Njengezinto zokuvikela izakhiwo ezisebenzisa amandla amaningi, iphaneli yesangweji ye-polyurethane isibe yingxenye ebalulekile yezitshalo zezimboni zesimanje, izindawo zokugcina impahla, kanye nezindawo zokugcina izinto ezibandayo. Lolu hlobo lwephaneli yokwakha, oluhlanganisa izendlalelo zensimbi nezinto ze-polyurethane, kulindeleke ukuthi lube lubaluleke kakhulu esikhathini esizayo.
Ukusebenza Okuhle Kakhulu
Inzuzo eyinhloko yephaneli yesandwich ye-polyurethane itholakala ekusebenzeni kwayo okuhle kakhulu kokushisa. Izinto ze-polyurethane foam zinezakhiwo ezinhle zokushisa, kanye nokushisa okuphansi njengo-0.017-0.025 W/(m·K). Lokhu kusho ukuthi iphaneli elinobukhulu obungamasentimitha angu-5 kuphela lingafinyelela umphumela ofanayo wokushisa njengodonga lwekhonkrithi oluyimitha elilodwa. Ngenxa yokusebenza kwalo okuhle kakhulu kokushisa, amaphaneli esandwich ye-polyurethane abe yizinto ezikhethwayo zokwakha izindawo zokugcina ezibandayo.
Ukuvimbela amanzi, ukumelana nomswakama, kanye nokuqina okuphezulu kuyinzuzo eyengeziwe yamaphaneli esandwich e-polyurethane. Izinga lamaseli avaliwe e-polyurethane foam core lidlula ama-95%, okuvimbela ngempumelelo ukungena komswakama. Izinga lokumuncwa kwamanzi kwamaphaneli esandwich e-polyurethane lingaphansi kwama-3%. Ngesikhathi esifanayo, ngaphansi kokushintsha kwezinga lokushisa elingu-30°C, ushintsho lobukhulu bamaphaneli lungaphansi kwama-1%, okuqinisekisa ukusetshenziswa kwesikhathi eside ngaphandle kokuguquka.
Ukumelana nomlilo kwamaphaneli esandwich e-polyurethane kungafinyelela ku-Class B1. Amaphaneli esandwich e-polyurethane ayavutha, kodwa ayayeka ukusha ngemva kwemizuzwana emi-3 nje esusiwe elangeni. Nakuba ephansi kancane kunamaphaneli esandwich e-rock wool kulokhu, asahlangabezana nezidingo zokuphepha emlilweni eziyisisekelo.
Ngokwesakhiwo, ngenxa yezingqimba ezimbili zamaphaneli ensimbi phezulu nangaphansi, amaphaneli esandwich e-polyurethane anamandla amahle esakhiwo. Amandla okucindezela amaphaneli esandwich e-polyurethane angaphezu kuka-150 kPa. Kodwa-ke, izinto eziyinhloko yi-polyurethane foam, okwenza amaphaneli abe lula ngo-30-60% kunemikhiqizo yendabuko. Lokhu kwenza amaphaneli esandwich e-polyurethane abe yinto ekhethwayo yokwakha okulula.
Isidingo Esiphezulu Sokukhiqiza
Njengamanje, inqubo yokukhiqiza amaphaneli esandwich e-polyurethane izenzakalelayo kakhulu. Abakhiqizi abaphambili, njengeHarbin Dong'an Building Sheets Co., Ltd., basebenzisa imigqa yokukhiqiza eqhubekayo ukuhlanganisa yonke inqubo yokufaka igwebu, ukupholisa, kanye nokubumba amaphaneli.
Ukwenziwa kwe-foam enomfutho ophezulu kuyisinyathelo esibalulekile ekukhiqizweni kwamaphaneli e-sandwich e-polyurethane. Ikhwalithi ye-foam inquma ngqo ukusebenza kwamaphaneli. Ngesikhathi sokukhiqiza, abakhiqizi badinga ukulawula ngokunembile izinga lokushisa lebhodi le-chain kanye nezinto zokwenziwa kwe-foam. Ijubane lomugqa wokukhiqiza nalo libalulekile, njengoba lithinta ukufana kwenqubo ye-foam eyinhloko.
