Polyethylene Vapor Pa puipui
Fa'amatalaga o oloa
O la matou kamupani, Shanghai Yingfan Engineering Material Co., o se tasi o taʻutaʻua polyethylene vai e gaosia pa puipui i Saina.Matou te tuʻuina atu le paʻu paʻu palasitika polyethylene taupou i lalo o sima poʻo tua o laupapa sima poʻo mo puipui pito i lalo poʻo lalo ifo.6mil/9mil/10mil/20mil/isi mil mafiafia polyethylene vapor pa puipui o loo maua i la matou sapalai.

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'aalo, 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 faʻaogaina i paʻu, o se fua 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 vai e 1 pe itiiti ifo pe a fa'ata'ita'iina 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'i fa'afefeteina, fa'amama cellulose, stucco e le'i valiina, sima sima, spunbonded polyolefin po'o nisi polymer-fa'avae i fafo ata puipui o le 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.
