Njengesixhobo sokukhusela izakhiwo esonga amandla, iphaneli yesandwich ye-polyurethane ibe yinxalenye ebalulekileyo yezityalo zoshishino zanamhlanje, iindawo zokugcina izinto, kunye neendawo zokugcina izinto ezibandayo. Olu hlobo lwephaneli yokwakha, oludibanisa iileya zomphezulu wesinyithi kunye nezinto ze-polyurethane, kulindeleke ukuba lube lubaluleke ngakumbi kwixesha elizayo.
Ukusebenza Okugqwesileyo
Inzuzo ephambili yephaneli yesandwich ye-polyurethane ikwindlela esebenza ngayo ngokugqwesileyo ekugqumeni ubushushu. Izinto ze-polyurethane foam zineempawu ezilungileyo zokugquma ubushushu, kunye nokuqhuba kobushushu okuphantsi njenge-0.017-0.025 W/(m·K). Oku kuthetha ukuba iphaneli enobukhulu obuziisentimitha ezi-5 kuphela inokufezekisa isiphumo esifanayo sokugquma njengodonga lwekhonkrithi oluyimitha enye. Ngenxa yokusebenza kwayo okugqwesileyo kokugquma, iiphaneli zesandwich ze-polyurethane ziye zaba zezona zinto zikhethwayo zokwakha iindawo zokugcina izinto ezibandayo.
Ukuthintela ukungenwa kwamanzi, ukumelana nokufuma, kunye nozinzo oluphezulu zezinye iingenelo zeepaneli zesandwich ze-polyurethane. Izinga leeseli ezivaliweyo zesiseko se-polyurethane foam lidlula i-95%, nto leyo ethintela ngempumelelo ukungena komswakama. Izinga lokufunxwa kwamanzi kweepaneli zesandwich ze-polyurethane lingaphantsi kwe-3%. Kwangaxeshanye, phantsi kotshintsho lobushushu obuyi-30°C, utshintsho lobukhulu beepaneli lungaphantsi kwe-1%, nto leyo eqinisekisa ukusetyenziswa ixesha elide ngaphandle kokuguquka.
Ukumelana nomlilo kweepaneli zesandwich ze-polyurethane kunokufikelela kwiKlasi B1. Iipaneli zesandwich ze-polyurethane ziyatsha, kodwa ziyayeka ukutsha emva kwemizuzwana emi-3 emva kokuba zisusiwe elangatyeni. Nangona zingaphantsi kancinci kuneepaneli zesandwich ze-rock wool kule nkalo, zisahlangabezana neemfuno ezisisiseko zokhuseleko lomlilo.
Ngokwesakhiwo, ngenxa yeengqimba ezimbini zeephaneli zesinyithi phezulu nasezantsi, iiphaneli zesandwich ze-polyurethane zinamandla amahle esakhiwo. Amandla okuxinwa kweephaneli zesandwich ze-polyurethane angaphezu kwe-150 kPa. Nangona kunjalo, izinto eziphambili yi-polyurethane foam, eyenza iiphaneli zibe lula ngama-30-60% kuneemveliso zemveli. Oku kwenza iiphaneli zesandwich ze-polyurethane zibe zezona zinto zikhethwayo zokwakha ezikhaphukhaphu.
Imfuno Ephezulu Yemveliso
Okwangoku, inkqubo yokuvelisa iiphaneli zesandwich ze-polyurethane izenzekelayo kakhulu. Abavelisi abaphambili, abanjengoHarbin Dong'an Building Sheets Co., Ltd., basebenzisa imigca yemveliso eqhubekayo ukudibanisa yonke inkqubo yokufaka igwebu, ukunyanga, kunye nokubumba iiphaneli.
Ukwenziwa kwefoam enoxinzelelo oluphezulu linyathelo elibalulekileyo ekuvelisweni kweepaneli zesandwich ze-polyurethane. Umgangatho wefoam umisela ngokuthe ngqo ukusebenza kweepaneli. Ngexesha lokuveliswa, abavelisi kufuneka balawule ngokuchanekileyo ubushushu bebhodi yetyathanga kunye nezinto zokwenziwa kwefoam. Isantya somgca wemveliso naso sibalulekile, njengoko sichaphazela ukufana kwenkqubo yokwenziwa kwefoam engundoqo.
