Nyumba zamakono zimafunikira zipangizo zomwe zimasunga mphamvu ndikukhala zolimba komanso zoteteza kutenthamapanelo a masangwejiAmakwaniritsa izi. Amaphatikiza kutentha, kapangidwe, ndi kapangidwe kake mu dongosolo limodzi. Omanga amagwiritsa ntchito izi popanga nyumba zosungiramo zinthu, mafakitale, ndi zipinda zozizira.
Mapanelo amagwira ntchito bwino m'nyengo ndi mikhalidwe yosiyanasiyana. Amapanga ma envelopu omangira nyumba okhazikika komanso osagwiritsa ntchito mphamvu zambiri. Kugwiritsa ntchito bwino kutentha kwawo komanso chitetezo cha moto zimapangitsa kuti akhale abwino kwambiri pamapulojekiti amakono.
Ntchito ya Mapanelo a Sandwichi Otetezedwa
Chipinda chilichonse chosungiramo zinthu zotenthetsera chili ndi mapepala awiri achitsulo okhala ndi pakati pake potenthetsera. Kapangidwe kameneka kamachepetsa kutentha ndipo kamakhala kolimba kwambiri.
Ma sandwich panels otetezedwa amagwira ntchito zosiyanasiyana mu zomangamanga zamakono. Ntchito yawo yayikulu ndikulamulira kutentha mkati mwa nyumba. Choteteza kutentha chimachepetsa kutaya kutentha nthawi yozizira komanso kutentha kwambiri nthawi yachilimwe. Izi zimachepetsa kugwiritsa ntchito mphamvu potenthetsera ndi kuziziritsa. Kafukufuku akuwonetsa kuti nyumba zomwe zimagwiritsa ntchito ma sandwich panels otetezedwa zimatha kusunga mphamvu 30% mpaka 50% poyerekeza ndi makoma wamba.
Amachepetsanso kufalikira kwa phokoso. Mafakitale ambiri ndi malo ogwirira ntchito amafuna malo ogwirira ntchito chete. Kapangidwe ka gululi kolimba kamatseka phokoso bwino. Gulu la polyurethane la 50 mm limatha kuchepetsa phokoso ndi pafupifupi 25 dB.
Ntchito ina yofunika kwambiri ndi chitetezo. Pamwamba pa chitsulocho pamatha kupirira mphepo, mvula, ndi dzimbiri. Chimateteza zinthu zotetezera kutentha ndipo chimasunga dongosololo kukhala lolimba. Mbali yakunja yolimba imalola mapanelo kuti azitha kunyamula katundu wolemera. Izi zimathandiza kuti azikhala kwa zaka zambiri popanda kukonza kwambiri.
M'malo osungiramo zinthu ozizira komanso m'zipinda zoyera, mapanelo amasunga kutentha ndi ukhondo nthawi zonse. Amaletsa chinyezi ndi kukula kwa mabakiteriya kudzera m'malo awo osalala, opanda mabowo. Malo olumikizirana pakati pa mapanelo ndi olimba, zomwe zimathandiza kuti mpweya uzitseke bwino.
Akatswiri opanga mapulani amagwiritsa ntchito mapanelo awa popanga nyumba zosagwiritsa ntchito mphamvu zambiri, zopepuka, komanso zolimba. Dongosololi limaphatikiza kutentha, kapangidwe, ndi kukongola. Omanga amasunga nthawi chifukwa mapanelo amapangidwa kale ndi miyeso yokhazikika. Chidutswa chilichonse chimatha kukwanira mwachangu pamalopo, zomwe zimachepetsa ndalama zogwirira ntchito.
Makhalidwe Ofunika
Ma sandwich panels otetezedwa ali ndi makhalidwe angapo odziwika bwino. Kuteteza kwawo kutentha kumakhala chinthu chofunikira kwambiri. Pakati pake nthawi zambiri amagwiritsa ntchito polyurethane (PU), polyisocyanurate (PIR), kapena ubweya wa miyala. Chilichonse chimakhala ndi kutentha kosiyana.
Mapanelo a PU ali ndi mphamvu yoyendetsera kutentha ya pafupifupi 0.022 W/m·K, zomwe zikutanthauza kuti amateteza bwino kwambiri. Ma PIR cores amapereka mphamvu yolimba kwambiri komanso mphamvu zofanana.
Mapanelo amaperekanso mphamvu zambiri zamakanika. Zikopa zachitsulo zimagawana katundu ndi pakati, zomwe zimapangitsa kuti zikhale zokhazikika. Panel ya PU yokhala ndi makulidwe a 100 mm imatha kupirira kupanikizika mpaka 150 kPa. Mphamvu imeneyi imawapangitsa kukhala oyenera madenga, makoma, ndi zipinda zozizira.
Chinthu china chofunikira ndi kukana moto. Ma PIR ndi ma rock wool cores amatha kupeza ma Class B1 kapena Class A milingo ya moto. Amachedwetsa kufalikira kwa moto ndikuchepetsa kutulutsa utsi. Mwachitsanzo, gulu la rock wool la 75 mm limatha kukana moto kwa mphindi zoposa 60.
Kulimba kwawo n'kodabwitsanso. Mapepala achitsulo, omwe nthawi zambiri amakhala achitsulo cholimba kapena chopakidwa utoto, amalimbana ndi dzimbiri komanso chinyezi. Opanga ambiri amagwiritsa ntchito zokutira za polyester kapena PVDF kuti azitha kukhala ndi moyo kwa zaka zoposa 20.
Kuphatikiza apo, mapanelo awa amapereka mawonekedwe osiyanasiyana okongola. Amabwera mumitundu yosiyanasiyana, ma profiles, ndi ma finishes. Malo osalala, okhala ndi mikwingwirima, kapena ojambulidwa amatha kufanana ndi kapangidwe kosiyanasiyana.
Pomaliza, kusavuta kukhazikitsa kumawonjezera phindu. Ma panel ndi opepuka komanso osavuta kugwiritsa ntchito. Omanga amagwiritsa ntchito zomangira zobisika ndi makina olumikizirana kuti apange mizere yoyera. Izi zimachepetsa nthawi yomanga ndikutsimikizira kuti imamalizidwa bwino.
Chisamaliro cha Kupanga
Kupanga mapanelo a sandwich otetezedwa kumafunika kulamulira mwamphamvu. Gawo lililonse limakhudza magwiridwe antchito ndi ubwino. Opanga amayamba ndi mapepala achitsulo apamwamba. Chitsulocho chiyenera kukhala ndi zinc yokwanira kuti chipewe dzimbiri. Kukhuthala nthawi zambiri kumakhala pakati pa 0.4 mm ndi 0.8 mm kutengera kapangidwe kake.
Kenako pamabwera kukonza pamwamba. Pamwamba pa chitsulo payenera kukhala paukhondo komanso pouma musanapake utoto. Mafuta, fumbi, kapena dzimbiri lililonse likhoza kusokoneza kumatirira. Chophimba chapamwamba kwambiri, monga PVDF kapena polyester, chimawonjezera kukana kwa nyengo.
Chipinda chotetezera kutentha chimafuna kapangidwe kolondola ka zinthu. Pa PU ndi PIR, chiŵerengero cha mankhwala ndi kuwongolera kutentha ndizofunikira kwambiri. Ngakhale cholakwika chochepa chingachepetse kuchulukana kwa thovu kapena kupanga mipata. Mapanelo a ubweya wa miyala amafunika kuyang'aniridwa bwino kwa ulusi ndi kuchulukana kuti asawonongeke ndi moto.
Pakupanga kosalekeza, thovu kapena zinthu zapakati zimalowa pakati pa mapepala achitsulo. Njirayi imafunika kupanikizika kolondola komanso kuwongolera liwiro. Kusalinganika kwa lamination kumatha kufooketsa mgwirizano pakati pa pakati ndi khungu. Mizere yopangira yapamwamba imagwiritsa ntchito makina otenthetsera ndi kupanikizika kuti zitsimikizire kuti zinthuzo ndi zabwino mofanana.
Kutseka kodula ndi m'mphepete kumafunikanso kusamalidwa. Malumikizidwe a mafundowa amatsimikizira kutentha ndi kulimba kwa mpweya. Mpata wochepa ungayambitse kuzizira ndi kutuluka kwa kutentha. Opanga nthawi zambiri amagwiritsa ntchito zolumikizira za lilime ndi groove kapena zomangira zobisika kuti akonze kutseka.
Kuwunika khalidwe kumamaliza ntchitoyi. Magulu amayesedwa kuti awone ngati ali ndi makulidwe, kuchulukana, kumamatira, mphamvu yopindika, komanso momwe moto umayendera. Deta imatsimikizira kuti chinthucho chikukwaniritsa miyezo ya dziko lonse komanso yapadziko lonse lapansi.
Kuyika ndi kunyamula bwino mapanelo kumateteza mapanelo musanawayike. Kuwonongeka kwa makina panthawi yopereka kumatha kuwononga m'mbali kapena chophimba. Chifukwa chake, mapanelo amaikidwa m'mizere yosalala ndikukulungidwa ndi filimu yoteteza.
Ndemanga za polojekiti
Harbin Dong`an Building Sheets Co., LtdKampani ya Dong`an ili ndi mapulojekiti ambiri enieni a mapanelo a sandwich omwe amatetezedwa ndi kutentha. Mapulojekitiwa akuwonetsa mphamvu ya mapanelo a sandwich omwe amatetezedwa ndi kutentha.
Mu nyumba yosungiramo zinthu yomangidwa ku Malaysia, mainjiniya adagwiritsa ntchito mapanelo a PIR a 100 mm padenga ndi 75 mm pamakoma. Nyumbayi idasunga mphamvu ndi 45% poyerekeza ndi makoma achikhalidwe otetezedwa ndi insulation. Kutentha kwa mkati kunakhalabe kokhazikika mkati mwa ±2 °C ngakhale dzuwa litalowa.
Chomera chosungiramo zinthu zozizira ku Philippines chinagwiritsa ntchito mapanelo a PU a 150 mm m'zipinda zoziziritsira. Kutentha kwamkati kunakhalabe pa −25 °C ndi kusinthasintha kwa 3 °C kokha patsiku. Kugwiritsa ntchito mphamvu kunatsika ndi 30% mutasintha ma board akale otetezera kutentha.
Ku Ulaya ndi ku Russia, mapanelo a sandwich a ubweya wa miyala ndi otchuka m'mafakitale chifukwa cha chitetezo cha moto. Malo ogwirira ntchito okhala ndi 1,200 m² pogwiritsa ntchito mapanelo a ubweya wa miyala a 80 mm anakwaniritsa miyezo ya moto ya EN 13501 Class A. Kukana moto kunatenga mphindi zoposa 90 m'mayesero.
Omanga nyumba amagwiritsanso ntchito mapanelo awa kuti azigwiritsidwa ntchito popanga nyumba zosagwiritsa ntchito mphamvu zambiri. Nyumba yaying'ono yokhala ndi mapanelo a PU a 50 mm imatha kufika pa coefficient yosinthira kutentha (U-value) ya 0.38 W/m²·K. Mlingo uwu ukugwirizana ndi miyezo yambiri ya nyumba zopanda mphamvu.
Ma sandwich panel otetezedwa amaphatikiza kutchinjiriza, mphamvu, ndi kapangidwe kake mu dongosolo limodzi lothandiza. Amathandiza nyumba zamakono kusunga mphamvu ndikukhalabe zolimba. Amayimira njira yolinganiza pakati pa kuchita bwino, chitetezo, ndi kapangidwe kamakono ka tsogolo la zomangamanga. Pamene zomangamanga zokhazikika zikukula, ma sandwich panel otetezedwa adzapindula kwambiri.
