Kusankha Zinthu Zapamwamba Kwambiri Zopangira Ma Sandwich Panels: Kulinganiza kwa Kuteteza, Kukana Moto, ndi Mphamvu

Ponena za kapangidwe ka sandwich panel, kusankha zinthu zoyenera zapakati ndikofunikira kwambiri kuti zitsimikizire kuti zinthuzo zikugwira ntchito bwino pankhani ya kutentha, kutchinjiriza mawu, kuteteza moto, komanso mphamvu. Zinthu zapakati zimasiyana kapangidwe kake, chilichonse chimapereka ubwino wake kutengera zomwe zimagwiritsidwa ntchito.

Mapanelo a Thovu

Mitsempha ya thovu, makamakapolyurethane(PUR) ndi polyisocyanurate (PIR), ndi zina mwa zosankha zodziwika bwino pa mapanelo a masangweji.PolyurethaneMapanelo apakati amapereka mphamvu zabwino kwambiri zotetezera kutentha, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pomwe kugwiritsa ntchito mphamvu moyenera ndikofunikira kwambiri. Komabe, kukana kwawo moto kuli kochepa poyerekeza ndi zipangizo zina. Pofuna kuthana ndi izi, mapanelo a PIR adapangidwa ngati mtundu wabwino wa PUR, womwe umapereka kukana moto, kutetezera kutentha, komanso kukhazikika. Mapanelo a PIR ndi oyenera ntchito zamafakitale komanso zapakhomo zomwe zimafuna chitetezo chapamwamba pamoto.

Zipangizo za thovu la phenolic (PF), ngakhale kuti ndi zodula kuposa PUR ndi PIR, zimapereka mphamvu yolimbana ndi moto komanso kutentha kwambiri. Mapanelo amenewa nthawi zambiri amasankhidwa pamene chitetezo cha moto chili chofunika kwambiri, ngakhale kuti mtengo wokwera ukhoza kukhala chinthu chofunikira kuganizira m'mapulojekiti omwe amaganizira bajeti.

Mapanelo a polystyrene foam core, makamaka polystyrene yowonjezeredwa (EPS) ndi extruded (XPS), amapereka njira ina yotsika mtengo. Mapanelo a EPS amagwiritsidwa ntchito kwambiri m'mapulojekiti omwe amawononga ndalama zambiri koma amapereka kukana kutentha ndi moto pang'ono kuposa PUR kapena PIR. Komabe, XPS ili ndi kukana kwakukulu, komwe kumapereka kukana kutentha, chinyezi, ndi nthunzi kuposa EPS, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri m'malo omwe nthawi zambiri amakhala ndi chinyezi.

Mapanelo Opanda Thovu

Pa ntchito zomwe kukana moto ndi kutchinjiriza mawu ndizofunikira kwambiri, ma panel a ubweya wa mchere ndi ofunikira kwambiri. Ubweya wa mchere ndi chinthu chosayaka, chomwe chimapereka chitetezo chabwino kwambiri pamoto komanso mphamvu zabwino kwambiri zotetezera mawu. Komabe, ndi wolemera kuposa PIR ndipo uli ndi kutchinjiriza pang'ono kwa kutentha, zomwe zimapangitsa kuti ukhale woyenera kwambiri pamapulojekiti omwe kukana moto kumayikidwa patsogolo kuposa kugwiritsa ntchito bwino kutentha.

Mapanelo a Uchi

Mapangidwe a uchi, omwe nthawi zambiri amapangidwa ndi aluminiyamu, polypropylene, kapena khadibodi, amadziwika kuti ndi amphamvu kwambiri poyerekeza ndi kulemera, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito mphamvu zamakina. Komabe, sapereka mulingo wofanana wa kutentha monga mapanelo okhala ndi thovu, zomwe zimapangitsa kuti asagwiritsidwe ntchito bwino pa ntchito zomwe kutentha kumakhala kofunikira kwambiri.

Mwachidule, kusankha zinthu zofunika kwambiri kumadalira zofunikira za polojekitiyi. Ma PUR ndi PIR cores ndi abwino kwambiri poteteza kutentha, pomwe ubweya wa mchere umapambana pakulimbana ndi moto komanso kuteteza phokoso. Pa ntchito zolimbitsa mphamvu, ma vis cores angakhale oyenera kwambiri, ngakhale kuti alibe mphamvu zotetezera kutentha. Chida chilichonse chapakati chimapereka zabwino zake, ndipo chisankho chabwino kwambiri chimadalira momwe zinthu zimagwirira ntchito bwino monga kuteteza kutentha, chitetezo cha moto, komanso kulimba kwa kapangidwe kake.
