Polyethylene kohu arai Whakataki (i whakahuahia mai i wiki)
Ko te arai kohu (he arai kohu ranei) he mea e whakamahia ana mo te whakamakuku makuku, te tikanga he kirihou, he pepa takai ranei, e atete ana i te makuku i roto i te pakitara, te papa, te tuanui, te tuanui ranei o nga huihuinga o nga whare hei aukati i te hauhautanga o waenga me te takai. Ma te hangarau, ko te nuinga o enei rauemi he aukati kohu noa na te mea he rereke nga nekehanga o te uruhanga.
Ko nga taonga he reiti tuku makuku kohu (MVTR) ka whakatauhia e nga tikanga whakamatautau paerewa. Ko tetahi huinga waeine noa he g/m²·ra, g/100in²·ra rānei. Ka taea te korero te uruhanga i roto i nga perms, he inenga o te tere o te whakawhiti i te kohu wai i roto i tetahi papanga (1.0 US perm = 1.0 witi/square-foot·haora·inihi mēkuri ≈ 57 SI perm = 57 ng/s·m2·Pa ). Kua whakarōpūhia e nga ture hanga whare o Amerika nga mea aukati kohu wai he 1 perm iti iho ranei ina whakamatauria ki te ASTM E96 desiccant, tikanga kapu maroke ranei.[1] Ko nga rauemi aukati ngohe ka whakarōpūhia hei:
Korekore (≤1 US perm, he ≤57 SI perm ranei) - penei i te pepa kraft kua tuara i te asphalt, te paninga elastomeric, te peita aukati-wai, te peita hinu, te uhi pakitara vinyl, te polystyrene extruded, plywood, OSB;
Semi-permeable (1-10 US perm, 57-570 SI perm ranei) - penei i te polystyrene whakawhanui kore kanohi, te muka-waa isocyanurate, nga pepa hanga whare kua werohia ki te asphalt, etahi peita i runga i te latex);
Permeable (>10 US perm, he> 570 SI perm ranei) - penei i te papa gypsum me te raima kaore i peitahia, te whakamaarama karaihe muka kore kanohi, te kirikiri cellulose, te stucco kaore i pania, te raima sima, te polyolefin spunbonded, etahi kiriata arai hau o waho ranei.
Arai kohu polyethylene: Arai kohu polyethylene kiato teitei
He kaihanga rongonui matou o te parenga kohu wai polyethylene teitei i Haina. He iti ake to maatau hua i te ≤1.0×10-13 g•cm(cm2)•pa. No reira ka taea te whakarōpūtia hei arai kohu koretake. Neke atu i te 70 tau te roa o tona oranga i roto i tenei tono. Ka taea e te whanui te neke atu i te 8m me te roa ka neke atu i te 800m.
