Polyethylene Vapor Barrier
Mafotokozedwe Akatundu
Kampani yathu, Shanghai Yingfan Engineering Material Co., ndi imodzi mwazinthu zotsogola za polyethylene zotchinga madzi ku China. Timapereka chotchinga cha pulasitiki cha pulasitiki cha polyethylene pansi pa slab konkriti kapena kuseri kwa bolodi la simenti kapena m'chipinda chapansi kapena makoma apansi. 6mil/9mil/10mil/20mil/mipiringidzo ina ya nthunzi ya polyethylene ikupezeka m'magawo athu.

Chiyambi cha Polyethylene vapor Barrier (otchulidwa kuchokera ku wiki)
Chotchinga cha nthunzi (kapena chotchinga cha nthunzi) ndi chinthu chilichonse chomwe chimagwiritsidwa ntchito potsimikizira chinyontho, nthawi zambiri pulasitiki kapena pepala lojambulapo, chomwe chimakana kufalikira kwa chinyezi kudzera pakhoma, pansi, padenga, kapena padenga la nyumba kuti aletse kukhazikika kwapakati komanso kulongedza. Mwaukadaulo, zambiri mwazinthu izi zimangochepetsa mpweya chifukwa zimakhala ndi milingo yosiyana ya permeability.
Zida zili ndi chiwopsezo chotumizira mpweya (MVTR) chomwe chimakhazikitsidwa ndi njira zoyeserera. Gulu limodzi lodziwika bwino ndi g/m²·day kapena g/100in²·day. Permeability akhoza lipoti mu perms, muyeso wa mlingo wa kusamutsidwa kwa nthunzi wa madzi kudzera zakuthupi (1.0 US perm = 1.0 njere/square-foot·hour·inch of mercury ≈ 57 SI perm = 57 ng/s·m2 · Pa ). Malamulo omanga aku America adayikapo zoletsa mpweya kukhala ndi mpweya wa 1 perm kapena kuchepera pomwe zimayesedwa molingana ndi ASTM E96 desiccant, kapena njira ya kapu youma. Zida zochepetsera nthunzi nthawi zambiri zimagawidwa motere:
Zosasunthika (≤1 US perm, kapena ≤57 SI perm) - monga mapepala a kraft opangidwa ndi asphalt, zokutira za elastomeric, utoto woletsa nthunzi, utoto wopangidwa ndi mafuta, zophimba pakhoma la vinyl, polystyrene yotulutsidwa, plywood, OSB;
Semi-permeable (1-10 US perm, kapena 57-570 SI perm) - monga polystyrene yowonjezereka, isocyanurate ya fiber-faced, mapepala omangira olemera a asphalt-impregnated, ena utoto wopangidwa ndi latex);
Zokwanira (> 10 US perm, kapena> 570 SI perm) - monga gypsum board osapentidwa ndi pulasitala, kutchinjiriza kwa magalasi osayang'ana, kusungunula kwa cellulose, stucco wosapaka, masinthidwe a simenti, spunbonded polyolefin kapena mafilimu ena otchinga mpweya opangidwa ndi polima.
Chotchinga cha nthunzi cha polyethylene: Chotchinga cha nthunzi chachikulu cha polyethylene
Ndife opanga odziwika bwino otchinga mpweya wa polyethylene ku China. Kuthekera kwa mankhwala athu ndikotsika kuposa ≤1.0×10-13 g•cm(cm2)•pa. Chifukwa chake imatha kugawidwa ngati chotchinga cha nthunzi chosasunthika. Kutalika kwa moyo wake kumatha kupitilira zaka 70 mukugwiritsa ntchito izi. M'lifupi akhoza kufika kupitirira 8m ndi kutalika akhoza kufika kuposa 800m.

Kutsimikizira kwachinyezi ndi gawo lofunika kwambiri kuti nyumbayo ikhale yokhazikika popanga zomangamanga. Katundu wathu wosinthika komanso wabwino wosasunthika wa chotchinga chathu cha chinyezi cha polyethylene chatsimikizika pama projekiti ambiri otchingira nthunzi pansi ndi makoma mobwerezabwereza.
Pamtengo wotchinga mpweya wa polyethylene, mutha kulangiza malonda athu malinga ndi chida chathu chochezera pa intaneti kapena kulumikizana kwina.
