Xa kufikwa ekwakhiweni kwepaneli yesandwich, ukukhetha izinto ezisisiseko ezifanelekileyo kubalulekile ukuqinisekisa ukusebenza okufunekayo ngokwemigaqo yokuthintela ubushushu, ukuthintela isandi, ukhuseleko lomlilo, kunye namandla. Izinto ezisisiseko zahlukile ngokwakhiwa kwazo, nganye inika iingenelo ezizodwa kuxhomekeke kwiimfuno ezithile zesicelo.
Iiphaneli zeFoam Core
Ii-Foam cores, ngakumbii-polyurethane(PUR) kunye ne-polyisocyanurate (PIR), zezona zikhethwa kakhulu kwiiphaneli zesandwich.I-PolyurethaneIiphaneli eziphambili zibonelela ngeempawu ezintle kakhulu zokuthintela ubushushu, nto leyo ezenza ukuba zilungele ukusetyenziswa apho ukusebenza kakuhle kwamandla kuyinto ephambili. Nangona kunjalo, ukumelana kwazo nomlilo kuncinci xa kuthelekiswa nezinye izinto. Ukujongana noku, iiphaneli ze-PIR zaphuhliswa njengenguqulelo ephuculweyo ye-PUR, enika ukumelana nomlilo okuphuculweyo, ukuthintela ubushushu, kunye nozinzo. Iiphaneli ze-PIR zilungele ukusetyenziswa kwemizi-mveliso kunye neendawo zokuhlala ezifuna ukhuseleko oluphezulu lomlilo.
Izixhobo eziphambili ze-phenolic foam (PF), nangona zibiza kakhulu kune-PUR kunye ne-PIR, zibonelela ngokumelana nomlilo okungcono ngakumbi kunye nobushushu obuphezulu kancinci. Ezi paneli zihlala zikhethwa xa ukhuseleko lomlilo luyinto ebalulekileyo, nangona iindleko eziphezulu zinokuba yinto eqwalaselwayo kwiiprojekthi ezijongana nohlahlo-lwabiwo mali.
Iiphaneli ze-polystyrene foam core, ngakumbi i-polystyrene enwetshiweyo (EPS) kunye ne-extruded (XPS), zibonelela ngenye indlela engabizi kakhulu. Iiphaneli ze-EPS zisetyenziswa kakhulu kwiiprojekthi ezixabisa kakhulu kodwa zinika ukumelana okuphantsi kobushushu kunye nomlilo kune-PUR okanye i-PIR. I-XPS, kwelinye icala, inoxinano oluphezulu, inika ukumelana okungcono kobushushu, ukufuma, kunye nokumelana nomphunga kune-EPS, nto leyo eyenza ukuba ibe lukhetho oluqinileyo kwiindawo ezinokuba manzi.
Iiphaneli zeCore ezingezizo ezeFoam
Kwizicelo apho ukumelana nomlilo kunye nokuthintela isandi kubaluleke kakhulu, iipaneli eziphambili zoboya beminerali ziyabalasela. Uboya beminerali yinto engatshiyo, enika ukhuseleko oluhle kakhulu kumlilo kunye nokukwazi okuphezulu kokuthintela isandi. Nangona kunjalo, inzima kunePIR kwaye ine-insulation ephantsi yobushushu, nto leyo eyenza ukuba ifaneleke ngakumbi kwiiprojekthi apho ukumelana nomlilo kubekwe phambili kunokusebenza kakuhle kobushushu.
Iiphaneli zeHoneycomb Core
Izakhiwo zehoneycomb, eziqhele ukwenziwa nge-aluminium, i-polypropylene, okanye ikhadibhodi, zaziwa ngomlinganiselo wazo ophezulu wokuqina-ubunzima, nto leyo eyenza ukuba zilungele ukusetyenziswa apho amandla oomatshini abaluleke kakhulu. Nangona kunjalo, aziboneleli ngenqanaba elifanayo lobushushu njengeephaneli ezisekelwe kwi-foam, nto leyo eyenza zingafaneleki kangako kwiiprojekthi apho ubushushu bubaluleke kakhulu.
Ngamafutshane, ukhetho lwezinto eziphambili luxhomekeke kwiimfuno ezithile zeprojekthi. Ii-cores ze-PUR kunye ne-PIR zilungile kakhulu ekugqumeni ubushushu, ngelixa uboya beminerali bugqwesileyo ekumelaneni nomlilo kunye nokukhusela isandi. Kwizicelo ezigxile kumandla, ii-cores zehoneycomb zinokuba zifanelekile ngakumbi, nangona zingenawo amandla okusebenza kakuhle kobushushu. Izinto eziphambili nganye zibonelela ngezibonelelo ezahlukeneyo, kwaye ukhetho olungcono ekugqibeleni luxhomekeke kulungelelwano lweemfuno zokusebenza ezifana nokukhusela, ukhuseleko lomlilo, kunye nokuqina kwesakhiwo.
