Iphaneli yePuf isetyenziswa kakhulu ekwakheni, kwindawo yokugcina izinto ezibandayo, kwizakhiwo zoshishino, nakwizakhiwo eziziimodyuli, ngenxa yokusebenza kwazo okuphezulu kokugquma kunye nesantya sokufakelwa. Ngelixa abakhi bezakhiwo kunye nabakhi beyixabisa indlela esebenza ngayo, amaxabiso ayahluka kakhulu ngokusekelwe kwizinto ezininzi ezinokulinganiswa.
Ubukhulu bePaneli kunye nokusebenza kwe-Insulation
Ubukhulu bombindi wepaneli yesandwich ye-PU buhambelana ngqo nexabiso layo. Ubukhulu obuqhelekileyo buqala kwi-40 mm ukuya kwi-250 mm, kunye neepaneli ezityebileyo ezibonelela ngobushushu obungcono (ixabiso eliphantsi le-U) kodwa zifuna izinto eziluhlaza ezingaphezulu.
Iphaneli yePuf eyi-100 mm idla ngokubiza ngaphezulu kwama-20–30% kune-50 mm elinganayo ngenxa yokwanda komthamo wefoam ye-polyurethane kunye nexabiso eliphuculweyo le-R, nto leyo enokunciphisa kakhulu imithwalo yokufudumeza nokupholisa kumjikelo wobomi besakhiwo.
Ukusebenza kakuhle kobushushu kunefuthe kwixabiso kuba ukufikelela kwi-thermal conductivity ephantsi (malunga ne-0.022 W/m·K ye-PU) kufuna ukwenziwa kwe-foam ngokuchanekileyo kunye nolawulo lomgangatho.
Izinto ezingundoqo kunye noxinano
I-Polyurethane ngokwayo inegalelo elikhulu kwindleko. Ulwakhiwo lwe-PU foam oluqinileyo oluvaliweyo lubonelela ngobushushu obuhle kakhulu xa kuthelekiswa nezinye iindlela ezifana ne-EPS (i-polystyrene eyongeziweyo), kodwa izinto zayo ezikrwada—ii-polyols kunye nee-isocyanates—zizinto eziphuma kwi-petrochemical derivatives ezinamaxabiso aguquguqukayo. Idatha yeshishini ibonisa ukuba iindleko zezinto ezikrwada zenza i-60–70% yeendleko zemveliso zephaneli iyonke.
Ukongeza, uxinano lwefoam luchaphazela zombini ukusebenza kunye nexabiso. I-PU enoxinano oluphezulu inika amandla angcono oomatshini kunye nokuguga okuphantsi kobushushu kodwa inyusa iindleko ngenxa yokusetyenziswa okukhulu kwezinto kunye nobunzima bokucubungula. Iphaneli ye-Puf enoxinano oluphezulu lwe-core inokubiza ngaphezulu kwe-15-25% kuneenguqulelo ezinoxinano oluphantsi.
Izinto zokujongana
Iiphaneli zesandwich zenziwe nge-PU core ebotshelelwe phakathi kwee-facings ezimbini zesinyithi. Ezi zinokuba yintsimbi egalelweyo, intsimbi epeyintwe kwangaphambili, okanye i-aluminium. Abanye abavelisi abaphambili, njengeHarbin Dongan Building Sheets Company banikezela ngephaneli ye-puf eneephaneli ze-Al-Mg-Mn, ezinokwenza iphaneli yesandwich ibe lula, ikwazi ukumelana nokugqwala, kwaye ibe namandla.
Intsimbi esisiseko egalelweyo yeyona nto ibiza kakhulu kwaye inika ukumelana nokugqwala okwaneleyo, ngelixa intsimbi epeyintwe kwangaphambili enePVDF okanye i-polyester coatings yongeza ukuqina kunye nobuhle. Kakade ke, iya kunyusa iindleko zokuvelisa. Ii-aluminium facings zikhaphukhaphu kwaye azinamhlwa kodwa ziya kubiza kakhulu kunentsimbi.
Ubukhulu bezikhumba zesinyithi nabo bubalulekile. Ngokubanzi, ubukhulu bezikhumba zesinyithi buyi-0.4-0.6 mm. Inkampani yaseDongan inokubonelela ngeephaneli ezinobukhulu bezikhumba zesinyithi obuyi-0.8 mm. Ulusu olutyebileyo luphucula ukuqina kweephaneli ze-puf kunye nokusebenza kakuhle kokuthwala umthwalo, nto leyo ethetha ukuba ixabiso liphezulu.
Imigangatho yoKhuseleko kunye neMigangatho yoMlilo
Iphaneli yePuf esemgangathweni idla ngokufikelela kumanqanaba omlilo aphakathi afana ne-Euro class E. Nangona kunjalo, iiprojekthi, njengezakhiwo zikawonke-wonke, izikolo, izibhedlele, zifuna amanqanaba okhuseleko aphezulu. Iiphaneli ezihlangabezana nokusebenza okuphezulu komlilo zifuna iifomyula ezikhethekileyo ezithintela umlilo okanye ezinye iicores, ezifana ne-PIR, nto leyo eyonyusa ubunzima bemveliso kunye neendleko.
Izixhobo zokuvelisa iiphaneli zesandwich
Izixhobo zemveliso zinempembelelo enkulu kumgangatho weepaneli zesandwich. Umgca wemveliso ophucukileyo nodibeneyo unokuqinisekisa ngcono ukugqwala okufanayo kwezinto eziphambili zepolyurethane kunye nokudityaniswa kwepleyiti yesinyithi yezinto eziphambili.
Ukwenza ngokwezifiso kunye neempawu ezikhethekileyo
Iiphaneli zePU eziqhelekileyo zibiza kancinci ngenxa yemveliso ezenzekelayo. Ubungakanani obulungiselelwe wena, iimilo ezizodwa, iiprofayili zomphetho ezikhethekileyo, okanye iingubo eziphambili ze-UV, i-anti-condensation, okanye ukugqitywa kwezakhiwo zongeza ixabiso.
Umzekelo, ukongeza kwi-ordinaryiiphaneli zesandwich, Inkampani yaseDongan inokubonelela ngeepaneli zesandwich zokuhombisa. Abathengi banokukhetha, okanye bade benze ngokwezifiso, ipateni yesikhumba sesinyithi ngokwezinto abazikhethayo kunye nesimbo sesakhiwo. Ukuveliswa kweepateni ezenziwe ngokwezifiso kuthetha ukuba kufuneka kwenziwe isikhunta sesinyithi esahlukileyo, kwaye ixabiso lesikhunta liya kubonakala nakwixabiso lemveliso egqityiweyo.
