Moisture Barrier Film

Dej Vapor Barrier Film / Moisture Barrier Film

Lub vapor barrier (los yog vapor barrier) yog txhua yam khoom siv rau cov tshuaj tsis haum, feem ntau yog ib daim ntawv yas los yog cov ntawv ci, uas tiv thaiv kev ya raws ntawm lub ntim kom tsis txhob muaj kab mob hauv cov khaub ncaws. Technically, ntau cov ntaub ntawv no tsuas yog vapor retarders raws li lawv muaj kev sib txawv ntawm permeability.

Cov ntaub ntawv siv rau hauv cov hnab ntim tau yoojyim muaj ib qho kev qhia txog tus kabmob vistor (kis MVTR). Cov ntaub ntawv xws li cov ntawv ci, LLDPE, thiab PVDC muaj cov khoom ya zoo heev ntawm kev sib zog. Peb yuav ua haujlwm nrog koj mus rau tus kws kho-neeg nruab siab ib lub khoom ntim tau yooj yim uas yuav tiv thaiv koj cov khoom siv los ntawm cov dej noo.

Cov ntaub ntawv muaj cov vigorous vapor kis tau tus nqi uas yog tsim los ntawm cov qauv kev xeem. Ib hom txheej txheem twg yog g / m² · hnub los sis g / 100in² · hnub. Permeability tuaj yeem raug tshaj tawm hauv cov perms, ib qho kev ntsuas ntawm cov dej xa mus los ntawm cov khoom siv (1.0 US perm = 1.0 grain / square-foot · hour · inch of mercury ≈ 57 SI perm = 57 ng / s · m2 · pa ).

Cov kev ua haujlwm ntawm cov dej khov tsis muaj dej khov yog ua kom cov neeg tawg rog ntawm cov dej ua tsis muaj dej, uas tsis yog ib txwm siv los tuav lub tsiv ntawm huab cua. Thaum cov huab cua sib xyaw nrog dej pa, nws txav ntawm qhov chaw mus rau qhov chaw vim muaj huab cua qhov sib txawv, lub pa taws tsiv nrog nws.

Lub peev xwm ntawm ib lub pob los tswj cov permeation thiab nkag mus ntawm gasses yog qhov tseem ceeb rau ntau hom khoom. Cov kev kuaj no feem ntau ua rau cov ntaub ntawv ntim khoom tab sis tseem nyob ntawm cov pob khoom ua tiav, tom qab raug rau kev khawb, tuav, vibration, lossis kub. Kev kuaj loj tshaj plaws, Kev kuaj pob, Kev sib ncawg mus kis tus kabmob (MVTR), Cov pa oxygen kis tus nqi (OTR) thiab Cov tshuaj carbon dioxide.

Barrier txheej ntaub ntawv:

Cov txheej txheem txheej txheej txheej txheem feem ntau kuj yog ib qho kev sib thooj, thiab nruab nrab teeb meem txheej tau qee zaum ntawm qhov hnyav. Vim hais tias nws yog lub compostion ntawm cov barrier cov khoom, thiab nws tsis yog cov tuab uas yog feem ntau ua hauj lwm hauv kev txiav txim siab nws permeability. Hlau ntawv ci, feem ntau cov ntawv ci txhuas feem ntau yog cov khoom siv vapor barrier, zoo li taug qab los ntawm cov kab los ua teeb meem. Lub tshuab nqus hlau hlau (nplaum txhuas), EVOH, barrier nylon (PVDC coated) yog pob tshab thaiv txheej txheej feem ntau siv hauv cov khoom noj khoom haus. Lub txheej thaiv txheej txhuas ntawm aluminium oxide (AlOx) zoo ib yam li hauv cov dej qab ntsev rau Teflon, thiab pom tias yog ib qho khoom muaj zog / cov pa oxygen tsis sib haum nrog cov ntawv ci laminates. Txhua yam khoom pov thaiv khoom thiab kev tsim tawm muaj nws tus kheej tsis muaj teeb meem. Ntawm no yog nyob rau hauv daim ntawv teev cov tsiaj ntawv Haide.

Xaiv txoj cai zaj duab xis:

Thaum txiav txim siab tias qhov yeeb yaj kiab tsis muaj tseeb yog qhov tseeb rau koj daim ntawv thov, cov hauv qab no yuav tsum raug xam tias:

● Koj xav kom muaj tus kabmob microclimate zoo li cas? Txij li thaum sib txawv ntawm cov pa thiab noo noo kis nws txawv los ntawm kev xaiv ntau zaj duab xis thiab lamination.

● Koj xav kom muaj lub sijhawm ntev li cas? Tsis muaj ib txoj hauv kev siv cov yeeb yaj kiab zoo tshaj plaws yog tias koj xav tau tsuas yog muaj chaw tswj tau ob peb lub lim piam, tiam sis ntev cia yuav tsum muaj kev thaj yeeb zoo dua vim tias qhov kis tau tus kab mob vapor txawv nws txawv los ntawm cov yeeb yam sib txawv.

● Koj puas tau sau nitrogen lossis nqus cov hnab ntim khoom? Koj yuav tswj cov microclimate li cas? Ib qho kev ua ub no yog kev zam txim ntau tshaj ib qho raws li cov neeg ua pa dhau los.

● Koj puas xav tau kev kuaj xyuas ntawm cov khoom uas muaj xws li lub qhov rai ntawm cov hnab? Yuav ua li cas theem barrier zaj duab xis yuav zoo los yog ntawv ci raws li films yog opaque.

● Cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj los yog cov qauv nqi puas tseem ceeb? Txawm tias cov ntaub ntawv feem ntau yog qhov qis tshaj plaws ntawm ib qhov project, qhov txuag tau nyiaj yuav muaj nuj nqis rau ib qhov loj. Peb mam li pab koj txiav txim siab txog cov qauv zoo tshaj plaws yuav tsum tau thov rau koj cov kev xav tau.
