ʻO Polyethylene Vapor Parrier
Hōʻike huahana
ʻO kā mākou hui, ʻo Shanghai Yingfan Engineering Material Co., ʻo ia kekahi o nā mea hoʻolaha nui o ka wai polyethylene wai ma Kina.Hāʻawi mākou i ka pale mahu polyethylene plastic puʻupaʻa ma lalo o ka pā paʻa a ma hope o ka papa sima a i ʻole no nā paia o lalo a lalo paha.6mil / 9mil / 10mil / 20mil / ʻē aʻe mil mānoanoa polyethylene vapor pale i loaʻa i loko o kā mākou lako.

Polyethylene vapor barrier Introduction (kui ʻia mai wiki)
ʻO ka pale mahu (a i ʻole ka vapor barrier) kekahi mea i hoʻohana ʻia no ka hōʻoiaʻiʻo ʻana, maʻamau he plastik a i ʻole pepa pepa, e kūʻē i ka hoʻoheheʻe ʻana o ka makū ma o ka pā, papahele, kaupaku, a i ʻole nā hui hale o nā hale e pale ai i ka condensation interstitial a me ka hoʻopili.ʻO ka ʻenehana, ʻo ka hapa nui o kēia mau mea he mea hoʻopaneʻe mahu wale nō no ka mea he ʻokoʻa nā pae o ka permeability.
Loaʻa i nā mea waiwai kahi moisture vapor transmission rate (MVTR) i hoʻokumu ʻia e nā ʻano hoʻokolohua maʻamau.Hoʻokahi pūʻulu maʻamau o ka g/m²·lā a i ʻole g/100in²·lā.Hiki ke hōʻike ʻia ka permeability i nā perms, kahi ana o ka neʻe ʻana o ka mahu wai ma o kahi mea (1.0 US perm = 1.0 grain/square-foot·hour·inch of mercury ≈ 57 SI perm = 57 ng/s·m2·Pa ).Ua hoʻokaʻawale ʻia nā code hale hale ʻAmelika i nā mea hoʻomaha mahu he 1 perm a i ʻole ka liʻiliʻi o ka mahu wai ke hoʻāʻo ʻia e like me ka ASTM E96 desiccant, a i ʻole ke ʻano kīʻaha maloʻo.[1]Hoʻokaʻawale ʻia nā mea hoʻopaʻa i ka mahu e like me:
Impermeable (≤1 US perm, a i ʻole ≤57 SI perm) - e like me ka asphalt-backed kraft paper, elastomeric coating, vapor-retarding paint, oil-based paints, vinyl wall covers, extruded polystyrene, plywood, OSB;
Semi-permeable (1-10 US perm, a i ʻole 57-570 SI perm) - e like me ka polystyrene i hoʻonui ʻole ʻia, ka fiber-faced isocyanurate, nā pepa hale kūkulu asphalt-impregnated kaumaha, kekahi mau pena i hoʻokumu ʻia i ka latex);
Permeable (>10 US perm, a i ʻole > 570 SI perm) – e like me ka papa gypsum i pena ʻole ʻia a me ka pāpaʻi, ke aniani fiber aniani i ʻike ʻole ʻia, ka pale cellulose, ka stucco i pena ʻole ʻia, nā sheathings sima, spunbonded polyolefin a i ʻole kekahi mau kiʻiʻoniʻoni pale ea ma waho.
Palena mahu polyethylene: Pale mahu polyethylene kiʻekiʻe
He mea hana kaulana mākou o ka polyethylene water vapor barrier ma Kina.ʻOi aku ka haʻahaʻa o kā mākou huahana ma mua o ≤1.0×10-13 g•cm(cm2)•pa.No laila hiki ke hoʻokaʻawale ʻia e like me ka impermeable vapor barrier.Hiki ke lōʻihi kona ola ma mua o 70 mau makahiki ma kēia noi.Hiki i ka laulā ke piʻi aku ma mua o 8m a hiki i ka lōʻihi ke piʻi ma mua o 800m.

pale mahu polyethylene kiʻekiʻe
pale mahu ma hope o ka papa sima
pale mahu polyethylene ma lalo o ka paʻi paʻa
He ʻāpana koʻikoʻi ka hoʻopaʻa ʻana i ka hale i ka wā e hoʻolālā ai i ke kūkulu ʻana.Ua hōʻoia ʻia kā mākou waiwai impermeable a me ka maikaʻi o kā mākou polyethylene moisture pale i ka nui o nā papahana pale mahu no ka papahele a me nā paia.
No ka polyethylene vapor barrier price, hiki iā ʻoe ke aʻo i kā mākou kūʻai aku e like me kā mākou mea hana kamaʻilio pūnaewele a i ʻole pili ʻē aʻe.
