Cov yam ntxwv ci vapor barrier daim kab xev

Gidroparoteploizolyatsionnaya ntawv ci daim kab xev adhered mus rau lub ntxuav thiab qhuav degreased nto. Cov khoom nws tus kheej yog nkag rau hauv thawv, qhov ntev yog 420x420x600 hli. Nws yuav tsum tsis txhob yuav ua rau ib kub hauv qab no + 10 ° C. Lub tapes muaj ib lub hauv paus polyethylene ua npuas ncauj uas yog laminated nrog ib sab metallised polypropylene zaj duab xis, thaum lub lwm yam muaj ib tug waterproof nplaum txheej uas saib kuas txhim khu kev qha fastening khoom rau pob zeb ua, cib, hlau, yas thiab ntoo lug.

Nws yog raws li nyob rau hauv ib cov ntaub ntawv uas muaj kaw cellular qauv, nws muaj tsawg hygroscopicity thiab tsis yog absorbs dej. Lub elasticity yog muab los ntawm polyethylene ua npuas ncauj, uas guarantees sealing ntawm lub nqaws uas ua degrees ntawm roughness. High txhua yam zog twb tiav vim lub xub ntiag ntawm polypropylene zaj duab xis uas yog resistant rau alkalis, acids thiab organic kuab tshuaj. Lub paab txheej yog kev tiv thaiv los ntawm cov neeg kho tshuab kev puas tsuaj thiab oxidation. Cov nplaum txheej yog dej ruaj khov lo uas yog generated nyob rau hauv lub hauv paus ntawm cov khoom cua roj hmab. Nws muaj enhanced adhesion zog ntaub ntawv sib txawv, enabling rau daim kab xev nto tsis muaj pretreatment.

rau cov ntaub ntawv

Koj muaj peev xwm tsis ntshai hais tias cov pa barrier sawb yog glued mus rau hauv ib yob, raws li muaj ib tug tiv thaiv txheej ntawm siliconized rau nws saum npoo. Siv xws parogidroteploizolyatsionnaya mounting daim kab xev rau pob qij txha, pob caus ntawd thiab kev sib txuas ntawm txawv Siv, nrog rau cov installation ntawm qhov rais thav ntawv, ntoo, hlau, yas thiab qhob.

ntaub ntawv ntev

Tus zaj duab xis thickness yog 20 microns thaum qhov ntev yog 15 m, thiab cov dav yuav thaj tsam li ntawm 90 mus 200 mm. Nyob rau hauv txoj cai 120, thiab 150 hli raws li lub intermediate qhov tseem ceeb.

kev yam ntxwv

Vapor barrier daim kab xev rau lub qhov rais muaj ib tug high thermal coefficient ntawm thiaj, uas mus txog 95%. Coefficient ntawm thermal conductivity yog heev me me, thiab nyob rau hauv 20 ° C nws yog nyob rau hauv ntau 0,038-0,051 W / m ° C. Coefficient ntawm tshav kub haum thaum lub sij hawm lub hnub nce mus txog ib tug 0.48 (W / m ² ° C). Thermal kuj yog sib npaug zos rau 0.031 ° C / W, uas yog siv tau rau ib tug millimeter thickness. Cov tub txawg tej zaum xav kuj yog xws li ib tug yam ntxwv raws li cov kev tshav kub muaj peev xwm. Nyob rau hauv rooj plaub piav los ntawm tus vapor barrier zaj duab xis , qhov no parameter yog 1,95 kJ / kg ° C.

Nyob rau hauv load nyob rau hauv ib tug ntau ntawm 2-5 kPa cia modulus yuav sib txawv ntawm 0,26 mus 0.6 MPa. Vapor barrier daim kab xev rau lub qhov rais thiab muaj lwm tseem ceeb kom zoo dua, uas yog qhia nyob rau hauv lub peev xwm los nqus nrov. Yog li, lub suab haum yog 32 dB. Khoom hais txog cov pab pawg neeg G2 flammability, haus luam yeeb-txoj kev muaj peev xwm - D3. Cov kev ceev ntawm cov ntaub ntawv uas tej zaum yuav sib npaug zos rau 50 thiab 80 kg / m ^3.

Nta installation ntawm lub sealing sawb

Vapor barrier daim kab xev rau lub qhov rais, yam ntxwv ntawm cov uas tau hais saum toj no, nws yuav tsum tau ntsia nyob rau hauv no cov ntaub ntawv uas tsim los rau algorithm. Rau hauv sealing leeg yog siv dubbed vapor barrier daim kab xev rau lub hauv paus ntawm txhuas ntawv ci. Rau txhim khu kev qha thiab yooj yim kho nyob saud yog nplaum bands uas yog situated rau ntawm ob sab. Rau daim kab xev yuav tsum tau ntsia ib ncig ntawm lub perimeter ntawm lub qhov rais, thiab ces kaw cia slopes, uas yog teem los ntawm qhuav txoj kev.

Yuav kom muab lub puab vapor barrier daim kab xev nyob rau hauv thawj theem yuav tsum tau txiav rau hauv ib tug neeg daim, qhov ntev uas yog ncaj rau tus dav thiab ntev ntawm lub qhov rais. Yuav kom cov no yuav tsum muab ntxiv tus nqi ntawm 10 cm, uas yuav mus rau ntawm lub ces kaum pob qij txha. Raws qhov ntev ntawm ribbon koom overlapping, lub dav ntawm uas yuav tsum tau kwv yees li 1/2 lub dav ntawm cov khoom.

Hauv vib this kev ntawm lub chaw ua hauj lwm

Vapor barrier daim kab xev rau PVC qhov rai uas nws daim ntawv thov yog piav nyob rau hauv kom meej nyob rau hauv ib tsab xov xwm nyob rau hauv lub tom ntej no theem yog tso los ntawm tus tiv thaiv daim ntawv sawb ntawm lub duplexed. Tam sim no cov ntaub ntawv uas muaj peev xwm yuav glued mus rau profile rau ntawm tus ncej. Qhov no yuav tsum tau ua nyob rau hauv nro, thiab lub puab ntug ntawm lub nplaum txheej yuav tsum tau los piv nrog rau lub puab ncej ntug. Cov kev tiv thaiv txheej uas yog nyob rau ib butyl roj hmab txheej yuav tsum tsis txhob muab tshem tawm nyob rau ntawm no theem.

Nyob rau hauv thiaj li yuav lo ib daim hlab ntawm adhesion twb tsis txo, nws yog tsim nyog los kom cov qauv nyob rau hauv lub qhib txoj hauj lwm tsawg lub sij hawm, thiab ua ntej ua ke rau qhov chaw ntawm lub qhov rais yuav tsum tau wiped nrog ib tug mos mos daim ntaub los yog daim ntawv phuam.

xaus
