Polyethylene Vapor Barrier
Product Description
Peb lub tuam txhab, Shanghai Yingfan Engineering Material Co., yog ib qho ntawm cov ua polyethylene dej vapor barrier manufacturers hauv Suav teb. Peb muab cov yas yas yas polyethylene vapor barrier nyob rau hauv pob zeb slab los yog tom qab cement board los yog rau hauv qab daus los yog hauv qab daus phab ntsa. 6mil / 9mil / 10mil / 20mil / lwm mil tuab polyethylene vapor barriers muaj nyob rau hauv peb cov khoom.

Polyethylene vapor barrier Taw qhia (cited los ntawm wiki)
Lub vapor barrier (los yog vapor barrier) yog ib yam khoom siv los ua pov thawj, feem ntau yog ib daim ntawv yas lossis ntawv ci, uas tiv thaiv kev ya raws ntawm phab ntsa, hauv pem teb, qab nthab, lossis lub ru tsev sib dhos ntawm cov tsev kom tiv thaiv kev sib txuam thiab ntim khoom. Technically, ntau ntawm cov ntaub ntawv no tsuas yog vapor retarders raws li lawv muaj ntau qib ntawm permeability.
Cov ntaub ntawv muaj tus nqi ya raws vapor kis tau tus nqi (MVTR) uas yog tsim los ntawm cov qauv kev sim. Ib pawg ntawm cov chav nyob yog g / m²·hnub lossis g / 100in²·hnub. Permeability tuaj yeem tshaj tawm hauv perms, kev ntsuas ntawm qhov hloov pauv ntawm cov dej vapor los ntawm cov khoom (1.0 US perm = 1.0 grain / square-foot·hour·inch ntawm mercury ≈ 57 SI perm = 57 ng / s·m2·Pa ). Asmeskas cov cai hauv tsev tau cais cov vapor retarders raws li muaj dej vapor permeance ntawm 1 perm lossis tsawg dua thaum kuaj raws li ASTM E96 desiccant, los yog cov khob khob qhuav.[1] Vapor-retarding cov ntaub ntawv feem ntau yog categorized li:
Impermeable (≤1 US perm, los yog ≤57 SI perm) - xws li asphalt-backed kraft ntawv, elastomeric txheej, vapor-retarding xim, roj-raws li xim, vinyl phab ntsa npog, extruded polystyrene, plywood, OSB;
Semi-permeable (1-10 US perm, los yog 57-570 SI perm) - xws li unfaced expanded polystyrene, fiber-faced isocyanurate, hnyav asphalt-impregnated tsev ntaub ntawv, ib co latex-raws li xim xim);
Permeable (> 10 US perm, los yog> 570 SI perm) - xws li unpainted gypsum board thiab plaster, unfaced fiber iav rwb thaiv tsev, cellulose rwb thaiv tsev, unpainted stucco, cement sheathings, spunbonded polyolefin los yog ib co polymer-raws li sab nrauv cua barrier films.
Polyethylene vapor barrier: High density polyethylene vapor barrier
Peb yog cov chaw tsim khoom lag luam paub zoo ntawm high density polyethylene dej vapor barrier hauv Suav teb. Peb cov khoom permeability qis dua ≤1.0 × 10-13 g•cm (cm2) •pa. Yog li nws tuaj yeem raug categorized li impermeable vapor barrier. Nws lub neej ntev tuaj yeem kav ntev dua 70 xyoo hauv daim ntawv thov no. Qhov dav tuaj yeem ncav cuag ntau dua 8m thiab qhov ntev tuaj yeem ncav cuag ntau dua 800m.

Damp proofing yog ib qho tseem ceeb heev ntawm kev ua kom lub tsev ruaj khov thaum tsim kev tsim kho. Peb cov cuab yeej hloov tau yooj yim thiab zoo impermeable ntawm peb cov polyethylene noo noo barrier tau raug pov thawj nyob rau hauv ntau vapor barrier tej yaam num rau pem teb thiab phab ntsa dua thiab dua.
Rau polyethylene vapor barrier nqe, koj tuaj yeem qhia peb qhov muag raws li peb cov cuab yeej sib tham hauv online lossis lwm yam kev sib cuag.
