Polyethylene vapor barrier Folasaga (sii mai le wiki)

O le pupuni ausa (po'o le pupuni ausa) o so'o se mea e fa'aaogaina mo le susū susu, e masani lava o se palasitika po'o se pepa pepa, e tete'e ai le fa'asalalauina o le susu i totonu o le puipui, fola, fa'aluga, po'o le taualuga o fa'apotopotoga o fale e puipuia ai le fa'asao fa'atasi ma le afifiina. I tulaga fa'atekinisi, o le tele o nei mea e na'o le fa'afefe o le ausa ona e eseese tikeri o le fa'aogaina.

O meafaitino e iai le fua faatatau o le susū o le ausa (MVTR) e fa'avaeina i metotia masani o su'ega. O le tasi seti masani o iunite o le g/m²·aso po'o le g/100in²·aso. E mafai ona lipotia le paʻu i paʻu, o se fuataga o le faʻafefe o le ausa vai e ala i se mea (1.0 US perm = 1.0 grain/square-futu·itula·inisi o mercury ≈ 57 SI perm = 57 ng/s·m2·Pa ). O tulafono faufale a Amerika ua fa'avasegaina fa'agata ausa o lo'o i ai le pa'u o le ausa vai e 1 pe itiiti ifo pe a fa'ata'ita'i e tusa ai ma le ASTM E96 desiccant, po'o le ipu fa'amago.[1] E masani ona fa'avasegaina mea e fa'aitiitia ai le ausa e pei o:

E le mafaia (≤1 US perm, poʻo le ≤57 SI perm) - e pei o pepa kraft faʻapipiʻi asphalt, elastomeric coating, vali faʻafefe ausa, vali faʻavae suauu, vinyl puipui puipui, polystyrene extruded, plywood, OSB;

Semi-permeable (1-10 US perm, poʻo le 57-570 SI perm) - e pei o le polystyrene faʻalauteleina e leʻi faʻaalia, fiber-faced isocyanurate, pepa faufale mamafa e faʻafefeteina, nisi o vali faʻavae;

Pa'u (>10 US perm, po'o le >570 SI perm) - e pei o le laupapa gypsum e le'i valiina ma le fa'ama'i, fa'alava tioata e le fa'afefeteina, fa'avela o le cellulose, fa'amau e le'i valiina, sima sima, spunbonded polyolefin po'o nisi polymer-fa'avae i fafo ata pa puipui ea.

Pa puipui ausa polyethylene: Pa puipui ausa polyethylene maualuga maualuga

O matou o se taʻutaʻua taʻutaʻua o le maualuga polyethylene vai vavao pa puipui i Saina. O a matou oloa e mafai ona maua e maualalo ifo nai lo le ≤1.0 × 10-13 g•cm(cm2)•pa. O lea e mafai ona fa'avasegaina o le pa puipui ausa e le mafai ona fa'asalaina. O lona ola umi e mafai ona sili atu i le 70 tausaga i lenei talosaga. O le lautele e mafai ona oʻo atu i le 8m ma le umi e mafai ona sili atu i le 800m.
