyob rau hauv cov ntaub ntawv ntawm cov piav qhia vapor barrier zaj duab xis, qhov parameter no yog 1.95 kJ / kg ° C.
Thaum thauj khoom hauv 2-5 kPa, lub zog hloov pauv ntawm elasticity tuaj yeem sib txawv ntawm 0.26 txog 0.6 MPa. Vapor barrier daim kab xev rau lub qhov rais muaj lwm qhov zoo dua, uas yog qhia nyob rau hauv lub peev xwm nqus cov suab nrov extraneous. Yog li, lub suab nqus yog 32 dB. Cov ntaub ntawv belongs rau combustibility pawg G2, haus luam yeeb-tsim peev xwm - D3. Qhov ceev ntawm cov khoom tuaj yeem sib npaug li 50 thiab 80 kg / m 3.
Txhim kho daim kab xev sealing
Vapour barrier daim kab xev rau lub qhov rais, cov yam ntxwv ntawm cov uas tau hais los saum toj no, yuav tsum tau ntsia raws li lub algorithm tsim rau cov khoom no. Rau sab hauv sealing ntawm lub seam, ib daim kab xev duplicated vapor barrier daim kab xev raws li txhuas ntawv ci yog siv. Rau kev txhim khu kev qha thiab kho tau yooj yim, nws muaj cov nplaum nplaum, uas nyob ntawm ob sab. Daim kab xev yuav tsum tau muab ntsia ib ncig ntawm tag nrho ib puag ncig ntawm lub qhov rais, thiab tom qab ntawd kaw nrog cov nqes hav uas tau nruab rau hauv txoj kev qhuav.
Txhawm rau nruab daim kab xev sab hauv vapor barrier daim kab xev, thawj theem nws yuav tsum tau txiav rau hauv nyias daim nyias nyias, qhov ntev ntawm qhov yuav sib npaug ntawm qhov dav thiabqhov rai ntev. Rau cov nqi no yuav tsum tau ntxiv 10 cm txhua, uas yuav mus rau lub ces kaum pob qij txha. Qhov ntev ntawm daim kab xev yog sib tshooj, qhov dav ntawm qhov yuav tsum yog kwv yees li 1/2 qhov dav ntawm cov khoom.
Txoj kev ua haujlwm
Vapor barrier daim kab xev rau PVC qhov rais, kev siv uas tau piav qhia nyob rau hauv tsab xov xwm, yog tso tawm los ntawm cov ntaub ntawv tiv thaiv los ntawm sab ntawm lub duplicated sawb nyob rau theem tom ntej. Cov khoom siv tam sim no tuaj yeem txuas rau lub thav duab profile. Qhov no yuav tsum tau ua nyob rau hauv ib tug taut lub xeev, thiab lub puab ntug ntawm cov nplaum txheej yuav tsum coincide nrog lub puab ntug ntawm tus ncej. Cov txheej tiv thaiv uas nyob rau ntawm butyl roj hmab txheej yuav tsum tsis txhob muab tshem tawm nyob rau theem no.
txhawm rau txhawm rau qhov adhesion ntawm cov nplaum nplaum kom tsis txhob txo qis, koj yuav tsum ua kom cov qauv qhib rau lub sijhawm luv, thiab ua ntej gluing lub qhov rais saum npoo, koj yuav tsum tau so nrog cov ntaub mos muag lossis Paper phuam.
Zaj lus
Npaj thaiv kab xev rau lub qhov rais, qhov ntom ntawm uas tau hais los saum toj no, yuav tsum tau muab tso rau hauv ib daim, yuav tsum tsis muaj qhov khoob ntawm qhov chaw. Thaum kawg, koj yuav tsum tau nruab daim kab xev rau ntawm windowsill, thiab tom qab ntawd sib sau lub qhov rais nrog sashes.
