Gawo limodzi Mzere wa kanema wopumira
Mafotokozedwe Akatundu
Filimu yopanda madzi komanso yopumira imatchedwanso mtundu watsopano wa zinthu zopanda madzi za polima, chifukwa cha microporous, hydrophobic, mafuta komanso mpweya wosagwira madzi komanso ntchito yotsimikizira mafuta, yakhala ikugwiritsidwa ntchito kwambiri pazachipatala, zamagetsi zolondola, kuunikira kunja kwa LED, magetsi a galimoto, mauthenga. , mankhwala, chitetezo ndi mafakitale ena.
The luso amafuna madzi mpweya mpweya ndi apamwamba kwambiri kuposa ambiri madzi zakuthupi;Kuchokera pamalingaliro abwino, filimu yopumira madzi yopanda madzi imakhala ndi zida zina zopanda madzi zilibe mawonekedwe ogwirira ntchito.
Momwe filimu yowonongeka imagwirira ntchito
M'nyengo ya nthunzi yamadzi, tinthu tating'onoting'ono tamadzi timakhala tating'ono kwambiri, molingana ndi mfundo ya capillary motion, imatha kulowa mkati mwa capillary kupita mbali inayo, kuti ichitike chodabwitsa cholowera.Pamene nthunzi yamadzi imalowa m'malovu amadzi, tinthu tating'onoting'ono timakhala tokulirapo, chifukwa cha kugwedezeka kwa madzi pamwamba pa madzi (mamolekyu amadzi pakati pawo "kukoka ndi kumenyana"), mamolekyu amadzi sangathe kutuluka m'madzi kupita kumbali ina. kuteteza malowedwe a madzi, kuti nthunzi permeable filimu ali ndi madzi ntchito.
Zinthu za filimu yopumira
Ukadaulo wamakanema opumira madzi adayambitsidwa koyamba kuchokera kumayiko aku Europe ndi America, koma njira yopangira zinthu zapakhomo ndi yosiyana, mtundu wamtundu wa wopanga aliyense ndi wosagwirizana, walephera kupanga muyezo wogwirizana.M'malo mwake, filimu yopumira yopanda madzi imapangidwa ndi zigawo zitatu: PP spunbonded sanali nsalu, PE polymer breathable film, PP spunbonded sanali nsalu.Ntchito ya spunbonded sanali nsalu nsalu makamaka kumapangitsanso mavuto ndi hydrostatic kuthamanga ndi kuteteza wosanjikiza pakati (breathable filimu), mpweya weniweni makamaka ndi wosanjikiza pakati PE polima mpweya filimu.
Njira yopanga filimu yopumira
Pakali pano, msika zoweta wothira, kupanga kwenikweni madzi mpweya opanga filimu ndi ochepa kwambiri, mafakitale ambiri kapena ogulitsa kulimbikitsa madzi mpweya mpweya wabwino filimu, pafupifupi owerenga ambiri sanaganize, opanga ena amapereka madzi breathable filimu si. chosalowa madzi.
M'malo mwake, filimu yopumira yamadzi yopanda madzi iyenera kukhala yotsika kwambiri, kukana kutentha kwambiri, odana ndi ukalamba, kuthamanga kwa hydrostatic kupitilira 2 metres.Njira yopangirayi iyenera kukhala ukadaulo wopangidwa ndi matenthedwe, popanda guluu, kotero imatha kufikira kutentha kwa madigiri oposa 110, mphamvu yayikulu komanso yotsutsa kukalamba.Ichi ndiye chinthu chomwe chingakwaniritsedi muyezo wa European Union pakadali pano ku China, ndipo ndiukadaulo waposachedwa kwambiri wapakhomo
