Cov khoom siv vapor barrier feem ntau yog siv hauv chav damp thiab sov. Qhov no siv tau rau hauv qab daus thiab da dej.
Yuav tsum siv
Cov ntaub ntawv no yog siv rau hauv cov chav uas nyob hauv qab hauv av, nrog rau cov uas tshwj xeeb tshaj yog raug rau dampness. Nyob rau hauv xws li cov chav muaj ib tug ntau tsim ntawm chav, uas yog sov huab cua nrog dej hais. Rau cov xwm txheej zoo li no, txoj hauv kev rau kev tawm ntawm noo noo los ntawm chav tsev yog tsim nyog. Cov kev no dhau los ua lub qab nthab thiab phab ntsa. Vaporization yog ib qho txheej txheem uas muaj kev cuam tshuam rau lub tsev thiab cov khoom siv. Nws qhov cuam tshuam ua rau kev puas tsuaj ntawm cov qauv. Txhawm rau tiv thaiv cov xwm txheej zoo li no, txheej txheej vapor barrier raug teeb tsa, uas tuaj yeem siv ntau yam khoom siv.
Khoom siv rau vapor barrier
Vapour barrier khoom yuav tsum tsis muaj qhov zoo ntawm vapor barrier. Niaj hnub nimno membrane-hom ntaub ntawv muaj peev xwm ntawmmuab qee qhov cua ntws. Qhov no guarantees qhov tsis muaj lub thiaj li hu ua tsev cog khoom nyhuv. Cov dej noo ntau dhau yog khaws cia los ntawm cov khoom siv no, thaum huab cua tawm los ntawm nws tsis tuaj yeem ua rau cov khoom siv phab ntsa puas lawm.
Ntau yam ntawm cov khoom siv vapor barrier thiab tshuaj xyuas txog lawv
Yog tias koj txiav txim siab xaiv cov khoom siv vapor barrier, ces koj yuav tsum siv cov neeg siv khoom tshuaj xyuas. Feem ntau niaj hnub no lawv xaiv cov khoom siv rau qhov no, uas yog polyethylene. Thaum txhim kho nws, yuav tsum tau saib xyuas, vim muaj zog nro tuaj yeem ua rau cov yeeb yaj kiab puas. Nrog rau nws qhov nro ntawm cov yeeb yaj kiab, thaum cov khoom raug cuam tshuam los ntawm qhov kub thiab txias thaum lub caij hloov, qhov kev pheej hmoo ntawm kev puas tsuaj rau cov yeeb yaj kiab nce ntau. Tab sis qhov no tsis yog qhov teeb meem ntawm cov khoom siv xwb.
Raws li cov kws ua haujlwm hauv tsev, yog tias tsis siv cov polyethylene, nws yuav tsis cia hauv chav lossis cua. Qhov no txhais tau hais tias nws yuav tsis yooj yim sua kom tsim ib qho chaw zoo microclimate siv cov khoom siv zoo li no. Tias yog vim li cas nws tsis yog siv rau vapor barrier. Qee cov neeg siv khoom, xaiv cov khoom siv vapor barrier, yuav ib zaj duab xis yas, uas lawv mam li sim perforate ntawm lawv tus kheej. Lawv ua qhov no nrog kev pab los ntawm ib tug menyuam, nyob rau hauv uas cov ntsia hlau los yog lwm yam ntse ntsiab yog thawj tsav nyob rau hauv. Xws li kev hloov kho tshiab ntawm polyethylene yuav tsis tuaj yeem muab cov vapor barrier ntawm cov cua sov-insulating system thiab cov tsev tsim. Membrane cov ntaub ntawv muaj zoo sib xwsnrog polyethylene zaj duab xis zoo, tab sis radically txawv multilayer qauv.
Mastics
Thaum vapor barrier cov ntaub ntawv raug xaiv rau cov phab ntsa, qee cov neeg ua haujlwm hauv tsev yuav cov mastics tshwj xeeb tsim rau lub hom phiaj no. Yog tias koj siv cov sib tov zoo sib xws rau saum npoo ntawm lub qab nthab lossis phab ntsa, ces nws yuav dhau los ntawm huab cua los ntawm nws tus kheej thiab khaws cov dej noo. Xws li cov khoom sib tov yog siv rau kev kho deg kom txog rau thaum tso lossis kev teeb tsa ntawm cov txheej zoo nkauj tiav.
Membrane films thiab cov kws tshaj lij tswv yim
Vapor barrier cov ntaub ntawv rau vov tsev yog muag. Membrane films tuaj yeem paub qhov txawv ntawm lawv. Cov ntaub ntawv zoo li no yog siv los ua vapor-permeable vov tsev waterproofing. Ntxiv rau nws cov haujlwm tseem ceeb, raws li cov kws tshaj lij, xws li vapor barrier muaj peev xwm ua kom sov chav. Nws zoo kawg nkaus tiv thaiv los ntawm daus, nag, plua plav thiab soot. Siv nws yog tias tsim nyog los tiv thaiv cov qauv los ntawm cov teebmeem ntawm cua. Cov kws tshaj lij pom zoo tias nws yog cov khoom siv nrog vapor permeability zoo heev.
Membranes tuaj yeem raug hu ua cov khoom siv thoob ntiaj teb, qhov no qhia tau tias lawv tuaj yeem siv nrog cov ntaub ntawv rwb thaiv tsev. Feem ntau, xws li hydro-, vapor barrier cov ntaub ntawv muaj peb txheej. Txhua tus ntawm lawv muab lub zog, insulating zoo thiab tiv thaiv los ntawm kev cuam tshuam tsis zoo. Txhawm rau nteg ib txheej ntawm xws li daim nyias nyias, ntawm cov lus qhia ntawm cov neeg ua haujlwm paub txog, koj tuaj yeem ua tauncaj qha rau ntawm thermal rwb thaiv tsev los yog lwm lub hauv paus uas npog cov qauv kev txhawb nqa ntawm lub ru tsev. Xws li cov txheej membrane yog ntau yam, txij li, yog tias tsim nyog, nws tuaj yeem siv rau kev rwb thaiv tsev sab nraud ntawm cov phab ntsa ntsug ntawm lub tsev rau txhua lub hom phiaj.
Ntau yam ntawm yob vapor barrier
Yog tias koj xaiv cov khoom siv vapor barrier, lawv tus nqi yuav tsum txaus siab rau koj. Nws yuav nyob ntawm ntau yam thiab cov chaw tsim khoom. Yog hais tias peb tham txog glassine, uas yav tas los siv los ua vapor barrier, ces nws tus nqi yog 100 rubles ib 1 yob. Tam sim no, cov kws tsim khoom thiab cov kws ua haujlwm ntiag tug siv tsis yog nws xwb, tab sis kuj tseem muaj cov khoom siv niaj hnub no. Ntawm lawv, ib leeg-txheej zaj duab xis tuaj yeem paub qhov txawv, raws li qhov ntom ntom polyethylene. Cov khoom no muaj cov qauv xoob xoob thiab muaj qhov tsis xws luag.
Cov yeeb yaj kiab polyethylene tseem tuaj yeem sib txawv, uas kuj tau muab rau hauv cov yob nrog lub thickness ntawm 50 microns. Lub hnab ntim khoom siv niaj hnub no hauv kev tsim kho lub ru tsev txias, txawm tias lawv tsis muaj qhov zoo li vapor barrier zoo.
Tseem muaj cov khoom sib xyaw ua ke ntawm kev muag khoom, vapor permeability ntawm 15 mus rau 25 grams ib square meter ib hnub twg. Cov khoom siv no tsuas yog siv rau kev teeb tsa lub ru tsev txias, vim nws tsis muaj qhov tsim nyog vapor barrier zog. Yog tias koj txaus siab rau cov ntaub ntawv vapor barrier rau lub qab nthab ntawm da dej, ces koj tuaj yeem xaiv aluminium lossis lwm yamhlau ntawv. Lub vapor permeability ntawm cov khoom no yog xoom, uas yog vim li cas nws yog siv los ua kom tiav chav chav.
Zaj lus
Hauv cov khw muag khoom siv niaj hnub no koj tuaj yeem pom cov ntaub ntawv vapor barrier hauv ntau hom, ntawm lawv muaj cov ntawv ci uas muaj cov qauv ua ke. Raws li cov builders, lawv yuav tsum tau siv nyob rau hauv cov chav uas nws tej yam kev mob yog yus muaj los ntawm ib tug high humidity thiab kub tej yam kev mob. Qhov no siv rau cov pas dej da dej, saunas thiab da dej. Cov neeg siv khoom kuj teb tau zoo rau cov duab los qhia, uas yog laminated ntawm ib sab nrog polyethylene. Nws yog siv rau vapor barrier ntawm chav nyob rau hauv uas cyclic cua sov txuas nrog. Lub vapor permeability Performance index ntawm cov duab los qhia yog sib npaug rau qhov txwv ntawm 3 mus rau 5 grams ib square meter ib hnub twg.
