Bututun samar da iska na gargajiya na kwandishan na tsakiya yawanci ana yin shi ne da takardar ƙarfe ko fiber gilashin da aka ƙarfafa filastik a saman rufin ciki, an nannade shi da kayan kariya na thermal, kuma an nannade shi da foil na aluminum a saman Layer na waje, wanda ke sa bututun iskar ya yi nauyi cikin nauyi. , Yin aiki da cin lokaci a cikin gine-gine da shigarwa, rashin kyau a bayyanar, ƙananan ƙarancin iska da yawan amfani da makamashi.Idan aka kwatanta da bututun iska na gargajiya, phenolic composite air ducts suna da fa'idodi masu zuwa:
1. Kyau mai kyau na thermal, wanda zai iya rage yawan zafi na na'urar kwandishan
A thermal watsin na phenolic composite iska bututu ne 0.016 ~ 0.036w / (m · K), yayin da thermal watsin na galvanized karfe bututu da kuma FRP duct ya fi girma.Bugu da ƙari, yanayin haɗin kai na musamman na phenolic composite air duct yana tabbatar da kyakkyawan yanayin iska na tsarin iska, wanda yake kusa da sau 8 na galvanized karfe duct.Wasu bayanai sun nuna cewa lokacin da aka watsa nau'in zafi (sanyi), asarar zafi na bututun ƙarfe na galvanized ya kai 15%, asarar zafi na bututun FRP shine 8%, da asarar zafi na iska mai rufin kumfa. bututu bai wuce 2% ba.
2. Kyakkyawan shiru.
The interlayer na phenolic aluminum tsare tsare iska bututu bango ne perforated phenolic kumfa abu farantin, wanda yana da kyau amo kawar yi.A cikin tsarin kula da iska na tsakiya, amo da ke haifar da na'urar sanyaya iska yayin aiki yana cikin kewayon 50-79db, wanda aka watsa ta bututun samar da iska don samar da hayaniya ta cikin gida.Phenolic aluminum foil composite tube iska kanta mai kyaun bututun muffler ne, kuma babu buƙatar saita na'urorin haɗi na shiru kamar murfin shiru da shiru da gwiwar hannu.
3. Hasken nauyi, zai iya rage nauyin ginin, da sauƙin shigarwa
Nauyin phenolic aluminum foil composite iska bututu ne haske, game da 1.4 kg / m2, yayin da girma nauyi na galvanized karfe takardar iska bututu (0.8 mm lokacin farin ciki) da kuma FRP iska bututu (3 mm lokacin farin ciki) ne 7.08 kg / m2 da 15 ~ 20 kg / m2 bi da bi, wanda zai iya rage nauyin ginin da yawa kuma yana da matukar amfani ga shigar da bututun iska.Lokacin shigarwa, tallafi ɗaya kawai ake buƙata kowane 4 m ko makamancin haka don samun isassun ƙarfin tallafi.Wannan yana rage girman ƙarfin buƙatun tallafi da ratayewa, yana sa sufuri da shigarwa ya dace sosai.
4. Rayuwar sabis mai dorewa da tsayi
Galvanized karfe farantin yana da sauki ga tsatsa a cikin rigar yanayi, yayin da gilashin fiber ƙarfafa filastik yana da sauƙi ga tsufa da lalacewa.Sabili da haka, rayuwar sabis na bututun iska na gargajiya ba shi da tsayi, kusan shekaru 5-10.Rayuwar sabis na rufin rufin da aka nannade ta hanyar bututun iska na gargajiya, irin su gilashin ulu, shekaru 5 ne kawai, yayin da rayuwar sabis na phenolic aluminum foil composite ducts na iska shine aƙalla shekaru 20.Saboda haka, rayuwar sabis na phenolic aluminum foil composite iska bututun iska ya fi sau 3 fiye da na al'ada na iska.Bugu da kari, yawan sake amfani da phenolic aluminum foil composite air duct na iya kaiwa 60% ~ 80%, yayin da da kyar za a iya sake amfani da bututun iska na gargajiya.
5. Rage tsayin bene
Ƙwararren iska na gargajiya yana buƙatar gina ginin rufi a kan wurin, don haka yana buƙatar wani tsayin gini, wanda ya gabatar da ƙarin buƙatu don girman bene na ginin.Phenolic aluminum foil composite iska bututun iska ba ya bukatar a kan-site rufi gini, don haka ba lallai ba ne a ajiye ginin sarari, wanda zai iya rage bene tsawo na ginin.
