Puf panel imagwiritsidwa ntchito kwambiri pomanga, kusungiramo zinthu zozizira, nyumba zamafakitale, ndi nyumba zomangidwa modular, chifukwa cha mphamvu zawo zoteteza kutentha komanso liwiro la kukhazikitsa. Ngakhale akatswiri omanga nyumba ndi omanga nyumba amayamikira magwiridwe antchito awo, mitengo imasiyana kwambiri kutengera zinthu zingapo zomwe zingathe kuwerengedwa.
Kukhuthala kwa gulu ndi magwiridwe antchito a kutchinjiriza
Kukhuthala kwa pakati pa PU sandwich panel kumagwirizana mwachindunji ndi mtengo wake. Kukhuthala kokhazikika kumayambira pa 40 mm mpaka 250 mm, ndipo mapanelo okhuthala amapereka kutentha kwabwino (mtengo wotsika wa U) koma amafunikira zinthu zopangira zambiri.
Bokosi la Puf la 100 mm nthawi zambiri limadula 20-30% kuposa 50 mm chifukwa cha kuchuluka kwa thovu la polyurethane komanso R-value yabwino, zomwe zingachepetse kwambiri kutentha ndi kuziziritsa katundu pa moyo wonse wa nyumbayo.
Kugwiritsa ntchito bwino kutentha kumakhudza mtengo chifukwa kukwaniritsa kutentha kochepa (pafupifupi 0.022 W/m·K ya PU) kumafuna kupangidwa kwa thovu molondola komanso kuwongolera khalidwe.
Zinthu Zapakati ndi Kuchulukana
Polyurethane yokha ndiyo imabweretsa ndalama zambiri. Kapangidwe ka maselo otsekedwa a thovu la PU kamapereka chitetezo chabwino kwambiri poyerekeza ndi njira zina monga EPS (expanded polystyrene), koma zipangizo zake zopangira—polyols ndi isocyanates—ndi zinthu zopangidwa ndi petrochemical zomwe zimakhala ndi mitengo yosasinthasintha. Deta yamakampani ikuwonetsa kuti ndalama zopangira zopangira zimakhala 60–70% ya ndalama zonse zopangira mapanelo.
Kuphatikiza apo, kuchuluka kwa thovu kumakhudza magwiridwe antchito komanso mtengo. PU yochuluka kwambiri imapereka mphamvu yabwino yamakina komanso kutentha kochepa koma imawonjezera mtengo chifukwa cha kugwiritsidwa ntchito kwambiri kwa zinthu ndi kukonza kovuta. Puf panel yokhala ndi kuchuluka kwapakati imatha kuwononga ndalama zokwana 15–25% kuposa mitundu yocheperako.
Zipangizo Zoyang'ana Pakhomo
Ma panelo a masangweji amakhala ndi PU core yolumikizidwa pakati pa mbali ziwiri zachitsulo. Izi zitha kukhala chitsulo chopangidwa ndi galvanized, chitsulo chopakidwa kale, kapena aluminiyamu. Opanga ena otsogola, monga Harbin Dongan Building Sheets Company, amapereka mapanelo a puf okhala ndi mapanelo a Al-Mg-Mn, zomwe zingapangitse kuti panelo la masangweji likhale lopepuka, losagwira dzimbiri, komanso lolimba.
Chitsulo cholimba cha galvanized ndiye chinthu chotsika mtengo kwambiri chomwe chimayang'ana pamwamba ndipo chimapereka chitetezo chokwanira ku dzimbiri, pomwe chitsulo chopakidwa kale chokhala ndi PVDF kapena polyester chimawonjezera kulimba ndi kukongola. Zachidziwikire, izi zidzawonjezera mtengo wopanga. Mafelemu a aluminiyamu ndi opepuka komanso opirira dzimbiri koma adzakhala okwera mtengo kwambiri kuposa chitsulo.
Kukhuthala kwa zikopa zachitsulo n'kofunikanso. Kawirikawiri, makulidwe a chikopa chachitsulo ndi 0.4-0.6 mm. Kampani ya Dongan imatha kupereka mapanelo okhala ndi makulidwe a zikopa zachitsulo a 0.8 mm. Khungu lokhuthala limathandizira kuuma kwa mapanelo a puf komanso kugwira ntchito bwino, zomwe zikutanthauzanso mtengo wokwera.
Ziwerengero za Moto ndi Miyezo ya Chitetezo
Mapanelo a Standard Puf nthawi zambiri amakhala ndi ziwongola dzanja zochepa pa moto monga Euro class E. Komabe, mapulojekiti, monga nyumba za anthu onse, masukulu, zipatala, amafuna chitetezo chapamwamba. Mapanelo omwe amakwaniritsa magwiridwe antchito apamwamba a moto amafuna mitundu yapadera yoletsa moto kapena ma cores ena, monga PIR, zomwe zimapangitsa kuti kupanga kukhale kovuta komanso mtengo wake.
Zipangizo Zopangira Ma Sandwich Panels
Zipangizo zopangira zinthu zimakhudza kwambiri ubwino wa mapanelo a sandwich. Mzere wopangira wapamwamba komanso wophatikizika ungatsimikizire bwino kuti thovu la polyurethane core ndi kuphatikiza kwa mbale yachitsulo ya core.
Kusintha ndi Zinthu Zapadera
Mapanelo a PU okhazikika ndi otsika mtengo chifukwa cha kupanga kwawokha. Kukula kwapadera, mawonekedwe apadera, ma profiles apadera a m'mphepete, kapena zokutira zapamwamba za UV, anti-condensation, kapena zomalizidwa ndi zomangamanga zimawonjezera mtengo.
Mwachitsanzo, kuwonjezera pa zachizolowezimapanelo a masangwejiKampani ya Dongan ingaperekenso mapanelo okongoletsera a masangweji. Makasitomala amatha kusankha, kapena kusintha, kapangidwe ka khungu lachitsulo malinga ndi zomwe amakonda komanso kalembedwe ka nyumbayo. Kupanga mapangidwe okonzedwa kumatanthauza kuti payenera kupangidwa nkhungu yachitsulo yosiyana, ndipo mtengo wa nkhunguyo udzawonekeranso pamtengo wa chinthu chomalizidwa.
