Iphaneli ye-puf isetshenziswa kabanzi ekwakheni, endaweni yokugcina izinto ebandayo, ezakhiweni zezimboni, kanye nasezindlini ezihlanganisiwe, ngenxa yokusebenza kwazo okuphezulu kokushisa kanye nesivinini sokufakwa. Ngenkathi abakhi bezakhiwo nabakhi bekwazisa ukusebenza kwabo, amanani ayahlukahluka kakhulu ngokusekelwe ezicini eziningi ezingabalwa.
Ubukhulu bephaneli kanye nokusebenza kokuvimbela
Ubukhulu bengaphakathi lephaneli yesangweji ye-PU buhlobene ngqo nentengo yayo. Ubukhulu obujwayelekile busukela ku-40 mm kuya ku-250 mm, kanti amaphaneli amakhulu ahlinzeka ngokushisa okungcono (inani eliphansi le-U) kodwa adinga izinto zokusetshenziswa ezengeziwe.
Iphaneli ye-Puf engu-100 mm ngokuvamile ibiza ngaphezu kuka-20-30% kunokulingana okungu-50 mm ngenxa yokwanda kwevolumu ye-polyurethane foam kanye nenani elithuthukisiwe le-R, okunganciphisa kakhulu imithwalo yokushisa nokupholisa phakathi nomjikelezo wokuphila kwesakhiwo.
Ukusebenza kahle kokushisa kuthonya intengo ngoba ukufeza ukuhanjiswa kokushisa okuphansi (cishe u-0.022 W/m·K we-PU) kudinga ukwakheka kwe-foam okunembile kanye nokulawulwa kwekhwalithi.
Izinto Eziyinhloko Nobuningi
I-Polyurethane ngokwayo inegalelo elikhulu ezindleleni. Isakhiwo samaseli avaliwe aqinile e-PU foam sinikeza ukuvikela okuhle kakhulu uma kuqhathaniswa nezinye izindlela ezifana ne-EPS (i-polystyrene enwetshiwe), kodwa izinto zayo zokusetshenziswa—ama-polyol nama-isocyanates—ziyizinto ezisetshenziswa ku-petrochemical ezinamanani aguquguqukayo. Idatha yemboni ikhombisa ukuthi izindleko zezinto zokusetshenziswa zakha u-60–70% wezindleko zokukhiqiza amaphaneli eziphelele.
Ngaphezu kwalokho, ukuminyana kwefoam kuthinta kokubili ukusebenza kanye nentengo. I-PU enobukhulu obuphezulu iletha amandla angcono okusebenza kanye nokuguga okuphansi kokushisa kodwa yandisa izindleko ngenxa yokusetshenziswa okukhulu kwezinto kanye nobunzima bokucubungula. Iphaneli ye-puf enobukhulu obuphezulu ingabiza ngaphezu kuka-15-25% kunezinguqulo ezinobukhulu obuphansi.
Izinto Zobuso
Amaphaneli esandwich aqukethe umongo we-PU ohlanganiswe phakathi kwezinhlangothi ezimbili zensimbi. Lawa angaba yinsimbi ehlanganisiwe, insimbi ependwe ngaphambilini, noma i-aluminium. Abanye abakhiqizi abaphambili, njengeHarbin Dongan Building Sheets Company banikeza iphaneli ye-puf enephaneli ye-Al-Mg-Mn, engenza iphaneli yesandwich ibe lula, imelane nokugqwala kakhudlwana, futhi iqine.
Insimbi eyisisekelo ehlanganisiwe iyona ebiza kakhulu futhi inikeza ukumelana nokugqwala okwanele, kuyilapho insimbi ependwe kusengaphambili ene-PVDF noma i-polyester coating yengeza ukuqina nobuhle. Yiqiniso, izokwandisa izindleko zokukhiqiza. Izinhlangothi ze-aluminium zilula futhi azigqwali kodwa zizobiza kakhulu kunensimbi.
Ubukhulu bezikhumba zensimbi nabo bubalulekile. Ngokuvamile, ubukhulu besikhumba sensimbi bungu-0.4-0.6 mm. Inkampani iDongan inganikeza amaphaneli anobukhulu bezikhumba zensimbi obungu-0.8 mm. Isikhumba esijiyile sithuthukisa ukuqina kwamaphaneli e-puf kanye nokusebenza kahle kokuthwala umthwalo, okusho nentengo ephezulu.
Izilinganiso Zomlilo kanye Nezindinganiso Zokuphepha
Iphaneli ejwayelekile ye-Puf ivame ukuthola izilinganiso zomlilo ezimaphakathi njenge-Euro class E. Kodwa-ke, amaphrojekthi, njengezakhiwo zomphakathi, izikole, izibhedlela, adinga amazinga aphezulu okuphepha. Amaphaneli ahlangabezana nokusebenza okuphezulu komlilo adinga ukwakheka okukhethekile okuvimbela umlilo noma ama-core ahlukile, njenge-PIR, okwandisa ubunzima bokukhiqiza kanye nezindleko.
Imishini Yokukhiqiza Amaphaneli Esandwich
Imishini yokukhiqiza inomthelela omkhulu kwikhwalithi yamaphaneli e-sandwich. Umugqa wokukhiqiza othuthukisiwe nohlanganisiwe ungaqinisekisa kangcono ukugoba okufanayo kwezinto eziyinhloko ze-polyurethane kanye nokuhlanganiswa kwepuleti lensimbi lezinto eziyinhloko.
Ukwenza Ngokwezifiso kanye nezici ezikhethekile
Amaphaneli ajwayelekile e-PU asebenza kahle kakhulu ngenxa yokukhiqizwa okuzenzakalelayo. Osayizi abakhelwe ngokwezifiso, izimo ezihlukile, amaphrofayili akhethekile onqenqemeni, noma izembozo ezithuthukisiwe ze-UV, i-anti-condensation, noma ukuqedwa kwezakhiwo kunezela entengo.
Isibonelo, ngaphezu kwezindlela ezivamileamaphaneli esandwich, Inkampani iDongan ingahlinzeka ngamaphaneli esandwich okuhlobisa. Amakhasimende angakhetha, noma enze ngokwezifiso, iphethini yesikhumba sensimbi ngokwezintandokazi zawo kanye nesitayela sesakhiwo. Ukukhiqizwa kwamaphethini enziwe ngokwezifiso kusho ukuthi kudingeka kwenziwe isikhunta sensimbi esihlukile, futhi izindleko zesikhunta zizobonakala entengo yomkhiqizo oqediwe.
